Mounting Farmall MD wheel?

So on a Farmall MD do I need to mount the wheel center to the wheel before sliding it on the axle? Or is it possible to leave the wheel center on the axle and mount the wheel to the center with it on the tractor? Sorry for the stupid question but looking for advise.

Thank You

Either way is correct. Might be easier to mount the cast center on the axle first, then mount the rim and tire to the center. It will take some muscle. If you can get a helper or two, it will be easier.

If you can get help,(for safety)leave the rim mounted to the center, remove the "Wedge," and slide the center-rim-tire onto the axle. Then re-insert the wedge and tighten down where you want the wheel.
PS: I prefer the look of having the wheel center "Dished Out."

Thanks for the advise. I did not say it but the MD clamps on the tractor are different than my M. The clamps have to fit over the 4 little humps on the wheel. It seems like it would be very difficult to try and line them up while the center was on the tractor. I see a few guys using an engine hoist with a strap. I might try that.

I also agree with the dish facing out look. I do need to narrow both sides up a bit.

I used to do a lot of tire work on passenger cars and small trucks using a coats 4040 machine. Thinking about buying my own bars and mounting future tires myself. Any recommendations on the best place to buy the longer tire bars?

You can get tire irons, and supply's at Running's or other farm supply stores, just ask, chances are they got them!

Someone installed later wheels and rims on the tractor. Depends if fluid in the tires. If no fluid with cast wheel already on the axle. Block front of tractor and other wheel from rolling. With transmission in neutral turn wheel with two clamps mounted not all the way tight to top. Roll rim and tire around until two humps are near top or close then get it as close to wheel as possible and raise or lower tractor until you can lean the rim into clamps, then with two in the grove raise the tractor until bottom of rim can be pushed or pulled into line and install other clamps. When you get wheel humps near top to start rim on the wheel it can be turned to line the clamps with humps exactly before raising tractor into clamps. Transmission can be put in or out of gear as needed to move wheel. After getting the 8 clamps installed get them tight enough until rim stays on and then roll to tighten even if needed. If tires loaded it can still be done like this but you can't let the tire lean enough to overpower you. Helper works best or hoist with loaded ones. If you have 2 wheel clamps different from the other 6 instead of 8 alike a different procedure is used on installing the clamps and tightening.

Here where I raise 30" corn rows,I have to run 'dish in' in order to get the tractor narrow enough.

Easier to mount on the center if it is already on the axle. If off it is about 6 one half dozen the other. If changing tires it is easier to change on the tractor. Things hold still better and no bolting/aligning. For hauling purposes it is easier to haul with the dish in like for 30 inch rows or a 60 inch tire center setting. You can put 2 tractors together better on a trailer that way. As for the tipping argument unless you're working on mountain sides not an issue.

With two heavy clamps different from the other 6 for use on double mounting hump rims they are placed 90 degrees from each other and tightened, then wheel turned to place them at top. After mounting rim the other 6 clamps are installed and tightened. With regular MD wheels and dish out the narrowest setting is 72 inches from tire center to tire center. With wheels you have and IH double hump rims, wheels dished out the narrowest setting is 66 inches. wheels dished in is 52 for a MD wheel and 50 for a 8 spoke wheel. Close setting dish in really depends on rim and tire width and how far they will go in without contacting the tractor.
