Disassembly (Fig. 30)
1. Remove differential assembly from machine (see
Differential Assembly in this section).
2. Remove six (6) socket head screws that secure cov-
er to housing. Note alignment of index marks on housing
and cover for assembly purposes (Fig. 31).
3. Place differential assembly on workbench so that the
differential is resting on the cover with housing orientat-
ed up.
4. Lift housing from differential assembly leaving inter-
nal components positioned on cover. For assembly pur-
poses, note that index mark on housing is aligned with
a gear pin that has one (1) gear (Fig. 33).
5. Note locations of projections on inside of cover for
assembly purposes. The projections need to be aligned
with the gear pins that have one (1) gear (Fig. 32).
6. Slide each gear pin with gears and spacers from cov-
er. Note location of gears and spacers on each of the six
(6) gear pins.
7. If necessary, remove ball bearings from cover and
housing. There are two (2) holes in the cover and hous-
ing that allow use of a pin punch to remove bearings.
Discard removed bearings.
Inspection (Fig. 30)
1. Clean all differential components.
2. Inspect all differential gears carefully looking for
chipped teeth, wear or other damage. Because gear
tooth damage is rarely isolated to one gear, replace
gears as a complete set.
3. Inspect gear pins (item 4) for scoring or wear.
4. Replace all worn or damaged differential assembly
components.
