Help! Trying to change a tire on my D14

Well, I've come again to the guys who've done everything AC!  You guys always give me the best help around.

I've got a 1957 D14.  The rim finally rusted out on my back wheel.  So I got a new rim, but I can't even get the wheel off the tractor.  First we were going to leave the inner wheel on the tractor and just remove the rim (it has the power adjust rims).  But we ran into several issues.  First off, I removed the 8 bolts that hold the rectangular mounting pieces (that bridge between the wheel and the rim) to the wheel.  The tire-rim system wouldn't come off.  I think that maybe I have to loosen the retaining bolts that hold the tire in one place along the rails on the rim?  But I couldn't loosen those, impact gun and everything.  So I finally decided to take the whole wheel and everything off.  So I removed the 8 bolts that hold the wheel to the hub.  The whole thing still won't come off.  Do I need to remove the center cap that's in the middle of the wheel?  If so, how?  Do I need a special tool?

If you guys can give me help on any of these steps, I'd really appreciate it.  I know my descriptions aren't the greatest, and unfortunately, I couldn't find a great picture to clarify things.  Thanks guys!

I hate to sound so stupid, but what should I pound on?  Does that center cap really hold the wheel on, or do we just pound till it comes off?!?

In that case Darrel, I'll just start pounding!  Thanks for the help!  I really like your avatar!

Use a big pry bar from back to pry between final drive and wheel while beating on inner wheel around bolt patteron. Leve one in loose to keep wheel from falling on you when it cimes loose.   MACK

If you can make yourself wait.....mix up the 50/50 acetone/dexron and soak everything that needs to come apart for a day. Even the hub center.The stuff really makes a difference.

I agree with all the above posts, reminds me of when I was younger and worked for a contractor. Me and another guy were given job to put new rails (tracks) on a D-8 dozer, the shop had a fixture to hold a big punch to drive out the master pins, well after spending couple hours pownding with a 10# sledge the forman went and got a 30# sledge and the carpenter forman happened to stop in-- he was a great big guy-- after about 3 hits the pin moved about 1/4 " us regular fellas were then able to finish getting it out.

I use a variation of Mack's method. Drive some wood between the final drive and wheel . this takes the slop in the bearings outward then hit the center of axle with the heaviest sledge you have, works everytime. Darned important to leave a loose bolt or two in the wheel for safety purposes.

I use a jack between the rims in the rear, or from the drawbar to the rim. I'm too old to swing a sledge too much. Bob

Carson, the best way that I have found is to have a High-Lift jack and put the rim under the draw bar and put the bottom of the jack on the tire very near the bead and the other part of the jack under the draw bar and just jack away.  It'll push the tire down and off, away from the edge of the rim.  You might have to spin the time 180 to drop both sides of the tire.  Works very well and is quite safe.

Go on a tractor ride. When you are depending on it to stay on, it will fall off.

When mounting be sure to WRITE DOWN which side it's for !!!

Take a photo before you take them off.   Look at the photo before you put them back on.

Clay and Chuck, thanks for the advice.  We used a 10' 4x6 as a lever and a piece of steel to ram down alongside the rim and break the bead.  Did it just this afternoon.  I hope we put it back on right.  Clay, I didn't see your post til after we got it done!  Chuck, the $100 is exactly the reason we did it ourselves!  Putting it back on the tractor is a good idea, have to try that when we go to mount it.

Thanks again to everyone on this forum who helped us along on this project!

First off if you are taking it to the tire shop, I wouldn't worry about it costing more. Just make sure that you talk to them about your plans ahead of time. Most understand and will make some kind of provision. We have one around here that will charge the total cost when they dismount them and put on invoice that it was already paid for the mounting. The other won't charge till you come back and mount them.
