Description
Accurate cam gear measurement is critical for proper engine timing and performance. The ANDREWS .108″ Gage Pins are the industry-standard precision tools for measuring cam drive gear outside diameters on 1990 and later Harley-Davidson engines. If you’re rebuilding a cam chest, verifying OEM specifications, or diagnosing gear wear, these pins eliminate guesswork and ensure your measurements align with factory service manual standards.
Note: These .108″ pins are specifically designed for 1990-1999 cam gears. Earlier model years (1984-1989) require .105″ pins. Due to gear diameter reductions introduced in 1992, always verify your engine year and consult your H-D service manual before purchasing.
