Rear wheel leak/rust?

Postby HarveyCub » Wed May 06, 2015 1:57 pm

Hello all,

I seemed to have developed a nagging little problem recently with one of my rear wheels on my '66 Lo Boy. This is my first tractor and I've not had it a year, so everytime I visit the board, it's something brand new to me. Over the winter, I used the tractor for plowing quite a bit. After the last snow had gone, I noticed that one of the rear wheels seemed under inflated. I have some sort of liquid ballast in there (don't know exactly what, it was there when i bought it), so I got the tires to have the valve in the 12 o'clock position and added some air to the tires. This was all done by site as I have no idea what pressure I would be looking for on the gauge (first time I've ever worked with ballast filled tires). Everything seemed fine, and actually still does, with regard to inflation. The only oddity is now the left rear tire seems to leave a small puddle under the tractor (see attached image). Clean it up and it will come back by the next day.

As I noted, the tires still seem properly inflated and nothing burst or comes out other than a trickle. I don't believe that it is the valve itself, but perhaps something with the rim. Has anyone seen anything like this before? It only started after topping off the tires, so either something was a bit weak or I made a booboo.

Thanks,
HC

Possible it's calcium chloride and will be extremely corrosive to the wheel now that the tube is punctured. I let one go in our 57 and am now looking at having to replace the rim.

Fix that leak ASAP. It's probably calcium chloride and it will ruin the rim. Regardless of who does the work( you or the tire shop), make sure the rim and the inside of the tire get cleaned really well before re-mounting.

Until it's fixed, don't park near any vegetation you don't want to die.

Drain the Calcium Chloride (it kills grass and pets) and dispose of it. Take the tire off and check the rim, especially around the rim, for damage. Get a new tube and remount.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

Drain the fluid from both rims. Clean up the rims and tires, new tubes.

Echo all the above. We had to replace both rims on our H because of this stuff. Not cheap!

Tire pressure with or without fluid is the same. Make sure you have the valve at 12 o'clock (like you mentioned) when you check it. Not wanting to start the debate but this is reason #1 why I like wheel weights, they don't leak. :D

In the photo the leak appears to be on the inside of the rim and there is considerable rust.

Break down the tire and clean up the rim.

If it was mine, I would first determine where it is leaking. Calcium chloride does deteriorate the valve core and the housing for the core. On some tubes, replacing just those parts will restore the tube for some additional time. The rim is damaged and will continue to rust until it is cleaned up, perhaps welded up and ground to shape. Or it can be used until it really fails and must be replaced.
The fitting might be like this http://www.31inc.com/products/details/1596

If the tube is leaking inside the rim, removal and repair or replacement is necessary.

A number of choices for action do exist.
