The stuck or seized roller will have a worn or flat spot spot in the surface area aganst track .If the bearings are gone then it will be lose on the shaft or they will rattle and or ring like bells if lose . So if you are hearing bells it may just be rollers .It is always a good thing to watch the bottom rollers when someone else is running the machine of course this isn't always easy to do if you don't have others who will run the machine .The minute that someone else offers make it one of the main objectives to watch .Just keep a watchful eye on any resistance in top roller movement if you have snow holes in the tracks you can see top roller when operating machine.Keep dirt and frozen debris from around top and bottom rollers when parking over night in cold tempritures .Securely park the crawler on two wood blocks under drive sprocket and front idler and check the bearing play on the bottom rollers by lifting up on roller slightly .Be careful doing this .Digitup.

Usually if the sprocket is hitting the roller, the bearings are out of the final drive.

A question- I noticed on my 2010 crawler when I had my right track off that there is a little bit of lateral play in the sprocket. It is almost imperceptable but is there.

I am assuming that there shouldn't be any play at all? Is that something that could go bad quickly on me or is it something that will wear slowly over time? I need to keep working on it but am trying to get a feel if I can complete my project before I get in the final drives.

Most likely need to shim the bearings to the correct preload. Keep in mine, they may have a greater tendancy to spin on the axle if not properly preloaded.

Thanks Lavoy- I am assuming that I would have to remove the final drives to do this, correct? Also when you say "spinning" on the axle do you mean that it could "slip" like a worn clutch and quit turning at some point?

thank you

tigerhaze,
No, I think Lavoy means that the inner race of the bearing will spin on the shaft galling the shaft and then you have two parts to replace or repair.
If the 2010 final is anything like a 440 final you can access the shims on the backside of the final without pulling the final, on the 440 there is a cover that is the point for this adjustment. You would have to drop the final pan to be able to rock the bull gear back and forth to set the preload.
May be an entirely different beast though, for all I know, which sometimes isn't much
