When I said early on that I had checked the relief valve, it was the boom circuit relief valve that I checked. I didn't realize that there were two relief valves until I went through the control valve drawings trying to figure out if I could tackle the rebuild. The main relief valve had a small piece of debris stuck in it. I'm now seeing about 2700 psi at the aux connectors. However, the boom is still jerky when I raise it. I greased everything up and it's still not smooth. It goes down perfectly smoothly so I'm thinking that this is a hydraulic issue and not mechanical binding. If I engage the aux hydraulics at the same time I raise the boom, the pressure drops to about 1000 psi, but it is stable. The boom does go all the way up, just not smoothly. Any ideas on this?</p></blockquote><p></p>
