Hi everyone I have a Lionel 6-28225 SPSF SD40T-2 diesel locomotive and I'm trying to remove the front truck to replace the side frame. Does anyone know how to release the truck from the motor. This is an older locomotive from 2004-2005. I have never done this before and I can't replace the side frame while the truck is on the locomotive. I also own a K-Line K3688-4449C SP Daylight 4449 Locomotive and it runs great with the Cab-1 controller but when I try to use my Legacy controller I have to turn the controller many many times just to get it to move. Does anyone have any suggestion's on how to get this engine to run on the Legacy controller?
