Re: Dog Gear?

Isn't there 2 inherent weaknesses in a AM shifter used as a release mechanism given the forces the kicker could be putting on the dog. There is a small 3/32 pin through the dog to connect it to the internal pull shaft. If you use the air cylinder connector, it has a tiny bearing with an smaller roll pin running against it. Last I heard both pins have occasionally broken using 26lbs of pull force with a 3/4 air cylinder. Now I hear people have to use 1.5" air cylinders to trigger a release. Surely those pins are going to break.
