HO-Scale Intermountain SD40-2W prior to TCS IB-MB2 and WOW121-Diesel decoder installation
In order to remove the shell, we must first remove the front and rear couplers screws, the couplers and their housings.
With the couplers and their housings removed, the shell can be lifted up and off of the locomotives chassis.
Above is a view of the chassis with the shell removed
Cut and remove the fasteners that hold the wires in place and identify the wiring layout.
Remove 4 screws as indicated in red, setting them aside for reinstallation later.
Remove the original lighting board and being careful to preserve the plugs, unclip the connectors
as well as the original speaker housing by removing the two screws on either side of it as indicated above.
Uitlizing the original screws, attach the 1B-MB2 motherboard to the chassis, the plug in the original connectors onto the motherboard in
the appropriate locations as per the included wiring guide. With the 35 x 16mm speaker wired and mounted into the INT-SH1 enclosure,
using the 2 original screws, attach the assembly to the frame. Plug in the WOW121 diesel decoder.
To ensure a neat and tidy appearance and minimize the chance of pinched wires and shorts when
inserting them into the shell, lace the wires into a harness.
Finally, place the locomotives shell back on and reintsall the front and rear couplers and their housings. With this installation, you can independently control the front and rear headlights and marker numberboard lights.
You have now installed a TCS IB-MB2 with a built in KA2 Keep-Alive™ and WOW121-Diesel decoder into your HO-Scale Intermountain SD40-2W.
