Sorry, wasn't trying to keep anything secret, just didn't have the camera when I replaced the smoke fan motors handy.
The tender:
How you have to rotate the drive wheels and then use a thin screwdriver to reach those front screws
The other 4 screws are pretty obvious
Thank you @Vernon Barry for the pictures and instructions !!!
Just curious, the coal bed cover (for the setting switches) has two wires with a connector. What is that for? an antenna embedded in the coal bed?
Interesting, the shell casting still shows MTH; part of the MTH tools purchased by Lionel ?
Dave explained how the wheelslip works in one of the videos. Both the engine and the tender have motors with encoders. Normally they just run in sync the exact same RPM. In wheelslip, the rear motor in the tender ramps up and moves more encoder pulses over a short but controlled acceleration and then resumes the exact same speed. The rear drives wheels do not have traction tires or grooves for traction tires.
One interesting note that just stuck out to me- both boards are tethered together, but also, both boards have the TMCC/Legacy radio antenna connected and used. Only the tender board has the switch for program/run. Obviously this engine has unique firmware and very specific programming for the boards, but also, each is kind of a complete "engine" with RF sections.

Sorry cross typing but yes, the tender too has the typical metal plate TMCC antenna (in the removable coal load to access the switches). What is unique is again, both have complete LCP2/LCP3 boards with RF section, and the antenna, but only the tender has the switches. So there is a lot going on in the firmware and across that multipin tether.
Lionel did put a lot of electronics- basically 2 engines worth, into this model. I am impressed.

From what I can see, the switches are 2 in 1 design where the 2 boards will both have their bluetooth and run/program handled through 1 switch. My guess is there are 2 wires running up to those switches for run/program for the front and rear board, as well as 2 wires for the front and rear board for the bluetooth on and off switch.
a lot going on in this engine. aside from the cool wheelslip my mth triplex smokes just as good and is easier to work on.
glad I kept mine and passed on the visionline one. not knocking those who got one. just did not want to go through what sean and vernon went through. especially on a brand new model.
