Never expected this, but my AC Model B has a flat tire. What is the process for repairing it? Do I need to remove the entire wheel? Does the rim separate from the wheel while the wheel stays in place on the tractor? Can someone steer me someplace where I can find step-by-step instructions? Instructions are not in the manuals and I never had to deal with this before now. I would prefer not to take the entire tractor to a shop and have them do the work. If possible, I would like to take the wheel or rim with tire in place and have them repair it. Thanks for your help.

if you are talking about a Model B Farm tractor.... the front rim/ tire is held on by 5 bolts, just like an automobile. Remove the bolts and the rim / tire comes off..

If your talking about the rear tire ... the center hub stays on the tractor. The tire / rim is help on by 4 bolts, 5/8 inch diameter .... there are 4 CLAMPS that wedge the rim to the hub... Jack the tire 1 inch off the ground and remove the 4 bolts / nuts/ clamps and the rim / tire will come off..

If it’s the same as my brothers ib than it’s just 5 bolts (I think a 5/8” wrench) and the rim will be removed.
steve(ill) I think we just posted at the same time…. Ha ha

Sorry I didn't specify. It's the rear tire. Appears to be an issue with the tube or valve stem. In either case, the tire may have to come off in order to repair unless I can leave the tire on the rim; take one side off the rim in order to remove the tube and replace or repair it.

It will be easier for them if it's mounted to the tractor

You have to break the bead on BOTH SIDES, to move the tire on the rim far enough to get the tube out... Normally you will REMOVE the tire and clean / inspect the rim , then reinstall ONE SIDE of the tire, install the new TUBE and then pop the other side of the tire over the rim.... as i said above, just take the 4 clamps off and load the tire up in the truck and take to the TIRE GUY...

I’ve done (and plenty more to go) dozens of rear tractor tires, and only did one on a tractor. An A-C B rear tire is small enough to handle by hand so in my case it’s easier to remove the rim and all so I can move, flip around, and break the bead.
