Kato N scale Parts List Diagrams

I need some help. I’m looking for the exploded parts list for Kato N scale ES44DC (176-8936) and the SD70MAC (176-6307). I kinda know what parts I’m looking for but have no idea what they call them.

I was adding Microtrains couplers and the screw hole got enlarged so the couplers are loose. I tried using the clips but they kept falling out.
