27

REMOVE CAMSHAFT SUB-ASSEMBLY RH

NOTE:



Do not loosen or remove the 4 bolts that are not indicated by
the arrows shown below. If any of them are loosened or
removed, the backlash of the gear in the timing tube will go out
of adjustment. In this case, replace the timing tube assembly
with a new one.



Be careful not to damage the cylinder head with the wrench.

NOTE:



As the thrust clearance of the camshaft is small, the camshaft must
be kept level while it is being removed. If the camshaft is not kept
level, the portion of the cylinder head which receives the shaft thrust
may crack or be damaged. To avoid this, the following steps should
be carried out.



Having the crankshaft pulley at a wrong angle can cause the piston
head and valve head to come into contact with each other when
removing the camshaft. Always set the crankshaft pulley at the
correct angle as shown below.
