We got the plows hooked up and was ready to start plowing when we noticed that the right wheel ( furrow wheel on the tractor) Was out to far. we was told by a mechanic and my shop manual to unscrew the 3 cap bolts on the out side of the wheel approximately 5/16-inch. then turn the jack screws clock wise untile outer grrove in each screw flush with outer hub. turn pinion shaft screw and remove wheel. Done that but it still wont budge either way.The bolt is stuck bad I tried jumping on the breaker bar a pipe for levrage even Pb blaster nothing would break it loose I did break the breaker bar though, But is there any why to get the wheel in with out having to heat the casting and breaking the bolt i'm afraid of breaking it off, and will it throw its center of balance off enough to be concerned if we don't adjust the other wheel in also ?. We are using a 3 12 bottom plow John Deere plow from point of the plow to the out side of the tire is 39 inches so it needs to go in it is not following the rear wheel. 2. And my Hyd, pump is whinning a lot it never done it before but does now, the tractor has set all winter and most of summer last year and not been moved just started and warmed up. The oil looks a little foamie I use anti wear Hyd oil formulated for older tractors, and the it's lifting time is delayed which I'm hoping once I get to using it that it will fix it self getting the seals and stuff wet again. nothing like setting around even now the tractors go bad lol. Thanks for the Help in advance

Gene.. I had the same thing on my 730 2 weeks ago. I loosen the 3 bolts about a half inch and then drove the tractor around in the yard applying the brake forward and backward and turning also, after about 5 min it broke free. My bolt that run the wheel in or out on the alxe was stuck, so I jacked up the tractor loosen the 3 bolts and drove the wedge out enought to move the wheel...NOW... make sure that the 3 bolts are caught by a couple of thread so that the wedge will stay alined to go back in. Good Luck. My 2 pennies

Where is the rim positioned on the center casting? If it is positioned in the outer position you can re-position the rim by loosening/removing the 8 clamp bolts and using the outermost rail on the rim. If the rim clamps are on the outside of the center casting, they can be moved to the inside as well. If you're lucky this will put the wheel in the ballpark of where it needs to be, although you might still want to spend the time to fix the real problem of the rusty pinion/wedge. Good luck, Mike

This is one of the most discussed topics on this site. Search the archives using wedge removal as a search word and you will get a lot of tips.

One that seems to work best is to get a piece of pipe that has a slightly larger dia than the axle and a little longer than the exposed axle. Grind one end 180 deg about 1/4 inch shorter, butt the longer portion against the wedge to be moved and use a sledge to drive it loose. It would help to have a piece of steel welded on the other end to hit against.

Good luck, they will come loose but it takes a lot of the Right force.

I have moved them by taking the inside 3 bolts out as well as the outside 3. The next trick is to loosen the wedges. If the wedges move, you can move the wedges and then move the hub. It is alot of bull work but can be done. The best method is to remove the center hub & heat it with the torch and put never seize on it when reassembling it.
