NOTES: 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 # 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 S&S® does not offer a replacement pinion shaft for 1990–’99 big twin engines that accepts a stock pinion gear, oil pump drive gear, gear spacer and pinion gear nut, because experience has shown that the design is not strong enough for performance applications For this reason, we recommend and sell only the pre–1990 style pinion shaft for big twins To make the change easier, S&S offers a conversion package consisting of a pinion gear, spacer, nut and oil pump drive gear for big twin engines
