2280 Cam bearing/bushing alignment test tool

Ensuring perfect alignment between the inner cam bearing and the outer cam bushing is vital for preventing premature wear and mechanical noise. This JIMS alignment test tool is specifically designed to check this relationship on 1970–1999 Big Twin models, excluding Twin Cams. If these two points are out of sync, it can lead to binding, heat buildup, and eventually, catastrophic cam failure. By using this precision gauge during the assembly process, you can verify that your crankcase and cam cover are perfectly matched. It is an essential diagnostic tool for any serious engine builder working on Shovelhead or Evolution powerplants, providing peace of mind that the valvetrain is perfectly aligned.
