863 rims

[Flip57]

I recently had one of my rims crack like a spider web around the hub of my 863. So I ordered a new one and asked that it be the stock rim as I am pretty confident that the rims are original and hold the tires close to the body of the machine. The new rim sticks out 6 inches further than the others. I had to use it or not use my machine. I need to order another one that will match the other three but not sure how to describe to the parts guy. Anyone else have this issue?

your machine must have inverted rims. however sometimes rims can be put on both ways, try it with the valve stem on the inside.

Take your wheel off, lay it valve stem up and measure the inset to where the hub of the machine mates to the rim. Give this to the bobcat dealer and they should be able to match it. Some machines had inset rims to make them a little more narrow. I have one of the older inset rims. Is your rim a smooth solid piece of steel in the center or is it a stamped center?

I had three of the rims that were stamped and one was solid. the solid one is the one that cracked. They all were the same inset though. I guess that is why I assumed it was the stock inset as they match the specs from the manual.

All the solid ones I've ever seen were the inset wheel that makes the machine narrower. I could be wrong but that has been my experience.

I think I have a solid rim in my loft and a standard inset wheel without tires on them. I'll go out and measure them and report back if there is any difference. I will need to verify that the stock inset is a Bobcat rim and not one that has been painted orange.

Just checked and my rims seem to have about a 7" offset. I checked the rim on my S300 and it has about a 7.25" offset.

Thanks, Bobcatguy. I'm away from my machine working out of town for the next three weeks but I will get back to you.
Besides looking goofy, is there any issues with having one wheel stick out 6" further than the other three?

you can't do it, when you turn technically one width is wider than the other causing a different turning radius, the wheels will fight eachother

try flipping the rim. If the valve stem is out face it in toward the machine. This should narrow you up. I've had machines that had the wrong rim on and ran them. They worked okay but I'm not talking 6" they were more along the lines of 1 to 1.5".

Tom,
As they are "skid" steers, technically there is no turning radius, is there? The tires were all 4 bought at the same time so the diameter (wear) should be identical and that would be the only thing I can see that would put the hardware in a bind. Unless I'm missing something.

yes but technically when you turn the wheels arent turning at the same speed, i don't know the proper terminology but it will bounce a bit

I could be wrong but I do know that technically, the left and the right side act independantly. They each have their own drive motor and only the front and back wheels are connected via the chain case. I don't want to hurt my machine but I don't really see where this will cause any problems besides looking a little goofy. As soon as I can get a tape measure on the machine I will order another rim and save this one for a spare. I have an old tire to throw on it.
