0229301 Retainer, oil seal mainshaft

Keeping the oil where it belongs is always a challenge on vintage gearboxes, and this mainshaft oil seal retainer is a vital part of that battle. Manufactured by Samwel, this reproduction piece is designed to fit 1941 to 1973 45" Flathead models. It serves as a direct replacement for OEM numbers 35219-41 and 2293-41. During a transmission rebuild, the original retainer is often distorted or corroded, making a fresh replacement necessary to ensure the mainshaft seal seats correctly. This part is built to original specifications, providing the correct fitment for the 750cc side-valve transmission. It is a straightforward, high-quality solution for mechanics looking to maintain the integrity of their classic Flathead's driveline.
