Muncie Wrench M20 M21 and M22 4-speed models.
The Muncie 4-speed transmission will be around for many years to come. Be prepared for the next one you get to play with! Made of heavy duty precision-cut steel, our Muncie wrench easily removes and installs the thin-walled input shaft retaining nut. As an added feature, we cut a rounded-rectangular hole into the handle shaped specifically to operate the forks after the assembly process.
