VALVE RECONDITIONING CONTINUED
Valve Rotator Continued
Wear on outside surface of locks can be caused by overspeeding engine.
5. Clean parts thoroughly in solvent. Check ribs inside of locks to be sure that none are worn enough to cause
looseness. Locks must be fit snugly into valve stem groove. Check locks for wear on outside surface which
might allow valve spring retainer to slide over lock. Replace if in doubt.
