1750 6 row Conservation Planter

Help, Need to replace bushing JD part A64190. I know I have to pull the front shaft as I need to replace bearings A22097 and the shaft as well.

Is there any trick to the trade that will allow me to do this without basically pulling the shafton the other side of the frame and pulling entire wheel assembly. Bushing A46909 is welded and looks like all I need to do is drive A64190 around it. A64190 has worn from numerous up and downs and A64909 is wearing in to the frame.

What seemed like a easy fix now looks anything but and this isn't the year to pull it up to the dealer and leave to pick up before next spring. If corn was 6-7 dollar it might be.

Thanks,

Randy

Need to do this for all 4 wheel assemblies that drive the planter.

On a 7200 I took a handyman jack and jacked up one side and then the other. I loosened the u bolts that held wheels up so they had some play in them. 2 people make it a lot easier. don't know if a 1750 is the same.

Might seem too basic but how did you get the rest of the old bushing out

The bushing you think is welded if it is like mine really isn't. Just beat it out with a hammer.  Just find a socket the right size and start taking your frustrations out on it. I hope I'm not making it sound easy because it isn't.  My arm hurt for a week after I put mine in.Smiley Very Happy

If that is the case, spend the money on a GOOD air hammer and hammer/punch set for it.   I can't begin to tell you how many instances of 'hammer arm' that has saved me.  
Also, if you can cut a slot in the bushing with a torch, it makes removal much, much easier.   It is kind of an art form, to cut the bushing, but it can be done.   If you were in WC Nebraska, I'd offer to do it for you, for supper, but I don't travel very well, LOL. 

Or, you can practice a little by bolting/welding two pieces of metal together, and figuring out how to cut through just one piece without harming the other.

That was one great thing I learned in welding school, how to cut a nut off of a bolt, wire brush the bolt threads, and re-use it,  how to cut a bearing off a shaft without hurting the shaft, and also get the outer race out of the pillow block, and re-use the pillow block.  Takes a steady hand, good eyes, and more than just a little practice.
