Yes, the inside pulley half is securely on its hub and fits on the woodruff 
key on the
generator shaft, but its a little loose and slightly warped when spun. Could 
a bent inside pully
half cause the commutator to spin out of round?

When I removed the generator, I noticed that I didn't put on any spacers on 
the outside
on the pully. Without them the pully halfs never fully tightened. I'll try 
again with them
on.
