Part: Cam Center Chain Roller for Honda CB450 / CL450 / CB500T Motorcycles
Why You Need This: Doing a top end engine rebuild on your Honda CB450 / CL450 / CB500T is the perfect time to inspect the cam chain tensioner parts for any signs of wear or damage. This is a replacement "large" center roller noted as roller "B" located between the cylinders and the upper part of the crankcase. If your roller is chewed up, then it is time to replace it before putting the engine all back together. This is an exact copy of the original roller.
While you are swapping out the cam chain roller, it might be a good time to replace the old cam chain for a fresh one, which you can find here. We also recommend you finish the rebuild with a new overhaul gasket kit, and gasket sealer to make sure everything is sealed up right to minimize the chances of future leaking.
Installation Tip: Lubricate the roller pin prior to installation with assembly lubricant.
