I replied to you, Kaleb, with this question back on the 10th. I replied to 3 people in 1 message, though, so I'm sure you did not see it. Either you or Marshall seems to be right on this. How would I check these valves? I have been inside many Caterpillar 3406 pumps, but haven't a clue what to do inside this one. What tools do I need? What extra parts (o-rings, seals?). It looks like ~$200 to just throw some valves at it, so I just might.
