How to dismantle older engines (90’s)

[natoanjou]

Just got 2 used engines listed below. I need to dismantle enough to check cleanliness and maintenance if needed.
Cannot find manual for either.
Thanks!

They'll charge you for hardcopy. NW2 MANUAL or you can download it. https://www.usatrains.com/images/NW2.pdf I asked my friendly, local AI to find it.
