valve stems on H rear rims

c1802362 · May 20, 2014

The air valve on one of the rear rims on my '41H broke a few days ago. While fishing out the remaining parts from the stem, I began wondering if this is the way Farmall meant it to be...

Specifically, both of my rear wheels have valve stems protruding from the rims. One appears to be a bolted arrangement, while the other (the one with the broken valve) is welded onto the rim (a poor weld job to be sure).

My current setup suggests the tires are acutally sealing on the rim - there's no inner tube as far as I can tell. Shouldn"t there always be a tube? What is everyone else"s H's (and M's for that matter)?

The weld job is nasty on my one rim - I'd just as soon grind everything off and put a tube in.

Comments?

How's the rest of the rim look? I have done this to make a tire unless when the rim was to rough for a tube to not rub but was still structurally sound.

Mine has tubes but there are still nuts on the valve stems.

I think I have tubes. In the back of my mind, I think I had a hard time finding the nut that tightens down on that stem. Or maybe it was the little valve inside the stem that was hard to find. Finally found whatever it was at friendly tire place. Thought at the time it must be rare.

I didn't know anyone ever used tubeless tires on an H or M tractor. I am surprised that you could get a tubeless tire to seal on those old rims. I have only used tube tires on my tractors. Roger

Am I embarrassed!

Tonight I went out to the barn and took a good long look at the rim. I looked closely at the bad weld patch, then thought to check it with a magnet. Sure enough, the rim is steel, but the "weld" is actually putty. When I chipped it off I realized it was covering a large hole in the rim next to the hole the tube stem comes through. I could see clear through to the tube.

It is obvious calcium was in the tube at some point and ate its way through the rim.

So, now I need to get the rim/tire off, the tube and tire dismounted, then blast the rim clean, weld in a real patch over the hole and repaint before getting a new tube.

Sorry to exercise everyone...

Well, here's where things stand:

Took the tire/rim to the tractor tire store.
Had them replace the tube/weld up the rim
When they gave me back the new tube/rim/tire, I noticed it was very heavy and the invoice said "refill"

So, I emptied as much of the calcium chloride they put in as I could. Is there any way to get the last gallon or so still in the tube, or do I have to replace the tube again if I want a totally dry tube?

(I'm being very OCD here)

There is no way to get every last drop out. As much as you can is perfectly fine but if you're OCD that last little bit of calcium solution will probably eat at you way more than it will ever eat away at the rim...

You should make the tire shop replace the tube. It was their mistake to load the tire. You actually should have realized when your lower intestines came squirting out from trying to lift the thing, that something was wrong, and questioned it when you were still there at the tire shop.

you are absolutely correct - I was too busy trying to get the tire back to the barn and mounted to think about things.

You are also correct about the little bit of fluid still in the tube (my wife calmed me down)

And yes, I've come to a compensatory arrangement with the tire place
