Default Live axle convert to 1-wheel driven

I've been working on a live axle kart (Dingo), finally had a chance to drive it today. I'm not totally digging the live axle with both wheels locked to rotating axle... this thing is going to be on the street most (all) of the time, and it makes it more difficult to turn.

Can I just pull the key from one side, grease the axle/hub and run it like that? Thinking that the relative motion of the axle and un-driven wheel is very little... only when cornering, so maintaining a slick non-bearing surface would be enough. This falls apart if you start spinning the tires, but I don't see that happening unless it goes off-road. If it goes off-road, I can re-install key.

Thoughts? Potential problems? Do I need to fill the keyway(s) with something if I do this?

I wouldn't do that way. Gonna destroy the axle and wheel if you do it. Best thing to do would to would leave live axle and not wreck the kart. But of really want to do it I would use the old axle if u still have it and turn down end and put bearings in the wheel

I wouldn't necessarily say you would ruin the axle....(hub ....yes)....make that maybe.....but I wouldn't do it.....unless you want to roll the dice.....

There is always going to be some difference in rotation between the axle and hub ....sometimes minor....sometimes not...

So a better plan may be to get another hub with a bearing and an extra key....file the key down until its only slightly proud of the axle (very slightly) ....hopefully you have a collar on the inboard side...and can make a thin spacer for the nut...(so it only contacts the inner race of the bearing)...

That way the bearing will turn but not the inner race....when you install the key...you should still be able to push and pull the wheel off....you just want slight resistance....

Just my two cents.....

if i still had my old axle i would have just shipped it to you. when i bought the kart the po said they lost the key so the just rode without, when i took wheel off it was unusable and the axle was wrecked. the constant rubbing would like sand paper and kept wearing down the metal of both parties.

No doubt.....BUT!!! The big question is did he grease it? And how long and hard did he run it?

I say go for it. If you grease it and check it regularly. Obviously it is going to have more wear than not but... In my opinion, Considering the work I have seen You do to this kart. A new axle is like 22 bucks at BMI and a steel wheel is 17. So run it with the parts you have and enjoy. If these parts get destroyed they are cheap to replace or at that point you can spend the money on doing a correct dead axle.
Anyway if you convert it to a dead axle today your current axle and wheel are no good to you anyway. My only concern is didn't you have some nice classic wheels? would not want to destroy one of those.

Rear wheels are both new; they match what they replaced which was nothing special. Old ones were completely rotted out.

Feedbacks what I expected. I will play with it and see how it works both ways. I think there's some more to be had from the front steering first anyway. Next project tho will be getting variator added.

as long as there is grease in there it should be fine. I wouldnt fill the keyway with anything that could cause problems. If youve got the tools you could drill and tap the hub close to the center and put a grease fitting in there so you can add a pump occasionally

I considered that when I replaced the axle. Issue is it only comes in 1 width... 44 inches. A bit too wide for my cart; you can have them re-machined but adds to cost.
