I really hesitated to post this question since it's a bit silly but I acquired a 2023 Lionel diesel and wanted to take off the shell to lubricate the motor and clean it if necessary. I tried to loosen the set screws on each end and they both move but the body will not come off the frame no matter how I try to loosen it up by pulling and pressing.
I have a 2032 Erie and the body came off easily. Is there another screw somewhere that I can't see or something else holding on the body? I know the 2023 was made a few years earlier than the 2032 but it appears to have the same setup, one each set screw on each end. Maybe a shot of PB Blaster on each screw will help loosen it upLOL?
