Well live and learn, looks like I either cracked those back truck traction wheels or they are made that way or had been already broken. There is a fine crack from the outter wheel edge to the axle on each wheel. I got the truck covers off but thats what I found. The engine runs fine around the track and it doesn't seem like there will be a problem but I have not put on traction rings yet. At this point don't know what to think?

I've had seen tHese issues with the older MU2's. Best thing to do is apply super glue to the area then squeeze the wheel together and wait a minuteto let dry. Then install tires. I've done thIs number of times with good Luck. Don't let the glue drip down the axle as it may get in the bearing and Other areas.

There not lose at all. How hard is it to remove and replace those wheels?

Rio - more experienced members will respond I'm sure but I suppose the question is how big is the crack. IMHO, if it is merely a hairline crack and still tight on the wheel, I'd apply a bit of CA to it, let it dry, install the new traction tire and call it a day. If the crack is so serious that the wheel is loose on the axle it's a different story though. But, you are saying it runs fine around the track...so maybe not as bad as you think. I'd keep an eye out for replacement wheel/axle sets though for the future.

Im not going to make a problem where there isn't one they are very tight on the axle. But they are cracked. I may just leave it alone.

To reMove is too much trouble. I would still glue the crack to prevent further issues.

Ok... put a little dab of of Super Glue on the flat end of the match stick and spread the glue on the side walls of those wheels where crack was. Looks like it kind of melted the cracks together. Is that wheel plastic?

Hopefully putting on these traction rings doesn't put a lot of stress on the wheels.

Or if you have a lot of spare tyco geared wheels lying around like I do, just replace them I mean the entire axle with wheels.

The best thing is to use glue. I only rEplace if it's beyond repaIr. His wheels are just hair lined. Remember, tHese units are riveted together.

I'll know in a few days when I try to replace the traction rings. Hopefully, these wheels hold together and don't crack more and get worse. If so how hard is it to get in there and replace those axles?

How to drill out the rivets then replace them with a screw and nut. It's a fussy ordeal.

I just did this on a F9A unit, it does take some work, but this MU-2 runs better than ever, as I used the unsplit wheels off a 1980's plastic MU-2 to repair it, AND get wider traction rings than the old unit. Here's some pictures of the process below -
    
 
I used a drill bit to remove the rivet flanges. Then you need a pair of vice-grip pliers to wrestle the pins out of the motor body. After that it gets somewhat easier. I used the traction wheels off a later all-plastic MU-2, and had to use a dremel reamer bit, about 1/8 inch diameter, to ream out the later traction wheels, as the axle is slightly smaller than the older all metal MU-2. But it worked great, the wheels aren't split, and the traction tires are wider. I just finished the motor upgrade/reconditioning tonight on the guy's F9A unit, and it runs great! Anyway, I used a 4-40 tap to tap the whole length of the motor where the rivets went, and I happened to have the exact length black screws I needed to put in that only protrude about 1/4 inch, then installed 4-40 nuts and flat washer. No interference with the mounting bracket, the truck turns fine lock to lock. I was well pleased with the way this MU-2 upgrade went.  If you have the right tools you can do this, mostly a drill, 4-40 tap ( or use 2-56 screws ), I also had to tap the brass axle brackets and the main axle plate. I could have drilled them out the correct size, but I just tapped them as well, so there's good mechanical / electrical contact now. The tricky part was that I broke BOTH of the side frames off, so I drilled holes through them, and used #2-56 fine thread screws that I cut down with a Dremel cut-off wheel, then used a soldering iron to melt them into the side frames from the back. Then super-glued both plastic truck side frames to the main frame and the screws. It won't come off unless you THROW it at something!  Took me a few days to work out the kinks, but it was worth the work, and the guy should be happy to get his childhood engine back that is now working again. If you want to know anything else about my MU-2 experiences, just PM me.

| If it's just a hairline crack, super glue it. I've done it a few times. The pressure added by the traction tire will only squeeze the wheel together tighter...no harm there.

Ok... wheels are fine but I put traction rings on an one of them keeps popping off after the engine goes around track a few times. I'm able to put it back on with a tooth pick without taking truck cover off again but again it pops off. These traction rings are Tyco/Mantua made. The engine I'm working on is a RedBox NH mid, late 60's. Runs great but I gotta keep putting that ring on??

Well that's a new one to me - I've not had a lot of experience with traction tires but the way they fit down snug in the grooves it seems impossible they would pop off unless they were too big.
Any possibility they could be the wrong size?

New or used O-ring? I imagine once it stretches a bit, it may not stay on. Does it appear tight in the groove, trying to move it with the toothpick, or does it move easily?

I can move it with a tooth pick rather easiily. It fits but not real snug. I'm just wonder if a #5 O ring would work better?
As far as being new they said they where new. But, we know how that goes.

They should be tight on the wheel. I assume the one that's staying in place is snug. It may be old stock that swelled or deteriorated, or it might be just an inferior replacement.

Took traction rings off another old RedBox Engine and the traction rings appear to be smaller.
I'm wondering if a #5 size O ring if it will work better. May head down to Home Depot.

UPDATE.. I had the wrong PART #7907. THE TRACTION RINGS I USED ARE FOR STEAM ENGINES WITH THE FOLLOWING WHEEL ARRANGEMENTS 4-4-0 4-6-0 2-6-0 2-8-2 not a American made diesel.
MANTUA & TYCO DIESELS PART # 7740 are the traction rings I needed. YES, these is a learning curve!!
