General
Precautions to be taken when disassembling and the
Because the automatic transaxle is of component parts of especially high degree of
precision, these parts should be very carefully han dled during disassembly and assembly so as not
to scar or scratch them.
A rubber mat should be placed on the and it should always be kept clean.
During disassembly, cloth gloves or shop towels, sh ould not be used.
such items must be used,
either use articles made of nylon, or use paper tow els.
All disassembled parts must be thoroughly cleaned.
Metal parts may be cleaned with ordinary but must thoroughly air dried.
Clean the clutch disc, resin thrust plate and rubbe r parts by using ATF (automatic transmission fluid) ,
being very careful that dust, dirt, etc. do not adhere to them.
Do not reuse gaskets, oil seals, or, rubber parts.
Replace such parts with new ones at every reassembl y. The oil’ gauge need not
be replaced.
Do not use grease other than petrolatum jelly.
Apply ATF to friction components, rotating
and sliding parts before installation.
A new clutch disc should be immersed in ATF for at least two hours before installation.
Do not apply sealer or adhesive to gaskets.
When a bushing must be replaced, replace the assemb ly in which it is incorporated:,
If the transaxle main unit is damaged, also disasse
mble and clean the ‘cooler system.,
