Disassembly profeller shaft
After disassembly profeller shaft, stuff the ouput port of trassmition case with a plug.
Disassembly axle casehalf shaft. (Refer to rear axle part)
Attention：
When disassembly profeller shaft,take care to aviod
damaging splin, socket flange yoke and oil seal.
Assembly
Fully Inject the recommendatory gear lubricating
oil.

Disasembly
Pre-check
Before disassembly drive differential, check the following:
Preload force
1）Turn drive gear for several times to put bearing in
its right position.
2） Use tool check the preload force.
Clearance between driven gear and drive gear.
Measure the clearance of main reduct gear at different
points with a micrometer gauge.
Radial run-out of driven gear
Measure the radial run-out of driven gear with a
micrometer gauge.
Gear contact area
Checking of gear contact area refers to Adjusting.
Clearance between half shaft gear and planetary gear.
Use a thickness gauge to measure the clearance
between the thrust gasket of half shaft gear and differential
housing.

Differential
1 .Fixing main differential ass'y by tool.
2 .Mark the seat of hakf shaft bearing with paint or a
special tool to avoid mistaking in reassembly.
Since the bearing seat is linear bored in machining, it
should be in its former position when reassembly it.
3.Diassembly locking pin of lower half shaft and
bearing seat of half shaft.
4 .Disaaembly adjusting spacer of lower hafl shaft by
tool.
