J B Weld wheel repair

[PeterK]

Even if it holds air, my concern would be the strength of a rusted out rim on a tractor. Not something I would use as the strength of the wheel is already compromised from rust through and that wheel looks like it would buckle if given the opportunity.

We will find out if it buckles or not.
I might agree with you if it were a 4x4 and / or a FEL but the whole tractor only weighs in at 2500 lbs not counting extra weights or ballast.
I hope I am right anyway. I appreciate your perspective and opinion. That is why I'm here.
Thanks,

If it was a 4wd I would have done something a little more professional.

are the centers intact? if you have good donor rims and good centers. then it is just cut n paste...

Interesting patch job.

I assume you are running tubes in the tires. So, it doesn't really have to be airtight, it just has to hold the tube in place, not fall apart, and not damage the tube. I still might have brazed it all in place, but the JB might hold.

What I've decided to do on my Toro (not completed yet).

One of the rears was rusted out, and the other was in pretty bad shape.
I needed a pair of wide 12" wheels.

I found a set of Yellow 12" rims (I'll have to repaint to a more pleasing color) with a very large bolt circle.

I'll cut an adapter plate out of 1/2" plate steel (which will also give me some wheel weight, as well as improving the offset, I think). Anyway, my plan is to make rim bolt pattern adapters to match what I need. The Toro bolts should fit just inside of hub circle on the yellow rim. I guess many rims are designed to sit on a hub for additional stability, although I suppose I could carefully machine the adapter to fit against the rim for stability, perhaps in conjnction with

As far as relatively narrow 15" wheels.
The VW bug had 15" wheels with a large bolt pattern circle.

By the way a JD 870 2wd uses a 3x15 rim. It seems to be a popular size. Just the center section is the challenge. My brother had some steel wheels made for his car. If you have the good center then welding a good outer should not be a problem for a qualified welder. Or a shop that has a cnc plasma cutter can make a center. But I am sure the repair you did will work for a while. Just keep new used wheels on your shopping list and some will pop up sometime.

there ya go. 3x15 rims. that and the oe centers and it's an easy cut n weld job..

Assuming this is personal, on the farm use, I'd just use what he has, and see how it works.

One of the narrowest Auto rims would be from spare tires. I believe one of the most common sizes is 125/70R15. I'm not sure of the rim width, but probably about 4", or perhaps 4.5".

There may be narrower rims for the dragster market, but the spare tires above should be dirt cheap (about $5 each).

Anyway, you could cut new centers with a bit of lathe and mill work, although the size is probably a bit big for many home style lathes.

However, again, just see how the repairs above hold up. Unfortunately much of the work is internal, but one might be able to look for cracking around the valve.

Ahhh
Looks like you can buy new-fab rims.

Custom rim fabrication may also be available from other suppliers too.

Welding your centers onto blanks should be easy enough. Or, perhaps you could either get one of the manufacturers to fab up some custom rims (with any luck, they would be interested in custom sizes), or a local shop to do it.

it's REAL common to buy blank rims and weld in your own centers. many places sell blank rims jsut for that purpose..

On my tractor, one front rim the guy who had it before me bronze brazed the old hole and drilled a new valve stem hole. Make sure you deburr and smooth your new hole because if its at all rough you will wear through you valve stem on the tube. I also would make sure you have no rough edges on your patch, or that could cause problems with tube when you air it up.

$50 rim blank ... Now that is looking like a possibility right there. Great find. Thanks.
I think that my patch will hold but that is a great back-up plan.

Excellent advice on the new drill out hole. I did my best smoothing it over, likewise with the patch, I gave it a fighting chance.
That's why I didn't want to weld it myself. My welder is not gas assisted and I splatter a lot.
