Oliver 1755 Tire

UP Oliver · Nov 29, 2017

Hello:

I probably don't need to post this, but just want to make sure I am not going to do something damaging.

I have a leaky core housing on my 1755 that I want to replace, at least I think that is the problem. The tires are filled with fluid. I would think I can put a stable set of blocks under that flat metal that the axle(?) connects to and put my 20 ton bottle jack under there and lift the tire off the ground to get things done.

Is it that easy? Or do I need to lift the whole back end up?

Also, I would assume I can rotate the one tire when it is up in the air with the tractor in neutral?

Any help is appreciated.

Thanks.

Your plan needs wooden blocking under the axle after lifting the wheel. turning the wheel so the valve is on top will work. The wheel will turn in neutral. I rexommend blocking the front wheels and the ni=on lifted rear wheel to prevent rolling. Jim

If you're just replacing the core, you can do that without even lifting the tractor up. Just be somewhat quick about it (have the new one ready, and a few tools like pliers sitting there if needed) and swap it out. You'll lose a little fluid, but not much. Just wash it off with soap and water when done.

That's all the tire guy would do if we had him out for something else and had another with a leaky stem.

If you gotta do more than that, then yes you'll want to jack it up. Definitely have a heavy stand or cribbing to support it. Never trust a 10¢ o ring to hold, especially if your life or limb is on the line.

To the best of my knowledge (which isn't sayin' much!), I don't know of any tubes out there that you can replace the stem housing on. So this makes me ask, are you certain there's not a tube in the tire? If no tube, then should be a fairly easy fix, just as Jim and Don described.

I looked up and found a nice little video on how to change a valve stem without removing the tire from the rim. The guy goes into a good explanation of the tools needed (yes, special tools). For other videos, just go to Youtube and look up the phrase "[i:4502daabac]how to replace a valve stem without removing tire[/i:4502daabac]". However, things are explained quite well in this one:

I'm gonna GUESS this is what he is working with. There's an older style, as well.

All I would do is park the tractor with the valve stem at the top, take a pair of simple slip-joint pliers and loosen the housing. Hopefully once loose you can turn it out by hand. It won't start leaking until you get it almost out, like on the last thread. Like someone else said, have the new one in hand to install as soon as the old one comes out.

Tighten it up, hose off any leakage, and add a little air if you think you need to. Unless you really fumble around for a long time, you will not lose much air or fluid, and the tire certainly won't go flat.

Heck, you may not lose any fluid at all, depending on how full the tires are.

As others have said no need to jack it, but just for insurance, get the stem to the top, then block up to the drawbar support on the side that you are going to work on. I have jacked this way and it works well. You don't need to be out next to the wheel.

Under the axle is fine. The tire guy puts his under the sway block when he fixes tires for me. That gets it in farther so it's out of the way.

I'd jack it up with the valve at the top just in case things get out of control.Be very careful when breaking the core loose and don't twist the tube use small vice grips to hold the valve stem.Also be ready for what may come out could be you get a good dose of the fluid while trying to get the stem back in.There are two different core set ups on valve stems the older version and the newer style.

Thank you Bob! Was up most of the night brain-storming 'bout some things and thought I sorta remembered something along those lines, but the thought very much kept its distance! *lol* Have never worked on one of those before, though. Looks interesting.

Just guessing but will a tractor lift themselves up by the 3point hitch?

I believe that there have been a few built that have down pressure on the three point, but it is very rare. Ford had a jack available for the Ns which would raise the tractor when the lift was raised.

Thank you very much for all the responses.

I wondered if I could do the repair without jacking up the tractor, so thanks for the information on that. I got a two pack of the valve pictured by Bob from Tractor Supply, hopefully it works.

Thanks again.

Spent 22 years in the farm tire repairing business. Please jack up the tractor. That way if the fluid/air pressure blows the core housing out or your hand and you can't instantly find it-- you won't loose a whole lot of fluid. Speaking from experience here. The core housing shown is made for a tire without fluid. They make a Stainless Steel core housing for a tire with fluid in it. Good luck with your repair. If you can't find a SS one that one will work but will not last as long as Stainless. Usually the S.S. come with a S.S. valve core too.
