My neighbor came to me last night with a problem. He just bought a JD 4430 that had duals he removed the duals and went to tryin to move the hind wheels. He cranked the wedge bolts out against the wedge and hit them with a hammer and broke the backs out of the wedge on both sides now he's stuck. I told him he would probably never get them out now. Does anybody have any suggestions he wants me to try and get them out for him but i don't know how to now.

I know this sounds crazy but it worked for me one time. If you cannot get them to break loose, Get the tractor out in the yard and away from everything. Jack up the side you are working on. Place in high gear, get the speed of the wheel up and stomp the wheel brake. I had one that I heated, beated, cussed, and repeated. The sevice manage at the dealer told me to do this and the first time it worked.

Using a tube cut out to beat against the wedge is the best idea. You may not need to cut half of it away though. If the main bolts are out of both wedges, you can beat on both at once if you leave the pipe the same length all the way around. You only need to cut the pipe out halfway if you just want to cocentrate on one wedge and leave the other in place. Give the whole area a good drenching with penetrating oil hours or days before you start. With the backs of the wedges gone, you can't put any steady pressure against them, which is what you need to knock them loose with smacks on the ends of the axle. He learned a good lesson - you never try to move the wedges with the forcing screws when they're completely tight - you'll either twist off the forcing screws or break the wedges 95% of the time. Use the screws to put some pressure on the wedge, smack the axle end a few times, tighten the screws agains slightly and smack again, etc. etc. etc. until they pop loose.

Find a piece of tubbing the size of the axle. Cut a notch in one end of it half way across. On the other end weld a heavy piece of flat iron then you put the notch on one wedge and hit it with a sledge hammer. Hope this helps. I have done it more than once.

I have had that problem. I used a piece of pipe about the diameter of the axle, 3 1/2 I think. Isplit it with a torch and made a half circle on the end so it would only contact one wedge and used it for a punch to knock out the wedge. After several hard licks with a sledge hammer it came out.

back wheels can be a pain, try to get a bottle jack on the back side of the wheel and push on the cast part of wheel close to the axel as posible, helps if their are loader brackets to push the jack aganst. then get the 8pound sledg and beat on end of axel, should work did one last week this way, it rilly went bang and jumped 6" when it broke loose, good luck

I had the very same thing happen to me years back on a 4230. I sprayed penitrating oil between the wedge and the hub and let it set for awhile. I used a big rose bud for heat, and a big punch and ten pound sledge.I beat the hell out of the wedge from the out side with the help of another person hold the drift punch. One wedge finally came loose, the next one was easy then. Oh by the way, I found out how spendy a new set of wedges are. I used anti seize on the new ones. good luck.
