S&S, 90-99 B.T. conversion kit sprocket. Red

Red colour coded for average size. Factory replacement for all 77-89 B.T. models. Used as a conversion kit on 90-99 Evo B.T. models with a pre-1990 pinion shaft. For 1989 and earlier style pinion shafts used on 90-99 Evo B.T. models (engines using S&S flywheels or other multi-piece flywheel assemblies), S&S offers this conversion package. The kits include a 77-89 colour-coded pinion gear, 54-89 oil pump drive gear, 54-89 shaft spacer and 54-89 shaft nut.
Note: see: 531306 Black (smaller), 531308 Blue (average), 904148 Red (average), 531309 Yellow (larger).
Note: All kits must be used with a 73-99 B.T. style oil pump drive sprocket (S&S 531209 / OEM 26345-73).
Note: If the factory pinion is unmarked and the size is unknown, or if you are building an engine from scratch with no pinion, S&S recommends a pinion from the middle of the size range. These sizes were used most frequently and should provide proper pinion play in most circumstances. When in doubt, use a pinion from the middle to the small end of the range, as a combination of smaller pinions with a looser fit will produce a harmless clicking sound, but too tight a fit can cause a screeching sound, binding and premature wear. Consult the factory service manual for information on optimal fit instructions between the cam pinion and shaft pinion before ordering.
