Joe, Thanks for the response to my questions. One other question. Is the only way to gain access to the drivers as shown in the photos is take the engine entirely apart?
This looks like a daunting project. I am good at taking stuff apart. I am not so good at getting it back together. Let me modify that. I get it back together but it doesn't always work the way it did before I took it apart.
I will have to get the engine out of its box under the layout and take a look at it. Thanks for information.
Joe
