So, I'm confused. I thought the c01 variant was the one to get instead of 2878c02. Doesn't the c02 varient require the side pieces to keep the wheels on the shaft?

Are their part numbers for just the axle and wheel?

Can someone identify the bricklink numbers for the axle and wheel? I would want the version with the through hole wheel and matching axle. Thanks in advance.

So... did this idea die? It really is needed given the state of 9v motor availability.

Are these still available? I'm surprised there isn't a huge demand given the cost of 9v motors !

If the axle is that tight, I think I would chuck it in a drill and use some steel wool on it to shine it up and that may be all you need to have a nice fit. Given the fact the lego parts are for toys afterall, I wouldn't always expect exacting tolerances with a part like the axle.

Can someone tell me the technic brick number so I can order some off bricklink to experiment on?
