Good afternoon all. I am seeking advice as to the proper way to size new camshaft bearings after installation. After searching the forums here and recieving "advice" from various sources, I have come to the conclusion that there is a difference of opinion on this. I have done various rebiulds before but this is the first time I have installed single piece bearings. The old bearings were drawn out correctly with a threaded rod and properly sized puck, so no damage to mating surfaces. New Clevite bearings were installed in the same manner. No hammers here! The bearings fit nicely on the new cam which was in tolerance when miced. So, that being said, the bearings after install are to tight. No surprises there. The confusion is how to size them. I have heard to use a brake caliper hone, a bearing scraper, inline boring, to force it in and let it burn clear. The two options I am considering are a hone or inline boring. The hone seems the most economical but was told to avoid this because of contaminants getting into the bearing. Inline boring seems expensive for a simple fix. Bearings are straight and round and I need about .002 off. Any advice on this would be greatly appreciated! Thanks. Art the beekeeper.
