Notes:
Don Thompson shared tips how to disassemble and re-assemble this engine. This is an advanced topic, so take care. The piping is fragile. The LEDs in the headlights are molded into the light housings and are not serviceable.
You need a 1.6mm wrench to remove the side rods from driver #4 (available from Dave's Twacks & Twains). The delrin bottom chassis cover/brake hanger has flat head Phillips screws, and the two delrin injectors are a press fit and need to be detached.
Once removed, you are exposing a flexible printed circuit board that brings power to the headlight, optical detector of the chuff count, smoke unit, and both rail pickups. This unplugs under the cab.
When you lift out driver #4, do not forget that there are two phosphor bronze pick-up pins touching the back of the driver. They are spring-loaded and there are no replacements!
As far as quartering the one driver, should you need to install a new gear, use a carbide scribe and scratch the axle end and driver so that you can line that up as you press the driver back on the axle.
