GEAR & BEARING GP-SWING 3789608 - Caterpillar

b. Tighten the center bolt of Tooling (A) to a torque of 27 N m (20 lb ft) to apply 900 kg (2000 lb) of preload on the disc packs. c. Mount the magnetic base of Tooling (B) on Face A of the case housing.d. Zero the dial indicator on Face A, as shown. e. Carefully rotate the magnetic base of Tooling (B) until the dial indicator is touching Face B (the disc pack).f. Record the indicator reading.g. Record two additional indicator readings from different areas of Face B.h. Average the three indicator readings. This is the measured end play gap.i. If the end play gap in Step 4h was greater than 0.81 mm (.032 in), replacement of the existing disc packs is necessary. 5. Remove the disc pack from the case housing. The disc pack consists of two friction discs (5) and two plates (6). 6. Remove actuator housing (7) and gear (8) from case housing as shown. 7. Remove pinion shaft (10) and two pinion gears (9).8. Remove remaining pinion shaft (12) and two pinion gears (11). 9. Remove two pinion gears (9) from pinion shaft (10). Repeat for the remaining pinion shaft (12) and pinion gears (11). 10. Remove gear (13) from the case housing. 11. Remove actuator housing (14) from the case housing by lifting straight upward, as shown. 12. Remove the disc pack from the case housing. The disc pack consists of two friction discs (16) and two plates (15). 13. Remove thrust washer (17).Assemble Limited Slip Differential (918F, IT18F, 924F, IT24F, & 924G)
1. Clean and inspect all parts of the differential. If any of the parts are worn or damaged, use new parts for replacement. 2. Install thrust washer (17) in the case housing. Lubricate the thrust washer face with clean axle oil.3. Replace the disc packs if: a. The stack heights of the disc packs are NOT symmetrical within 0.10 mm (.004 in).b. The disc friction material is worn such that the discs, or areas of the discs, are running steel on steel. 4. When replacement of the disc packs is required, replace with disc packs of the same type. If THIN is marked on the case housing, replace with two new THIN disc packs. If THICK is marked on the case housing, replace with two new THICK disc packs. Do not mix disc packs. Use two THIN or two THICK. Do not use one of each. Use clean axle oil to thoroughly lubricate plates and friction discs, prior to assembly. 5. Install two friction discs (16) and two plates (15) in alternate order in the case housing starting with a plate and ending with a friction disc, as shown. 6. Align the keys of actuator housing (14) with the slots of the case housing and install as shown. 7. Install gear (13) in the case housing. Turn gear slowly until the spline engages with the two friction discs installed in Step 5. Make sure the gear
