0041422 Bearing assy, pinion shaft +.0004"

When rebuilding the bottom end of a 1937 to 1973 45 cubic inch Sidevalve, achieving the correct bearing clearance is paramount. This Samwel pinion shaft bearing assembly is oversized by +.0004", providing a solution for right side cases that need a tighter fit than standard. It serves as a direct replacement for OEM 24672-37. Using precision-sized bearings like this allows a mechanic to compensate for minor wear in the engine cases or on the pinion shaft itself. This ensures the rotating assembly remains stable and well-supported, which is essential for the longevity of these vintage Harley-Davidson engines.
