Engine
Checking the camshafts and supports
Check the cam contact surfaces for scratches, grooves, steps and waving.
Worn cams are frequently the cause of poor timing, which leads to loss of engine power.
Place the camshaft between two centres and check the runout using two dial gauges.
Service limit: 0.1 mm.
Visually inspect the camshaft tracks for scoring and abnormal wear. If any of the above defects are found, the camshaft should
be renewed.
If you find scoring or excessive wear, check the operation of the engine lubrication circuit.
