TORQUE CONVERTER GP 1T1736 - Caterpillar

1. Remove bolt (1) and the washer from the lift cylinder rod end collet assembly. 2. Use tooling (A) to remove outside collet assembly (2). Tighten the forcing bolts evenly and remove the collet. 3. Use tooling (B) to remove inside collet assembly (3). Tighten the forcing bolts evenly and remove the collet. 4. Support the rod end of the lift cylinder and remove pin (4).5. Start the engine. Retract the lift cylinder.6. Release the hydraulic system pressure. Refer to Release the Hydraulic System Pressure in this module. 7. Attach a suitable lifting strap and hoist to the lift cylinder as shown. 8. Disconnect hose assemblies (5) and (6) from the lift cylinder. 9. Disconnect lubrication line (7) (obscured) from the head end of the lift cylinder.10. Remove bolt (8) and the washer from the collet assemblies in the head end of the lift cylinder. 11. Use tooling (A) to remove the collet assembly. Tighten the forcing bolts evenly and remove the collet. Repeat for the inside side collet assembly. 12. Remove pin (9) from the head end of the lift cylinder.13. Remove the lift cylinder from the machine. The weight of the lift cylinder is 150 kg (331 lb).14. Repeat Steps 1 through 13 for the other lift cylinder.Install Lift Cylinders
1. Attach a suitable lifting strap and hoist to the lift cylinder as shown.2. Put the lift cylinder in position in the front frame. The weight of the lift cylinder is 150 kg (331 lb). 3. Align the bores of the lift cylinder and the front frame. Put 5P-0960 Lubricant in the pin bore and install pin (1) in the head end of the lift cylinder. 4. Put 5P-3931 Anti-Seize Compound on the outside and inside diameters of all collets before assembly. Install collet assemblies (2).5. Put 5P-3931 Anti-Seize Compound on the thread of the bolt that holds the collet assemblies to the pin assembly. Install bolt (3) and washer in the collet assemblies. The collet on one side must not extend farther than the other collet when the bolt is tight.6. Tighten the bolt that holds the collet assemblies to the pin assembly as follows: a. Tighten bolt (3) to a torque of 870 110 N m (640 80 lb ft). After the bolt is tight, hit the collet on each side with a heavy hammer until the torque on the bolt is less than 475 N m (350 lb ft).b. Tighten bolt (3) again to a torque of 870 110 N m (640 80 lb ft). Hit each collet again until the torque for the bolt is less than 675 N m (500 lb ft).c. Tighten the bolt to a final torque of 870 110 N m (640 80 lb ft). At the end of 50 service hours, tighten the bolt that holds the collet assemblies to the pin assembly as in Steps 6a through 6c.7. Connect lubrication hose assembly (4) (obscured) to the head end of the lift
