Another high precision tool from Jims. Designed to index the cam gear's position while removing or installing the cam gear on cam shafts used in 1970 thru 1999 single cam Big Twins. When the cam gear is removed, the gear can be repositioned to another camshaft in exactly the same spot. It is also possible to press the gear on in the advanced or retarded position. Easy to use, time saving and accurate. Use ZPN741904 to remove.
