Use this tool to provide clearance for high lift cam lobes in ‘70-’99 single-cam Big Twin engines. This tool will quickly machine precision cuts on the pinion bearing boss of the case. Can be used on the engine case in the frame with a 1/2” drill or in a milling machine with a disassembled engine. This tool was developed to make quick work of case machining when installing a high lift cam in a Big Twin single cam case, 1970-1999. Bolts to the case, uses the inner cam bearing to support the cutter spindle, has adjustable cutter diameter and threaded depth feed for precise control of the cut. Can be used on an assembled engine and does a much cleaner, professional job than a die grinder. Power it with a half-inch drill, or use it on an unassembled case in a milling machine. Makes a job everyone hates a lot easier and cleaner.
