If the stock gear is unmarked and the size is unknown or you are scratch building an engine and have no gear, we recommend that you order a gear in the middle of the size range These sizes were used more often and should provide adequate gear clearance under most circumstances When in doubt, use a gear from the middle to the small side of the range, because a combination of looser fitting smaller gears is less likely to cause binding and premature wear Consult the chart for the size and appropriate part number required If you wish to achieve optimum cam gear to pinion gear fit, consult your factory service manual for instructions on fitting these gears before making a selection Some sizes, particularly those on and near the ends of each range, are available on a limited basis because they are the extremes High quality S&S pinion gears are carefully machined, heat treated and then finish ground Three distinct year groups, in up to eight different color coded sizes for optimum gear lash, are available for big twin engines S&S color codes match Harley-Davidson® color codes so that replacement is easy Just pick the appropriate color S&S gear that matches the color on the damaged stock gear (see notes)
