35125-372 Outer bearing race, transmission mainshaft. +.002"

When rebuilding a classic 4-speed transmission, you often find that the bearing bore in the case has worn slightly over time. This JIMS outer bearing race is oversized by +.002 inches to compensate for such wear, ensuring a proper press fit. It is designed for the transmission mainshaft on late 1937 to early 1977 4-speed Big Twin models. This race is for the main drive gear on the left side and uses loose roller bearings. While the standard size is 2.314 inches OD, this oversized version provides the extra material needed for a secure installation. It serves as a high-quality alternative to the standard OEM 35125-37 or 2284-37 components.
