Administrators BRAAP Posted June 5, 2007 Administrators Share Posted June 5, 2007 OUCH!!! Thrust is trashed! It is somewhat common to weld the thrust surface and have it reground, I’d prefer to find another crank which may end up being easier and less expensive in the long run. Is this a crank that you picked up elsewhere, or out of your engine? When installing the crank, don’t forget to not only make sure there is adequate thrust clearance, but also, make sure you “set†the thrust bearings while installing the main caps. FWIW, one of the most common causes for trashed thrust surfaces like that in a manual transmission car is holding the clutch in for extended periods while the engine is running, another cause is an improperly set thrust when the crank was originally installed.
