Grease, oil, or leave dry

[carpediem4570]

Well, this certainly has been an adventure.

I’m hard wiring a ihc mehano 2-8-2 mikado steam loco in ho.  This is my first attempt at doing so.

I’ve had a few issues along the way.  When I tested the motor, the wheels would not turn. 

I pulled the cover off the worm gear and cleaned out all the old grease and it is moving much better.

The worm gear and the two wheel gears are plastic.  Do I need to regrease them, oil them or leave them dry?

The wheel axle have no bearings and ride in a plastic slot.  The axles are brass.  Do these Ned to be greased, oiled or left dry.

Thank you in advance for the help.

Yes - clean thoroughly with IPA and a tooth brush, the old grease must come out - everywhere, it gets gummy. Make sure she is running good on DC,
then it should perform well. Yes also - light grease with synthetic super lube, and light oil on everything that moves.
