I received two of the new BN SD40's yesterday and added a Kadee coupler to the front of one unit to see how they look. I think they look great! Lionel did a good job by providing the Kadee mounts on their new kinematic pilot. I'm very satisfied with these units. They are very detailed, minimal gaps, trucks tucked in nice, thinner handrail wires, fuel tank is low to the track...basically just like the prototype. They run smooth and as usual sound great. I like the horn much better on these than the previous SD40-2 which sounds like a goose that swallowed a harmonic. The idle and revving sounds are well done. There is no wobble from the traction tires and it feels like they can pull more cars than I can put on the track .
The Kadee was easy to mount but you do have to remove the operating coupler. Photos below. I chose to cut the wires at the coupler which can be solder back later if needed. There may be a connector inside the engine to remove the whole assembly, but I was lazy and did not want to remove the shell. I've added some photos of the assembly.
The only negative was that the front railing assembly broke off when I tried to straighten the railing. It is just glued to the face of the deck with not much support. It was not glued very well to begin with. I had to clean the dried glue off an re-glued using all the available surface area. It seems stronger now. It will stay in place but be for be forewarned that if you try to straighten the rail it may break off. I recommend pressing in on the base as you bend the rail. If it breaks, its easy to re-glue.
Thanks,
Next are some photos of how to add the Kadee. This or something like this will be on the next video.
First remove the truck by turning 90 degrees and lifting
I unscrewed the coupler and cut the wires right were the black wire is soldered onto the copper coil wire.
I then put electrical tape on the ends and secured the loose wire under the metal braces.
They included a mounting block/spacer.
You first screw on the Kadee to the mounting block before applying to the pilot.
Note: There are some springs included and I don't know what for. They may be spares for the kinematic pilot.
Then mount the block onto the pilot.
Use the small screws to mount to the pilot and your done!. Put the truck back and off you go.
