TRANSMISSION ASSEMBLY

3.

Using filler gauge put and press baulk ring on gear taper cone,
and then measure “clearance C” at more then 2 diagonal points,
and calculate the average.

●

Reverse synchronizer
Push baulk ring on the cone and measure baulk ring back sur-
face clearance at two locations or more on opposite sides, find
the average value, and replace if it is outside the limit value.

Bearing

If the bearing does not rotate smoothly or the contact surface on ball
or race is damaged or peeled, replace with new ones.

ASSEMBLY

the front side.

●

Do not reuse 5th-6th coupling sleeve and 5th-6th syn-
chronizer hub.

●

Replace 5th-6th coupling sleeve and 5th-6th synchro-
nizer hub as a set.

2.

Install 5th-6th spread spring in the 5th-6th shifting insert.

CAUTION:

●

Do not install 5th-6th spread spring hook onto the same
5th- 6th shifting insert.

●

Be careful with the shape of reverse shifting insert to
avoid misassembly.

3.

Install 6th needle bearing, 6th main gear, and 6th baulk ring on
the main shaft and then using an inserter and a press to press fit
the 5th-6th synchronizer assembly.

CAUTION:

●

Do not reuse 5th-6th synchronizer hub.

●

When press fitting, install with the side having the three
boss edge oil grooves facing the rear side.
