S&S, pinion and final drive sprocket kit 54-E77 B.T. Yellow

Size-coded yellow. Complete kit for new builds or rebuilds. Includes all components on the pinion shaft.
Note: The kit must be used with the 73-99 B.T. style oil pump drive wheel (S&S 531209 / OEM 26345-73).
Note: The B.T. 54-E77 kit can be used on 54-72 engines to increase the oil pump RPM by 25%, the same as on the standard B.T. 73-E77 models.
Note: Available in 531954 White (the smallest), 531955 Brown (1 step larger than the White) and 531956 Yellow (1 step larger than the Brown).
Note: If the stock wheel is unmarked and the size is unknown, or if you are building an engine from scratch without a wheel, S&S recommends a mid-range size wheel. These sizes were used most frequently and should provide proper wheel play in most cases. When in doubt, use a wheel from the mid to small end of the range, as a combination of smaller wheels with a loose fit will produce a harmless clicking sound, whereas too tight a fit can cause a howling sound, binding and premature wear. Consult the factory service manual for information on optimal fit instructions between the cam wheel and pinion wheel before ordering.
