1110 Cam & pinion gear gauge pins .105"

These JIMS cam and pinion gear gauge pins feature a .105 inch diameter and are essential for checking the pitch diameters of your gears. They fit 1954 to 1989 Big Twin models and are used to ensure the mesh between the pinion and cam gears is within tolerance. Getting this fit right is critical; a loose fit often results in an annoying clicking noise, while a fit that is too tight can cause a whining sound and lead to premature gear tooth or bearing damage. By using these pins in conjunction with the sizing charts in your OEM service manual, you can ensure your valve train runs quietly and reliably for years to come.
