How to Replace a Hoyt Z3 Cam

Hoyt compound bows, like all compound bows, use a series of pulleys and cams to actuate the string and release. The cams are the round internal cylinders of the pulleys and are essential for the mechanical advantage a compound bow uses for the draw back and pressured release. Hoyt designs its bows to be accessible for the layperson to do repairs such as cam replacement or maintenance with a minimum of tools and know how.
