Need Help Pulling off rear wheels on a JD B

Hi guys! I have a 51 B and the RR tire is flat (ran over something - AARRGHH!) and my question is can I take off the rear outer rim with out pulling the center hub off? My center hub as not been moved in 30 years and I am afraid I will not be able to budge it. I have the rear rim loose but can not seem to get over the center hub, hoping someone has a trick up their sleeve. Merry Christmas to all
 
Yes, turn the cast wheel so the notch is on top, drop the rim in the notch and give it a half turn and it will fall off. If it is loaded with calcium you better have help.
 
Not if you need to take it to town. And if the person knew how to repair his own he wouldn't be asking how to get it off. I do not recommend tire repair to untrained persons. Sure it's not that hard but if you don't know how bad things can happen
 
Did you ask over on the JD boards?i had a b but its been too many years ago.generally the center hub will break loose fairly easily in my experience. like i say its been several years but i dont recall ever having one not loosen. is this the one with a sort of hump in middle of wheel and wheel clamps that bolt with one bolt to center hub? if so ,i always took all the clamps completly off,and the if you got wheel just right it would come around rim.
 
Your best bet is not removing the rim from the tractor. Jack up the tire, locate the breaker notch on the tire, and break your beads. Then it's just a couple of tire irons and the whole tire will literally fall off. Rinse the rim off good, and remouunt the new tire.
 
I used to take the rim off the cast center, lay it down and drive on it with another tractor to break the bead. Then remount on the cast center to take tire and tube off the rim. Oh to be young and able bodied again. Now I pump them up enough to load on the trailer and make a bee-line for the tire shop. Nebraska cowman has it right, notch on top, turn rim sideways as far as possible, drop in notch, rotate cast center and presto, it is off.
 
with air out of tire the rim will spring enough with a pry bat to slip over the cast center
 
I have a rear tire on one of my Allis' that I need to take off. "Drive over it with another tractor" is a great idea. I thought I was going to have to take it to FS. Thanks.
 

You understand, he is talking about that ONE good-sized Notch in the wheel Center..it will allow you to remove the rim..

All you are going to do is replace the rear tire and tube? Is the rim good? It is much easier to replace a rear tire when it on the tractor. Your problem then is to break the bead. I use some kind of "slammer" to get it away from the rim, then use tire irons. Once you get both sides loose, the rest is easy. You will have the weight of the tire to help you. A service call is about $100-150, might be worth it if you get nowhere, old tires can be hard to do.
 
Thank you all for the great advice! I will give it a shot this weekend. I talekd to my JD dealer who said if I bring it in, he will charge $50 - $75 to pop the old tire off, put a new tube in and put the new tire on for me. I thought it was worth that. I assume putting the rear rim and tire back on is just the reverse of the outlined process by Nebraska Cowman, right? Thank you again all
 
You are correct. Installation is the exact opposite of removal.

You do NOT want to take the whole wheel center off. It is VERY heavy and you would have no hope of moving it by hand or loading it in the truck. Two people can load a rim and tire as long as it is not filled with calcium chloride solution.

There are tire services who won't charge you much more than the JD dealer, and will come out and mount the tire for you, right on the tractor!
 
That is exactly what I do not want to do. I did not think about calling a service to see if they will come out to remove the tire, pop a new tube in and remount the tire. That would save me a boat load of time. The tries are not loaded with calcium chloride or I would have taken the whole tractor to the dealer and had them work on it. Thanks for the info!
