we had similar problems too, to get the bearing on, we used a peice of pvc pipe the same size as the shaft and hit it with a mallet numerous times.

we also had problems getting the gear on to the CIM shaft

also, did anyone else notice that the larger gear that is supposed to "rest" against the roll pin is very loose on the hex shaft?

It seems like these transmissions are just all around crap.
