The pump is making a loud Whirr noise, the discharge line has a strong vibration in it.

My son says the same, "just take it apart". He is across the country right now so he cannot help me. I have replaced the main shaft and bearings in one before. I have never taken apart the stroke control valve and outlet valve. I am concerned about getting them adjusted right. JDH-19 looks like the tool I need for the outlet valve and the stroke control valve may be just setting the pressure. Any comments about adjusting those two valves? Yes, the rest of it looks reasonably straight forward. Thanks for your comments. Paul

There are 8 each of the inlet & outlet valves. Setting stroke control valve requires a 3000# gauge and adjust on tractor with engine running.

Again, thanks for your response. See the page attached. The valve on the left I believe is the stroke control valve and it is adjusted based on the pressure the pump develops as you said. The valve on the right is my concern, from this page I understand it needs adjustment as well. What can you tell me to adjust this valve. I am thinking I will go to the dealership and see if I can borrow JDH-19. What have you done to adjust this valve in the past? Paul

Sorry but TOO much water has run under the bridge for me to remember. Maybe Tim,Tech 7,Cliff or someone else will help you.
