bearing race protrudes 0.3 in. above the front surface
of the clutch housing. Install bearing race with
Remover/Installer 8237 and Handle C-4171.
(2) Install countershaft front bearing race into the
clutch housing so that the bearing race protrudes 0.4
in. above the front surface of the clutch housing.

the countershaft front bearing bore in the clutch
housing (Fig. 78).
(4) Clean all old sealer from the input shaft
retainer and the clutch housing butDO NOTapply
new sealer at this time. New sealer will be applied
after all the preload measurements are made and
end-play shims are installed.
