9. Mount on the differential bearing cover:
(a) Align the assembly marks on differential bearing cover
and the speed reducer housing, and press down the
differential bearing by hand.
(b) Mount on the double-eared stop washer and the hex nut.
10. Adjust the clearance between the driving bevel gear and
the axle driven bevel gear
(a) Screw up the hex nuts connecting the differential bearing
cover to the specified torque.
Tightening moment
(80-110)N
m
(b) Attach the measuring meter seat on the face of speed
reducer housing with the measuring head touching the
teeth face, run the axle driven bevel gear with hand to
measure the teeth engagement clearance, and then com-
pare it with the clearance value in step (d) to decide the
order of the adjusting ring tightening according to the
values.
(c) Adjust and screw up the adjusting rings with SST.
Tightening moment
(115-135)N
m
(d) Check the engagement clearance again until the clear-
ance value of the three spots evenly locates on the
circumference of axle driven bevel gear. Otherwise,
adjusting ring adjustment is suggested.
Engagement clearance
(0.13-0.25)mm

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)N

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)N

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.

1. Tear down the speed reducer and the differential
assembly.
2. Tear down the differential from the speed reducer and
differential assembly.

(b) Tear down the planetary gear shaft, the planetary gear,
planetary gear stop gasket, half-shaft gear and half axle
gear thrust gasket.

2. Assembly of Differential
(a) Put the half-axle gear thrust gasket on the half-axle gear
and then encase them in the differential housing.
(b) Encase the planetary gear stop gasket, planetary gear and
encase the planetary gear shaft.
(c) Check the clearance between the half-axle gear thrust
gasket and the differential housing.
Remark: the half-axle gear and the planetary gear should run
freely without stagnant, push the planetary gear inside, then
measure the clearance between the half-axle gear thrust gasket
and the differential housing with dial indicating lamp.
Reasonable clearance range: (0.45-0.75)mm.
Remark: if the clearance value fails to fall within the above
range, change the half axle gear thrust gasket, at the same time,
ensure the left and right half axle gear thrust gasket are same
in thickness.
(d) Tap the pin in the pinhole, and rivet the end of the pinhole
so as to prevent from the pin missing.
Mount of Differential
1. Encase the differential assembly in the speed reducer
housing.
2. Mount the speed reducer and differential.
