JD750 AG tire valve stem

[DeereDoug]

Today found that my valve stem was leaking fluid and air. How easy are they to obtain and repair? What would be the proper procedure?

For a permanent fix, you'll need to replace the valve stem (and tube if equipped) and repair the rusted out hole around the valve stem. This is a very common problem on tractors that have tires loaded with calcium chloride.

The usual method of repairing the rim is to cut out the bad area, clean things up, weld in a patch and drill a new hole for the valve stem at another place on the rim.

You'll likely find that much of the inside of the rim is very rusty. Calcium chloride (a salt) is VERY corrosive. Rim may possibly be beyond economical repair, depending on the price and availability of a replacement rim.

If repairable, it's best to aggressively clean the entire inside of the rim, prime and repaint.

you will not really find out what is going on. till you get the tire off the rim.

you might get lucky and just some surface rust, and all you need is a valve stem. but i might push for a tube, as a quick replacement using original hole that is there.

if you have say a 30 gallon sprayer, with on demand 12v pump on it. it might make your life easier. pumping fluid out of tire, and filling tire back up once you get things fixed.

you can pick a better "fluid filler" i want to say from "glempers?" spelling were you take inner core out of the valve stem and the little device screws right onto the valve stem.

Your pic looks a lot like my rear tires on my previous tractor. Calcium chloride is really bad news as far as corrosion. I would remove and tear down both tires and assess their condition. If the rims are salvageable - remove all the rust, prime & repaint. Then I would suggest using a fluid that is less corrosive. Windshield washer fluid, RV anti-freeze, Rim Guard etc. Mine got to the point where I was replacing the valve core annually.

My new tractor has Rim Guard and its not been a moments problem.

I am certain that whats leaking out is antifreeze, and I was wondering why it was rusted like that. Now I understand as to why, thanks.

Need to find someone locally that could come out and look at both.

you have a tube leaking

The previous owner installed antifreeze, today I was told that antifreeze attacks rubber and that is what ruined the valve stem. Needless to say, I prefer just air.

Wow! Don't tell the radiator hoses that!
