Checking The Camshafts And Supports - Ducati Diavel Workshop Manual

Cylinder head assemblies: camshafts

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 run-out on the areas indicated 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.
