CLEANING
Clean gears, shafts, shift components and transmission housings with a standard parts cleaning solvent. Do not use
acid or corrosive base solvents. Dry all parts except bearings with compressed air.
Clean shaft bearings with a mild solvent such as MOPAR
degreasing solvent, Gunkor similar solvents. Do not
dry the bearings with compressed air. Allow the bearings to either air dry or wipe them dry with clean shop towels.
INSPECTION
NOTE: Minor corrosion, nicks, or pitting can be
smoothed with 400 grit emery and polished out
with crocus cloth.

spotted or brinnelled.
Gears:Inspect for worn, chipped or cracked teeth.
Inspect bearing surfaces for wear or flat-spotted.
Mainshaft:Inspect for worn splines, snap ring
grooves and threads.
Countershaft:Inspect all gears for worn, chipped or
cracked teeth (1). Inspect all bearings (2) and bearing
surfaces for ware or flat-spotted.The countershaft is
serviced as an assembly, except for bearings.
Oil slinger:Inspect first/reverse oil slinger for cracks.
Synchronizer components:Inspect for worn,
chipped or cracked teeth and burned or flaking off fric-
tion material.Synchronizer are serviced as an
assembly.
Input Shaft:Inspect shaft (1), bearing (2) surfaces for
wear or flat-spotted. Inspect fifth gear (3) for worn,
chipped or cracked teeth. Inspect splines (4) for wear
and chips.

ADJUSTMENTS
MAINSHAFT/COUNTERSHAFT BEARING PRELOAD
CAUTION: This procedure must be performed any time a mainshaft, countershaft or input shaft bearing or
shaft is replaced. Failure to follow these instructions will result in damaging the transmission.
MAINSHAFT
1. Set mainshaft, input shaft and countershaft into the
rear housing. Rotate the shafts to seat bearing in
rear housing.
2. Remove mainshaft bearing cup, shims and oiler
washer from the front housing.
3. Position Measurement Fixture 9592 (1) on front
housing over the mainshaft bearing cup bore.
4. Loosen the knob (2) on the fixture and lower the
shaft onto the mainshaft bearing cup (3) bore
shoulder. Then tighten the knob to hold the shaft.
5. Remove the fixture from the front housing.

8. Measure the gap (1) between the fixture shaft (2)
and the fixture plunger (3). Repeat measurement
on the opposite side of the countershaft cup and
bearing. The average of the two measurements,
will be the size of the countershaft select shim.
9. Install select shim in front housing countershaft
bearing cup bore and install bearing cup.
