Note:   Transmission remains installed.

Overview of Differential

  Remove

1.   Detach axle shafts (1) from transmission Note:   Axle shafts remain in wheel hub. 2.   Remove end shield cover (2) 3.   Remove end shield (3) 4.   Remove differential (4)

5.   Remove 2x axle shaft seal ring from bearing race (3) and transmission •   Remove axle shaft seal ring with KM-454-2 (1) and KM-454-4 (2) 6.   Remove tapered roller bearing outer race from bearing race Note:   Only necessary when replacing the bearing in the bearing race. •   Place tapered roller bearing outer race on KM-303 (6) •   Remove tapered roller bearing outer race with KM-304 (4) and KM-451 (5) 7.   Remove tapered roller bearing outer race from transmission Note:   Only necessary when replacing the bearing in the transmission. •   Remove tapered roller bearing outer race with KM-305 and KM-451 Note:   If the transmission has been removed, use KM-304 and KM-451 .

8.   Detach 2x tapered roller bearing inner race (1) from differential Note:   Only necessary when replacing. Do not interchange outer and inner races respectively when re-using tapered roller bearings. For overhauling work, the speedometer gear (driving) (5) should be destroyed, if still present. On assembling, it is not reinstalled. •   Remove tapered roller bearing inner race with KM-161-B (2), KM-161-3 (4) and KM-161-4 (3) 9.   Remove the ring gear from the differential housing •   Clamp differential housing in vice Note:   Use protective jaws.

10.   Dismantle differential housing •   Detach 2x retaining ring (2) from tapered axle •   Remove tapered axle •   Remove axle shafts and tapered differential gears with KM-458-A •   Remove plastic cage

  Install

Important:   Lubricate rotating parts on their bearing, running, seating, and pressure surfaces using transmission fluid. 13.   Install plastic cage in differential Note:   It must be possible to insert the collar (1) of plastic cage into the guide for the drive pinions in the housing 14.   Assemble differential housing •   Insert drive and differential pinions in differential housing •   Clamp differential housing into vice with KM-458-A (3) Note:   Use protective jaws. •   Centre differential pinions with KM-456 (2) •   Install tapered axle (6) •   Attach 2x new retaining ring (4) and (5)

15.   Attach ring gear (1) Note:   Replace drive gears only in pairs (driving and driven). Note identification groove (arrows) running around tip of tooth. •   Tighten 8x new bolt 40 Nm (+ 30 + 15)°

16.   Attach 2x tapered roller bearing inner race (2) •   Attach tapered roller bearing inner race with KM-453 (1) to differential housing (3)

17.   Attach 2x tapered roller bearing outer race •   Install tapered roller bearing outer races (2) with KM-304 (1) and KM-451 (3) in the transmission and bearing race 18.   Fit axle shaft seal rings •   Install axle shaft seal rings with KM-446 in bearing race and transmission housing 19.   Install differential (4)

20.   Install end shield (2) 21.   Attach end shield cover (1)
