Ancillary devices (hydraulic motors, hydraulic cylinders, etc.) are connected through the valve block. Perform any hydraulic connection when the power unit is not running, or when the hydraulic pump is disengaged. The possibility of error in inter-changing the high pressure supply hose and the low pressure return hose has been eliminated, because the supply side coupling is smaller than the return side. 1-1/4” Hydraulic 1” Hydraulic Outlet Inlet 2.D.1: H llustratIon yDraulIc onnectIons These hose couplings are self-sealing, and care should be taken to ensure complete engagement to prevent partial closure of the check valve in the coupling.

Page 27: Tong Rig-Up & Leveling
Suspend the tong and backup from a location as near to the centre of the drill rotary as possible, and from a location high enough on the mast to ensure easy handlng. The lower the point from which the tong is suspended, the more effort will be required to move the tong to and from the connection point. The suspension line may be extended over a pulley and balanced by a counterweight equal to the weight of the tong and backup, or simply tied off in the derrick to form a dead line. When using a dead line arrangement it is necessary to use a FARR spring hanger assembly (see specification page for recommended spring hanger). This spring hanger compensates for the downward movement of the casing as the thread is made-up, and imparts additional force to the suspension cable: ● a “single spring” hanger typically applies 420 lbs. (191 kg.) to the suspension line for every inch of thread made up ● a “double spring” hanger typically applies 840 lbs. (382 kg.) to the suspension line for every inch of thread made up If you do not know which specific spring hanger is in use, check the specification page in this manual for information on the recommended spring hanger for this application. McCoy Drilling & Completions will not guarantee or specify spring hangers other than what has been supplied by McCoy. Many applications use a lift cylinder for adjusting the height of the tong. Ensure the weight of the lift cylinder is known if it has not been included in the total weight of the tong. All forces upon the suspension line must be considered when calculating necessary strength of the suspension line. The weight of the tong, the weight of the lift cylinder, the weight of the spring hanger, and the force imparted on the suspension line by the spring hanger must all be added together in order to arrive at the total force supported by the suspension line. 2.13 echnicAL AnuAL ecTion onTenTS...
Page 28: Tong Leveling
& FARR® B & o Ackup eTup peRATion Suspension & Restraint Continued: Select your suspension line based upon the total force and the margins of safety dictated by the policies of your company and by established engineering practices. Ultimately, calculating the force on the suspension line and selection of the suspension line is the complete responsibility of the customer. McCoy Drilling & Completions recommends using dual backup (snub) lines of sufficient strength to withstand the force imparted by the maximum rated torque of the tong and backup assembly in use. The snub lines will arrest uncontrolled movement of the tong and backup in the event slipping of the backup jaws. Calculate the force on the snub lines by dividing the maximum torque of the tong by the tong’s torque arm (expressed in feet). For example, an 12,000 lbs.-ft. tong with a 31 inch (2.583 ft.) torque arm will generate 4645.2 lbs. of force against the snub line. Select your snub lines based upon the total force and the margins of safety dictated by the policies of your company and by established engineering practices. Ultimately, calculating the force on the snub line and selection of the snub line is the complete responsibility of the customer. Snub lines must be securely connected to the rear of the tong and backup assembly, and tied off to a suitable anchor. FARR CANADA CORP.

Loosen the 1/2” jam nuts on the adjusting bolts on rigid sling brackets. Completely loosen the adjusting bolts. Turn each adjusting bolt equally until tong hangs level front-to-back. Lock adjusting bolts in place with the jam nuts. Loosen 1/2” hex jam nut be- fore rotating adjustment bolt 2.F.2: t llustratIon evelIng ront Load Cell Configuration The backup is directly coupled to the compression load cell via the backup body paddle. The load cell hanger is simply hung on the paddle and secured through the top of the “U” by a bolt and washer set, and in normal operation does not need to be adjusted or removed. The assembly in the first of the following two illustrations has been configured in the “make-up” configura- tion; to convert the assembly to the “break-out” configuration remove the bolt and washer set securing the load cell holder to the paddle, and move the entire assembly to the other side of the paddle.

Initial Start-up and Break-in Procedure YOUR EQUIPMENT HAS BEEN THOROUGHLY TESTED AND INSPECTED AT THE FACTORY. HOWEVER, WE ADVISE INSPECTION AND TESTING OF YOUR NEW TONG AFTER TAKING POSSESSION IN ORDER TO ELIMINATE THE POSSIBILITY OF SHIPPING DAMAGE. McCoy Completions & Drilling recommends that the following pre-operating tests be performed after receipt from the factory or after extended storage, prior to releasing the tong to operations: ● Perform a complete inspection of all fasteners to ensure none have loosened during transport.

Pushing the valve handle forward will cause the backup to engage. Pulling backward, towards the operator, reverses the operation. 2.g.3: B llustratIon ackup lamp clamp ontrol alve Shifting Gears The shifting shaft has three “detent” positions identifying the low speed/high torque position, the “neutral” or free-spinning posi- tion, and the high speed/low torque position. The detent strength may be adjusted by releasing the locknut on the detent tube and increasing or relaxing pressure on the detent spring. Ensure the locknut is tightened once the desired detent pressure has been set. To shift to the high-speed gear, move the shifting handle upward from neutral position. To shift to the low-speed gear, move the shifting handle down through the neutral detent to its lowest position. Note that the high clutch gear or the low clutch gear may not be exactly aligned when shifting, so the operator may need to “bump” the motor control handle slightly to turn the main clutch gear shaft and shifting collar into alignment. This is most effective when applying a small amount of pressure on the gear...

LW9625 9- ” T & FARR® B & o Ackup eTup peRATion Making A Connection Ensure hydraulic power supply to the tong is energized. The master link on the rigid sling must be used to suspend the tong. Do not suspend the tong directly from the rigid sling. 2.H.1: m llustratIon aster IFtIng THE MASTER LINK MUST BE USED TO SUSPEND THE TONG ASSEMBLY Ensure the backing pin is in the “makeup” position. From the front of the tong, the backing pin correctly configured for makeup will be in the 10 o’clock position (see Illustration 2.H.2 next page). If it is not, simply lift up and place in the correct position (see Illustration 2 next page). The cage plate opening must be aligned with the door opening when setting the backing pin position. Set the position of the backing pin on the backup in exactly the same fashion.
Page 35 LW9625 9- ” T & FARR® B & o eTup peRATion Ackup Making A Connection (Continued) Actuate the lift cylinder control valve to lift the assembly from the drill floor. Pushing the valve toward the center of the tong will retract the lift cylinder to lift the assembly (see Illustration 2.H.3). Note that rig personnel are required to stabilize the tong and backup as it is being lifted so it does not swing and collide with other rig equipment. RIG PERSONNEL MUST STABILIZE THE TONG AS IT IS LIFTED FROM THE DRILL FLOOR 2.H.3: l llustratIon ylInDer ontrol aIse Open the LH tong door followed by the RH tong door, followed by the backup door. Since your equipment is equipped with a safety door, opening the tong doors will inhibit rotation of the cage plate.
Page 36 LW9625 9- ” T & FARR® B & o Ackup eTup peRATion Making A Connection (Continued) Manually engage the threads of the tubing connection being made up. Ensure threads are not cross-threaded. Move the tong and backup assembly on to the tubing joint. Use the lift cylinder to ensure the tong jaws are at the correct location above the connection joint. As the assembly is moved on to the joint the pipe will contact the “kicker bar” on the rear of the backup door, causing the backup door to close. Ensure backup door and tong door are fully closed against the latch posts. Centre the joint roughly midway between the tong and backup jaws - rig personnel are required to stabilize the tong and backup around the connection until the jaws have been clamped shut. Actuate the backup clamping valve (push it toward the centre of the tong) to clamp the backup jaws on to the tubing below the connection point. Note that the backup control is “clamp and release”, meaning that once the backup jaws are clamped, the jaws remain under clamping pressure until the operator manipulates the backup control handle to release pressure 2.H.5: B llustratIon ackup ontrol lamp Begin rotation with the tong in high gear (high speed/low torque). See Section 2.G.3 to properly set the tong to high gear. Do not shift gears while the tong is rotating. SHIFTING TONG WHILE ROTATING THE MOTOR AND CAGE PLATE MAY RESULT IN CATASTROPHIC GEAR TRAIN FAILURE Push the motor control valve toward the tong to rotate the cage plate at high speed in the make-up direction.
Page 37 LW9625 9- ” T & FARR® B & o eTup peRATion Ackup Making A Connection (Continued) As the joint becomes fully made up the increasing torque demand will stall the motor, and displayed torque will increase. m) Stop rotation, and shift to low gear (low speed/high torque - See Section 2.G.3 for shifting to low gear). This will enable the tong to produce adequate torque for making up the joint to specification. Push the rotation control handle all the way in to complete the connection at low speed/high torque. Observe the torque gauge - when the specified make-up torque is reached stop rotation. Reverse the rotation control valve to release the tong jaws from the tubing (see Illustration 2.H.7). 2.H.7: m llustratIon otor ontrol eleasIng When the tong jaws are freed release the backup jaws by pulling the backup clamp control handle away from the tong toward the operator. 2.H.8: B llustratIon ackup ontrol eleasIng 2.23 echnicAL AnuAL ecTion onTenTS...

Ensure hydraulic power supply to the tong and backup is energized. The master link on the rigid sling must be used to suspend the tong. Do not suspend the tong directly from the rigid sling. See Illustration 2.H.1. Set the backing pin on the tong AND backup for “breakout” operation. Lift up on the backing pin and rotate it to the “breakout” position, which is 2 o’clock as seen from the front of the tong. The opening in the rotary gear must be aligned with the tong door opening in order to properly set the backing pin (see Illustration 2.H.10).

LW9625 9- ” T & FARR® B AinTenAnce Ackup McCoy Completions & Drilling recognizes that minor on-site repairs and modifications are required to maintain peak operating condition of your equipment, or to match your equipment with the operating environment. Examples of minor repairs are • replacement of damaged hydraulic hoses and fittings. • replacement of malfunctioning pressure gauges and valves. • replacement of door cylinders • replacement of fasteners Any replaced component must be an identical component supplied by McCoy Completions & Drilling. Replaced fasteners must be Grade 8 or equivalent, or whatever fastener is specified by McCoy. GENERAL MAINTENANCE SAFETY PRACTICES The practices identified here are intended as a guideline. All personnel are responsible for performing their tasks in a manner that ensures worker, equipment, and environmental safety, and may require taking additional steps that are not identified in this section. Equipment maintenance shall be performed only by designated qualified maintenance personnel. Wear approved eyewear and foot- wear, and follow all of your company’s safety guidelines Do not begin a maintenance task without the proper tools or materials on hand, or the proper drawings and documentation necessary. Schedule planned maintenance with operators to avoid conflicts, unnecessary downtime, and the danger of accidental equipment activation. Notify operations when maintenance procedures are complete and equipment functionality is restored. Isolate the location of the maintenance under way to prevent unaware personnel from inadvertently exposing themselves to a hazard. Use tape, rope, or signage to clearly indicate “off-limits” area. Replacement of large, heavy individual parts and/or heavy structural components must be performed using an approved lifting device of sufficient lifting capacity. Use care when attaching the lifting device, and safeguard area to avoid endangering personnel or equip- ment. All spare parts must meet or exceed OEM specifications in order to maintain equipment integrity, especially protective equipment McCoy recommends that disconnection of hydraulic connectors be performed with the power unit off and the hydraulic circuit depres- surized.
Page 44: Lubrication
LW9625 9- ” T & FARR® B Ackup AinTenAnce LUBRICATION Use a quality multipurpose bearing lubricant that will remain within its viscosity range at expected operating temperatures. In addition, Farr recommends the following lubrication procedure at the completion of each job prior to storage. Cage Plate Cam Followers The cage plate cam followers are sealed units, and do not require individual lubrication. However, the cage plate and rotary gear grooves in which the cam followers ride should be lightly greased. When the cage plate is rotated as a unit, the cam fol- lowers are exposed, and can be greased. Continue rotating the cage plate assembly until all cam followers, top and bottom, are greased. 3.D.1: c llustratIon olloWer uBrIcatIon Rotary Idler Bearings Apply grease to these bearings through the grease fittings in the ends of the rotary idler shafts, located on the top of the tong to the inside of each rigid sling weldment (2 locations total). 3.D.2: r llustratIon otary Dler uBrIcatIon ecTion onTenTS echnicAL AnuAL...

If the cage plate turns with the rotary gear, the jaws will not cam properly and, therefore, will not bite on the tubing or casing. Tightening the brake band against the cage plates will increase frictional resistance, allowing jaws to cam properly and grip the casing. Adjust the brake band using the adjustment nut and bolt set as shown in the illustration below. Use caution, as over-tightening will cause excessive wear to the brake bands. rake DJustment rake 3.e.1: B llustratIon rake DJustment...
Page 51: Shifter Detent Force Adjustment
LW9625 9- ” T & FARR® B AinTenAnce Ackup Shifter Detent Force Adjustment: Over time wear to the shifting shaft, wear to the detent ball, and loss of spring tension in the detent spring may result in a loose or “sloppy” fit within the top shifter bushing. The detent pressure may be increased or otherwise adjusted by loosening the 7/16” UNF locking jam nut, and turning the 7/16” UNF detent bolt. Should adequate detent action not be achieved, the shifting shaft, detent ball, or detent spring (or possibly all three) may need to be replaced (see Pp. 5.12 - 5.13). 3.e.2: s llustratIon HIFter etent orce DJustment Safety Door Switch Adjustment The safety door switch should interrupt hydraulic power to the motor when the tong door is opened, or even slightly ajar. This is a critical safety system, and proper adjustment is necessary to maintain the intended function. If the rotary gear does not immediately and completely stop rotating when the door is opened, remove the tong from service and perform the following adjustments: a. Set the tong up in a controlled testing environment without connecting hydraulic power. b. Open the tong door and check operation of the safety door switch plunger. Depress and allow it spring back several times to ensure smooth operation. If the plunger binds or jams, remove the control cable guide mount at the door end, remove the control cable and plunger, and thoroughly clean and lubricate the plunger and control cable before reinstalling. Test the control cable after cleaning and reinstallation. The cable end should spring back when depressed. If the cable does not smoothly spring back, replace the control cable. d. Following reinstallation the plunger should extend 1/4 of an inch from the end of the control cable guide mount.

Begin rotating the cage plate. Open the tong door - the cage plate should immediately and completely stop. Release all controls, and close the tong door again. Ensure the cage plate rotates with the door closed. If cage plate continues to rotate with the door open, adjustment of the position of the plunger on the safety door switch is necessary. Remove hydraulic power from the tong. Loosen the 15/16” valve lock nut securing the cable guide tube, and remove the cable guide tube from the mounting block. Loosen the jam nut locking the position of the push-pull cable inside the cable guide tube. Rotate the cable guide tube one revolution CLOCKWISE, causing the plunger to extend slightly further from the end of the guide tube. NOTE: Only small adjustments are necessary - adjust the mounting tube only one revolution at a time between functional tests of the safety door. Secure the cable guide tube with the jam nut after each adjustment. 3.e.4: s llustratIon aFety DJustment Re-install the push-pull cable guide tube in to the mounting block and secure with the 15/16” valve lock nut. m.

Page 53: Recommended Periodic Checks
LW9625 9- ” T & FARR® B Ackup Safety Door Switch Adjustment (continued); Release all controls, and close the tong door again. Ensure the cage plate rotates with the door closed. If cage plate continues to rotate with the door open, further adjustment of the safety door switch is necessary. Remove hydraulic power from the tong. Repeat steps “h” through “n” as many times as necessary to properly adjust the safety door mechanism. Once the adjust- ments are satisfactorily complete the tong may be returned to service. RECOMMENDED PERIODIC CHECKS Door Stop Springs The springs inside the actuator cylinders must be of sufficient strength to enable the door latch mechanisms to snap closed properly. Door stop spring fatigue will result in sluggish latch operation. Replace the latch springs inside the cylinders when this occurs.
Page 54 LW9625 9- ” T & FARR® B Ackup AinTenAnce OVERHAUL PROCEDURES (CONTINUED): REMOVAL OF TOP PLATE Support the rigid sling with a crane. Remove the two hitch pins from each rigid sling pin, and remove the rid sling pins. The rigid sling may now be lifted away from the tong. Remove both rigid sling hanger bracket weldments - note that the two inside fasteners on each hanger are long bolts that run down through body spacers and are secured on the bottom plate with nylock nuts. 9. Disconnect the hydraulic connections from the motor. Undo the restraints securing the inlet and outlet lines from their sup- ports, and the four 3/8” x 1” bolts securing the valve mount weldment to the top plate. Lift the entire hydraulic valve section away from the tong. Remove the inlet and outlet support pieces. 10. Remove the adjustable outlet support from the top plate. 11. Remove the two tong door spring cylinders. Remove the Z-shaped door cylinder mounting brackets from the top of each door assembly. 12. Remove each door assembly by removing the door pins. Remove the narrow flat washer and thin nylock nut from the bottom of each door pivot shaft. Support each door assembly as the door pin is removed - a soft alloy material (e.g. brass rod, etc.) may be required to lightly tap the shaft up through the door assembly until it comes free at the top. NOTE: If your tong is equipped with the safety door system you may leave the safety door switch components in place on the door assemblies.
Page 55 LW9625 9- ” T & FARR® B AinTenAnce Ackup REMOVAL OF TOP PLATE Continued: 27. Remove the two 3/8” x 6” hex bolts that run down through the remaining body spacers - these are secured on the bottom of the tong with 3/8” nylock nuts. 28. Remove the hex head bolts and recessed socket head cap screws around the perimeter of the tong which secure the top plate to the gear case housing. 29. With all the above steps taken, the top tong plate can be lifted off providing access to the inside of the gear case.

Page 67: Daily Inspection & Maintenance Checklist (Power Tong)
LW9625 9- ” T & FARR® B AinTenAnce Ackup DAILY INSPECTION & MAINTENANCE CHECKLIST (POWER TONG) Farr recommends that the following inspection and maintenance procedures be performed before each use, and at least once per day when the tong is in steady use, in the order in which they are listed. 1. Rotate cage plate/rotary gear until the opening in the rotary gear faces towards the rear of the tong. DO NOT PERFORM ANY FURTHER ACTIONS OR MAINTENANCE WHILE THE TONG IS CON- NECTED TO ANY HYDRAULIC POWER SUPPLY. FARR RECOMMENDS THAT ALL HYDRAULIC LINES ARE FULLY DISCONNECTED, AND RESIDUAL HYDRAULIC PRESSURE IS BLED OFF.
Page 68 LW9625 9- ” T & FARR® B Ackup AinTenAnce Perform a visual inspection of all hydraulic lines. Replace flexible lines if they appear to be cracked, fatigued, or have 13. visible signs of wear from contact with a rigid object. 14. Perform a complete greasing of the tong - refer to Maintenance section of the technical manual Ensure main supply and return connections to the tong are fully made up. Re-connect the remainder of the hydraulic 15. lines, and, if applicable, the electrical line to the turns counter. FAILURE TO ENSURE THAT THE SELF-SEALING SUPPLY AND RETURN LINES ARE FULLY MADE UP MAY RESULT IN CATASTROPHIC EQUIPMENT FAILURE. If using a stand-alone power unit, start it now - refer to the power unit technical manual for startup procedures. Listen to power unit for a moment to see if there are any unusual mechanical sounds (rubbing, grinding, excessive pump noise). If using a diesel unit, allow sufficient time for the engine to reach operating temperature before increasing engine RPM. Once engine is warm, gradually increase engine RPM until operating speed is reached.
Page 69: Monthly Inspection & Maintenance Checklist (Power Tong)
7. Repair or replace any damaged or missing external body parts, such as torque gauge mounts, hydraulic supports, safety door protectors, etc. Perform a visual inspection of all fasteners and protruding body pieces (example: hydraulic valve mounts, inlet & outlet 8. line supports, tong legs, shifter handle pivot lugs). Tighten or replace loose or missing fasteners. Farr recommends that damaged or missing body parts be repaired or replaced as soon as possible. Inspect tong for signs of premature wear, or moving parts that are rubbing (bare metal where there used to be paint is 9. a good indication of wear. Inspect all paint - locations in which the paint has been damaged must be repaired prior to the tong being returned to 10. service. Prepare areas to be painted to ensure they are free of grease, dirt, or solvent. Touch up using a solvent-based acrylic paint - “McCoy Grey” is paint color number RAL7015 (contact Farr sales for paint number for custom paint ap- plications). Allow sufficient time for paint to dry before proceeding. Inspect all external welds. Any weld that is cracked or separating must be repaired and repainted before returning the 11. tong to service. 3.27 echnicAL AnuAL ecTion onTenTS...
Page 70 LW9625 9- ” T & FARR® B Ackup AinTenAnce Perform a visual inspection of all lifting points - if visible damage is seen, including cracks, broken lugs, distorted metal, etc. replace damaged part(s) before placing tong in service. Also inspect all chains, master links, and turn- buckles - again, if any damage is noted replace the damaged part(s) before placing the tong in service. Refer to 12. Section 2A of the technical manual (Sling/Load Bearing Device Safety) for information on recommended testing and recertification. Please note that turnbuckles with part number 101-3086 (short turnbuckles) use a high-strength pin which must be supplied by Farr. “SHORT” TURNBUCKLES HAVING PART NUMBER 101-3086 EMPLOY HIGH-STRENGTH PINS WHICH MUST BE SUPPLIED BY FARR. Rotate the gear train by hand, and use a flashlight to perform a visual inspection of the gear train through the access panel and the opening of the rotary gear while the gear train is being rotated. If gear damage or chips of metal are 13. seen, the tong should be removed from service and overhauled to avoid further damage. Replace access panel when inspection is complete. Inspect all jaws and dies in use for the maintenance interval. Inspect the jaw roller pins for signs of damage - replace 14.

Farr recommends that damaged cylinders be replaced. 29. Rotate tong in low gear for 5 minutes while monitoring pressurized seals and hydraulic lines. If a seal, line, or fitting begins to leak while tong is rotating, it must be replaced before the equipment is returned to service. Rotate tong in high gear for 5 minutes while monitoring temperature of top and bottom bearing caps. If the bearing caps 30. are hot to the touch (higher than approximately 50 C) replace the applicable bearings. Likewise if the tong is making unusual noises check for damaged bearings (see Maintenance Manual for all bearing locations). Install load cell. If using a tension load cell, perform a visual inspection and replace any cracked, broken, or distorted 31. components including links and chains. If using a compression load cell, replace any component that has been crushed or otherwise distorted through compression. If applicable, inspect the load cell anchor pins (tension load cell only). Replace the anchor pins if cracking or metal 32.
Page 72: Daily Inspection & Maintenance Checklist (Backups)
LW9625 9- ” T & FARR® B Ackup AinTenAnce DAILY INSPECTION & MAINTENANCE CHECKLIST (BACKUPS) Farr Canada recommends that the following inspection and maintenance procedures be performed before each use, and at least once per day when the backup is in steady use, in the order in which they are listed. Do not perform any maintenance while the tong and backup assembly is connected to any hydraulic power supply. Farr Canada recommends that all hydraulic lines are fully disconnected, and residual hydraulic pressure is bled off. Ensure adequate containment is in place to prevent environmental contamination from residual hydraulic fluid. nIts 1.

LW9625 9- ” T & FARR® B AinTenAnce Ackup DAILY INSPECTION & MAINTENANCE CHECKLIST (POWER UNIT) Farr recommends that the following inspections and maintenance procedures be performed before each use, and at least once per day when the equipment is in steady use, in the sequence in which they are listed. Rigorous inspection and maintenance, especially lubrication, is essential in order to ensure that your equipment always meets specifications, and to prevent catastrophic failures that can severely damage your equipment and cause worker injury. If using a stand-alone power unit, perform the following inspection and maintenance procedures before each use, and at least once per day when the power unit is in steady use: Do not perform any maintenance while the power unit is energized (electric) or if the engine is running (diesel). Ensure the electrical supply is locked out, or, if using a diesel power supply, ensure that the engine is locked out or the starting mechanism otherwise disabled. Iesel 1. Check engine oil levels - add if necessary 2. Check diesel fuel tank - fill if necessary. 3. Visually inspect all fan belts. Activate mechanical shut-off device - ensure that shut-off switch on engine is engaging when manual shut-off switch 4. is actuated. lectrIc Visually inspect all electrical lines and visible connections. If your unit is NOT explosion proof, open the electrical 1. enclosure and VISUALLY inspect contacts and connections for signs of corrosion or arcing. Do not open explosion- proof enclosures. NEVER PLACE HANDS INSIDE AN ELECTRICAL ENCLOSURE UNLESS YOU HAVE CONFIRMED THAT THE POWER HAS BEEN DISCONNECTED AND LOCKED OUT 2.
Page 74 Inspect all fasteners and fastener safety wires. Replace any missing fasteners - use Grade 8 bolts only. Re-torque all 5. external fasteners to SAE specifications. 6. Inspect backing pin(s). If cracked, broken, or bent it (they) must be replaced. 7. Repair or replace any damaged or missing external body parts, such as torque gauge mounts, hydraulic supports, safety door protectors, etc. Inspect all paint - locations in which the paint has been damaged must be repaired prior to storage. Prepare areas to be 8. painted to ensure they are free of grease, dirt, or solvent. Touch up using a solvent-based acrylic paint - “McCoy Grey” is paint number RAL7015. Allow sufficient time for paint to dry before proceeding. Perform a liberal lubrication of the equipment - refer to Maintenance section of manual to determine lubrication points. 9. Generously fill the gear train housing with grease through the access panel, and also through the opening in the rotary gear. 10. Connect the equipment to a hydraulic power unit. Ensure all lines are fully made up to prevent equipment damage from excessive back pressure. Do not neglect to connect the motor drain. 11. Energize power unit. Rotate tong for one minute, stop, and reverse the direction of rotation for another minute, ending with the opening of 12.
Page 75 LW9625 9- ” T & FARR® B AinTenAnce Ackup Energize power unit. Rotate tong for one minute, stop, and reverse the direction of rotation for another minute, ending 13. with the opening of the rotary gear facing the gear train. 14. De-energize the power unit, and perform a third generous lubrication of the gear train, including the gear housing. 15. Energize power unit, and rotate the tong for a final time, one minute in one direction, stop, and reverse the direction of rotation for another minute, this time ending with the rotary gear in the “open throat” position. Extend all hydraulic cylinders, and inspect cylinder rods for signs of mechanical damage, flaking, or rust. Farr recom- 16. mends that damaged cylinders be replaced prior to storage. If you are using a frame-mounted tool, the tong must be lowered onto the backup in order to remove the risk of sudden and catastrophic movement when pressure is removed from the float cylinders. Cover the top of the backup with pro- tective cloth to protect the paint on the backup. Place two wooden beams across the top of the tong, ensuring that the 17. beams have a minimum size of 4” x 4” x the width of the tong. Cover the tops of the wooden beams with more protective cloth to prevent paint damage to the tong. When lowering the tong onto the beams, ensure that the beams come into flat contact with the bottom of the tong, away from bearing caps, brake bands, or other protrusions on the bottom of the tong. Ensure that the tong hanger chains are loose, but not dangling into contact with the hangers or top plate of the tong. epressurIzatIon roceDure torage Rotate the tong to the “open throat” position. Exercise each hydraulic cylinder several times - open the tong and backup doors (if equipped), retract and extend the remote backing pin ramp (if equipped), retract and extend the float cylinders. Leave all cylinders except for the door cylinders in their fully retracted position. The general idea is to have as little of the chrome cylinder rods exposed as possible. De-energize the power unit. Repeatedly actuate the tong motor control valve lever IN BOTH DIRECTIONS to dissipate any residual pressure in the valve and motor. Remove the hydraulic SUPPLY line from the equipment.
Page 76 LW9625 9- ” T & FARR® B Ackup AinTenAnce If possible, store in a sealed, climate controlled environment. If isolated storage is not available, Farr recommends storing your wrapped equipment in a secure, out-of-the-way location, using silica gel desiccant to reduce the humidity within the wrapping. As a guideline, use 125 g. of desiccant for each cubic metre of space, or 3.5 g. per cubic foot. alculatIon equIreD esIccant Calculate the trapped air volume by measuring the outside dimensions of the tool to be stored, and treat that as the volume to be stored. For example, the external dimensions of a KT20000 20” power tong are 80.25” x 50.5” x 28”, which calculates to an approximate volume of 113500 in , or 66 ft (1.87 m Multiply the calculated air volume, in cubic feet, by the recommended amount of desiccant per cubic foot. Carrying forth the example used in the previous step, the required desiccant charge would be 3.5 g. x 66 ft , equaling 231 g. Several manufactur- ers offer silica gel desiccant in packaged quantities of 125 grams per bag, so two packages of desiccant would be required. Please keep in mind that this is a guideline only - more or less desiccant may be required in extreme environmental conditions. For best corrosion resistance the equipment should be removed from storage and exercised on a regular basis, depending on the storage environment. Farr recommends that for equipment stored in a salt-water maritime or exposed dusty environment, repeat steps 9 through 24 monthly. For equipment stored in isolated storage in a non-maritime environment, repeat steps 9 through 24 quarterly.
Page 77 LW9625 9- ” T & FARR® B AinTenAnce Ackup TUBULAR CONNECTION EQUIPMENT RE-COMMISSIONING PROCEDURE Perform the following recommissioning procedures when removing tubular connection equipment from short or long-term storage back into regular service. These procedures are essential for ensuring proper equipment preparation and operation. The following procedures also assume that the decommissioning and storage procedures recommended by Farr have been strictly observed. Remove all protective plastic wrapping. If there are desiccant packs with the assembly, they may be disposed of with 1. the regular garbage. 2. Remove the access panel on the side of the tong directly adjacent to the shifter mechanism. 3. Wipe excess grease or heavy oil from exposed cylinder rods. If applicable, re-connect chain sling to lifting lugs. Perform a visual inspection of all lifting points - if visible damage is seen, including cracks, broken lugs, distorted metal, etc. replace damaged part(s) before placing tong in service. Also 4.
Page 78 LW9625 9- ” T & FARR® B Ackup AinTenAnce Perform a full functional test of the equipment including, if applicable, backup components and float frame components. 20. Report and correct any hydraulic leaks from the hydraulic valve bank, or from any hydraulic cylinders that are used. If using a frame-mounted tong and backup system, raise the tong off the beams that it is resting upon. Remove the 21. beams and protective cloths - inspect the paint on top of the backup and the bottom of the tong to ensure it has not been damaged by the beam. Test safety door feature (if equipped). Open the tong door(s), and attempt to rotate the cage plate at low speed (low gear) in both directions (makeup and breakout). If cage plate begins rotating, the safety door mechanism is not func- 22. tional, and the tong must be removed from service until the safety door mechanism can be repaired. If the safety door is operating correctly, cage plate rotation will not be inhibited once the door is closed and latched. NEVER OPERATE YOUR EQUIPMENT WITH A BYPASSED OR MALFUNCTIONING SAFETY DOOR While rotating the cage plate, ensure that the jaws properly cam. If the jaws do not cam properly, the brake bands 23. need to be tightened. Incrementally adjust both the top and bottom brake bands EQUALLY until proper cam action is achieved. 24. When all of the previous steps are completed, you may return your re-commissioned equipment to service. 3.36 ecTion onTenTS echnicAL AnuAL...
Page 79: Troubleshooting
TONG WILL NOT DEVELOP SUFFICIENT TORQUE Malfunctioning relief valve on tong hydraulic circuit. POSSIBLE PROBLEM: Relief pressure set too low. SOLUTION: Increase setting. To check, block the oil line beyond the relief valve and determine pressure with a gauge. POSSIBLE PROBLEM: Relief valve is stuck. SOLUTION: Check for contamination of oil that may inhibit the way the valve actuates. Remove valve and clean, ensur- ing that the valve spring operates smoothly. POSSIBLE PROBLEM: Relief valve is leaking. SOLUTION: Check valve seat for scouring. Check oil seals. Check for particles stuck under the valve system. POSSIBLE PROBLEM: Directional valve is leaking. SOLUTION: Check directional valve. Neutral position should return fluid directly to the reservoir. Replace or repair valve to ensure correct operation. POSSIBLE PROBLEM: Power unit is not producing adequate pressure. SOLUTION: Troubleshoot power unit (see user’s manual for your particular unit). POSSIBLE PROBLEM: Poor hydraulic pressure at the tong despite adequate pressure at the power unit, or excessive back pressure in the return line. SOLUTION: Restrictions exist in line between power unit and tong. Inspect integrity of self-sealing couplings to ensure they are allowing full fluid flow. Check to ensure no other restrictions exist (contaminated catch screens or filters, for example). POSSIBLE PROBLEM: Fluid viscosity is not appropriate (too high or too low). SOLUTION: Ensure hydraulic fluid being used is the viscosity recommended by McCoy Drilling & Completions. Power unit pump may not prime if fluid is too heavy, and the hydraulic system will overheat if fluid is too light. Replace with proper viscosity fluid. SOLUTION: Hydraulic fluid viscosity is affected by environmental conditions. Ensure the fluid being used is suitable for high or low temperatures. Replace with proper viscosity fluid for the operating conditions if necessary. POSSIBLE PROBLEM: Worn or damaged tong motor causing slippage. SOLUTION: Replace or repair worn or damaged motor. POSSIBLE PROBLEM: Damaged bearings or gears causing excessive drag. SOLUTION: Replace or repair worn or damaged gears or bearings. POSSIBLE PROBLEM: Jaws slipping on pipe. SOLUTION: Ensure jaw dies are not worn to the point that they cannot grip. Ensure the correct sized jaws are in use. POSSIBLE PROBLEM: Torque gauge is indicating incorrectly SOLUTION: Incorrect gauge is being used. Ensure gauge is the proper range, and has been properly calibrated for the arm length of the equipment in use. SOLUTION: Gauge has been damaged. Check gauge operation and calibration on independent system. echnicAL AnuAL ecTion onTenTS...

Page 84: General Comments
LW9625 9- ” T & FARR® B Ackup RouBLeShooTing GENERAL COMMENTS The following factors generally contribute to poor hydraulic operation and premature wear of equipment: Contaminated hydraulic fluid due to overuse, overheating, or inadequate fluid filtration. Unsuitable hydraulic fluid, especially in extreme climatic conditions. Defective packing or seals in components of the hydraulic system. Poor or incomplete hydraulic system training. Users must be fully qualified to operate the equipment, and have complete understanding of the hydraulic system. If your hydraulic troubleshooting procedures involve flow and pressure tests at the power unit, Farr Canada Corp. recommends construction of a test rig that can easily be connected to the main suction and discharge ports of the power unit. ecTion onTenTS echnicAL AnuAL...

Page 126 LW9625 9- ” T & FARR® B Ackup oRque eASuReMenT TROUBLESHOOTING Under normal operating conditions, and with proper maintenance, the torque gauge and load cell system are designed to give lasting trouble-free performance. Faulty indication on the gauge will very often define a fault within the gauge. IF TROUBLESHOOTING REVEALS THAT THERE IS INSUFFICIENT FLUID IN THE SYSTEM, BEFORE RECHARGING, CHECK THAT ALL SYSTEM COMPONENTS ARE FREE FROM DAMAGE. THIS WILL ENSURE THAT FLUID LOSS WILL NOT CONTINUE AFTER RELOADING Symptom: No indication on gauge. Possible Problem: Obstruction in hydraulic hose.
Page 127 LW9625 9- ” T & FARR® B oRque eASuReMenT Ackup PERIODIC INSPECTION AND MAINTENANCE ONLY QUALIFIED, DESIGNATED PERSONNEL ARE PERMITTED TO PERFORM MAINTENANCE ON THE TORQUE MEASUREMENT SYSTEM. Inspection The torque measurement system supplied with your equipment is designed and built to provide years of trouble-free service with minimum maintenance. Periodic inspections of the load cell, hydraulic lines and fittings are recommended in order to keep the system in top operating condition. A thorough inspection should be made at each rig-up. Fluid Recharge Recharge hydraulic system with W15/16 fluid through the check valve on the torque indicating gauge. Recharging must only be performed when there is no load on the load cell. Refer to the illustrations on pages 6.3 & 6.4 for guidance if required.
Page 128 LW9625 9- ” T & FARR® B Ackup Reference Checking Your Torque Measurement System (continued): Tension Load Cell (continued): Perform a simple calculation to determine the expected indication on the torque gauge based on the known hoisted weight. This is a calculation that must be performed using imperial units (eg., pounds and feet). The calculation is: [KNOWN WEIGHT] x [ARM LENGTH (in feet)]. For example, if the arm length is 36 inches and the hoisted weight is 1000 lbs the calculation is: 1000 x (36/12) = 3000 Therefore, the expected indication on the torque gauge should be 3000 lbs-ft. Repair And Calibration Return the load cell and indicator gauge to the authorized repair facility for repairs and calibration. ecTion onTenTS echnicAL AnuAL...
