Lionel 027 Lehigh 627 Center Cab

[Anonymous]

I purchased a Lehigh 627 center cab engine on ebay. I was told that it runs but it doesn't. The engine is from 1956-57. I would like to repair it. It sits on the track and just buzzes. I replaced the e-unit but not sure I did it correctly. Is there a way that I can test the motor directly with the transformer to see if it works. Anyone have a wiring diagram for this unit?

Thanks,

Freddie: 

You will have to disconnect the E-unit from the motor before testing it (I recommend making a diagram of where the leads go, then unsoldering them),  Once this is done, connect a jumper from the ground to one motor brush, and connect the other motor brush to the magnet terminal and then to the third rail shoe.  This will wire the motor up with the wound field magnet in parallel with the armature commutator and, if the motor is in working order, the engine will move in one direction only.  Good luck! 

In a related question, the motor in my 627 has developed a case of Cajun Blackened Motor Windings and I need to find a replacement.  Does anybody have any suggestions?

(This is the one that I turned into a trolley freight motor; see http://cs.trains.com/TRCCS/forums/t/199238.aspx for more details.  I'd like to have it running by December 3 if possible; I'll be displaying trains at the Children's Train in Springdale, AR!) 

Thanks in advance!
