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

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
