My murray rebuild has been going OK until this weekend. The kart ran fine and then the chain came off. Then came off again. The axle does have a wobble. Maybe 1/4" and I believe this is causing the chain to jump. It is coming off in the direction of the wheel. It has a chain guide (I have it off) that will only affect the chain on the inside of the sprocket.

I can't find a matching axle...or one that might be close enough. I have searched all over the web.
41 5/8" long
3/4" diameter
1" threaded ends
5/8" nut
3/16" keyway

Any ideas? How much would a machine shop charge me to make one from scratch? I was told that if I tried to have this one straightened, it might bend back due to "memory".


Thoughts please...Thanks

Sorry, but I have to say it :useless:.

We need to see just how bad it is if you want an honest answer....

I did not think about changing the bearings to accommodate a 1" axle. I'm going to have to measure to see if that would fit.
I previous posts you mention new hubs? What part is consider the hub on the go kart?

I'll have pictures soon of the rebuild. I have to get them into photo bucket and figure it out from there.

I appreciate everyone's help. I found out that the hubs and integrated wheels are 3/4". I ordered the axle suggested by itsid
.
