I was changing the traction tires on a 1960's Tyco engine today when I noticed that both of the plastic drive wheels had a crack in them. The crack on each wheel ran from the outside all the way in to the axle. I also noticed this on one of my 1960's streamliners. Has anyone else seen this before, and is it something I should be worried about?
Kinda hard to see in the pic, but the cracks are at 3 o'clock on the left wheel and 6 o'clock on the right.

hi cheez like all things plastic has a life span dependant on heat,water etc plastic becomes very brittle with age,and in average enviroment not much to do other than replace,even if you replace with metal insulated ones the plastic insulater will deteriate,but will take a little longer to do so,and that is what i would do ken

| If I have a cracked wheel that's not noticeably out of round, I just glue the crack with super glue, which seems to help prevent further problems.

Hey Ken. You're right about that, and since they're 45 year old drive wheels I'm not surprised they cracked. Unfortunately I don't have any replacements for the 1960's grooved wheels. I'll try Adams super glue method. The wheels are still perfectly round, so it should work fine. Thanx for the help guys.

I have glued them together also.
Another alternative is to use the ungeared wheel with traction tire from the tender drive Power Torque drive.

Hey Ray. I hadn't thought about the wheels on Tyco steamers. Are they the same size?
Anyway I put some super glue on the wheels and replaced the tires, so it should good for a while.

Hello Cheez, I found the same cracks on one of my engine wheel sets also.
Thanks for the cure for the problem from the others.

They are the same diameter with the PT traction tires installed. They look a little different but hard to see when the side frames are installed.
I replace the ungeared wheels with traction tires on the steamer tenders with metal wheels to improve the electrical pick up and use the ungeared wheels with traction tires on the MU-2 power trucks.
Adding a little weight to the tender makes up for the 2 traction tired being removed and the tender is more stable on the track.

Ray, I've done the same thing to improve the pickup on the Chattanooga tender. I've also added NWSL 1/8" washers to the driven axles between the ungeared wheel and the truck block on a few of them, since the gearing tends to come out of mesh without them. I don't think they gauged the driven axles correctly - they're always too narrow, and need to be re-gauged.
I do have one PT geared wheel with a split in it as well, which gives it a click once per revolution.
