ASSEMBLY

CAUTIONDo not reuse the gasket, O-ring, oil seal. Always replace with a new one when assembling. Do not use grease. Use petroleum jelly (i.e. Vaseline). Apply ATF to friction components, rotating parts, and sliding parts before installation. Immerse new clutch discs or brake discs in ATF for at least two hours before assembling them. When replacing a bushing, replace the assembly which it belongs to. Do not use cloth gloves or shop towels during assembly. Use nylon cloth or other lint-free material.
