About This Product
S&S pinion shaft bearing. Sold as a set. Blue colour code. Replaces OEM 24643-87A. It is the late-style right-side crankcase bearing. Fits 1987 to 1999 Big Twin models, excluding Twin Cams. It is a direct fit for later Evos. You can adapt it to 1958 to 1986 Big Twins with pinion shaft spacers to centre it in the race. Using it with 1958 to 1986 flywheels can cause axial clearance issues. Check your tolerances during assembly.
Manufacturer part number: 31-4018.
