Rear rim moving on cast hub - Case 2090

Anonymous-0 · Apr 24, 2013

The right rear rim is moving about 1/2 - 3/4 inch on the cast hub. The tractor is a Case 2090. The lugs that connect the hub to the rim look a little worn as do the "bumps" on the rim. How common is this?? I think I have tightened it up a time or two and wonder if it will even tighten up anymore. I do have 4 other new "bumps" on the rim I could use as well as moving 4 presently non-used driving lugs (less wear) to that location. Will that tighten things up??? I am afraid that the ends of the cast lugs might be worn and it may never tighten up properly. Any ideas will be appreciated. Thank you.

You should have a lug on the rim that fits into a notch on the cast center.

You can reposition the rim/wheel to the new 'bumps'.If the cast lugs are worn,they will need to be replaced or the same problem will start all over again...Dont ask how I know this.

There are four lugs that are drivers - they fit onto four individual bumps or rises on the raised circle around the rim. Of course there are several more lugs around the wheel. There are four more raised bumps that have never been used on that same raised circle around the rim - I could move the driving lugs to these four. What I am saying is that there is play between the four lugs that drive and the four raised bumps on the rim that are driven. Actually more than just play, I think it might move an inch back and forth. Power shift probably doesn't help.

If it has been run loose too long, you need to have some experienced eyes look it over so a worn rim does not crack and come apart and hurt somebody.

As far as tightening it, block the other tire, jack the tractor up enough on the loose side to take most of the tractor's weight off of the rim and tire and use a 3/4 inch breaker bar with a cheater bar and work your way around the wedge bolts a couple of times. Do it again after driving it for a while.

I think that the lugs are pretty much drawn up tight on the cast hub. That means they are pretty much pushing outward as much as possible unless I am missing something. I can see that some of the casting where the rim bump goes in is worn. I subpose they aren't the full length.

You need to do exactly as DeltaRed stated. The powershift or brand has nothing to do with it. The ops manual with have a tightening sequence and try to tighten the wedges evenly.

I move the lugs to the front of the slot so that they do not have slop.
