Farmall F-12 rear tire tube change?

[AKdually]

I got the outer ring off and the new tire and tube in. Not able to get the one piece outer ring back on. Pops off when I get about two feet from having it on. Any clue?

The rim groove and the ring groove must be clean of rust and paint build up for them to lock together. I find it best to lay wheel flat on ground and stand on top of ring so it does not pop out when I am working on it. oldiron29

I am sure you probely know this, but when you air up the tire make sure you protect yourself with chains around the tire if you don't have a tire cage.

Try using some nylon ratchet straps to hold the ring in place while you work the last little bit onto the rim.

When airing up, I would also use a locking air chuck, and control the air with the valve on the air compressor from as far away as possible, rather than stand there and hold the chuck.

I assume you have the same rims I do on mine, I was able to pry on that little lock/clamp/whatever its called just enough to let the ring slip down far enough to get it on.
