So, the new-to-me 4-4-2 #8602 has just shed a traction tyre. I’ve tried to replace it, and it is obviously split, so won’t go back on. The engine now slips like crazy.

This being the U.K., where there are no Lionel dealers and shipping on small parts from US is “silly money”, I’m open to suggestions on this. Is there any common solution involving gasket goo or adhesive? A rubber band the right size? 

The alternative, given that I didn’t pay a lot for it, is to toss it in the parts tray. I could muster the whistle tender with the Scout, for one thing. The rods would dress the Scout up a little, if they fit? They look the right size, but I’m not sure about the fixing into the wheels. The front bogie would look good on the Scout, too. 

Original Post

I just put new traction tires on. 

I have to say, I'm unimpressed with Bullfrog Snot, not only is is messy, it doesn't fill the groove in the tire, so you'll end up with oddball running issues.  Also, Bullfrog Snot seems to dry up in the jar after one use when it's opened.  Yes, I had the top on tight.

I’ve never used Bullfrog Snot but I have used similar compounds at work, they’re not my favourite substance. 

I’ve put out an enquiry for a new traction tyre in U.K. Failing all else, I’ll be in Florida in Jan/Feb and I’ll bring a shopping list of small items..

Useful information about the traction tyre part number. I’ll put some on my list next time I order something. 

Meanwhile, I found a bag of assorted rubber bands in the bureau at home. Sorting through them, I found about half a dozen which were flat section and the right sort of size. I’ve fitted one to the loco, it has run around my O27 test loop for about 10 minutes, hauling those heavy 24xx coaches and seems fine. If it only has a short life, I have five more in hand...

 

I found a YouTube suggesting using o-rings as traction tyres. The poster seemed happy enough... my guess would be that it worked well enough for his application, because diesel wheels are quite small diameter, but finding one in steam engine sizes (around 29mm) would be more challenging. 

A quick google indicates that an o-ring that size would be at least 1.6mm thick, which would be proud of the groove? 

 

I have a better idea... get another 2034-100 motor and bolt that into the 8602 body.  No more rubber tires EVER!!  Also, ozone and more coasting distance.  Most MPC-era 4-wheel motors will also work.  But you would have to change or remove the E-unit, because there's no slot on top of the boiler for the protruding lever.

Isn't it amazing that a 67-year old part will bolt right into a modern train!?

Creep, coast, and pull.  We're not talking about cold fusion here.

A quick search indicates that “square section O rings” will need work to get the exact search words....

I did look at using the Scout 2304 motor, or stripping the #8602 because I could use various components, and it wasn’t expensive. However that brought about another issue... the wheels on the Scout aren’t quartered accurately, so the side rods won’t fit as it stands. How are they fitted? Pressed on? 

The wheels are pressed on.  I'm NOT a fan of those aluminum wheels with the plastic centers that Lionel began using circa 1982.  If you install a 2034-100 or MPC-era 8209 / 8300 / 8302 motor, you'll probably have to use the side rods, crosshead guides and crossheads that came with it.  I know this means omitting the side rod, but I just like the way these run with AC motors so much better.  And as you've learned, tires are an accursed nuisance!!

Unless you have special tools and a lot of experience, trying to pull the wheels and re-quarter them isn't a good idea.  It'll be tough to get them back on tight, square, and without a wobble.  Also, the bosses for the side rods are very different from the newer aluminum wheels, and the "front" pair on the 2034 might not even be tapped for the hex screws.  I wish there were an easier way, but for me these little 2-4-2s have always been a "one-armed Billy"!

Creep, coast, and pull.  We're not talking about cold fusion here.

That’s all pretty much what I’d concluded from inspection of the Scout and it’s 2034 motor. I’ve never had much luck pressing wheels on and off, and I’m sure I’d end up taking both wheels off of one axle, to get the rods and gear wheel synchronised. 

I’ve now got a more-or-less solution to the traction tyres for now. I’m going to the local model shop on Tues to see what they’ve got in stock, and I can order some Lionel ones while I’m in the US in Jan.

Absolutely. Can't abide it.

And, per Mr GRJ, there are issues with the product anyway.
