Description

S&SS&S, 54-E77 B.T. pinion shaft gear kit. Yellow  531956

fits  54-65 Panhead; 66-E77 Shovelhead (NU)

Yellow color coded for size. Complete kit for scratch builds or rebuilds. Complete with all components on the pinion shaft. Note: Kit must be used with a 73-99 B.T. style oil pump driven gear (S&S 531209 / OEM 26345-73). Note: 54-E77 B.T. kit can be used in 54-72 engines to speed-up stock oil pump RPM by 25%, like is stock in the later 73-E77 B.T. models. Note: Available in 531954 White, smallest / 531955 Brown, 1-step larger than White / 531956 Yellow, 1-step larger than Brown. Note: If the stock gear is unmarked and the size is unknown or you are scratch building an engine and without gear, S&S recommend 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 will give a harmless clicking sound but to tight can cause a wining sound, binding and premature wear. Consult the factory service manual for information on optimum cam gear to pinion gear fit instructions before you order.
