NOTE: The front housing contains the countershaft
front bearing race. The rear housing contains the
countershaft rear bearing race. Be advised that
these components are NOT serviceable items. The
front housing will have to be replaced if the coun-
tershaft bearing race is loose, worn, or damaged.
The rear housing will have to be replaced if the
countershaft rear bearing race is loose, worn, or
damaged.
Inspect the input shaft bearing retainer. Be sure
the release bearing slide surface of the retainer is in
good condition. Minor nicks on the surface can be
smoothed off with 320/420 grit emery cloth and final
polished with oil coated crocus cloth. Replace the
retainer seal if necessary.
Inspect the output shaft bearing retainer. Be sure
the U-shaped retainer is flat and free of distortion.
Replace the retainer if the threads are damaged, or if
the retainer is bent, or cracked.
COUNTERSHAFT BEARINGS AND RACES
The countershaft bearings and races are machine
lapped during manufacture to form matched sets.
The bearings and races should not be interchanged.
NOTE: The bearing races are a permanent press fit
in the housings and are NOT serviceable. If a bear-
ing race becomes damaged, it will be necessary to
replace the front or rear housing as necessary. A
new countershaft bearing will be supplied with each
new housing for service use.
The countershaft bearings can be installed back-
wards if care is not exercised. The bearing roller cage
is a different diameter on each side. Be sure the
bearing is installed so the large diameter side of the
cage is facing the countershaft gear (Fig. 135). The
small diameter side goes in the bearing race.
REVERSE IDLER COMPONENTS
Inspect the idler gear, bearing, shaft, thrust
washer, wave washer and thrust plate. Replace the
bearing if any of the needle bearing rollers are worn,
chipped, cracked, flat-spotted, or brinnelled. Also
replace the bearing if the plastic bearing cage is
damaged or distorted.
Replace the thrust washer, wave washer, or thrust
plate if cracked, chipped, or worn. Replace the idler
gear if the teeth are chipped, cracked or worn thin.
Replace the shaft if worn, scored, or the bolt threads
are damaged beyond repair. Replace the support seg-
ment if cracked, or chipped and replace the idler
attaching bolts if the threads are damaged.
