CAM CHAIN GUIDE AND CAM CHAIN
TENSIONER
Check the cam chain guide and cam chain tensioner for
wear and damage. If it is found to be damaged, replace it
with a new one.

CAMSHAFT

CAMSHAFT INSPECTION
If the engine produces abnormal noises, vibration or lacks
power, a camshaft may be distorted or worn to the service
limit. The camshaft runout should be checked. Also, check
the cams and journals for wear or damage.
CAM WEAR
Worn-down cams are often the cause of mistimed valve
operation resulting in reduced power output. Measure the
cam height using the micrometer. Replace a camshaft if
the cams are worn to the service limit.

CAMSHAFT JOURNAL WEAR

installed in place. Measure the clearance using the plasti-
gauge
