Unhappy Rusted Wheel repair on ZL 1500-A

Hi everyone. I have a very old ZL 1500-A that has served me well for a few years, but I haven't done a great job of protecting it from the elements. I recently had a front tire tube fail on me. I replaced it with a tube from TSC and it soon failed too. So, I figured I had a bigger issue.

I pulled both wheels and the tires and tubes. There was significant pitting on the inside. I figured the wheels deserved a good AL oxide blast in my cabinet followed by some primer and a new paint job (this time in orange on the outside not just the inside).

As I blasted around the hole for the tube valve stem, unfortunately it quickly grew. There was a lot of corrosion in this area. Looking online this seems fairly common and a recommended fix is welding in a washer. I'd like to do the same (I'll probably braze it) but now I'm not sure where I should center the hole in the washer.

Looking at some pics online it looks like I should center it in the vertical side portion of the wheel. I'm just concerned though that my replacement tube seems to have a stem coming out at about a 30 degree angle. It seems like that wouldn't be the correct angle unless the idea is that the stem settles lower down in the "bead" of the wheel when inflated.

Any guidance or perhaps pictures of similar repairs? Thanks in advance!

Not to sound like a smart a** but can you use the other side as a model to show you where to put the hole?

If not I would file the edge of the hole until you have some good meat to weld/braze the washer. Mount the tube and tire, while using a lot of baby powder, then place the washer over the stem of the tube. Using a marker trace the washer and break the tire down. Weld / braze as needed. A little paint and you should be good to go.

Good luck!

You might get a fender washer so you have a better chance of getting some good steel on the rim.

Both sides look equally bad, unfortunately. I did find some old pictures of the tractor however and the hole appears centered in the side of the rim.

Suggest you drill a new hole in the best area of the rim and just focus filling in the old hole.

There is nothing unique in the hole location on a low speed wheel.

Yep, I had a rusted out valve stem hole on my rear rim due to the calcium chloride; welded over the hole with a nice 4"x4" piece of plate, then drilled a hole in the plate for the stem. Or just drill elsewhere after you weld over it.

I had badly rusted out rims and wire-wheeled the area and filled with JB-Weld, then used a unibit to cut a new hole thru the JB Weld area. Itís lasted now for 18 years.
