Anyone Had a Legacy 6-11463 AC-12 #4291 Apart??

I can't help you, but was wondering if you were able to figure it out...?

Yes I did with the kind help of member Alex Malliae. He pointed me in the right direction and I got the smoke fan motor changed out and she's back up and running nicely again. It's too nice of an engine to leave gathering dust on a shelf!

It turns out the boiler separates right at the catwalk, and the upper half is easily removed revealing all the electronics and the smoke unit. I wish more steamers were built this way. I will post some pictures detailing which screws to remove later. Thanks Alex! I also corrected the Lionel item number in the OP, I had mis-typed it, duh.

Some of Lionel's newer big steam is really easy to work on, not like many of them.

As promised here are some pics of the dissasembled cabforward:

This shows the cab and boiler screws that need to be removed in pairs. Note that even if you don't need the cab off, it has to be removed to free up the front of the boiler.

Here is one of the pair of  screws to remove to free up the rear of the boiler:

Once you get the top off the boiler here is what you will see:

The MCRC board:

Smoke unit removed:

Dual smoke unit dissasembled:

This engine is a dream to work on once the boiler is removed. I wish they were all like this!!

Thanks for the pictures. I have a cab forward that jerks running forward and runs smoothly in reverse. Not knowing how to remove the boiler has fed my procrastination for too long now.

Roy now you have no excuses!

Hey, when it comes to procrastination, I can always find a way.

Thanks for posting all these; it would be a great help if stuff like this got shown more often. I appreciate your taking the time to do so, and am glad you got it going again. 👍
