7C INSPECTION AND REPAIR
INSPECTION AND REPAIR
PRECAUTION
(1) Several of the parts resemble each other; organize them so that they do not get mixed up.
(2) Clean each part with cleaning oil, clean out the oil holes and oil passages with compressed air,
and check that there are no obstructions.
(3) When using cleaning oil and compressed air, wear protective eyewear.
(4) If a clutch plate or brake band is replaced with a new one, soak it in ATF for 2 hours or more
before installing.
(5) Before assembly, apply ATF to all seal rings, rotating parts, and sliding parts.
(6) All seals, gaskets and roll pins must be replaced with new ones during assembly.
(7) Use petroleum jelly, not grease where required.
(8) When it is necessary to replace a bushing, replace the assembly which includes that bushing.
