  • Page 10: Figure 2 Forward/Reverse Label

    COMPONENT LAYOUT DESCRIPTIONS (See Figure 1, pg 4) AIR INLET The air inlet is a 1" NPT opening with a full-port, Universal (Chicago type) Coupling. The Coupling supplied is the recommended fitting for the GO-A8. Replacing the Coupling with a quick-connect type plug will restrict air flow to the Impactor.
  • Page 11 IN-LINE LUBRICATOR The In-Line Lubricator is a 16 oz, pineapple shaped oil reservoir. Pressure differences between the Lubricator's two chambers forces oil into the airline. Used in conjunction with the high-grade air tool oil provided, the Lubricator ensures the GO-A8 operates properly, and extends the life of the Impactor.

  • Page 12: Figure 3 Locking Pin Label

    OIL CADDY The Oil Caddy is welded to the Opener's Tool Box and is designed to serve a dual purpose. Primarily, the Oil Caddy allows the operator to keep a bottle of air tool oil on-hand at all times; secondly, the Oil Caddy serves as a reminder to check the oil level in the Lubricator.

  • Page 13: Figure 4 Toggle Switch Label

    PIVOT TOGGLE SWITCH The Pivot Toggle Switch is a pneumatic actuated valve that controls the movement of the GO-A8's wheels and Height Adjustment Forks. When the Switch is in the PIVOT position, the wheels will rotate so that they are parallel to the railcar.

  • Page 14: Air Requirements

    V. AIR REQUIREMENTS An Air Compressor of sufficient capacity is needed to provide the necessary air volume (CFM), at the most efficient operating pressure (PSI), to ensure effective and economical operation of the GO-A8 Opener. Low or inadequate air pressure at the opener is costly and wasteful.

  • Page 15: Pre-Start Check List

    VI. PRE-START CHECK LIST Fill the In-Line Lubricator with the air tool oil supplied. See Section VII: Lubrication for details. With air pressure OFF, install Capstan Drive Fitting making sure that the Pin Retainer and O-Ring are properly seated. Check In-Line Lubricator to insure proper oil level. Connect all air hoses and make sure all controls are locked and properly secured.

  • Page 16: Lubrication

    Lubricator. An adjustment valve between the two chambers allows air to enter the upper chamber pressurizing the chamber until the entire Lubricator is at equilibrium. When the GO-A8-PW is operated, air is drawn from the Lubricator. This flow of air drops the pressure in the lower chamber below the pressure in the upper chamber.

    VIII. OPENING CAR GATES Roll the GO-A8 Opener up to the hopper gate until you "rough spot" position the Opener's output drive with the Railcar Gate's Capstan Socket. Using the CAPSTAN SWAGE TOOL (optional accessory, P/N 33-11120), clean-out and square-up the Capstan Socket on the Car Gate so that the CAPSTAN DRIVE FITTING on the Impactor's Output Drive can be aligned properly, and fully seated in the Railcar Gate's Capstan Socket.
  • Page 19 Keep your hands off the Throttle Lever until it is time to start the Opener. Plant feet firmly, and always keep both hands on the handle while operating the GO-A8 Opener. For Railcars with Rolling Capstans, remove the Pivot Locking Pin from the GO-A8's straight position pin hole, and flip the Toggle Switch to the pivot position.
  • Page 20 Once the Car Gate is fully opened, pull the Pivot Locking Pin from the Pivot lock pin hole, and flip the Toggle Switch to the Straight position. This will cause the Tires to rotate perpendicular to the Railcar. Secure the Pivot Locking Pin in the Straight lock pin hole. Roll the GO-A8 Opener back from the Railcar thereby disengaging the CAPSTAN DRIVE FITTING from the Railcar's Capstan Socket.

  • Page 21: Closing Car Gates

    IX. CLOSING CAR GATES Roll the GO-A8 Opener up to the hopper gate until you "rough spot" position the Opener's output drive with the Railcar Gate's Capstan Socket. Re-examine the Capstan Socket. Look for rounded edges, spalling or mushrooming. If needed, re-use the Swage Tool to square-up the Socket. Roll the Opener forward toward the car gate until the CAPSTAN DRIVE FITTING is firmly seated in the railcar's Capstan Socket.
  • Page 22 Release the Throttle Lever the moment the Gate reaches its fully closed position. Prolonged impacting can cause structural damage to the gate mechanism. CAUTION If the Car Gate will not move, STOP using the GO-A8 Opener and notify your supervisor. Do not use other opening devices (pry bars, multipliers, etc.) in an attempt to "Help"...

  • Page 23: Height Adjustment

    X. HEIGHT ADJUSTMENT The height of the Gate Opener’s Drive Shaft can be adjusted to help align the Drive Fitting with the Capstan. By repositioning the wheel axle pins, the Impactor can be raised or lowered up to 4”. To Adjust the height: Pivot the wheels to the Straight position (parallel with wrench).

  • Page 24: Exhaust Diverter

    XI. EXHAUST DIVERTER If you purchased the optional Exhaust Diverter, you can re-direct the exhaust flow backwards toward the GO-A8's tires (instead of forward toward the Gate being opened). See Section XVI for ordering information. To install the Exhaust Diverter: Pivot the Wheels to the Straight position (parallel with wrench).

  • Page 25: Storage

    When not in use the GO-A8 should be stored in a clean, dry & sheltered area, safely out of the way. If a sheltered area is not available and/or not practical, WORKMASTER's water-proof, puncture and tear resistant Protective Cover will provide excellent protection from both the elements and unloading site debris.

  • Page 26: Disassembling The Impactor

    XIII. DISASSEMBLING THE IMPACTOR To service the Impactor, it is necessary to remove the Impactor from the Rolling Cart. The following Instructions cover the complete and correct method of performing this operation: 1. Disconnect air supply from Throttle Valve Body. 2.
  • Page 27 Remove eight [8] Bolts (51) from Hammer Casing (29) and Motor Casing (23). Separate Hammer Casing (29) from Motor Casing (23) and Separator (28). Remove Impact Mechanism (30 to 38) from Hammer Casing (29). Remove Separator (28) from Motor Casing (23). Examine Cone Roller Bearing (70) for damage and/or discoloration.

  • Page 28: Parts Inspection

    XIV. PARTS INSPECTION When the GO-A8 Opener is in for maintenance and the Rolling Cart and Impactor have been disassembled (partial or complete), the components should be cleaned and inspected for wear before lubricating and reassembly of the Opener. Proper maintenance of equipment often depends upon the ability of a service technician to determine whether a part or assembly is worn to the point where it should be replaced.
  • Page 29 The ROTOR (26) is the rotating member of the motor that transmits the torque produced by the Blades. It is machined of heat-treated steel and then ground to precise dimensions. Slots are milled in the body to accept the Blades. The front-end of the Rotor Spindle is splined for driving the HAMMER CAM (31).
  • Page 30 The ROTOR BLADES (27) are the most frequently replaced part since they are subjected to a high degree of movement and friction. The Blades are machined from a fibrous form of laminated phenolic. By means of various treatments, Blades are stabilized so that they can withstand a wide latitude of temperature, humidity, water and oil.
  • Page 31 New Rotor Blades should also be lightly lapped before installing in Rotor to ensure that the Blades will move freely in the rotor slots. It is good practice to replace the Blades each time the Impactor is disassembled for maintenance or IMPORTANT repair.

  • Page 32: Reassembling The Impactor

    XV. REASSEMBLING THE IMPACTOR Once the Impactor's internal components have been inspected, repaired or replaced, the Impactor can be reassembled. The reassembly of the Impactor is essentially the disassembly instructions in reverse order. Refer to Appendix A: Exploded View during reassembly IMPORTANT Wash all parts thoroughly in fresh, clean solvent.
  • Page 33 After the Impactor has been assembled, pour 2 oz. (6-8 squirts) of TOOL- LUBE air tool oil (supplied) in the Air Inlet to ensure immediate lubrication of the complete tool.
