Ok, I know I asked this before. I know the valve is inside the pump somewhere and the pump is in the housing. Thank God for access covers I'm removing the access cover tonight to see what it looks like in there. I'm only getting a steady 620 - 650 lbs of pressure on the hydraulics and would like to see if I can adjust it with that relief valve. Especially since Andy and Ace seem to think I should be getting 800 to 1000 lbs out of it. I have a 3 in boar 8 in long piston that is vented on the rod side pushing up a New Holland 479. Now if I want I can get out there and lift on the bar and it will bring it up, but I don't care to have to do that all the time. I'm going to the NH dealer who sold me the unit and put the cylinder on brand new for me tomorrow bright and early to see if I can get a 4" cylinder to try on it but I'd still like to try the relief valve as well. So, for those of you who have managed to weed through all this, can you tell me what to look for (keeping in mind I'm totally ignorant) as the manuals aren't due in until " . . . . next Thursday or Friday or so". I really appreciate the input I've gotten so far and am grateful for all the help all of you give. Thanks once again (in advance) for helping in this scenario. Lugh

I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
