Notice: Transmission remains installed.
 Remove, Disconnect Remove axle shafts (1) - see operation "Axle Shafts, Remove and Install" in group "E". Remove end shield cover (2) - see operation "Gasket for End Shield Cover, Replace". Remove end shield (3) from transmission casing - see operation "Gasket for End Shield, Replace". Remove differential (4) - see operation "Differential, Remove and Install (F 13)". | 
|
 Disassemble Remove seal rings from bearing ring (3) and transmission using KM-454-2 (1) and KM-454-4 (2). Only necessary if bearings are replaced in bearing ring: Remove outer race of tapered roller bearing from bearing ring with KM-304 (4) and KM-451 (5). Place KM-303 (6) underneath. Remove outer race of tapered roller bearing from transmission - use KM-305 and KM-451. With removed transmission, use KM-304 and KM-451. | 
|
Disassemble Only required when replacing: Remove both tapered roller bearing inner races (1) using KM-161-B (2), KM-161-3 (4) and KM-161-4 (3). Notice: Do not interchange outer and inner races respectively when re-using tapered roller bearings. During overhaul operations, the speedometer gear (driving) (5), if still present, must be destroyed.
Disassemble Clamp differential housing in vice with protective jaws. Remove drive gear from differential housing. | 
|
 Important! Only replace drive gears (1) in pairs (driving and driven). Note identification groove (arrows) running around tip of tooth.
Disassemble Only required when replacing: Remove retaining rings (2) from bevel gear shaft. Remove bevel gear shaft. Screw out axle shaft bevel gears and differential bevel gears using KM-458-A. Remove friction washers. | 
|
 Clean Clean all removed parts and transmission housing.
 Inspect Check removed parts for signs of scoring and damage; if necessary replace. Lubricate rotating parts on their bearing, running, seating, and pressure surfaces using transmission fluid.
 Assemble Insert / screw out axle shaft bevel gears and differential bevel gears in differential housing (1). Clamp differential housing with KM-458-A (3) in vice with protective jaws. Centre differential bevel gears using KM-456 (2). Install bevel gear axle (6) and secure with new retaining rings (4 and 5). | 
|
Assemble Attach drive gear (1) with new fastening bolts to vehicle differential housing - tightening torque 70 Nm / 52 lbf. ft. +30 ° to 45 ° . Notice: Only replace drive gears in pairs (driving and driven). Note identification groove (arrows) running around tip of tooth.
Assemble If necessary: Press speedometer gear (driving) onto differential housing with KM-459. Press inner races of tapered roller bearings (3) onto differential housing (4) using KM-453 (2). Install each tapered roller bearing outer race transmission or bearing ring - use KM-304 and KM-451. Slightly fasten tapered roller bearing outer race in housing. | 
|
 Install, Connect Install tapered roller bearing outer race (2) with KM-304 (1) and KM-451 (3) in transmission and/or bearing ring. Drive new axle shaft seal ring into bearing flange with KM-446 - see operation "Axle Shaft Seal Rings, Replace". Install differential (4) - see operation "Differential, Remove and Install (F 13)". Install end shield (3) - see operation "Gasket for End Shield, Replace". Install end shield cover (6) - see operation "Gasket for End Shield Cover, Replace". Install axle shafts - see operation "Axle Shafts, Remove and Install" in group "E". |
