(Part No. HD-38361)
See Figure 3-105. Measure the gear diameter with a
micrometer over 0.108 in. (2.743 mm) diameter gauge pins
on opposite sides of the gear. The pins are of the proper size
to fit between the contacting surfaces of the gear teeth. Gear
diameter should be measured in at least two places 90°
apart. Use GAUGE PIN SET (Part No. HD-38361) when mea-
suring pinion and cam gear sizes.
