I am trying to remove the (Heavy) cast iron RH rear wheel on my Farmall "A" tractor. I haven"t used heat and don"t want to if I can avoid it. I have put a lot of Blast penetrating fluid and a lot of WD40 and have tap-tap-tapped forever and it just won"t let go. Is there something I"m missing or need to do that I don"t see Does anyone have any suggestions?
 
Does the tractor run and drive?? If it does loosen up the bolts just a little bit and then drive it in a figure 8 and doing that should make it pop off. Just do not loosen to to much or you can brake the bolts/studs and end up with the tractor on its side
 
I'm not clear, so I'm not sure what to suggest.

If you've got the bolts out and she's not coming loose, best advice is a BIG hammer.

If it's the bolts not breaking loose, you shouldn't be afraid of heat or any of the usual remedies for frozen bolts. You[r'e not going to hurt that wheel any with the heat it takes to break a bolt loose. In fact, the threads the bolt goes into are on the hub, the end of the differential shaft. The idea with heat is to let things heat up and expand and break up the structure of the rust. I've had a lot of luck in similar situations with heating the bolt head (or the other end, if I could get to it) and then letting it cool down to where my penetrating oil of choice wouldn't just sizzle when I put it on, and letting it draw the oil in as it cools.

There's a gazillion thread on this, so the search engine here can be pretty frustrating, and I won't send tou there. But a common trick is to do the heat and penetrant thing and then try to actually try tightening the bolt before trying to loosen it. Rust is a crust. It's strong, but it doesn't take much to break it up.
 
My question may have been confusing. I have the weight,tire & rim and all of the bolts off with no problem. I can't get the wheel to break loose from the hub of the axle. I have beat on it a lot with a hammer but it won't budge.
 
You could try the bolt busting technique, and try to get some heat onto the hub, to break up the rust just by the heating ad cooling, and use wht I talked about earlier about letting things cool enought o draw in more penetrant when it cools below the point that it simply evaporates it. With that much iron bonded to the hub to sink the heat away, I shouldn't think that you'd ruin the temper of the hub or its shaft with the heat.

From what you describe, my best suggestions are patience and persistence. Don't forget to rotate them so that you're beating on different spots. They will come apart.
 
Yes that can be a problem. It is rusted fast. Some have put a chain across the cast wt then used a hy jack on the center and with the chain across the jack have busted them loose. I have used wd-40 or something likewise and tapping good to let the stuff soak in a little then used a huge mall going around the edge of the cast while rotating the cast have been able to get them loose. I would have two bolts in loose as that center weighs 147lbs and you sure dont want it poping off on your foot. Even the steel ones can be rusted bad. good luck
 
Getting hub off axle can be a problem. I've used a hydraulic jack to push them off. Also a big pry bar and a hammer. Also, look and see if there is a threaded hole on the inside of the axle flange. If so, you can thread a bolt into that and push against the hub to break it loose from the flange.
 
Thanks to Haas for the hydraulic jack idea. it worked great, I put a little tension on the hub using the jack and a chain, smacked it a few times with a hammer and, "POP", it came right off.
What a great service this forum provides. Amazing the knowledge that is available from so many enthusiasts.
