Ducati SUPERBIKE 848 MY 2008 Manual page 474

Cylinder head assemblies: camshafts
If necessary, unscrew the stud bolts (2) from the cylinder heads.
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 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.
