I have a number of MTH and Lionel engines purchased over the last 20 years. My desire is to keep all of them in good operating condition and I realize that as an engine ages, it requires more maintenance than is listed in the owners manual. Does anyone know of a good video that shows a more detailed maintenance of MTH or Lionel engine? Specifically covering but not limited to the following areas: cleaning(removing the old grease) and lubrication the truck gears, checking wires for areas of wear/exposure, smoke unit cleaning and re-wicking, traction tires-checking and replacing, battery replacement/check. The premise being that, "since I have the cover off, I might as well check the following". The challenge I'm really looking to address is taking my Father's 15 year old MTH PS2 5v engines that hasn't been run in 3 years, giving them some TLC, and having each one perform well. Oh, and yes, I do know to charge the battery before trying to run, thanks.
Additionally, do you have a "service list' that you use when working on your engines?
Thanks in advance for all who contribute.
