Great Wall Hover. Manual — part 62
3. Replace the small bearing of drive bevel gear.
a. Use the brass rod and hand hammer to knock down the small
bearing outer race of drive bevel gear.
b. Use the special tools to press in the new bearing outer race.
c. Replace it by the new bearing inner race when installs the
small bearing..
4
Remove two side bearing inner races from the
differential housing.
a
Use the special tools to remove the side bearing inner race on
the side of differential assembly with bolt.
b. It should pay attention to does not damage the driven bevel
gear when use the vice for clamping to remove the bearing
inner race on another side.
5. Use the wrench to remove the bolt fastened the
driven bevel gear
Caution: It should make the assembly mark on the
driven bevel gear and differential housing before
disassembly.
6
Disassembly of differential assembly
a. Use the hand hammer and special tools to knock out the pin
after remove the driven bevel gear.

b. Knock out the planetary gear shaft, rotate the half axle gear to
take out the planetary gear, then take out the half axle gear
and thrust plate.
7. Assembly of differential assembly.
a. Wash the differential housing.
b. Cover the half axle gear thrust plate with the half axle gear,
then installs it in the differential housing.
c. Rotate the half axle gear; install the planetary gear in rolling
and insert the planetary gear shaft.
d. Use the special tools to hit the pin to fix the planetary gear
shaft, and rivet the inserted hole to prevent the loose of pin.
Remarks: The rotation of half axle gear and planetary gear
should be smooth and without block; push the planetary gear
to inside, then use the dial indicator to measure the clearance
between the half axle gear thrust plate and differential
housing.
Rational clearance range: 0.4-0.75mm
It is necessary to replace the half axle gear thrust plate if the
clearance is beyond the previous range, at the same time ensure the
thrust plate in left and right side has the same thickness.
e. Check the clearance between the half axle gear thrust plate and
differential housing.

f. Clean the surface of differential housing; use the brass rod to
install the driven bevel gear on the differential housing.
Caution: It should align the marked assembly mark when
install the driven bevel gear and knock it in uniformly in
circumference ; it should remove the cooper chip in time if it
is adhered on the driven bevel gear.
g. Coat the fastening bolt of driven bevel gear with the screw
lock agent, then tighten it to the specified torque.
Specified tightening force: 80-95N
m
Caution: It should be in the diagonal sequence to tighten the
bolt and tighten it for little, then tighten it to the specified
torque uniformly.
h. On press machine, use the special tools to press the inner
race of bearing into the bearing position on both sides of
differential housing.
i.
Place an adjusting shim in the position of front reducer
housing side bearing near exterior.
j.
Install another adjusting shim and the other side bearing outer
race in the front reducer housing with thedifferentialassembly
k. Install two bearing glands, left and right and use the wrench
to tighten the bolt to the specified torque.
Specified torque : 90-115N.m

1.Rotate the driven bevel gear, check the runout of
driven bevel gear.
Max. Runout: 0.07mm
Assembly of front reducer assembly
1.Install the adjusting washer in the drive bevel gear,
install the big bearing inner race of drive bevel gear
by press.
2. Clean the front reducer housing, install the outer
race of big and small bearing on the reducer housing
by press..
3. Install the drive bevel gear into the front reducer
housing, then install the washer, spacer and small
bearing inner race.
4.Use the special tools to install the drive bevel gear
oil seal.
Caution: It should coat the lip with the oil seal
lithium base grease before install it and the rear
surface of rear oil seal should flush with the top of
front reducer housing after knocked in.
5. Install the drive gear flange and dustproof cover
assembly.
(Refer to “Replacement of Drive Bevel Gear Oil Seal”)
6.Use the special tools to tighten the drive gear nut
to the specified torque; the nut should be precoated
with the lithium base grease.
specified torque : 140-200N
m
7. Use the torque measuring meter to measure the
pre-applied load of big and small bearing of drive
bevel gear.
Range of pre-applied load: 1.2-1.7N
