Changing Rear Wheel Spacing

Anthony · Aug 13, 2016

I am wanting to change the rear thread spacing on a tractor with the multi-postion wheels. I need to both reverse the center disk on the hub and also change the positioning of the rims on the center disk.

Is it better to take the whole wheel assembly off and work on it on the ground and then reinstall? Or is I better to remove the rim from the disk while still on the tractor, reverse the disk, and then bolt the rim back onto the disk on the tractor? The tires are 14.9 X 28, the tires are not loaded. The wheels are held to the hub with bolts, not studs with lug nuts.

I'd rather take the whole wheel assembly off and lay it on the ground,now I have another tractor with a loader to make the job easier

I would do it right on the tractor. Remove the rim/tire.Then reposition the wheel/disk. Reassemble on tractor. Use plenty of blocks/jack stands......Those things get heavy and can get away from you.Be Safe!!

I would think it would be easier to manhandle the wheel and center as an assembly to get the center turned around and bolted on, then unbolt the rim and position it to where you want it to be.
Don't forget to flip it around if you want your valve stem on the outside.

You will have to pitch the tire up once laid on the ground ,not that you aren't able , but I'm not so I would either get some help , a young man strong back weak mind, or a loader tractor to do the lifting for me, and to more correctly answer you it will be easier to install the center on hub first then wheel on center second if you don't have a stud or something to use as an alignment pin .

"Don't forget to flip it around if you want your valve stem on the outside."

Depends on whether you're using it around livestock or not. It's not a good idea to have them on the outside where cattle can rub on them and shear them off.

Where is the center disk going to be on the rim. If center disk is to the outside of the rim, you have to re-assemble as a unit back on to the hub.

Since the tires are not loaded, roll the tire away and lean it against something secure to do the re-arranging. DON't lay it down and have to pick it back up!

lso, sometes you have no choice if you need an exact spacing for row-crop, etc.

ood point; the center disk will have to be on the outside. Maybe the disk is scalloped so that I can rotate it and pass the rim to the inside, have to check. Thanks.

Well if your going to be flipping the center then jack it up so both tires are off the ground and take the centers and rim off and put the left one on the right side and the right one on the left. That way the tires will be on correctly and the centers will be flipped then adjust the rest as needed. That could well be easier then trying to take the rim off the center and then flipping he center and putting the rim back on the center

Actually, there is no guarantee that the tires will be pointed correct. If you reverse the direction the wheel is bolted to the center disk then the wheel will stay on the same side after you also reverse the disk. In a way I think it's good that I don't have to switch anything from left to right; that way I can just work on one side at a time, the tractor will be on solid ground, and I can use the jack to make minor adjustments.

These are regular 8-position loop rims found on many tractors. Right now, since everything has to be unbolted I am leaning toward removing the rim from the center while it's still on the tractor, but I'm not really sure. I've only changed rear tires on tractors that have studs and lug nuts and I'm not crazy about the idea of working with a wheel that uses bolts to the hub. But it is what it is. Here is a picture of current setup.

I would remove rim, then the center. That will reduce the weight of having to handle both at same time when taking them off. Turn center around and bolt to tractor. Rim and tire will have to be mounted on opposite side of tractor and exchanged with other rim and tire to keep the tread direction right, IF turning them around. I am assuming you want the rim bolted to the same side of center (inside/outside) as it is now, when done.

Break loose all the bolts before you remove it from the tractor. It will be easier when the wheel and rim are firmly held by the tractor.

o, I have to move it to the other side of the center. I think everything can stay on the same side of the tractor.

If you just need to move it from the outside of the plate, to the inside you should be able to just pull the bolts on the rim. Then turn plate and rebolt the rim to the plate.

Here is the chart from the JD operator's manual. I have to change from current position[b:14c8f85254][color=red:14c8f85254] "D"[/color:14c8f85254][/b:14c8f85254] to new position [b:14c8f85254][color=green:14c8f85254]"G"[/color:14c8f85254][/b:14c8f85254]. Am I correct that all the pieces can stay on the same side of the tractor and I only have to work with one side at a time?
