Usage:
NOTE: Check the condition of all O-ring seals and of all parts. If any components are worn or damaged, use new parts for replacement.
1. Be sure that the bores in the tilt cylinder, loader frame and tilt lever are clean and free of dirt and debris. Put 5P-0960 Molybdenum Grease in all pin bores before assembly. Put 5P-3931 Anti-Seize Compound on the inside and outside diameters of all collets before assembly.
2. Attach a hoist and a suitable lifting sling to tilt cylinder (6). Put the tilt cylinder in position in the loader frame, as shown. The weight of the tilt cylinder is 430 kg (948 lb).
3. Attach a hoist and a suitable lifting sling to tilt cylinder pin (18). Align the bores of the loader frame and the tilt cylinder. Install the pin and the shim(s) (if required) in the head end of the tilt cylinder. The weight of the tilt cylinder pin is 24 kg (53 lb).
4. Install collet 917) on each side of the tilt cylinder pin.
5. Put 5P-3931 Anti-Seize Compound on the threads of bolt (16). Install bolt (16), the nut and the washers in the tilt cylinder pin assembly.
NOTE: The collet on one side must not extend farther than the other collet when the bolt and nut are tight.
6. Tighten the bolt and the nut that hold the collets to the tilt cylinder pin as follows:
a. Tighten bolt (16) and the nut evenly to a torque of 1800 ± 200 N·m (1330 ± 150 lb ft). After the bolt and the nut are tight, hit the collets on each side with a heavy hammer until the torque on the bolt and the nut is less than 950 N·m (700 lb ft).
b. Tighten bolt (16) and the nut again to a torque of 1800 ± 200 N·m (1330 ± 150 lb ft). Hit each collet again until the torque for the bolt and the nut is less than 1600 N·m (1180 lb ft).
c. Tighten bolt (16) and the nut to a final torque of 1800 ± 200 N·m (1330 ± 150 lb ft).
NOTE: At the end of 50 service hours, tighten the bolt and the nut that hold the collets to the tilt cylinder pin as in Steps 6a through 6c.
7. Put tube assembly (14) in position on the lift cylinder, as shown. Install four bolts (15) and the washers that hold tube assembly (14) to the lift cylinder.
8. Install two bolts (13) and the washers that hold tube assembly (14) to the lower tube assembly.
9. Repeat Steps (7) and (8) for the other lift cylinder.
10. Connect hose assemblies (11) and (12) to tilt cylinder (6).
11. Move tilt cylinder (6) to the position shown. Secure the tilt cylinder to the rear frame, as shown.
12. Attach a hoist and suitable lifting chains to bucket (9), as shown.
13. Start the engine.
14. While supporting bucket (9) with the hoist, raise the lift arm assembly until the bucket control group safety pins (10) can be removed. Refer to Disassembly and Assembly, "Bucket Control Group Safety Pins - Remove and Install" for the machine that is being serviced. Lower the lift arm assembly and the hoist until the bucket is on the ground. The weight of the bucket is 3955 kg (8720 lb).
15. Attach a hoist and a suitable lifting sling to tilt cylinder (6). Move the tilt cylinder to the position shown. Align the bores of the rod end of the tilt cylinder and the tilt lever.
16. Stop the engine.
17. Attach a hoist and a suitable lifting sling to tilt cylinder pin (8). Install the pin and the shim(s) (if required) in the rod end of the tilt cylinder. The weight of the tilt cylinder pin is 24 kg (52 lb).
18. Install collets (7) on each side of the tilt cylinder pin.
19. Put 5P-3931 Anti-Seize Compound on the threads of bolt (5). Install bolt (5), the nut and the washers in the tilt cylinder pin assembly.
NOTE: The collet on one side must not extend farther than the other collet when the bolt and nut are tight.
20. Tighten the bolt and the nut that hold the collets to the tilt cylinder pin as follows:
a. Tighten bolt (5) and the nut evenly to a torque of 1800 ± 200 N·m (1330 ± 150 lb ft). After the bolt and the nut are tight, hit the collets on each side with a heavy hammer until the torque on the bolt and the nut is less than 950 N·m (700 lb ft).
b. Tighten bolt (5) and the nut again to a torque of 1800 ± 200 N·m (1330 ± 150 lb ft). Hit each collet again until the torque for the bolt and the nut is less than 1600 N·m (1180 lb ft).
c. Tighten bolt (5) and the nut to a final torque of 1800 ± 200 N·m (1330 ± 150 lb ft).
NOTE: At the end of 50 service hours, tighten the bolt and the nut that hold the collets to the tilt cylinder pin as in Steps 20a through 20c.
21. Connect lubrication hose assembly (4) (if equipped) to the rod end of the tilt cylinder.
22. Attach a hoist and a suitable lifting sling to tilt cylinder guard (3). Put the guard in position on the tilt cylinder, as shown. Install the four bolts and the washers that hold tilt cylinder guard (3) to the tilt cylinder. The weight of the tilt cylinder guard is 30 kg (66 lb).
23. Connect lubrication hose assembly (2) (if equipped) to the head end of the tilt cylinder.
24. Put cover (1) in position on the loader frame, as shown. Install the two bolts and the washers that hold cover (1) to the loader frame.
