Changing fluid-filled tires - how to drain the stuff out?

[murphy1244]

jack up tractor on the affected side just slightly off of the ground. Open valve stem and let it drain. then place it at 6 o'clock. At some point it will stop and you still have several gallons left depending on the size of the tire.

buy some aquarium or fuel line tubing that will just fit thru the valve stem opening with the valve stem removed, and placed at 6 o'clock. push tubing in until you feel it touch the inside bottom of the tire. Slide down a plastic valve cap that you have drilled a hole in the top of the cap that just will clear the tubing as you slide it down onto and screw onto the outside of valve stem. Make an adaptor to make the outside end of the tubing larger so that you may shoot pressurized air into the tubing with and air blowgun. The air will bubble up through the liquid and start to pressurize the tire.

Pressurize the tire to say 10 lbs or so. Remove the air pressure and the fluid will come shooting out your tubing from the air pressure now pressing down on the remaining liquid in the tire. Re-pressurize as necessary when the liquid stream stops or drips weakly from tire. This will probably get 99 percent of it.

James, do you have a photo of this thing you made?

It doesn't exist murph. It is a thought picture. But it will work. Sure it is not going to get the last puddle at the bottom of the tire, but the principal can work.

This is how all inventions begin, as just a thought picture. Then make a prototype, and then adjust to real world.

Sorry thought maybe you made up this Gizmo. Sounds like something I need.

Thats how I do it when I need to get it all out. I use air pressure the whole way tho. Pretty fast until the last part. The small tubing is slow and takes awhile on a big tire.

I don't think there is anything to patent

It is just using the idea of having air in the tire to push the fluid out thru the small tubing..

Another concept, is that say the fluid was Calcium Chloride, and you wanted to get it all out, get as much out as you can with this method, then induce more water back in the tire with your standard tire fill and burp valve, run the tractor tire for a bit and then drain the water all out and now the very small amount of water that remains will have only a trace amount of Calcium Chloride in it and the wheel and inside of tire will be pretty well washed down.

How about attaching an air hose and using the cheap vacuum pump from Harbor Freight? I need to get all the ballast out of the tube so I can put sealant in. Already got as much as the gravity method would drain, about 15 gals so far. Tire is a 11.2 X 28 on a 9N.

The pump can't handle liquids. If you put a liquid/air separator in between the tire and the pump it would work. You still can't get all of it out without dismounting the tire.
