inserts for loop on rear rims

[inairam]

I have to change out a tire on a 50s loboy. The rim had square head bolts. I thought the rim loop was clogged with dirt but the loops have 2 metal tab inserts.

I do not see this in the parts manuals. Has anyone seen these type of rims and know where to get the inserts?

Maybe posting a photo would help.

most of us don't know what you are talking about

This may not be why you have "inserts", but when I have needed to install or remove those "captured" square head bolts, the heads don't fit tightly in the loops, and I feared rounding off the corners of the heads. My solution was to use a large screwdriver jammed alongside one flat of the head, while I tightened or loosened the nut. This kept the head from rotating. Your inserts may be doing the same thing.

ok I should have waited until had photos to post.

I took off both rims as I did not have two turf tires mounted and had to use two ag tires I had mounted. I broke two square head bolts on both rims. The " good " tuft tire has one broken insert in what is otherwise a serviceable tire and a solid rim. The dry rot tire has 4 intact inserts and a solid rim

1) Where to get a replacement insert?
2) With the two tabs how to I get it in

Any idea how to save this tire and rim?

That insert is part of the loop. You may have to find a bad rim with a good loop you could remove and rivet to your rim.

on this rim it is a separate piece. it probably was inserted before the loop was rivited.

I doubt you can find the insert new. If you made or had new ones made, you'd still need to detach the loop to insert it and then rivet or weld back on to the rim.

Hi,
If it is not shown as a separate part in the parts manual, I think the part is not sold separately, and originally they just sell the whole rim as a replacement to fix it.

They have said on here the rims with 4 rivets per lug were made by Firestone. If the tire is off the rim, you should be able to read the info stamped on the inside of the rim.

That is a good idea Bill said above, find another rim and get the part from it.
You could buy a new rim, TM Tractor has them. They use different bolts to attach them to the wheel disc.

You could make a piece to fit, bevel the edges then weld it in the loop

It seems that piece is there just to keep the long bolt centered. So couldn't you use a square nut threaded to the center position on the bolt to do the same?

That piece actually holds the rim to the center. Without it the head of the bolt will pass completely through the loop.

Oops! DUH!

I just used longer bolts and thick flat washers to attach the rim to the tractor when that happened to me. Worked fine, and makes it easier on future generations because you can now put a wrench on the head of the bolt.

I don't think my tractor has inserts, or even a place for them. My rims are attached with carriage bolts (1/2" as I recall).
