(18) Install reverse fork bracket and reverse lock-
out. Tighten screws to 11 N·m (96 in. lbs.) torque
(Fig. 61) (Fig. 62).

BEARING ADJUSTMENT PROCEDURE
(1) Use extreme care when removing and install-
ing bearing cups and cones. Use only an arbor press
for installation, as a hammer may not properly align
the bearing cup or cone. Burrs or nicks on the bear-
ing seat gives a false end–play reading while gauging
for proper shims. Improperly seated bearing cups and
cones are subject to low–mileage failure.
(2) Bearing cups and cones should be replaced if
they show signs of pitting or heat distress. If distress

is seen on either the cup or bearing rollers, both cup
and cone must be replaced.
(3) Bearing preload and drag torque specifications
must be maintained to avoid premature bearing fail-
ures. Used (original) bearings may lose up to 50% of
the original drag torque after break–in. All bearing
adjustments must be made with no other component
interference or gear intermesh.
(4) Replace bearings as a pair: If one differential
bearing is defective, replace both differential bear-
ings, if one input shaft bearing is defective, replace
both input shaft bearings.
(5) Bearing cones must not be reused if removed.
(6) Turning–torque readings should be obtained
while smoothly rotating in either direction.
DIFFERENTIAL BEARING PRELOAD ADJUSTMENT
NOTE: True bearing turning–torque readings can be
obtained only with the geartrain removed from the
case.
(1) Remove bearing cup and existing shim from
clutch bellhousing case.
(2) Press in new bearing cup into bellhousing case
(or use a cup that has been ground down on the
outer edge for ease of measurement).
(3) Press in new bearing cup into gear case side.
(4) Oil differential bearings with transmission
fluid. Install differential assembly in transaxle gear
case. Install clutch bellhousing over gear case. Install
and torque case bolts to 29 N·m (21 ft. lbs.).
(5) Position transaxle with bellhousing facing
down on workbench with C-clamps. Position dial
indicator.
