Overhaul cam shaft (Ducati ST2)

0

Check that the work surfaces of the cams are free of scratches, grooves, steps and waving. Worn cams are often the cause of irregular timing which reduces the power of the engine.

Insert the cam shaft between two tailstocks and check the deviation using two dial gauges:

• limit: 0.1 mm/0.004 in.

Cam shaft supports

The supports consist of a light alloy casting with a bearing inside.

Check the state of wear of the bearing (see "Bearings").

To remove it from its support, use a universal puller.

Caution! Do not refit bearings which have been removed.

Lubricate all the components before refitting.

Fit the bearing with the shield (A) facing outwards.
