About This Product

This is an MCS 25-tooth oil pump driven gear. It fits 1939 to 1972 Big Twin engines. It replaces OEM 26345-39. The keyhole measures roughly 0.93 inches for a 0.94-inch key. You may need to dress the keyway before installation. It drives the oil pump on Knucklehead, Panhead, and Shovelhead motors. Check the shaft for burrs first.

Manufacturer part number: 990520.
