35125-3710 Outer bearing race, transmission mainshaft. +.010"

For transmission cases with significant wear or those that have been bored out to clean up damage, this JIMS outer bearing race offers a +.010 inch oversize on the outside diameter. It is specifically designed for the transmission mainshaft on late 1937 to early 1977 4-speed Big Twin models. This race fits the main drive gear on the left side and is intended for use with loose roller bearings. By providing a larger 2.314-inch base diameter plus the .010-inch increase, JIMS ensures you can maintain a tight press fit in older 4-speed gearboxes. This part is a precision-engineered alternative to the standard OEM 35125-37 and 2284-37 races.
