Note: All S&S pinion shaft gears are designed to be used with a 73-99 B.T. style 24T driven gear (OEM 26345-73 / MCS 531209 S&S). Color coding sequence is identical to stock H-D coding. When in doubt use a gear from the middle to the small side of the range. A combination of smaller gears should provide adequate gear clearance under most circumstances. Both excessive and zero gear lash combinations cause engine noise; but no gear lash causes binding and premature wear. Sizes are as follows: 915687 Orange (biggest). 909055 Black. 909060 Red. 909065 Blue (average). 909070 Green (average). Repl. 24010-54. 909075 White Repl. 24010-54. 909080 Brown (discontinued). 909081 Yellow (smallest).
