Loose NH Baler Wheel Spindle

I recently purchased a pair of NH 273 balers. I was told that the PO had trouble keeping lug bolts in the one wheel hub. It turns out, that's because the wheel is cracked. After digging a little deeper, I found that the spindle has about 1/8" of slop where it goes into the axle tube. Has anyone ever had this happen? How did you repair this? My thought is that the bolt holding the spindle to the tube has some wear/slop to it. I plan to replace the bolt, if no improvement just weld the spindle to the tube... The bolt location has red arrows on the parts diagram.

Hopefully someone can answer this. I have a NH 315 and I can jack it up, tighten that bolt, then tow it to the field. With in a couple feet the wheel is leaning in again and appears loose. Tried a new bolt no help. Seem like a poor design, maybe 2 bolts would have been better?
 
If the bolt fits loose drill it one size bigger to get proper fit. Either way use a grade 8 bolt.
 
I agree that it is a poor design. I figured that the spindle was welded to an internal tube assembly. Like a internal rectangular tube to fit inside the axle tube... Not just a spindle shoved in a hole...
 
Grandpa, sounds like something about the axle tube is wallowed out or machined wrong.

The design is to make changing the spindle easier without needing to cut the weld. It also keeps heat off the spindle which could cause it to be brittle.

Going with 2 bolts would weaken the spindle.

I would look into repairing the axle tube, weld a collar on the end to correct the alignment, or weld collars over the bolt hole to relocate it to the correct position.
 
the cracked wheel is a result from the plowing of the wheel being out of plumb. Could you shim it with tin stock to tighten it up ?,,. Is the reveal the same all the way around or just wear spots ? perhaps the stud axle broke and it was replaced by something that was too small ?, i put a perfect size auger stud axle in my 268. works fine , i could have put a stud axle that was 1/8 inch smaller that the local farm store had on hand. but chose to rob a auger i want to repair so i could avoid a problem like yours ..
 
It did not seem to be worn unevenly (not slotted). The hole is just slightly larger than the spindle. I may swap the spindle out from the other baler and see if that closes the gap. I don't think shim stock will work as it won't stay in place permanently.
 
The bolt broke on mine once, that was kind a odd looking deal, until I figured out what was wrong.

Never been any other bother.

We had an old New Idea spreader that did that, was held the same way. The hole where the spindle slides in wears then lets the bolt carry the weight sort of. Get a piece of 1/4 inch plate with a hole to fit the spindle then weld it to the baler axle frame with the spindle back in alignment. problem wil be solved. That is what we did on the old spreader. That was 30 years ago. We still have the spreader used as a wood trailer now.

If it was a tube, inevitably the axle would rust solid inside the tube, making it impossible to change without lots of heating, beating, a porta-power, and eventually a tractor and chain to jerk it out of there.
