securing the camshaft caps of the inlet camshaft to
the cylinder head.

and remove one camshaft before starting
to release the other. If both camshafts are
progressively released at the same time, the
valves may contact each other and cause damage
to the valve head areas and valve stems.

The inlet and exhaust camshafts are different.
They can be identified by a plain area in the
centre of the exhaust cam and a groove in the
same place on the inlet cam.
