Broken valve stem fixable?

I was out mowing our trails in the woods years ago and broke one off, I got out to the end of the county road but then it was too flat to drive on. So, I walked 3 miles back to the cabin, filled 2 air compressor tanks, put them in the truck, drove it back to the tractor. I aired the tire up using a rubber tipped blow nozzle and drove a wooden plug in it. This allowed me to drive it out to the garage at the cabin, where I broke the bead using a High-lift jack and 2 large wooden timbers. It is a tubeless tire so i just installed a new rubber valve stem, and it's been fine ever since.

Why would you not simply replace it? Cheap compared to hassle of a sketchy repair goes south and I'm not even sure hoow you would do anything other than a temp thing as Russ mentioned.

Didn’t really want to have to buy a new tube and have to break it down.was hoping someone had a idea

That is not a tubeless stem as some may think. With out seeing the missing part, I think you are going to need a tube. I would get a good quality tube from a tire shop that does these tires and not screw around putting a replacement stem on.

I don't see any threads inside the stem if it was the new style water fill stem and the hole it too large for the valve core housing to be broken off in it. That looks like the old-style water fill valve that had a core that slid in and was held by a collar cap to the external threads (about the size of a regular valve stem) on tube stem.

You have only one option ----- replace the tube or if it's tubeless replace the valve stem.

I feel Jim is right. Time to buy a good tube and replace it. None of us like to pay the cost of the more expensive tubes but in the end its the right thing to do

Look at TR218 or Milton S-462 for glue on valve stem. Slide new stem into place over a match stick so to center over old existing hole.

I’ll probably buy a new tube,just was hoping.got all individual weights on it to pull the tire and manhandle it.maybe I’ll get the tire guy to come right here and replace and refill it with calcium

Replacing the tube is the only option.
If you want to try and prevent this in the future adding value stem protectors while you have the tire broken down is something to consider.

My own fault,trying to use my tractor as a skidder

I had one get snapped off, fortunately mine still had a half inch or so sticking out.
Tubed and calcium filled.
I ran a thread die over what was left then screwed on a brass 90 degree fitting with some Teflon tape.
Into the brass 90 I screwed a Schreader valve from an old well pressure tank.
This was meant to be a temporary fix so I could finish feeding the cows one weekend.
Six years later it is still holding.

See if a 5/16” drill will fit in there. If it does, thread it to 1/8” NPT and screw in a air valve you can get from any hardware store..

See post #9, he posted he plans on having it refilled with liquid ballast. It can be done but a small stem won't be very handy for that.

Not that big a deal. I’ve filled many 16” tires in a few minutes time. I would guess a 16.9-24 would take 20 minutes to half hour with a decent pump. A decent trade-off in time as opposed to the can of worms he’s liable to open when he breaks that tire down… just for the mess alone.

I know it can be done and it works for you, but it's not a method I'd recommend. From what he posted it sounded like he was going to have a tire shop do it. I doubt a shop will play that game. I'd say it all depends on if he does it himself.

Leave the tire mounted on the tractor. It's a lot easier that way, almost like having two extra hands.

By all means, that might be a good solution! If you can tap it 1/8 NPT, Schrader valves are available that will screw right in.

At the risk of being reprimanded again for offering friendly advice.......

I'd take the wheel off, load it in my truck, take it to the tire shop, tell them to fix it the proper way, go for a coffee, maybe two, go back to the tire shop, pay the man, load the wheel, go home and put the wheel back on.

Done, good and proper, no muss, no fuss, wash up, relax and have a piece of cake.

When I worked in a tire shop the we absolutely hated when someone would bring in a tractor rear for repair. Especially if it had chloride in it. They charged extra because it was harder to do off the tractor than on it. The extra charge often would have covered the cost of a service call.
