About This Product
This Jims left-side mainshaft bearing is a critical internal component for early 5-speed transmissions. It is designed to fit 1980 to early 1984 FLT Touring and FXR models. As a direct replacement for OEM part number 8978, this bearing is built to handle the heavy loads and high speeds of a Big Twin drivetrain. Jims is well-known in the industry for producing some of the highest quality transmission parts available, and this bearing is no exception. Replacing a worn mainshaft bearing with this Jims unit will help restore the quiet, smooth operation of your classic Harley-Davidson's gearbox.
Manufacturer part number: 8978.
