REMOVING AND REFITTING THE FLYWHEEL

IS IT NECESSARY?

The flywheel will have to come off if it retains the bearing or bush. Otherwise, it can stay in place. The bolts may be held by locking tabs, Loctite or simply by being very, very tight. Use a breaker bar.

FIND TDC

You’ll need to lock the engine to undo the flywheel bolts. Turn engine to TDC of cylinder one (the rotor arm points to the number one segment in the cap). This ensures both valves are safely closed.

LOCK THE ENGINE

Turn the engine backwards past TDC and feed a length of a cut fan belt into the spark plug hole. Turn the engine toward TDC until it stops. Now the bolts can be undone without the crank turning.
