S&S, pinion gear L77-89. Red

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: 909084 Orange (biggest). Repl. 24040-78. 909085 White.
