Intermountain SD40T-2 Decoder Install - Any Tips?

I'm about to take the leap and try to install my first DCC decoder into an Intermountain SD40T-2, and would appreciate any hints or suggestions.

I have a Digitrax DB166I0 decoder, kapton tape, tools, etc.

What is the best way to remove the shell without messing up the handrails and any other details?

Thanks!

 

One of the best N scale life hacks ever. This works for about 80% of all locos.

 

Intermountain shells are not very tight so they should come right off using Rick's steps.
For Kato and Atlas, Metro Red Lines' video describes a way to do it. I do all of my removals by hand.

 

Thanks for the info. Should be helpful!

 

Thanks for the help!
