During inspection of the main bearing shells and housings of a medium speed diesel engine it is found that there is evidence of fretting at some of the bearing shell joint faces, the bearing housing joint faces and also between the back of the bearings and the bearing pocket. What is the cause of these defects?

The probable cause of such damage is an insufficient tightening of the main bearing bolts.
