AUTOMATIC TRANSAXLE
_,sGENERAL INFORMATION
NZlBABTaCautionary points during disassembly and
assembly of the transaxle
Because the automatic transaxle is composed ofcomponent parts of an especially high degree of
precision, these parts should be very carefully
handled during disassembly and assembly so asnot to scar or scratch them.
A rubber mat should be placed on the work-
bench, and it should always be kept clean.
During disassembly, cloth gloves or shop towelsshould not be used.
If such items must be used, use articles made ofnylon, or use paper towels.
All
disassemblyed parts must be thoroughly
cleaned.Metal parts may be cleaned with ordinary
detergents, but must be thoroughly air dried.
Clean the clutch disc, resin thrust plate and
rubber parts by using ATF (automatic transmis-
sion fluid), being very careful that dust, dirt, etc.
do not adhere.
Do not reuse gaskets, oil seals and rubber parts.Replace them with new ones at every reassem-
bly. O-ring of oil level gauge need not be
replaced.Do not use grease other than petrolatum jelly.
Apply ATF to friction element, rotating parts, andsliding parts before installation.
New clutch disc should be immersed in ATF for
more than two hours before installation.
Do not apply sealer or adhesive to gaskets.
When bushing must be replaced, replace
assembly which includes it.
If the transaxle main unit is damaged, also
disassembly and clean the cooler system.
In order to prevent a sudden start as a result of
accidental misoperation of the select lever, this
model is provided with the automatic-transaxle
safety-lock system.
