12-0424 Retainer, sprocket shaft rollers

This sprocket shaft roller retainer is a critical component for the left-side engine case on vintage Flatheads. Manufactured by Samwel, it is built to the exact specifications needed to maintain the integrity of your bottom end. It fits a wide range of 45" Sidevalve models from 1932 through 1973. Whether you are restoring a pre-war WL or keeping a later Servi-Car on the road, these retainers are vital for proper bearing function. Sold as a set, they replace the original factory part number 24720-29. Don't risk using worn-out originals when you can install fresh, reliable hardware during your next primary or crankcase service.
