Insulator on correct side, no cracks. Locomotive running fine.
Guess we'll never know what ent wrong.
Thank you for the replies and suggestions. This forum is always helpful.

gdelmoroWouldn't the insulator on the wrong side constantly short the district?
Ill check both for crack and insulator. Wouldn't the insulator on the wrong side constantly short the district?
Double check to ensure the plastic insulator, barely visible where one wheel's hub meets the axle, is on the 'correct' side of the truck.
Probably best before you put it on powered rails.
rrinker Is there excessive side play that allows it to move to one side far enough for the opposite side to drop out of the bearing? Or maybe it was already half out due to either not being installed correctly or being tossed in shipping? --Randy

I checked for side to side movement and it moves about the same as the other 11 tender wheels. I also used digital calipers to check the space between truck ends. The spacing was exactly the same on each wheel set / frame from side to side and font to back.
I First found the wheelset on the tracks when the mainline shorted. When I lifted the locomotive off the track (that cleared the short) I noticed the wheelset was still on the tracks.
Hopefully it was just an anomoly.
I've run it arround the layout both forward and backward, seems to be good.
Don't know what I else to do at this point. Guess we'll wait and see if it happens again.
tanks for the replies.
Assuming you have a good inside caliper, or a good eye, carefully measure the distance between the inside faces of the truck frames at one end of the truck, then at the other. Obviously they should be the same. If they are not, see if you can tell why not.
Perhaps the easiest 'retention' fix is, with the wheelset in the truck, to put a tiny dab of nail polish or similar material (the 'glyptal' used to retain adjustable pots or other settings in radios comes to mind) in one or both of the little notches that optimize inserting the cone-ended wheelsets -- it was through these that the wheelset probably came out, and 'closing' them with the wheelset in place will prevent that without in any way compromising either running or transporting the locomotive subsequently.
The reason to use nail-polish-like material is that, if you ever actually DO need to remove the wheelset -- or return the locomotive for service for some other reason -- , it will pop off with gentle pressure.
Once the wheels are in place, they should not fall out by gravity. If they do, I would check if the trucks are not warped. A blow might have bent them at some point. If they are bent, you might be able to gently bend them back to their original form.

Did it fall out while running?
Tell us the whole story.

I put the wheelset back in aNd it seems to be working. However, I'd really like to know why it came out. Here are pictures of the Truck straight on and fro each side.
I'll take a couple photos. It's a wheelset.
Good quality photo, pls.
Is it a wheel, two wheels and the axle, or the truck that fell off?
Hi all, anyone have this problem? Is this something I can fix without sending the locomotive back?
