If you do, don't forget to order the Railsounds Lite PCB mount bracket. You will be glad you made your life easier.
And it goes without saying, but you'll want to make sure you have all the correct wire harnesses to attach the input power, volume pot, and speaker. As I recall, these are different connectors than what was used on the PCB which was originally installed.
I only have a few CC sets...I looked for years for the UP set and finally found one last summer on the forum. The best part it’s was located right in town in the next neighborhood ! I remember I took off early from work to go get it. Very smooth runner it’s been up on my small elevation for the past 5 months.
@Norton posted:Mark, did you move the spacer washer on the GG1 truck? If not the wheel flanges rub on the frame creating a lot of drag and overheating the motor and E unit.

Had a bit of time so I decided to look into this.
Below is an image of the Conventional Classics GG1. The truck on the right is loose, meaning I have removed the screws holding the roller and the motor.
With that said, what I found was brass/bronze washer on axels but no rubbing of the flange. Circled in red are the brass spacers and in yellow is the flange that is very close to rubbing, but does not look like it is actually hitting the frame.
The motor turns smooth, and the wheels seem to turn freely, but the unit does get hot.
Is this the area you are speaking about in your comment above or should I be looking at something else?
Thanks.

Charlie, this is the washer in question.
It is located around the screw that holds the truck to the motor. They have been found above the frame next to the motor. It should be located below the frame next to the truck. It gives added clearance so the wheel flanges don't rub on the frame.

Looking for it right now. Give me a few minutes.
Thanks Pete.

This is what I found.
The thin (.0155) washer on the motor side. I will move to the truck or under side and see if this makes any difference. As a side note, now that I understand what you are talking about, I feel I should see some visual marks on the bottom side of the frame but I don't see any. I do observe the clearance is very close from the edge of the flange to the bottom of the frame.
Thanks again Pete.

What about this? Could that have been caused by the flange rubbing?
The washer pictured above is listed as .034” thick.

Yes! 100% correct. I was looking at the wrong area. I thought that was the motor waring the paint.
So.. In my opinion, the washer I have is NOT enough to clear the flange rubbing. I will need to run to the hardware store tomorrow and pick up something a bit thicker. I have the unit running on a test stand now and I can feel the resistance of the wheel if I place a bit of downward pressure. Its clear to me now, that I did not pick up on this before (maybe because I did not run this locomotive that much).
I will let you know what my results are tomorrow. Again, my washer is .015 and that is too thin. I will pick up a few different sizes and let you know what works for me.
Thanks again Pete.
