Assembly (Fig. 3)
1. Assemble and install the input shaft.
A. Press the inner and outer bearings (items 7 and
8) onto input shaft until seated against bearing shoul-
ders.
B. Apply a light coat of oil to a new O--ring (item 6)
and install into input bearing bore of housing.
C. Install input shaft assembly in housing. Bearings
should slide easily into housing. Use a soft mallet to
tap the input shaft assembly into position if neces-
sary.
D. Install retaining ring (item 5).
E. Apply a light coat of oil to a new oil seal (item 9).
Protect oil seal lip from damage by input shaft splines
and install oil seal into input bearing bore of housing.
2. Install the intermediate shaft and gear assembly.
A. Apply a light coat of oil to a new O--rings (item 6)
and install into intermediate bearing bores of hous-
ing.
B. Apply a light coat of oil to a new O--rings (item 13)
and install onto bearing shoulders of intermediate
shaft.
C. Tilt small end of intermediate shaft assembly to-
ward opening in bottom of housing and position inter-
mediate shaft and gear assembly in housing.
D. Install the motor flange side bearing first. While
supporting the intermediate shaft and gear assembly
in position, fit the bearing (item 11) in housing bore.
E. Use a soft mallet to drive the bearing past the
O--ring and retaining ring groove.
F. Install retaining ring (item 5).
G. Repeat steps D. thru F. for opposite bearing.
H. Apply a rapid--curing anaerobic adhesive (Loctite
609 or equivalent) to the intermediate shaft bores.
Using a properly sized driver, install new end cap
plugs (item 10) with stamping outward until seated
against the retaining rings.
3. Assemble and install the differential case and final
drive gear.
A. Press bearings (items 15) onto differential case
until seated against bearing shoulders.
Transaxle
B. Position final drive gear over differential case and
install four (4) flange head bolts and lock nuts (items
17 and 18). Bolts should be installed from the differ-
ential flange side Tighten lock nuts from 55 to 63 ft- -
lb (75 to 85 N- -m).
NOTE: Bearing caps are marked for identification.
Letters or numbers are stamped in a horizontal or
vertical position. Make sure the bearing caps are in-
stalled in their original locations during assembly.
C. Position differential case assembly into transaxle
housing and install bearing caps (item 2). Tighten
bearing cap bolts from 35 to 45 ft- -lb (47 to 61 N- -m).
D. Apply a small bead of silicone sealant around the
entire cover plate sealing surface. Sealant should be
applied to the inside of the cover plate mounting
holes.
E. Install the cover plate and cover plate screws.
Tighten cover plate screws from 16 to 24 ft- -lb (22 to
33 N- -m).
4. Install the axle shaft and bearing assembly (Fig. 4).

3. Bearing
A. Using a seal driver, install the oil seal into the axle
housing. Drive the oil seal to a depth of 1.125 in.
(28.6 mm).
B. Install the inner retaining ring.
C. Install the bearing to the axle shaft by supporting
the inner race of the bearing in an arbor press, and
apply pressure to the differential end of the axle
shaft. Make sure the bearing seats against the shoul-
der of the axle shaft.
