Gauge pins for measuring the outside diameter of cam drive gears. 🛠️
There are two basic differences between '90-'99 cam gear sizes and earlier years: the overall range of gear pin measurements was reduced in 1990 from .006" to .003". The large gears are the same size for both '84-'89 and '90-'99 (green and black color codes). Gear size measurements in the '90 H-D manual use .108" pins instead of .105" pins, producing approximately .012" larger readings when measured over .108" pins. For '92 engines, stock cam gears are interchangeable with earlier versions although outer diameters were reduced by .025".
