Zipper’s Twin Cam® Cam Clearance Tool

Use this tool to provide clearance for high lift cam lobes in ‘99-’06 Twin Cam® engines. This tool will quickly machine precision cuts on the pinion bearing boss and the tappet bore housing undersides of the case. Single-spindle tool machines front or rear cam clearance separately; to reduce set-up time choose the dual spindle model. Can be used on the engine case in the frame with a 1/2” drill or in a milling machine with a disassembled engine.

2007 and later engines would require a collar for inner cam bearing bore to support the tool. Zipper’s does not sell a collar
