Jackshaft

[Sean B.]

Having some difficulty with jackshaft ratio. I have a 10 tooth clutch and a 38 tooth axel sprocket , nothing on the jackshaft yet. I have 14'' tires, any jackshaft sprocket suggestions ?

Depending on the size of shaft used, one could use a 10-20-12-38, or a 10-24-12-38 combo's for a good start...

Here's a calc...

Thanks for the info. and the calculator site. It has a 3/4 shaft.

According to the calculator With a 20 tooth sprocket it is 6.333 and a 24 is 7.600, are these calculations more for speed or torque. Don't need it to be fast.
