I purchased a new Lionel Thomas O gauge engine and a couple of cars earlier this year. I've done the normal (very) light oil on the crank pins and axles, but after many laps around the high speed race track, Thomas is starting to sound more like he has a Pulmore motor than a DC can motor. I can see some gearing in the front interior area, from a bottom view, but I cannot figure out how to get inside to grease it.
This pic below shows the screws I DID remove - removing the ones marked by 4 red arrows should have done it, but the bottom plastic plate they appear to be holding only came free on the front end, not the back. The screws marked with yellow arrows were also removed but did nothing and the green ones only held the coupler in place.... but I had to try them all!
In the 2nd pic below, (right and left bottom side views) I could not reach these screws to remove them, but they look like if released, the entire engine would drop out of the bottom - not necessarily what I want, but it may be the only way in?
A little help from those that have been there would be appreciated
