Youtube has several videos on repairing the gears that should be of help to you.

You don’t need a exploded drawing to replace the gears in the trucks. Robert West had the appropriate fix. I’ve just done this to a 20 year old Proto 2000 GP-9 and it runs like new. You can use grease on the gears or a tiny bit of LaBelle 107 oil. It doesn’t take much.

All I can suggest is to obtain an exploded drawing of the engine. They used to include one with the loco. ? Don’t Walthers now produce Proto 2000? You might contact them. Without a drawing, trying to describe dismantling by words is very difficult.

The axle gears that connect the two halves of the axles have probably cracked. This is a common issue with Proto 2000 GPs. If this is the case, you don’t need to even take off the body. On the bottom of the truck is a cover that snaps on. Use a small flat screwdriver to carefully pry it off, then you can remove the axles. Athearn part 60024 should be a direct replacement for the gears. Pull the axles apart, replace the gears, and reassemble. They will be a tight fit. Use an NMRA standards gauge to make make sure the wheels are in gauge. Then put them back in the truck, maybe add a tiny bit of grease to the gears, and snap the cover back on.
