Disassembly (Fig. 3)
CAUTION
The transaxle assembly is a precision assembly,
and any repair or replacement of parts must be
done with great care in a clean environment.
Handle all components (especially gears) with
extreme care.
1. Remove the drain plug (item 21) and drain the oil
from the transaxle assembly.
2. Remove the axle shaft and bearing assembly.
A. Remove the outer retaining ring (item 26).
B. Using a slide hammer attached to the threads on
the end of the axle shaft, remove the axle shaft and
bearing assembly from the axle housing.
C. Remove the inner retaining ring. Use caution to
not damage the bearing surface.
D. Using an oil seal puller attached to a slide ham-
mer, remove the oil seal from the axle housing and
discard (item 25).
E. Remove the bearing (item 27) from the axle shaft
by supporting the inner race of the bearing in an ar-
bor press, and apply pressure to the wheel hub end
of the axle shaft.
F. Repeat procedure for opposite side.
3. Remove the differential case and final drive gear.
A. Remove the ten cover plate screws (item 22).
B. Using a putty knife, separate the cover plate (item
20) from the transaxle housing. Be careful not to
damage the housing sealing surface or deform the
cover plate.
NOTE: Bearing caps are marked for identification.
Letters or numbers are stamped in a horizontal or
vertical position. To assure correct assembly, note
the bearing cap locations.
C. Remove the four (4) bearing cap screws (item 3)
Remove bearing caps and lift differential case from
axle housing.
D. Using a bearing puller, remove bearings
(item 15) from each end of the differential case.
E. Remove the four (4) flange head bolts and lock
nuts securing the ring gear to the differential case
and remove the ring gear.

4. Remove the intermediate shaft and gear assembly.
A. Punch or drill a small hole in the center of each
end cap plug (item 10). Insert a suitable sheet metal
screw into the hole until the the cap plug is driven
from the housing bore.
B. Remove retaining rings (item 5) from intermedi-
ate shaft bores.
C. From the motor flange side of the housing, use a
brass drift and drive the intermediate shaft in enough
to allow engagement of an I.D. bearing puller.
D. Using an I.D. bearing puller attached to a slide
hammer, remove the bearing from the motor flange
side of the housing.
E. Repeat steps C. and D. for remaining bearing.
F. Tilt small end of intermediate shaft assembly to-
ward opening in bottom of housing and remove.
G. Remove and discard O--rings (item 6) from inter-
mediate bearing bores.
H. Remove and discard O--rings (item 13) from in-
termediate shaft bearing shoulders.
5. Remove input shaft assembly.
A. Remove oil seal (item 9) from input shaft bore.
B. Remove retaining ring (item 5) from input shaft
bore.
C. Pull input shaft assembly from housing. The input
shaft assembly should slide out of the housing easily.
Use a slide hammer attached to the input shaft if nec-
essary for removal.
D. Using a bearing puller, remove inner and outer
bearings (item 7 and 8) from the input shaft.
E. Remove and discard O--ring (item 6) from input
bearing bore.
6. Clean any residual sealant from transaxle housing at
intermediate shaft bearing bores and cover plate seal-
ing surface, and from cover plate.
7. Inspect all parts for signs of wear or damage. Bearing
and seal surfaces should be free of pitting, wear, or signs
of overheating. Gears should be free of pitting, wear or
scoring. Inspect axle shafts for worn splines, bends or
cracks. Replace worn or damaged parts as necessary.
