If any crack, damage, or excessive wear is found on cam face of
baulk ring or working face of insert, replace it.
Bearing
Check items below. If necessary, replace them with new ones.
CAUTION:
When replacing tapered roller bearing, replace outer and inner
races as a set.

Damage and rough rotation of bearing
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.

Replacing the intermediate adjusting shim.
–Increase the size of the bearing preload shim, if the replaced intermediate adjusting shim is thin-
ner 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).
