LUBRICANT 5P3975 - Caterpillar

15. Use a micrometer to measure the thickness of the shim pack. Record the measurement for assembly purposes. 16. Remove side gear (9). Identify all parts removed from the side adjacent to the bevel gear before continuing disassembly. Do not mix parts from side to side. 17. Use a hammer and punch to remove three dowel pins (10) from the case housing, as shown. 18. Remove pinion shaft (11) and two pinion shafts (12) from the case housing. 19. Remove four pinion gears (13), four thrust washers (14), and connector (15) from the case housing. 20. Remove side gear (16) from the case housing. 21. Remove shim pack (17) from side gear (16). 22. Measure the shim pack with a micrometer. Record the measurement for assembly purposes. 23. Remove friction spacer (18). 24. Remove disc pack (19). A replacement disc kit consists of five plates (20), four friction discs (21), and one friction spacer (18). Identify all parts removed from the side opposite the bevel gear. Do not mix parts from side to side.Assemble Limited Slip Differential (914G & IT14G)
1. Clean and inspect all parts of the differential. If any of the parts are worn or damaged, use new parts for replacement.2. Replace the disc kits if: a. Either of the end play gap measurements recorded in Step 7 of the disassembly is greater than 0.66 mm (.026 in).b. Disc friction material is worn such that the discs, or areas of the discs, are running steel on steel. Two new shim packs will be needed to properly adjust the end play gap. Each new shim pack consists of two shims 0.46 mm (.018 in), two shims 0.38 mm (.015 in), two shims 0.33 mm (.013 in), and two shims 0.25 mm (.010 in). 3. Use clean axle oil to thoroughly lubricate plates (20), friction discs (21), and friction spacer (18), prior to assembly. 4. Install disc pack (19) in alternate order in the case housing. Start with a plate and end with a plate. 5. Install friction spacer (18) in the case housing with the friction material side down. Apply a small amount of grease to the shims prior to installation. This will retain the shims in place when the gear is installed.6. Install new shim pack (17) of the same thickness from Step 22 of the disassembly on side gear (16). 7. Invert side gear (16) and install in the case housing, as shown. Make certain the shims remain in place while installing side gear (16). Turn side gear (16) slowly until the spline engages with the friction spacer and all five friction discs. Make sure the gear is fully seated. 8. Install connector (15), four pinion gears (13), and four thrust washers (14) in the case housing. 9. Lubricate pinion shafts (11) and (12) with clean axle oil. It is acceptable to use a small amount of force to install the pinion shafts.10. Align the pinion gears and thrust washers with the
