Would anyone out there have an idea on getting a cast center off the axle that has had the wedge with the dials broke off on the end with nothing for the jack bolts to hit, rest of the wedge is under the cast center (the saddle part). Tried extreme heat, air over hydraulic 20 ton jack, 10 ton porta power, grinders, sledge hammer after heat. Found nothing that works. Tire and rim is off the tractor. Please help and thanks
 
Don"t know what tractor you have but on a JD I have a pipe that slips over the axle, when the axle is turned so the moveable wedge is on top. One end I cut at 45 deg, on half of that end. Leaves a half-moon that fits against the wedge. Other end, weld steel plate to whang on with BFH.
 
Thanks JMS for the info. I will certainly try it and I did forget to mention this job is on a JD 5020. I appreciate all the help.
 
I took a portable metal band saw to a hub on my MH 44. I could not budge it any other way. I sawed it up into pieces, it went remarkably fast.
 
I feel your pain. I went through the same thing on our 5020 several years ago. I still had the tabs to jack against. If I remember I made a stand to swing a heavy piece of steel against the axle. Protect the end. It took a few days (not steady) but I finally got the thing off. If you get thing seperated someone said to put wax paper on the wedge when putting it back together. Stan
 
I will pass out a WARNING!!

I built a thick walled pipe to fit the moving
wedge on a 3020.. I worked after about 2 hours
of Heat, & a 15 pound maul.. Of couse this was
after 2 or 3 weeks of blood sweat & tears.

Then about a week after the tractor was back
together I got the chance to remove the whole
wheel & tire again, because we Broke the race's
for the wheel bearing by beating on the axle
wegdes.. So Becareful on How hard you Hit it.
 
It sometimes helps to remove the bolts from the other wedge also. It is easier to slide both on the taper than one on the straight axle. Then hit the end of the axle with a large maul. Hit it like you are trying to drive the axle out of the wheel which is really what you are doing. The dead weight of the wheel will help jar the axle loose. You may want to inspect the bearings if you have used excessive heat plus the shock from hitting it. Good luck.
 
JD techs told me to beat on the axle. I think that"s likely to cause more damage than hitting the wedge. You"re not trying to move the axle. The wedge is stuck on the axle, not the other way around. Hit what is tight.
 
Thanks Cliff for the info. I removed all the bolts from both wedges before I started and the space behind the wheel is limited because I had to unbolt the 520 lb weight to be able to get the back three bolts for the other wedge. Trying ever so hard not to damage the bearing, race or seal in the axle housing because the ole 5020 is extremely heavy and would hate to break it down to repair it. I really appreciate all the help and info from everyone. Thanks again guys, Will
 
You are absolutely right. I haven't hit the axle yet and my plan was to work on the wedges not the axle. I plan on using the pipe you suggested over the axle to start with. I have a friend big enough and stout enough to cause something to happen. Thanks again JMS for the tips.
 
If you"re using the pipe by yourself, it saves some grief about maintaining location if you weld a nut on each side of the pipe, near the hitting end, and use tarp straps to the wheel to keep it in place, allowing continuous hammer hits. Use a pipe just big enough to fit over the axle.
 
That is funny. I have removed literally hundreds of wheel hubs/wedges in the last forty years. I have always hit the axle and I never had one that took me more than a few hours to get loose. I also never have damaged an axle bearing. One key is to hit it hard and sharp. Not just peck on it.

Pre-load it with an port-a-power or jack and the jar the heck out of it. If some one has broken the lip off the wedge then take a piece of pipe like others have suggested to push against the wedge. There is no way to hit the wedge hard enough to knock it loose. That is why you have to really hit the axle HARD!!! I have a thirty pound sledge that I use to do it with.
