Looking for advice: My 773 (circa 1950) has a grease box underneath. None of my other locomotives have this and I don’t have the 773 instructions. When I remove the screw do I fill the compartment completely with grease? I always heed warnings not to over-lubricate, but in this case I don’t know what to do.
Your answer can be found HERE.
I would(and I do) substitute a modern synthetic like Lucas Red ‘N’ Tacky #2 for the Lionel lubricant specified, though.
