Correct, this is the second time that it has broke the cam so there is a ton of load on it or something strange like that causing it.
Are they driving the pump off the rear of the cam? Straight cut gears or angle?

PDD had some trouble on their Cummins breaking the nose off the cam when running a big pump. From what I remember they think the pump puts enough strain on the cam gear and puts a twisting load on it
