    Hi all, I have a pair of Athearn SD40-2s that have the removable coupler boxes and I was wondering if there was a way or is it possible to put Kadee coupler boxes were the athearn ones go.
    any suggestions or ideas will be appreciated.

    Our club just ordered two Athearn SD40's last September. I replaced the stock couplers with Kadee #5's without changing the coupler pockets. After re-reading your post, maybe you have an older version with different coupler's. Kadee has a website that I believe lists which couplers go with most of the major manufacturers loco's.

    Athearn's SD40-2s have several different vintages...

    Mine are the old Blue-Box SD40-2s with the coupler mounting tab positioned too low, and they required underset #47 Kadee couplers. I had to drill #50 holes on the coupler-mounting tabs and tap them for 2-56 screws to mount the Kadee #47s.

    If you have a newer-vintage Athearn SD40-2, it might have the coupler mount at the right height to take a standard #5 Kadee.

    They looked like they would fit, I just didn't know if they would fit in the coupler pockets before I went out and bought em. Thanks for the help :)

    Tom, I had recently bought a new SD40-2 not to long ago, it did come in a blue box. It has the diesel engine on the front if that matters. And my other one is older but it has the same. There pretty new.

    Sounds to me like you got the ones that has the coupler mount tab at the right height. As Jim says, the Kadee #5s should work on your loco. Give it a shot. :thumb:

    I have two Athearn BB SD40-2's and have #5's on both of them.

    The #5s were a drop in fit in the one I just got:thumb:
