9-Tooth Jackshaft Sprocket for #40/#41/420 Chain (5/8″ Bore)

Description

This 9 tooth jackshaft sprocket is used with size #40, #41, and 420 chains. It uses the common 5/8″ bore (inside) diameter that matches up to the 5/8″ axle shafts on many popular mini bike and go-kart models. In addition, this jackshaft sprocket is rather useful to the custom go-kart or mini bike builder who wants to design and assemble their own unique machine.
Categorized as a Type C sprocket, the 5/8″ thick hub is centered equally on both sides. (Type B sprockets have the hub offset to one side.) In addition, the shaft key is an integral (or “broached”) part of the sprocket.
Note: This jackshaft sprocket is not compatible with the Baja & Falcon mini bikes. These brands use sprockets with a slightly larger 0.675″ internal diameter.
