Truck Side Frame

[cam]

I have a GP40 locomotive (Bachmann).  I have had this locomotive for approx two years and while in the process of cleaning and checking, I was not able to remove the Truck Side Frame from the gear box.  I can see how it should be done, but can not get enough Clarence to pass the tab.  Can you give me a hint as to remove the frame from the gear box?

I also noticed that the wires that connect the motor to the drive wheels were not attached to the wheel brushes and do not appear to ever been attached.  (this is only on one truck). 

Thanks Carl
