• If any crack, damage, or excessive wear is found on cam face of
baulk ring or working face of insert, replace it.
Bearing
Check bearing for damage and rough rotation. If necessary, replace
with new one.
CAUTION:
Bearing preloading shim: after the intermediate adjusting shim
and/or the 6th main gear, 5th main gear, and 4th main gear have
been replaced, it is necessary to modify the bearing preload
setting by changing the bearing preload shim.
• When replacing tapered roller bearing, replace outer and inner
races as a set.
• Replacing the intermediate adjusting shim.
- Increase the size of the bearing preload shim, if the replaced
intermediate adjusting shim is thinner than the shim used before.
- Decrease the size of the bearing preload shim, if the replaced intermediate adjusting shim is thicker
than the shim used before.
• Replacing the 6th main gear, 5th main gear, and 4th main gear.
- Measure the thickness of the main gear used before and the new main gear.
- Increase the thickness of the bearing preload shim, if the difference is smaller than 0.025 mm (0.0010
in).
- Decrease the thickness of the bearing preload shim, if the difference is greater than 0.025 mm
(0.0010 in).
ASSEMBLY
1. Press-fit the mainshaft front bearing inner race (1) onto the
mainshaft using Tool (A).
2. Install 1st main gear (1), and 1st-2nd synchronizer assembly (2)
onto the mainshaft.
3. Press-fit the bushing (3) onto the mainshaft using Tool (A).
