4 speed Tranny Test Nut

Have you ever rebuilt a 4 speed, and wished you could bench test it before you installed it back into the bike? Now you can!

This nut threads onto the mainshaft of a 4 speed trans, and allows you to attach a half-inch drill motor to it so the trans can be run. This allows you to be sure the shift forks are properly aligned, as well as test for leaks.
