IF the centers are like the 4 4 0 & mogul they just 'flick' out,
Try using the back of a knife (so it is the wide and not the sharp side) and see if the can be lifted by pushing it in between the center and the rest of the wheel; it hides the fixing screw.
Part of my problem is that I don't see any good place to put the blade. I'm not sure how the 4-4-0 and mogul drivers are made, but on thise model, the piece I want to remove is the entire driver center, spokes and all. It seems to be the same construction as the Big Hauler and Annie drivers.
I would not remove the wheels though, they may be difficult to get back: fiddle a piece of paper up the back to stop red paint getting onto the chassis and have another go.
I can remove the wheels without difficulty, though they come out as a unit with both wheels and the axle (and the motor & gearing on the rear set). I don't really need to pull the wheels off the axles, just remove the centers for painting.
The cylinders (again from the 4 4 0 etc) undo with a central screw.
Thanks, Peter, but on this one, all I had to start with was a bare chassis, so the cylinders, boiler, and everything else is scratchbuilt by myself. As such, removing the cylinders hasn't given me any trouble. /DesktopModules/NTForums/themes/mls/emoticons/hehe.gif

Ken, it's been a loooooooooooooooong time since I've been into the B'Mann 0-4-0 but if I recall, those axles are split and you pull them apart from the inside.
Stan, do you know if there is any sort of keying or registration to keep the wheels quartered, or do they just slip into the central insulated portion? I probably won't mess with removing the wheels, but it's crossed my mind. Besides, it's always nice to know how to take something apart if I need to.
Also, if I can remember, the front axle is different from the back and it's not too convenient to take the inserts out.
Are the inserts different, or just the wheels & axles?
Also, do you know if the inserts are glued in, or just press fit?
To try to pry them out with a screwdriver or pull them with a pair of needle nose pliers may scar the spokes.
You solution stated in your signature line is probably the best....
That may be exactly what I'll have to do, Stan. If the insulators on the axles weren't plastic, I might just take a torch to the wheels, and burn the centers out!
Guess I can't play with fire on this one.
