this problem with the Scale Accumates because the scale draft gear box is too narrow to allow the coupler halves to separate far enough to lock. I have seen this on KD 5s as well. In this case it is caused by wear on the knuckle stop on the side of the coupler. The stop gets worn down sufficiently to allow the heel of the knuckle to slide slightly over it and either jam or stick very briefly. I can often fix this by using very fine needle nose pliers to slightly bend the bottom corner of the heel on the knuckle inward so that it once again will hit the stop firmly and not slide past it. regards, Andy Miller

On Behalf Of Denny Anspach Sent: Tuesday, October 11, 2005 1:20 PM I have heard before of the occasional scissors-like splitting of the Accumates when being pushed. I have had some occasional issues with Kadee 5s under the same circumstances (the coupler knuckles are pushed open, and for some reason do not close fast enough when the pressure is released) but this is has not been a memorable issue for me.
