Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil and working
fluid, fuel and exhaust gas.

Bleed air from passages in pipes and tubes of applicable lines, such as in cooling system.

After cooling down engine, again check amounts of engine coolant, engine oil and working fluid. Refill to
specified level, if necessary.

and remove mounting bolts.

Loosen mounting bolts in diagonal order.
CAUTION:

Do not disassemble drive plate.

Never place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
