DISASSEMBLY OF THE CASE

Step 6

Planetary gears & bearings may

be replaced by driving out the

pins. (On some early model

units, these pins were held in

place by a small roll pin). By

pushing the planetary pins out

with a 5/16” drift punch, the roll

pins will shear. Inspect the

thrush washers, needle bear-

ings, planetary pins and gears

for wear.

Units produced today do not use

the planetary pins retained by a

roll pin. To keep these planetary

pins in place we use a snap ring

retainer that fits underneath the

synchro-teeth. To prevent the pin from spinning and/or moving

back and forth, we also started putting a small tack weld on the

bottom of each pin.

Step C1

Using a 9/16” wrench, remove the 4 cap screws holding the

bearing cap.

Bearing cap & screws removed. (During the reassembly, the

4-3/8” cap screws should be torqued to 19 ft./lbs., and the 1/4”

cap screw to 6 ft./lbs. of torque)

Step C2

Remove the cotter pin that locks the nut to the spline shaft.

Step C3

Remove the nut using a 12” adjustable wrench. The shift

fork must be at the rear of the case, locking the unit in the

overdrive position before the nut can be removed.

Step C4

Remove the shift detent screw, ball and spring.
