Gearbox Disassembly Procedure
1. Drain all gear oil from the gearbox by removing the drain plug located on the gearbox hous-
ing below the gearbox mounting flange.
2. Remove the 8 inspection cover bolts from the top of the gearbox. Remove the inspection
cover to expose the input shaft.
3. Remove the bolts from blank cap. Remove the blank cap taking care not to damage the gas-
ket between the cap and housing.
4. Remove the retaining ring between the shaft and gear (for gearboxes with gears on the back
side of the input shaft only).
5. Press out input shaft through blank cap hole. This will remove the race and allow the shaft
to slide out. Gear may be removed through the top of the gearbox housing. Seal, retaining
ring, and race may be removed from the front of the gearbox if necessary. It is very im-
portant to make note of the location of the shims used when removing the input shaft.
6. Remove the cotter pin and retaining nut from the output shaft. The output gear will slide off
of the output shaft. Remove any shims that may be present.
7. Remove seal protector from output of gearbox housing and remove the retaining ring under-
neath.
8. The output shaft assembly will have to be pressed out from the inside or it can be pulled out
through the bottom of the housing. The output seal, spacer, and lower bearing will be re-
moved with the shaft. The upper bearing will be pressed off the end of the shaft.
9. If any of the bearing races in the housing need to be removed, a blind hole bearing puller
should be used.
10. See page 20-21 for parts breakdown.
