Ducati Diavel Service Manual: Checking the camshafts and supports

Ducati Diavel Service Manual / Engine / 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.

Checking the camshafts and supports


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.
