CORE AS-AFTERCOOLER 3268697 - Caterpillar

16. Put the differential in a press as shown. Install Tooling (B) on the end of the differential as shown. Apply pressure on the differential so it can not move in the press. Remove eight bolts (15) and the washers that hold the case and cover together. Slowly release the pressure on the differential until all the spring force under cover (16) is released. 17. Remove cover (16) from the No-Spin differential. Remove bearing cone (17) from the cover. The No-Spin differential is serviced as a unit. However, it can be disassembled for cleaning purposes. 18. Remove side gear (18), spring retainer (19) and spring (20). 19. Remove two drive clutch assemblies (21) and spider assembly (22). Separate the drive clutch assemblies and the spider assembly. 20. Remove spring (20), spring retainer (19) and side gear (18) from the other side of the differential. 21. Remove twelve bolts (25), the washers and nuts that hold ring gear (26) to case (23). Separate the ring gear from the case.22. Remove bearing cone (24) from the case. The following steps are for the assembly of the axle.23. Be sure all parts of the No-Spin differential are thoroughly clean.24. Inspect the splines on the drive clutch assemblies. Remove any burrs or small chips.25. Check the holdout rings (inside drive clutch assemblies) for fractures and chipping or excessive wear of the teeth.26. Check the teeth on the spider and center cam (inside spider assembly) for chips or wear.27. Be sure the center cam moves freely inside the spider assembly.28. Inspect the splines on the side gears. Remove any burrs or small chips. Check the walls for fractures.29. Check the way each side gear fits on the mating axle shaft (part of the wheel end assembly). Be sure the splines do not bind.30. Check the spring load of two springs (20) as follow: a. Place one spring in a spring tester.b. Compress the spring to its operating height of 15.7 mm (.62 in).c. The force of the compressed spring must be 290 31 N (65 7 lb).d. Repeat Steps a through c for the other spring. If either spring load is not correct, both springs must be replaced.31. Check cover (16) and case (23) for wear or score marks. If the parts are worn or scored, use new parts for replacement.32. Check the ring gear and pinion shaft for wear. The ring gear and pinion shaft are a matched set. If either part is worn, a replacement of both parts must be made. Steps 33 through 45 are for the assembly of the differential.
Hot water can cause burns. To prevent possible personal injury, wear protective gloves when handling the hot ring gear in Step 33.
33. Install bearing cone (24) on case (23). Heat ring gear (26) in water to a temperature of 71° to 82°C (160° to 180°F). The ring gear should remain in the water for 10 to 15 minutes so it will be thoroughly heated. Put ring gear (26)
