I always wanted to try to see if i could put a F3 motor and running gear in a Alco postwar engine...
I used the original top plate and side plastic and basically put in on top of a F3 took more time to make the rear coupler than it did to put the motor and truck on..
Next will be the TMCC ... It takes such little power to get this to move and the lights on the cars are so dim Tmcc will help make it look brighter in the cars and still make the engine run a slower speed.. and I must say RuNS GREAT!
What I did was used the F3 motor as a hinge as shown by the screw driver and added the rear spring and clip . I put the shell on to make sure no problems ... daniel
