Hello All,
I am new to this forum, but have enjoyed the threads. I have recently split my engine case ( 1972, 750 Combat, 206412). I was first happy to see that it had FAG bearings, which led me to the conclusion the case has been opened before. But my problem is the main bearings are not a tight fit in the engine cases. They are snug fit but I can pull them out. I also see that the outer main bearing cases have wear marks which indicate to me that they have rotated in the case. Could this have been cause, by a previous bearing disaster. I also noted the on one lobe of the camshaft there is a punch mark which may have been caused I suspect by a push rod.
Any suggestions on the bearing case? I suspect some welding and machining.
Thanks in advance Bryan.
