How do I move the rear wheels in or out on a 1956 John Deere 70. And How tough is it on one that has never been moved. Thanks;Ken

Very tough!

Do you have the Owner's Manual? I assume you have the F1500R rear wheel casting. Positioned around the Hub are five bolts. The center one, and the two outside ones, plus those on the inside of the hub, are the "locking clamp" bolts.
You loosen them up (you could even remove them entirely). The two remaining bolts, located between the clamping bolts are what are called "jacking bolts". Theoretically, you turn them INWARD, causing the "sleeves" on the axle to become unseated or loose. "Theoretically" all you have to do is turn the adjusting bolt (it turns a pinion gear inside the casting which moves the wheel in or out, using the "rack" which was cut into the axle).

All this is theoretical. What actually happens is that the wheel casting rusts solid on the sleeves and no amount of beating (or so it seems) will move them. Do a search, here on this site, on this subject. There is quite a lot written about it in the YT archives. It usually takes a LOT of JB80 and much patience.

Once you get them loose, I suggest moving them at least ANNUALLY, thereafter to keep them that way. Good luck.
