Always wear eye protection when operating or performing maintenance on this tool. DISASSEMBLY General Instructions 1. Do not disassemble the tool any further than necessary to replace or repair damaged parts. 2. Use extra care not to score, nick or damage surfaces that will contain hydraulic oil under pressure. 3. Whenever grasping a tool in a vise, always use leather–covered or copper–covered vise jaws to protect the surface of the part and help prevent distortion. This is particularly true of threaded members and housings. 4. Do not remove any part that is a press fit in or on an assembly unless the removal of that part is necessary for repairs or replacement. 5. Do not disassemble the hydraulic cylinder assembly unless you have a complete set of seals and o–rings for replacement. 6. Use only British Standard fractional size tools when disassembling these tools. Disassembly of the Tool 1. Push the Link Pin (9) out of the Housing (1) and Side Plates (1 & 2). 2. Lift the Housing from between the Side Plats and separate the two units. Disassembly of the TX-2, TX-4, and TX-8 Cylinder Assemblies 1. Grasp the Housing (1) in copper-covered or leather- covered vise jaws with the inlet end upward and using a .” wrench, unscrew and remove the two Swivel Inlets (18) with their attached Couplers (19). 2. Remove the Housing Assembly from the vise jaws and over a container to catch the oil, move the Piston Rod (2) back and forth several times to purge the hydraulic oil from the Housing. 3. Grasp the Housing in copper-covered or leather- covered vise jaws with the inlet end upward. 4. For TX-2 and TX-4 models, use a hex wrench to unscrew and remove the End Cover Screw (12). Remove the End Cover (14). 5. Push the End Cap (7) inward approximately .” and remove the two Retaining Rings (8) by working them out of the groove in the Cylinder. 6. Install the Seal Insertion Tool (20) on the inlet end of the Housing. The purpose of the Seal Insertion Tool in the following step is to prevent the End Plug Seal from expanding into the Retaining Ring groove. If the Tool is not used, place two thin pieces of flat stock at the midpoint of the opening against opposite walls to control the Seal expansion. 7. Thread one of the Swivel Inlets or a threaded pipe with a tee into the End Cap (7). Use the Inlet or tee as a handle to pull the End Cap and End Plug Seal (15) out of the Housing through the Seal Insertion Tool. 8. Push the Piston Rod toward the inlet end of the Housing and using a hex wrench, unscrew and remove the two Retaining Screws (11). 9. Insert a hooked tool through each screw hole in the Piston Seal Plate (4) and work the Plate upward out of the Housing. 10. Using an o-ring pick, pull the Seal Ring (5) and Piston O-ring (17) off of the Piston Rod. 11. Push the piston end of the Piston Rod forward in the Housing until the Slider Pin (14) aligns with the cross holes in the Housing. 12. Using a small drift, tap the Slider Pin out of the Sliders (5) and position shaft and remove the two Sliders. 13. Push the piston out of the Housing. 14. If the Rod Seal (16) needs replacement, use a hooked tool to pull it out of the Housing. Disassembly of the TX-16 and TX-32 Cylinder Assemblies 1. Grasp the Housing (1) in copper-covered or leather- covered vise jaws with the inlet end upward and using a .” wrench, unscrew and remove the two Swivel Inlets (18) with their attached Couplers (19). 2. Remove the housing assembly from the vise jaws and over a container to catch the oil, move the Piston Rod Assembly (2 & 3) back and forth several times to purge the hydraulic oil from the Housing. 3. Grasp the Housing in copper-covered or leather- covered vise jaws with the inlet end upward. 4. Insert the pins of the End Plug Wrench (21) into the holes of the End Cap (7). Using a wrench on the hex of the End Plug Wrench, unscrew and remove the End Cap with the End Plug Seal (15). 5. Push the Piston Rod far enough into the Housing to expose the hex on the piston head. NOTICE During removal and after the piston shaft is removed, DO NOT grasp the round portion of the shaft with any holding device that will damage the surface. Any nicks or scratches to the surface will allow hydraulic oil to leak from the Cylinder when the tool is reassembled. 6. Sprag the flat end of the piston shaft against rotation and using a socket on the hex of the piston head, -10 unscrew and remove the piston head from the shaft with the Piston O-ring (17). 7. Pull the Piston shaft out of the Housing. 8. If the Sliders (5) must be replaced, position the Slider Pin (14) over a clearance opening in a soft block and use a small drift to tap the Pin out of the Sliders and shaft. 9. If the Rod Seal (16) needs replacement, use a hooked tool to pull it out of the Housing. Disassembly of the Ratchet Link 1. Lay the Ratchet Link flat on a workbench with the Left Side Plate (1) downward and using a hex wrench, unscrew and remove the two Lower Spacer Screws (16). 2. Using a hex wrench, unscr...
