Replacement parts

 Here you can get replacment parts for an engine you have purchased from CR Machine before, or you can get a precision balanced bottom end assembly and you can do your own cylinder work.

CR Machine engine cylinder bodies have identification writing on the top of the top cooling fin.

You will see the model and usually the stroke of the engine engraved on the top fin.
