Replacing camshaft bearings during an engine rebuild is a no-brainer, but don’t take the process lightly. The intelligent approach is to handle the job with as much planning and precision as you would if replacing main or rod bearings. Simply knocking out the old bearings and installing fresh ones with little regard to bearing selection, sizing or alignment is a big mistake. Ill-fitting cam bearings can result in damaging both the camshaft and/or main and rod bearings.
