This bearing replaces the worn element in the gearbox to limit axial and radial play that can cause noise, vibrations, or premature wear of the gears. Designed to fit into the transmission architectures of 1980s Harley-Davidson Big Twins, it is particularly suitable for Vintage/Classic projects and Touring machines where transmission reliability is paramount.
