REMOVAL
(1) Remove differential case from axle housing.
(2) Clamp Side Gear Holding Tool 6963-A in a vise.
(3) Position deferential case on the holding tool
(Fig. 33).
(4) Place shop towels around differential to cover
vise in order to prevent damage to ring gear when
removed.

gear to differential case.
(6) Using a soft hammer, drive ring gear from dif-
ferential case.
RING GEAR INSTALLATION
CAUTION: Do not reuse the bolts that held the ring
gear to the differential case. The bolts can fracture
causing extensive damage.
(1) Invert the differential case on Side Gear Hold-
ing Tool 6963-A.
(2) Position ring gear on the differential case and
start two new ring gear bolts. This will provide case-
–to–ring gear bolt hole alignment.
(3) Invert the differential case on Side Gear Hold-
ing Tool 6963-A.
(4) Install new ring gear bolts and alternately
tighten to 95–122 N·m (70–90 ft. lbs.) torque (Fig.
34).
(5) Install differential in axle housing and verify
differential side bearing preload, gear mesh, and con-
tact pattern.
PINION GEAR

ing.
(2) Mark pinion yoke and propeller shaft for
