This is a new CNC machined rear miter box output shaft for a 2 wheel drive Rokon motorcycle. This is the shaft that connects to the override clutch inside the main frame tube. This works with the original unlocked override clutches. The shaft is 5 5/8 inches long. 2 new 3/16 inch diameter split pins are included. This will not work in a “Plunger” transmission or a front miter box. This shaft is keyed for the miter gear. The A1137 is no longer supplied with a snap ring or snap ring groove. an A1182 #108 miter box spacer can be used to replace the spacer and snap ring if required.
