About This Product
When you're rebuilding the bottom end of an Evolution motor, you need parts you can trust. This blue-coded pinion shaft bearing from Sonnax is a high-quality replacement for the late-style right side crankcase bearing, specifically designed to fit 1987 to 1999 Big Twin models, excluding Twin Cams. It is a direct replacement for OEM 24643-87A. While it can be adapted to fit 1958 to 1986 Big Twins, you'll need to use pinion shaft spacers to center the assembly in the race, and you might run into axial clearance issues with early flywheels. For those older builds, we often recommend sticking with the stock style retainer and loose rollers if there's any doubt. This bearing is sold individually and ensures your crankcase stays tight and reliable.
Manufacturer part number: HDNB0021.
