Assembly:

——The assembly of the transmission is in reverse

of its disassembly, pay attention to the below
items:

1. Assemble differential assembly on clutch

housing, at first do not assemble output flange.

2. Assemble output shaft and output shaft front

bearing plate, plug into fixing bolt and fasten
by 40Nm moment.

3. Assemble thrust shim needle bearing. Pay

attention to the direction of the thrust shim, the
inside diameter of thrust shim A should be
integrate closely with the bearing holder. Pay
attention that don’t mix up the 1st and 2nd
synchronizer ring, 1st synchronizer ring is not
sprayed molybdenum and has three gears
missing.

——The side with gears A towards 1st driven gear

B when you assemble the 1st and 2nd
synchronizer.

——Assemble reverse gear idler and idler shaft

onto clutch housing.

——Assemble the needle bearing, synchronizer

ring, and gear of 2nd and 3rd driven gear.
When you assemble the 3rd driven gear, make
sure that the side with bulge towards 2nd
driven gear.

——Use snap ring to adjust the axial size after the

assembly of 3rd driven gear. Choose the
