02.38 THE CAMSHAFT BUSHES
A new bush should be immersed in clean engine
lubricating oil for four hours before fitting. A small
identification dot is on one outside edge of the bush
and on assembly this dot must be towards the top of
the crankcase. It is recommended that bushes are
replaced as a set.
To gain access to the flywheel end expansion plug
and bush it will be necessary to remove the flywheel,
fanshroud and main bearing housing.
