Sorry if this has been covered before. Have been reading the board for about 2+ months now.
- Have 1955 JD 50 that I would like to adjust the rear wheel spacing. Got bolts loose on left side, inside and out, but can not turn the "pinion gear" and the wheel collars appears rusted tight to the axle shaft also. Right side can not even loosen the bolts inside or out. Had a 8 foot pipe on the end of a 3/4" breaker bar and bent the bar. There is paint on the bolts and will work on getting it off to get penetrating oil into the bolts. - Called local dealer ( hour and half away ) and he suggested heat the wheel casting "very hot" not just warm with a torch and then pour a bucket of water on it. I thought this would break the casting for sure. He said it would break the rust up and works 80 percent of the time freeing up the wheel. - Thanks all in advance for your comments.....

OK here is what we have..... . Sunday....

- Did lots of soaking and got the left side loose. The wheel dish moved out about 1/4". But, both collars have not moved. I oiled up the jackscrews, put a spot of grease on the end and tightened them up. The wheel pan moved out, but the collars stayed at the same place on the axle. The pinion nut is still frozen in the wheel dish. Am I stripping the gear?????
-Not sure what to do from here. Should I try to press the collar opposite the pinion gear inboard??
-Also the bolts on the right side still frozen. Still scraping paint and soaking. - Thanks in advance....

This is the same as on my 70. DON"T put too much pressure on the jack bolt. They push against a cast iron collar, and you'll be $orry if you break it. Put a lot of rust cutter on it (I've found PB Blaster works pretty good) and then after a while, take a BIG sledge hammer and hit the end of the axle squarely. The vibration in the axle will break the rusty wedges loose. In trying to get the wedges loose, I had been pounding on a wrench on the jack bolts with a 4 # hammer. After I hit the end of the axle, the wrench practically turned by itself.

Good luck getting the pinion shaft out! I had to put a HARD shaft in the hole opposite the head, had a buddy heat the area with a rosebud on the acetylene torch while I pounded with the 16 #er. After a half hour, the pinion gear started sliding on the pinion shaft and the shaft came out. $70-$75 later at Ma Deere, the pinion shaft and pinion gear roll the wheel in and out like a champ

Gerry:

What I did on my 70D, was to loosen the three clamping bolts about a turn or two. Then I tightened the two jack bolts as tight as they would go. Oiled everything. Then put my impact wrench alternately on the jack bolts while tapping on the through bolts with a three pound hammer. After about three minutes of letting the air wrench hammer on the jack bolts, the wedge moved inward against the through bolts. Then I removed the through bolts and pushed the wedge free. Then rotated the wheel and axle so the rack was down, and the wheel dropped free. Slid it off the axle, and freed up the rack bolt like Tye said. The other side came off exactly the same way. I did buy a tap to clean all the threads concerned, and lubed the threads on assembly.

Hope you have my good luck.

Hey man I remember I had the same problem on my 53 jd 50. What I did to free up the pinion gear was I took off the entire wheel dish. The dish is held on with two pieces of metal that form two wedges. Pound out the bottom wedge (oposite side of the pinion gear) By doing this you free up the dish enough to slide it out and you don't have to use the frozen gear. I slid it off with the aid of a loader. After you get it off. Lay it on the ground and soak the sh** out of the gear with wd -40, oil, or what ever you use. Then put your pipe back on and turn the gear. Make sure you have a Craftsman 3/4 drive socket wrench to turn everything. I broke a lot of wrenches freeing my wheels up. Hey if you have any questions email me or post back up here. Good luck. Peace.
