I am going to go over coupler mounting height again and again, until I stop seeing or hearing about peoples conversion video’s posted on the internet that show people mounting couplers at the incorrect coupler mounting height on “how to videos”. Couplers barely hooked together and then bending the trip pin is not acceptable; even if the coupler is off 20 to 30 thousands checked with a coupler height gauge is not “good enough” for trouble free operation.
