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.

Operation test of vacuum booster
Remark: check the operation of vacuum booster with the
vacuum booster tester if workable.
1.Operation inspection
(a) Before starting the engine, tread down the brake pedal
several times, and check the pedal reservation distance to
ensure there is no change occurs.
(b) Tread down the brake pedal and start the engine. If the
treaded pedals continue to move downward, which means
the operation is normal.
1. Inspection on Air-tight
(a) Start the engine for 1-2 min and then turn it off. Then
tread down the brake pedal slowly for several times, if the
pedal move downward continuously in the first, but
return gradually in the second or third time, which means
the vacuum booster has a good air-tight.
(b) Tread down the brake pedal when the engine is working,
then stop the engine, but tread the pedal down. If the
reservation distance doesnít change within the 30 seconds,
which shows the air tight of vacuum booster is good.
Air-bleeding of braking system
Remark: air-bleeding is required if any operation for braking
system is conducted or the pipe line is doubted to have air.
1. Fill the oil cup with the brake liquid
Check the liquid level of oil cup after the air in each wheel
brake pump is exhausted. If necessary, add the brake liquid.
2. Connect the vinyl resin pipe with the vent screws.
Insert the other end of pipe into the container with half brake
liquid.
Remark: the air-bleeding shall begin from the longest pipe line
when the wheel-brake cylinder is exhausting the air.
3. Air exhaust of the pipe line in braking system
(a) Tread down brake pedal slowly several times.
(b) Loosen the vent screws until the brake liquid flows out
while letting the assistant tread down the pedal. Then
screw up the vent screws.
(c) Repeat this approach until there is no air in the liquid.
4. Repeat the approach for the wheel-brake cylinder.

Change of power steering liquid
1. Tear down the oil-returning hose from the oil cup to
drain the liquid into the container;
2. Run the engine in the idle status, and rotate the
steering wheel toward the max rotating angle for
several times in right or left direction while draining the
liquid, until the oil in steering liquid is drained up.
3. Turn off the engine.
4. Connect the oil-returning pipe and inject the new
power steering liquid in the liquid tank;
