Wheel sparks-What to do?

[nachoman]

Athearn, NWSL, and JayBee and maybe others all make replacement wheels. I think the Proto2000 wheels also fit. It's simply a matter of pulling the cover off the bottom of the truck, removing the wheelsets, pulling the wheels from the gear, putting the bearings on the new wheels and pressing back into the gear, and re-assembly. Once you get the hang of it, it only takes a few minutes. I can't remember if you have to remove the sideframes, though.
