12.16.Careful application of a propane torch (NOT oxy-
accetelene), or heating the housing in an oven
for about ten minutes at 250 deg. F. will expand
the alloy housing faster than the steel bearing,
allowing for easy removal of the bearing.
NOTE: An oven that is to be used for food prep-
aration should not be used for transmission
preparation.
12.17.Clean and inspect the gears, shafts, shift collar,
and housings. See Figure 12.17.
• Visually check the gears for: worn or damaged
teeth, worn holes that engage the dogs on the
shift collar, discoloration, scoring or metal trans-
fer on the recessed surface, or damaged inner
bushings. The gear should be replaced if the
inner bushing is discolored, scored, or non-circu-
lar.
• Visually check the shafts for: worn or damaged
teeth, discoloration, or damage to any bearing
surfaces.
• Visually check the shift collar for worn or
rounded dogs, cracks, or discoloration. If there
is significant damage to the shift collar or the
shift collar’s engagement points on the forward
and reverse gears, shift linkage maladjustment
or improper use may be the core problem.
• Inspect the differential assembly. Differential
repair, if necessary, is covered in a separate sec-
tion.

12.18.Replace any suspect parts and assemble the
transaxle.
• If the input shaft or the bearings that carry it
have been replaced, test-assemble the housing
without sealant and check shaft end-play with a
dial indicator. Shim it as necessary to obtain
.002 to .006 end play. There is a shim kit
described in the Illustrated Parts List.
• Warming the transaxle housings, or chilling the
bearings prior to installation will ease the pro-
cess.
• Seal the two halves of the housing together with
a non-silicone based gasket material such as
Loctite 518 (red) sealant.
• On the bolts securing the housing halves
together, use new self-locking nuts or apply a
thread locking compound such as Loctite 242
(blue) to the threads, and tighten them to a
torque of 95 + 10 in.-lbs.
• Protect seal lips during shaft installation, and
press them flush with the housings using a seal
driver. See Figure 12.18.
• Install new “O” ring on the drain plug, and tighten
it securely.
• Install the detent ball, spring, and set screw in
their bore. A small quantity of Teflon thread
sealant may be used on the set screw. Tighten it
until a shift torque of 8 to 14 ft.-lbs. is achieved at
the shift actuator assembly.
