I know this is an old thread. But I feel the need to share this information. Hope it helps someone.
Here is what I tried to remove a stuck wheel:
- soaked it with penetrating oil.
- ran it a year with no pin in the axle. no luck
- hammered on it.
- Pried on it.
- heated it.
- Pried, hammered and heated.
Here is what worked:
How to free a stuck wheel on a troy bilt horse.
Tools:
- Welder (any flavor)
- Impact driver
- Pneumatic drill
- Wire wheel
- Large socket
- compressor
Materials:
- Large nut and bolt.
- Penetrating oil
- paint
Spray the axle and hub of the rim liberally with penetrating oil.
Hammer and pry foolishly at the wheel for about an hour until you are completely frustrated.
Have a beer and think about how to do it right.
Wait overnight for the penetrating oil to go to work. I repeated this for the course of a year (not every night

).
I had the bolt laying around. It measures 0.9 x 14" I don't know the pitch. By chance that is about the diameter of the horse axle.
With the bolt as a guide weld the nut on the hub of the rim. Put down some material and spread the bead. I welded it with the tiller laying on its side and filled the well of the rim with water to keep everything cool. I drained and replaced the water as it became hot.
Thread the bolt into the nut and snug it up against the axle.
Put on the impact driver and thumped away for about a minute until the wheel comes off.
It moved so slowly I didn't think it was going to work.
Take an air drill, or electric for that matter, and clean the axle and hub with a wire wheel.
Leave the nut in place and paint the rim.
Total time:
- 5 minutes to weld.
- 1 minute to hammer the wheel off with the impact driver.
- 5 minutes to clean the axle and hub
- 5 minutes to clean and paint the rim
