INSPECTION
CAMSHAFT
Rotate the outer loop of the camshaft bearing by
hand. The rotation must be smooth and without
noise. Check if the inner ring of the bearing fits
tightly with the camshaft. If they do not match
tightly, replace the camshaft with a new one.
Worn-down cams are often the cause of mistimed
valve operation resulting in reduced output
power. The limit of cam wear is specified for both
intake and exhaust cams in terms of cam height,
which is to be measured with a micrometer.
Replace the camshaft if fount it worn down to the
limit.
