Damage to the tool will □ result! □ Apply final pressure. □ Loosen nut with the spanner ring and pin wrench. □ Move to next stud in pattern 4.0 General Preparations Read and understand all instructions before installing and tensioning studs. This equipment produces very high hydraulic pressures and very high forces. Operators must exercise caution, wear safety glasses and hard hats when using this equipment. High‐pressure fluid from the Hydraulic Pressure Kit system pressurizes the tensioner which generates a stretching force that actually stretches the stud. As the stud is stretched the nut lifts off the flange. The nut is then reseated into position on the flange by turning a nut driver by hand. When the nut is tight against the flange, the pressure in the tensioner is released leaving the stud loaded to its predetermined value. 4.1 Machine Preparation The flange to be tensioned must be fully closed prior to positioning the studs in the flanges. There must be provisions for turning the shafts of the turbine, coupling, gearbox and generator. Also, it will be advantageous to remove as many obstructions as possible from the flange area, ...

Instruction Manual IM-150 AP‐0532 Air‐Operated Hydraulic Pump (reference GE 359B2502) 5.0 Preparation of Hardware 5.1 Nut Preparation For new installations the nuts should come sealed from the factory and will need no cleaning. Previously installed nuts require cleaning as follows: Wire brush using a petroleum based solvent to remove any foreign material on the external surfaces and threads. If previous installation employed a thread locking compound, which will be visible as a grayish‐ green residue, remove as much of this compound as possible. Do not apply thread lubricants to the threads. Finish the cleaning process by rinsing in a volatile solvent such as acetone and allow to dry. 5.2 Stud Preparation Check the stud for any visible damage. If there is any visible damage, do not use the stud and contact the Riverhawk Company for a replacement stud. Please be prepared to supply the turbine number, weight certification, and digital photographs for evaluation. The conical threads of each stud must be clean before installation or removal. This ensures the proper seating of the puller screw. 5.2.1 Stud Cleaning ‐ New Installations For new installations, the studs should come sealed from the factory and will need no cleaning. 5.2.2 Stud Cleaning ‐ Old Installations ...

Instruction Manual IM-150 1. Blow out the threads with compressed air to remove loose debris and dry conical threads. Do not apply a solvent or other cleaning solution to the threads as this may chemically attack the stud. 2. Use Stud Cleaning Kit, GT‐4354 or a similar 1/2" diameter Brass power brush. Picture of Brass Power Brush 3. Insert the brush into an electric drill and set drill to run in a counterclockwise direction at high speed. 4. Work the drill in a circular motion while moving the brush in and out to clean all of the threads. Try not to hold the brush in one place too long, so as not to remove the stud's protective coating. 5. Blow out the threads with compressed air to remove loosened debris. 6. Visually inspect threads for cleanliness. Threads should be bright and shiny. 7. Repeat if any dirt can be seen in the threads. 8. Inspect threads for any damage that may have been caused by previous installation. Do not apply thread lubricants to the threads. Finish the cleaning process by rinsing in a volatile solvent such as acetone and allow to dry. ...
Instruction Manual IM-150 Record each measurement on the supplied charts. Do not allow the measuring instruments to set in the sun 6.0 Stud and Nut Assembly Refer to the Hardware Assembly Drawing (HF‐ ) listed in Section 2.0 of this manual. 1. Assemble the cylindrical nut to the tapered thread end (Pull End) of the stud. 2. Slide the stud and cylindrical nut assembly into the flange as shown in Figures 1, 2 & 3 and install the other nut on the backside. 3. Adjust nut/stud assembly so that the stud protrudes from the face of the cylindrical nut the amount depicted on the hardware drawing (HF‐). SETTING THIS PROTRUSION OF STUD TO NUT IS CRITICAL FOR PROPER TENSIONER OPERATION. 4. Hand tighten the assembly to a snug fit. 7.0 Assembly of Hydraulic Tensioner Equipment 7.1 Kit Assembly Assemble the hydraulic pump with its hose to the puller tool and bleed the system of air per following instructions. 7.1.1 Fittings Make sure both male and female parts are clean and free of debris, see Figure 4 for fitting configuration. Hold female part securely when tightening so as to prevent damage to the adjacent tubing. If the fitting leaks first try retightening as needed. If leaking continues then disassemble and check for scratches or debris on the seating conical surfaces. Clean as required. Replace plastic protective caps when finished with the tooling. ...
Instruction Manual IM-150 7.3 Bleeding Hydraulic System Follow the tensioner assembly instructions of Section 8.0. TO AVOID FAILURE, ENSURE SAFETY AND PROPER OPERATION THE TENSIONER ASSEMBLY MUST BE MOUNTED ON THE STUD BEFORE BLEEDING THE SYSTEM AND TENSIONING BEGINS. Mount tensioner on a stud per the assembly instructions of Section 8.0. Make sure the pump is situated below the tensioner assembly. The tensioner assembly has two ports, one for pressurizing and one for bleeding the system. These ports service a common chamber and therefore may be treated interchangeability. The bleed port must always be oriented in the uppermost position. The puller tool is shipped with a 5/8 in. [16 mm] hex coned stem bleeder fitting installed. With this fitting loosened stroke the pump repeatedly until the stream of oil exiting the tool is free of air then retighten the fitting. Note: The hose is stiff, use of this tooling can be simplified by temporarily mounting the puller tool on one stud prior to final tightening of fittings. This will reduce the tendency for the fittings to loosen during use. 8.0 Assembly of Tensioner on Stud Two types of Tensioner Kits will be encountered in the field. The two assemblies are depicted in Figures 5 & 6. Clean puller screw and check for any debris and dents. Puller screw should be free to rotate and move back and forth. Inspect tensioner guard for any signs of damage. Bent guards should be replaced. All tensioning (pulling) will be performed from the tapered thread end of the stud with orientation of the stud to the flange as shown in Figures 1, 2, & 3. 8.1 Assembly of Tensioner Kit with Integral Safety Cage. Refer to Tensioner Assembly drawing and Figure 5 for tensioner to flange mounting. This ...

Instruction Manual IM-150 The puller screw is a 2‐piece design, This requires that the operator tighten the puller screw into the stud and then install a puller nut. Assembly sequence is as follows: 1. Open the hydraulic return valve on the pump to allow hydraulic fluid to be pushed back from the puller tool into the pump reservoir. (This is automatic with the air‐operated hydraulic pump) 2. Place the spanner ring on the puller side cylindrical nut. 3. Apply a light coat of clean turbine oil or a spray lubricant to the puller screw. Do not use “Never Seize” on the conical threads. 4. Place and hold the puller tool over the end to be tightened. 5. Insert the puller screw through the puller tool into the tapered thread of the stud and tighten. 6. Be sure not to cross‐thread the assembly. 7. Tighten the puller screw using Allen wrenches on the puller screw and the stud. DO NOT wrench on the Hex nut opposite the puller tool. 8. Install the puller nut until it seats snugly on the piston and then back‐off 2 flats. This is particularly important for removal because the stud shortens during disassembly and the tensioner may then bind. 9. At this point the Tensioner Assembly MUST BE FREE TO ROTATE, the puller screw is tight in the stud and the puller nut has been backed‐off the 2 flats. Note: If the tool is not free to rotate it is most likely that the nuts must be repositioned so that the stud may be shifted slightly to the puller tool side of the flange. This can be accomplished as follows ...
Instruction Manual IM-150 CAUTION Personal injury and equipment damage can occur if the puller screw is not securely engaged with the tapered threads of the stud. Proper engagement is achieved when the puller screw is tight in the stud and the tensioner assembly is free to turn. 9.0 Stud Pulling and Tensioning The studs will be tensioned in two steps, at approximately 50% pressure and at final pressure. Follow the tensioning sequence for each flange joint as defined on the data sheets found at the end of this manual. Note: Before threading the puller screw into the stud, carefully check the cleanliness of both the stud's and the puller screw's conical threads. Apply a light coat of clean turbine oil or a spray lubricant to the puller screw. Do not use “Never Seize” on the conical threads. This procedure will ease assembly and assure positive mating of the threads before tightening. WARNING The safety cage MUST be in place and hands kept out of designated areas at all times when the puller tool is pressurized otherwise personal injury can occur. 9.1 Tensioning at 50% pressure After the tensioner is properly installed apply hydraulic pressure to the tool. Bring the pressure to the 50% level in accordance with the following table.

If the steps listed here do not solve your problem, contact the Riverhawk Company thru our website, email, or phone call. Q: A tensioner has pulled itself out of the stud's conical threads.Can I continue using a tensioner on this stud? A: No. Both the tensioner and the stud may have been damaged. If the stud is tensioned, a Nut Buster repair kit, from Riverhawk, must be used to remove the damaged stud by drilling out the nut. Riverhawk can supply a replacement stud and nut based on the initial weight certification supplied with the hardware set (see section 4.2). The damaged tensioner should also be returned to Riverhawk for inspection and repair. Q: The hydraulic tensioner has been taken up to its final pressure. The final stretch length is short of the final stretch target. What is the next step? A: ...
Page 18
Instruction Manual IM-150 Q: Is there an easier way to support or move the tensioner around the coupling shaft? A: Use two straps. One around the coupling shaft and the other attach to any overhead support. Straps must be slack during mounting tensioner to stud and during tensioning. Q: The tensioner is at its final pressure, but the nut cannot be loosen. A: If the nuts cannot be loosened at the final pressure, continually increasing the pressure will not help and can be dangerous and in some cases make it harder to remove the nut. Check the nut to see if its set screws have been loosened. Check for and remove any corrosion around the nut's threads. Q: How do I clean the conical threads on a stud? A: The conical threads are best cleaned using a spiral wound brass brush in a drill as described in section 5.2.2 Q: During the initial steps of removing a tensioned stud, the stick‐out length is found to be wrong. A: Do not proceed. Contact Riverhawk for assistance. With the wrong stick‐out length, the hydraulic tensioner has a limited stroke and may not work properly and can be damaged. ...
