Lionel's plastic-case motors that were developed for the Scout line in 1948 and continued through the 1950s have a reputation as being "disposable" motors - unreliable and nearly impossible to work on.
Having purchased my first such motor recently, a #1110 2-4-2, I decided to disassemble, clean, and lube one to see how difficult it actually is.
Armed with a few parts diagrams, I found the task not nearly as daunting as I was told. Follow along with me step-by-step!
**An interesting tidbit I did not mention in the video is this locomotive is a bit of a "Frankenstein". I established in a previous video that the shell in a 1951-52 model with the outline of the #6110 smoke hole clearly visible. However, this motor is a 1001-M, which was only made in 1948-49. Somewhere along the line, the motor was swapped out.**
