Bachmann driver wheel diameter

[bigalspitzer]

Hi everyone, does anyone know what the wheel diameter is for the HO scale Bachmann 2-6-2 Prairie? I want to get some traction wheels for this locomotive and need the wheel diameter to order them. I have tried 4 times now to put bull frog snot on the drivers without any such luck unless someone else has a better idea. Thanks everyone.

Just measured it, seems to be roughly 9/16 of an inch. You should try looking it up or looking in the parts section; the diameter may be shown if they sell the wheels.

With .012 inches (roughly  ), representing one scale inch in HO, a measurement of "roughly" 9/16ths of an inch is almost useless.

Can't get any more accurate with the yardstick? lololol

Well, excluding the flanges, it was 9/16

You could get a pack of these and use the size that fits:

I don't think the traction tires go over the flanges. 😮😂😂😂

Every model railroader should have one of these in his tool box.
I had one in the 1970's and did some gear, motor upgrades with NWSL stuff using a dial caliper like this. Accurate enough. It cost me maybe six dollars at the time. Plastic and fiberglass construction. Never any error issues. Measure twice, cut once.
Today I have a battery operated, stainless steel one but still have the old one.

Or you can use small rubber bands.  Basically the same thing.

That's why I said "excluding the flanges."

Right. New glasses needed
