Used to correct backlash (free play) between the cam gear (on the cam) and the pinion gear (the smaller drive gear).

To correct backlash you can either use smaller or larger pinion gears or smaller or larger Andrews cam gears. Note: See 503768 (. 108") and 503769 (. 105") cam gauge pins to measure cam
