I jusy cant figure what happened here. I went at it again after I got home with the same setup, puller and bearing seperator and it still wouldnt budge. I read all the post's that everyone left, I especially liked the one about gauling the shaft up when it went on but I knew that wasn't the case since it slide on without any problem. I grabbed the porta band and was about ready to start in on it when I thought maybe it just needs a little stress relief. So I got a drill and a 1/4" bit and drilled down to the crank, filled it with pb blaster, put the puling setup back on it and started cranking till it wouldn't crank anymore. Then I gave it a good hard smack with the sledge and it poped and moved. I will say that I had to smack and crank it all the way off. Took about a half hour of cranking and swinging to get it all the way off. I dont know what you guys think but Im gonna hone that thing out to a tight slide fit and drill another hole and thread both up for set screws. Im not going through that ever again. Any comments on my idea there???

scott, Glad to hear you got it off! You cant hone the bore on the pulley because you have the keyway to contend with. Your best bet would be to hold the pulley in a lathe and get a flapper wheel with a drill and buff until you get the right size in the bore. I made mine .0005 smaller than the crank diameter. I have seen as much as .002 interference fit on that pulley. They can be a bear!

Scott, what the heck did you pull the pulley off of that took all this effort.

It was a Super A. No slight intended against your jack puller there but if it isn't 1/2' steel and solid box with hardened struts, it wouldn't have helped on this one. And even if it is that good, I dont think a 5 ton jack would have broken it free. I've pulled a ton of pullys, hubs, gears, bushings, sheaves, you name it, even very big stuff on old beaten, rusted earth moving equipment and this one just flat out had a curse on it. I have never been "nearly beaten" this bad.

Scott, I think you have under estimated my puller.

Plate is 3/4 inch plate, rods are 3/4 all thread, Same that I used on my 35 ton hydraulic press(which I built 25 years ago and haven't run into anything yet that I haven't been able to press.)Cross piece is made from 2x2 by 0.025 wall thickness (was going to use solid shaft but figured that was an over kill). I used a 10 ton porta power, I think my 5 ton would have worked fine.

Pulley came off so easy from the boy's SC using my puller, would have believed that there could be all the horror stories. But job is made easy with the right equipment.

I read all the horror stories in the archives on removing Farmall A,B,C AND Cub pulleys. Figured I wasn't going there. That is why my puller is an over kill. I can guarantee it would have removed you pulley with little or minor effort.

Probably would have, that things a brute. No such thing as overkill in pullers in my opinion.

Scott needed that puller like the one you made using a ram or bottle jack. Hal
