Rear hub problems

[lilchas]

--------------------------------------------------------------------------------

Built a low profile cooler racer kart with wide 12"wide slicks tires in rear. After setting up live 1" axle with the 2 lightweight 3 stud alum. hubs , I found that both fixed hubs would not work, too much drag and kart would not turn well . My question is I want to have 1 hub free spining held by split collers but i,m concerned about the alum. hub wearing on the shaft . Will that be o.k. since they dont make a hub with a 1" bearing inside. Thanks.

I think what you are saying is that you don't like pozi. So here is a differential that will help your problem.

Also it won't be "ok" not using bearings. The one wheel drive idea isn't that great of an idea, you'll find that you will be much happier with pozi instead of one wheel drive.

EagleTalons solution might be the best way to go.

If you still want to try this, I was thinking you could buy 1 rear hub made to fit those huge 50-mm. race kart axles, and then have a machine shop mod the hub to install 1" ID bearings... (It would basically end up being just like a front wheel hub, but sized for 1")

They use these "ratchet" or sprag clutch hubs type hubs on the outside wheels in quarter midget racing but they only turn left

Try one on each wheel, but you better have front wheel brakes lol

On that Northern diffy axle, will it still operate as designed if the sprocket and brake were not mounted to the center section? I realize the keyway would have to be extended to place the sprocket where I'd need it, but I can't put the drum brake and drive sprocket in the center.

Just starting the rebuilding of the Dart Super K as a grandkid's fun kart, but I'm sure turning will pose a challenge so any input will be helpful.

Are you using a jack shaft, if so you can install the brakes on it.

So with this northern tool differential I would have to extend key way to fit sprocket and brake disc since slot is not long enough , don,t need threaded ends ,and key both of my existing alum. hubs to the shaft ?
