Transmission Mainshaft Wrench Adaptor

This tool fits the 1 7/8" nut that locks down your final drive sprocket on the transmission of a 1936-1984 Harley-Davidson (Knucklehead, Panhead, Shovelhead).

It is a travel friendly alternative to carrying around a giant socket, but still utilizes a 3/8" drive so you can use a ratcheting wrench.  It is cut out of 1/4" Stainless Steel.

As with everything we do, it is made in the USA.
