tion and volume of the oil.
3. Remove the coupling (7) from the spindle end.
4. Remove the retaining ring (6G) out of the groove in
the Ring gear (1F) with a screw driver by prying out
the open end of retaining ring then completely pull
the retaining ring out of the groove by grasping the
loose end with the pliers.
5. Remove the cover sub-assembly (6) from the unit. To
remove the cover out of the unit, the unit needs to
be carefully pressurized with air. Washer (2) may have
to be removed separately due to the loose attach-
ment.
6. Remove first stage sun gear (10) (if applicable).
NOTE:
Units with ratios greater than 36:1 numerically will
not have separate first stage sun gear (10), as the
