On-vehicle Change of main-teeth oil seal
1. Disconnect the drive shaft from the speed reducer:
(a) Mark the assembly mark on the two flanges;
(b) Tear down the four sets of bolt and nut.
2. Tear down the flange and dust cover assembly.
3. Tear down the oil seal.
Tear down the oil seal with SST.
4. Mount on the new oil seal:
(a) Coat the lithium base grease on the lips of oil seal;
(b) Tap in the new oil seal with SST.
Remark: tap the new oil seal until it is in place.
5. Mount the flange and dust cover assembly.
6. Screw up the nut to the specified torque.
Specified torque: (140-160)Nm
7. Rivet the nut.
8. Connect the drive shaft flange with the speed reducer
flange:
Align the assembly mark and connect the flanges with bolts.
Tightening moment(69-79)Nm
9. Check the oil level of the speed reducer.
Change the gear oil where necessary.
Oil brand: heavy-duty oil of grade GL-5
Oil volume: add the oil until it overflows from the oil filler
outlet.
Viscosity: SAE 85W/90 Suspension System and Automobile Axle (Rear) Rear Speed Reducer

Mount of Rear Speed Reducer and
Differential Assembly
1. Mount the speed reducer and differential assembly on
the rear axle housing.
Tightening moment(18-26)Nm
Remark: in case the sealing gasket is mounted, it should be
checked to see whether it is damaged before mounting, if
damaged, change with the new sealing gasket, and the dam-
aged sealing gasket should be clear away; if no sealing gasket
is mounted, no mount is required to mount. Clean the contact
face of the mounted axle housing and coat it with silicon-
rubber plain sealing agent.
2. Connect the drive shaft and flange well and be careful to
align the assembly marks marked when disassembling.
Tightening moment(69-79)Nm
Screw up the oil drain plug with the Tightening moment
of (140-150)Nm
Mount on the half-shaft and the brake assembly to adjust the
brake oil path so that the wheel brake pump is filled with brake
liquid.
3. Inject in the heavy-duty oil.
Oil brand: heavy-duty oil graded GL-5;
Viscosity: SAE 85W/90
Oil volume: add the oil until it overflows from the oil filler
outlets.
Screw up the oil-filling plug.
Tightening moment(140-150)Nm
