Usage:
NOTE: Check the condition of all parts. If any components are worn or damaged, use new parts for replacement.
1. Be sure that the pin bores in the bucket, lift arm assembly and tilt link are clean and free of dirt and debris. Lubricate the bores and the pins with 5P-0960 Molybdenum Grease prior to installation. Put 5P-3931 Anti-Seize Compound on the inside and outside diameters of all collets before assembly.
2. Put inside collets (7) in position on each side of the bucket.
3. Attach a hoist and suitable lifting chains to bucket (5), as shown. Put the bucket in position on the lift arm assembly. Align the pin bores in the bucket with the pin bores in the lift arm assembly. The weight of the bucket is 3955 kg (8720 lb).
4. Install shim(s) (9) (if required) between the bucket and the lift arm assembly.
5. Install lower bucket pin (8) in the lower bucket bores on each side of the bucket.
6. Install outside collets (7) on each side of the bucket.
7. Put 5P-3931 Anti-Seize Compound on the threads of bolt (6). Install bolt (6), the nut and the washers in the lower bucket pin assembly, on each side of the bucket.
NOTE: The collet on one side must not extend farther than the other collet when the bolt and nut are tight.
8. Tighten the bolt and the nut that hold the inside and outside collets to the lower bucket pin on each side of the bucket as follows:
a. Tighten bolt (6) 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 collet 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 (6) 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 (6) 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 lower bucket pins as in Steps 8a through 8c.
9. Attach a hoist and a suitable lifting sling to tilt link (3), as shown. Align the bores of the bucket and the tilt link. Attach a hoist and a suitable lifting sling to tilt link pin (4). Install the pin and the shim(s) (if required). The weight of the tilt link pin is 24 kg (53 lb).
10. Install collets (2) on each side of the tilt link pin assembly.
11. Put 5P-3931 Anti-Seize Compound on the threads of bolt (1). Install bolt (1), the washers and the nut in the tilt link pin assembly.
NOTE: The collet on one side must not extend farther than the other collet when the bolt and nut are tight.
12. Tighten the bolt and the nut that hold the collets to the tilt link pin as follows:
a. Tighten bolt (1) 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 collet on each side with a heavy hammer until the torque on the bolt is less than 950 N·m (700 lb ft).
b. Tighten bolt (1) 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 (1) 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 bucket end of the tilt link pin assembly as in Steps 12a through 12c.
13. Lubricate the mounting pins. Refer to Operation and Maintenance Manual for the machine that is being serviced.
End By:
a. Remove the steering frame lock pin. Refer to Disassembly and Assembly, "Steering Frame Lock Pin - Remove and Install" for the machine that is being serviced.
