The whells go on the yellow rods then it is driven from the yellow gear.

I found a way of holding the yellow gear on without the wire but it does require a broken rod.

 I posted something very similar a while ago (here: ).  Instead of using wire I modified (drilled a hole in) the yellow gear.  Your cage requires more pieces, but the additional structure may make it sturdier, I'd have to build one to find out.
