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, unscrew and remove the two Upper Spacer Screws (15). 3. For Series TX-16 and TX-32, use a roll pin punch to tap the Spacer Roll Pin (19) out of the Right Side Plate (2). 4. While applying thumb pressure to the edge of the Ratchet (6), carefully lift the Side Plate off the Assembly. 5. Grasp the Ratchet and Drive Plate (3) and, while maintaining their relationship, lift them both off the Left Side Plate. NOTICE In the following step, when the Ratchet is removed from the Drive Plate, the Drive Segment and Segment Spring will be free to fall from the Drive Plate recess. Do not allow the Drive Segment to fall on a hard surface that might chip the teeth. 6. Push the Ratchet out of the Drive Plate and Remove the Drive Segment (7) and the Segment Spring (14) from the Drive Plate Recess. 7. If the Drive Pin (4) or Drive Pin Spring (5) must be replaced, use a roll pin punch to push the Drive Pin Spring Roll Pin (18) out of the Drive Plate. Once the Pin Spring is removed, the Drive Pin (4) will drop down to the large opening at the bottom of the slot for easy removal. 8. Lift the Lower Spacer (10) off the Lower Spacer Pins (11). If the Pins must be replaced, use a hex wrench to remove the two Lower Spacer Screws from the Right Side Plate. Pull the Pins out of the holes on the inner face of the Right Side Plate. 9. For Series TX-2, TX-4, and TX-8, unscrew the two Spacer Screws and remove the Middle Spacer (9) from the Right Side Plate. For Series TX-16 and TX-32, use a roll pin punch to remove the Spacer Roll Pin (19) from the Right Side Plate. Unscrew the two Spacer Screws and remove the Middle Spacer (9) and Upper Spacer (8) from the Right Side Plate. 10. If the Side Plate Sleeves (12) must be replaced, press the Sleeves out toward the inner face of the Side Plate. ASSEMBLY General Instructions 1. Use extra care not to score, nick or damage surfaces that will contain hydraulic oil under pressure. 2. 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 if threaded members and housings. 3. Apply o-ring lubricant to all o-rings before final assembly. Assembly of the Ratchet Link 1.If the Side Plate Sleeves (12) were removed, press new sleeves, shoulder end trailing, into the Right and Left Side Plates (1 & 2) from the inner face of the side Plates. Make certain the Sleeves are square with the side plate faces and the shoulder of the Sleeves enters the recesses in the Side Plates and are pressed flush with the faces. 2.For Series TX-2, TX-4, and TX-8, position the Middle Spacer (9) against the inside face of the Right Side Plate Apply a non-permanent thread-locking compound to the threads of the two Upper Spacer Screws (15) and secure the Spacer with the Screws through the Side Plate. For Series TX-16 and TX-32, press the Spacer Roll Pin (19) into the Right Side Plate with one end of the Pin flush with the external face of the Side Plate. Insert the tab of the Upper Spacer (8) into the slot in the Middle Spacer (9), and after aligning the holes in both pieces, install them on the Spacer Roll Pin (19). When they are correctly positioned, apply a non-permanent thread-locking compound to the threads of the two Upper Spacer Screws (15) and secure the Spacers with the Screws through the side plate. 3.Insert the two Lower Spacer Pins (11) into the holes in the lower edge of the Right Side Plate. Apply a nonpermanent thread-locking compound to the threads of the Lower Spacer Screws (16) and secure the Pins with the Screws through the Side Plate. 4.Place the Lower Spacer (10) over the Pins against the Side Plate. Make certain it is correctly oriented so that no part of the Spacer extends beyond the edge of the Side Plate. 5.Insert the Drive Pin (4) into the small cross-hole and slot in the Drive Plate (3). Invert the Plate causing the ends of the Pin to enter the slot and move the Pin to the narrow end. 6.Position the Drive Pin Spring (5) in the drive plate slot with the two non-connected ends between the Drive Pin and the large hole in the slot. Position the closed end of the Sp...
