Nut DIN 985 - M 14 x 1.5 - 8

Nylok-style nut used as the rear wheel axle nut, as the nut to hold the output flange of the gearbox in place, and on the bolts at the top and bottom of the sidecar props.

Takes a 22 mm wrench or socket. For the gearbox application, you'll need to modify a 22 mm socket by grinding it into a conical shape, to clear the inside of the output yoke. If you've ever fiddled with the swingarm of a BMW Airhead, you've probably already got the right tool in the drawer.
