I need help! I bought a JD 4020 and am trying to move the right rear wheel out on the axle and it is frozen. I have done everything i know to do to get it to move with no luck. Any suggestions?

A good soaking with a premium penetrating oil for a couple of days would help too.

Additionally, you need to be sure that you understand what all the bolts are for.

It has been awhile since I moved mine, so I pretty much forgot and folks here can steer me straight.

You need to loosen the wedges, then put pressure against them to back them out, then the sideways one cranks the wheel up and down the axle; it doesn't just slide.

And I like the idea of hitting the wedges with a pipe and sledge, rather than do as mother deere recommends and that is to smack the end of the axle. Gives you the heebejeebies to to that to a piece of machinery....but I have done it and made it through....luckily.

if you have a big cherry picker or tire stand just support the tire and take the wedges completely out and take it off that way. you can take the inside wedge bolts loose and use a large punch and hammer to hit it out. if you dont have somthing to lift the tire you can take a big sledge hammer and hit the end of the axle as hard as you can while the jack bolts are tight. its not going to hurt anything internal. the only thing it might hurt is the outer bearing but most are worn out anyway.

I made a tool to get them loose.
Took a pipe that would fit around axle, that would hit the wedges. Cut half of the pipe down 1/8 inch so that it would touch just the wedge.
Then welded a plate to other end and with the screws loose would hit with mall. They will come loose. Have done all our tractors, and they were TIGHT.
I would NOT hit axle shaft, could cause some major damage.

It took me 10 minute to get them loose using this tool (No lie)
Took 1/2 tank of oxygen and actelene and 4 hours to get other side loose before i made the tool.

I"m another who posted the same idea several times over the last few years- it works great. No sense in beating on the axle- you"re not trying to move that. Just end up with a mushroomed axle, maybe internal damage. Pipe over axle idea works fine if working alone- just park the tractor so the wedge you want to move is on top, pipe lays against it, or you can weld a nut on the pipe and secure it to the wheel with a tarp strap. No helper needed to hold it.

When I worked in the dealership we would loosen the 3 wedge bolts, tighten the jack screws, and beat the end of the axle with a sledge hammer. After a few swift hits, tighten the jack screws a little more. They will come loose. DO NOT beat on the jack screws themselves, you will break the lip off the back of the wedge.

They should just post a link on the site somewhere that would have all the best tips from the archives listed. This could be ,in my estimation, one of the most asked question on this forum along with mag questions .It pops up every couple weeks along with alot of Mag questions .
