Well I have done a few of those from the tractor I am working on and a coupule of parts tractors. I had to use the sledge hammer the wheel out of the rim method, then I ended up taking the snap ring off of the cam, other end from the 3/4 hex, and pounding the cam back and forth with a big hammer, setting it up on partly open vice jaws, until a socket and 4' pipe would move them. I broke a few sockets before I got to this method. They can be a tough one. I did one or two an evening rather than face all of that at once.

Never seen one get THAT stuck....!! 'Course mine get moved every year... Soak them good with oil, Jack the wheel up, and loosten them with 3 or 4 ft pipe on the ratchet.. If ya don't jack it up, loosten the top one first.. Tighten the bottom one first, if you don't jack it up. Tighten them as far as they will go, and you must use the slide stops, or the wheels will slip.

I would just take the two bolts out of each block. Be carefull not to loose the little block that is in the cam. That is what locks them to the wheel. Don't take the whole wheel off because you have to take the eight bolts out of the axel and it is easy to twist them off. You will have as much fun as getting the blocks loose on the wheel. Put them in a good vise and heat with a torch. If you have craftsman tools, put a 3/4 half inch drive socket with a breaker bar and a 4 ft pipe and they will come loose. I have done 26 of these this way and hasn't failed yet. When you get them loose so you can spin them with your fingers, give them a good coat of JB-80 or anti-seize. this should solve your problem.

If all else fails do this - its what I had to do. Nothing would move the cams after days of soaking, hammering, impacting, cheater pipes and etc. Remove the wheel and tire assembly from the axel hub. Remove the two bolts that hold each cam assembly to the wheel. Lay wheel assembly rim and tire on the ground with the outside facing up as it was mounted on the tractor. Then use the heaviest sledge hammer you have - preferbly a 16 pounder and drive the wheel down releasing it from the cam assemblies. After it clears one of the cam assemblies it will drop out onto the ground. Now you can remove the cam assemblies from the spiral cam guides. Now you can really work on the pins, lugs by putting them in a good vise. Using a torch, penetrating oil,wire brush and a hammer you can begin to loosen cams and finally get the pins loose and be able to rotate them. Its a pretty good job. Hope it helps.

A 3/4 DRIVE IMPACT WITH A6 SIDED SOCKET WORKS
GOOD.

I had the pleasure of this experience last weekend. Turned out not to be too bad. Heat with a torch, gentle rapping with a small hammer directly on the 3/4 hex to break the rust, turn back and forth with crescent wrench. Use neversieze before reassembly. Be very patient. I don't know, but I would imagine these to be pricey.

If you have access to a torch, you can heat them up with that and then work them loose with an impact wrench. If not then you might end up doing what I had to. Take out all eight bolts that attach the cam assemplies to the hubs. then with a sledge or a small car jack, slowly and carefully work the rim out off of the hubs. Once I had them off, it took heating them in a small forge until slighlty red hot, and the impact wrenth to get them loose. This is after I'd allready shattered a socket using a cheater bar on the breaker bar. Clean 'em up with a wire brush and grease heavilly before reassembly.
