these procedures.
2. Carefully position transaxle with drive tire mounting
studs down. Support transaxle with wooden blocks
to stabilize.
3. Use solvent to clean outside of transaxle before re-
moving seal.
NOTE: Removal is destructive to the seal.
4. Puncture seal with a flat screwdriver (carefully near
center of seal to avoid damaging bearing) and pry
around the edge under the seal to remove from
cover.
5. Clean around flange to remove any dirt or debris.
6. Install input seal using Yale input seal installation
tool (refer to section General, Special Tools).
NOTE: It is recommended to verify the torque on the
transaxle cover capscrews before reinstalling the trac-

of the transaxle are press fit and cannot be repaired
or properly preloaded without specialized equipment.
If a leak develops from between the cover and the
housing, different procedures are required depending
on whether your transaxle is within the warranty period
or beyond the warranty period. Refer to section During
the Transaxle Warranty Period or After the Transaxle
Warranty Period.
