Andy, thanks for this 3 part series. After many years I decided to break out my dad’s old train set, which worked right out of storage, but then decided to do some long overdue maintenance. This process discovered that the brushes needed replacement, armature needed cleaning and broken E-unit fingers. I bought all the replacement parts and your video greatly helped me reassemble the E-unit and get the locomotive working better than ever. I gotta say that aligning 2 fingerboards, barrel and alignment pin was pretty challenging.
Looks like a very tricky work. That needs a lot of knowledge and patience. I understand it is not easy to work with the unit an also let the image of the video to be clear. So I will suggest to have some kind of drawing to make clear what you are trying to repair. I love this trains, they have been part of my life. In recent years I bought in eBay a Santa Fe F-3 2343 It is running. I’m amazed the way it was constructed. Built for life !
I found that a small center punch on the side of the spacer bar. Set the center punch on the middle of end of the spacer bar and tap it lightly with a small ball pen Hammer. It will spread out the metal just a tiny bit. That will keep it together.
Those pliers at the end. I think would be lot better a device that closes with the action of a screw, to put only the correct amount of pressure to close the unit; no more. With the pliers te pressure can be excessive and I think, it can be ruined more easily. Just an opinion.
There are no screws in the e unit. Fixing one is a tricky operation especially lining up all the tiny parts at the end and then snapping them shut. Once you do a couple however, it's like riding a bike or soldering. You never forget how to do it.

Great informative video, conducted with a charming, friendly narrative. Thanks Andy.

I hope you do a video of repairing that pesky motor
