It is imperative that the inner cam bearing removal is done and they are replaced whenever performing maintenance, repairs, or upgrades to your Twin Cam cam compartment.

A specialty tool is needed to, both, cam bearing removal and to replace the cam bearings. Do not attempt replacing these cam bearings without using a tool that is specifically designed for this job.

Before completing cam bearing removal of the old bearings it is important to inspect the old bearings, as they sit, in the right side crankcase. If one or both of these bearings are damaged or missing material, a closer inspection will be needed in order to scavenge the broken fragments. The same goes for the cam plate bearings.

If one or both bearings are broken and apart, the bottom end will need to be pulled from the frame so that the crankcases can be split and completely cleaned. If, even one small needle bearing or piece of metal debris is left behind, it can inevitably be catastrophic to the motor upon reassembly.

Torrington inner cam bearings are suggested. They have proven to be of superior quality and design. They are tried and true. Lube the new cam bearings with clean motor oil or assembly lube and begin pressing into position with the specialty tool.

As soon as more resistance is felt, stop! Do not continue to reef on the tool. Doing so will result in damage to the crankcase or damage to the new cam bearings.
