On30 2-6-0 Christmas Engine 3 info

[Rivercoon]

I have an On30 2-6-0 Engine #3 from a North Pole Express set that is not working properly.  It moves slowly and bounces.  My guess is a bad gear. 
I do not know the model number of the engine. Where can I find a service sheet with a diagram and part numbers?  Right now I do not even know how to take it apart to get to the gears.

The exploded diagram for the On30 2.-6-0 can be found here:

You might also check the side rods to make sure nothing is binding if the loco is bouncing.

Thanks.  The rods are clear and run as smoothly as I've ever seen on this sort of engine.
Do you know if replacement gears are even available?  They are not parted out on the diagram.

Here are the gears in Bachmann's parts store for the On30 2-6-0 models:
