B wheel question

I let my neighbor borrow my 54 B for a church function this past weekend, unfortunately the rear wheel came off as they were unloading the tractor off the trailer. I made an emergency trip to put the wheel back on but I noticed the raised areas (help me with terminology) where the 4 lugs (bolted to the hub) grab on to are worn down fairly low. My question is how have others repaired these raised areas inside the wheel? Seems like to me I could build them up by making a couple of passes with the welder or maybe weld some solid steel rod in place. I want the fix to look as close to factory as possible yet control cost. Also, most of my lugs (again help with terminology) are in good shape with the exception of a couple that have worn on the sides. Lastly, I noticed a couple of the bolts have decent wear on them as well.

Thanks for the help!

Case, are you familiar with how the eccentric bolts are positioned and work to tighten up the wheel?  I'm not trying to be overly basic here, but the "couple of worn bolts" comments made me think that you may be describing the eccentric bolts.  I can send you a .pdf file from the operator manual tomorrow, if you need more info.

Case and Ryan, I'm am not in a position to know whether it's a matter of wear on the rim or positioning the eccentrics, but I have had the same problem on my '41 B. I have had to build up the ridges on the rims as well as the stop blocks.   Bob@allisdowneast

Okay, I took a picture instead.  Are you following this procedure to mount and tighten your wheels?

This could explain part of my problem, I didn't pay attention to the position of the eccentric bolts vs the stationary ones. All I focused on was finding a clamp that would fit between the two square steel blocks welded to the wheel (I think they are to keep the wheel from spinning off the clamps). I will remove the wheels once again and follow the steps from the manual before I start any welding and grinding.

I had a worn out hub in both centers on mine and some rust under the rim eccentrics that made them a bit loose. 

I made shim plates from brass to go in the vee under two of the rim clamps on each wheel  (90 degrees apart)  You can't even see em when installed.  Eventually if rusty rim is the issue you just have to pull them tires off and get that stopped with good paint.  A hole rusted in the rim makes a real expensive fix.  Two of my three tractors need some work in that area.  A common issue on old tractors.

I also did some shims on the center splines of the B to tighten them.  Took about a year of experimenting with different fixes to make the rims stop 'popping' when I turned, they had been let go pretty bad.

Case- do a Craigslist search. there are several guys in the Raleigh area with tractors being parted out. 

there's a cross on the head of the excentric bolt to let you know what direction the excentric is, so you don't go past the high spot when tightening. when tightening the nut make sure the bolt didn't turn also.
