Nice... now you are going to have everyone ask what is the PN of that motor.

A search garnered no printed or stamped motor ID, JDaddy. The appearance is like any other can I've seen but it's the absence of cogging that is important.
Here's the tender mid reassembly. Producing a trouble free upgrade installation involves the best practices of component positioning and wire dressing you can manage. Nowhere is this more important than when quarters are cramped. The tether flexibility outside the frame was crucial so the larger power feeds got heavier rubber coated wires. Now Bruce! You shouldn't use painters tape to secure wires! This stuff is automotive grade 3M #233 and stays put and pliant indefinitely. Umh, I see the RailSounds board but where's the speaker? It will reside in the engine cab...more on that later. The slight tilt in the main board was required so that the R4LC wouldn't contact the cast shell. While the Cruise Commander heat sinc holds the board proud of the truck king pin and C clip, at the back I fashioned a platform out of styrene to mount the RS board and gain height. Handle an RS board with extra caution and as infrequently as possible. Yeah, don't ask! Shell installed, there have been some details removed in preparation for future modifications, but let's get back to the electrical and mechanicals. An antenna was made from wire mess, stuff that is 1/2" square openings and soldered together. Form the wire to represent the shape of the coal load and solder on the antenna lead. A covering could be whatever floats your boat. Tape top and bottom will form a good base but make sure the edges are well insulated from the tender shell. I used thin foam rubber to wrap mine. At this stage it became possible to test the electricals in running mode. Did I get it right the first time? Stop laughing! My mind can't seem to process possitive polarity with TMCC ground. That's like doing things the British way!
I removed the slant railing for ones of my own making but I required new markers now to wire up and replace the old solid jeweled types. If anyone is interested in how I made those I can post a separate topic. The attention paid to positioning the new coil coupler helps the illusion of authenticity. I plan to do more work back there too. A side view to show the awesome lowrider look that Lionel engineered in. The coal load may get an extended coal bunker of the common type in PRR use. That's another future endeavor. The limiting chains on both trucks are a work in progress. On the main she now performs better than ever and this seems like the perfect opportunity to take a breather. Note the motor position low in the cab. A past installation using a flywheel mounted motor from a diesel looked ungainly and the sacrifice in operating characteristics by swapping out with the printer motor seemed negligible. Back to it next week.

Over the last week I have plugged away at changing out details on the engine. The bell needed a better representation of what was commonly found on a B6. The original bell was a bit too Plain Jane and the hanger better suited to a K4 Here's the replacement installed...
LED replaced incandescent up front. I removed the solid jeweled class lights, unnecessary on a switcher.
Modifications in this shot were the addition of tread plate on the running boards and dome access steps. the steps were easily glued and painted in place whereas the running boards were pre-shaped to fit then sprayed before fastening. Hand rails and stanchions were scratched from steel wire to fit the original stanchion holes. Sleeves of brass tubing and shrink tube fill the oversized stanchion holes an small nuts cover these adaptations.
The undersized pump was ground down enough to form a flat edge, top and bottom........ A larger one was glued in place and painted, adding a little more interest to an otherwise plain looking boiler. My atrocious photograph and lack of detailed instruction is hopefully sufficient to impart the simplicity of this project. I attempt to use the commonest of tools that any basic tinkerer will have on hand. Next step the cab.

This engine is coming together nicely. Great job!

What a rebuild Bruce!! I like the exterior upgrades too. "Low rider" tender is way cool!
Gary.

Thanks gents
While I clean up the kitchen table ....er ....work bench, the reassembled project has been getting some run time on the layout. If I can learn how to post a video I will. The puffer smoke unit now works overtime at a full 18V which shows off the steam chest exhaust more prominently.

Bruce, you did a fabulous job on this locomotive. 👍 I'm looking forward to seeing the video.
