If the gear shaft does not pass infront of the pinion use a dummy shaft for taking measurements. Mounting distance After the pinion is mounted the gear is located bysetting it to have the proper amount of backlash. Recommended gaging dimensions forlocating pinion from gear shaft to flaton front of teeth.Spacing collar is ground toproper thickness in assembly. Fig. 28 - Measuring or gaging as shown is the recommended method for locating the pinion. Pinion should be set to mounting distance marked on pinion, and gear should be adjusted to give correct backlash.Courtesy: The Gleason Works >
