Link & Pin coupler conversion

I have many AMS 1:20.3 narrow gauge cars. I like the detail on them.

I recently got a logging disconnect. It has link & pin couplers for the disconnect and for connection to the train. That’s fine if you have a full logging train that’s all link and pin. In fact, I have a mine train and I converted one loco to link & pin to pull it.

However, I want this logging car to meld into my mixed freight consists. So, I need to add a coupler that is compatible with the AMS couplers to this car.

Here’s how to do it in one minute or less. First you buy a set of Kadee 908 couplers. Put all the hardware in your junk box. You only need the two heads.

In the photo below, here is the logging disconnect car with its receptacle and pin and the Kadee 908 coupler.

Next, I took a pair of wire cutters and cut off the “ears” - everything that sticks out on each side of the mounting boss.

Then, remove the pin and insert the Kadee coupler into the pocket. It will be a nice tight fit. Insert the pin and run your train.

You can always go back to the link & pin setup by pulling the pin and removing the Kadee. Or, for a permanent conversion, a 2-56 (black) bolt and nut would work, but you’d have to drill the bottom of the pin pocket. Or, you could drill and tap the bottom of the pocket and forget the 2-56 nut.
