11. Mount the new inner oil seal of rear wheel bearing.
Coat the hyperbolic gear oil on the axle housing where matches
with the oil seal; and plaster the moderate lithium base grease
on the lip open of the oil seal, then put them on the pressure
head and press them in.
Mount of Rear Axle Shaft
1. Press the rear brake and the bearing seat assembly on
the haft shaft.
2. Press the heated inner oil seal seat of rear wheel bearing
on he half shaft;
Notice: the face at the chamfering end of inner oil seal of
rear bearing should contact the oil seal closely, do not
mount it at the incorrect position.
Requirement for heat mount: heat the inner oil seal seat into the
22# oil (GB443-1989) to 100
, after the part is heated
completely, take it out for mount.
3. Mount on the flat steel retaining ring with the ring calipers.
4. Encase the half-shaft rear brake in the axle housing,
screw on the self-locking nut.
