A few months back I made up a hydraulic pressure gauge set up to check the pressure on my B2650. There was not any issues, I just wanted to know. It was 200 psi low from the max of 2400- 2450 psi. I decided to shim the relief valve to get it right close to the max because that is just the way I am. Also the spool for the bucket always was just a touch sticky. The boom spool was fine. My dealer said he would take care of it, but I thought today was a good day to tackle and learn something as I have never been in to a loader valve. I removed the right rear wheel, and then removed all of the lines to the loader valve, and then removed the valve. First thing i did was shim the relief valve out .015, as someone else had posted that would do right about 200 psi on my tractor. This is why it pays to get the shop manual as I did when I bought my tractor to be able to take on project like this. I then took the spools out, and inspected them. They were clean as a whistle, not a spec of crud or moisture. Which was good. The only thing I could figure for the bucket spool being a little sticky was the top seal is about a 1/2" long and might be a little drag if dry. I put a little white lube inside the seals and reassembled the spools into the valve. I then put every thing back together. After firing it up, letting it warm up, and cycling the hydraulics, The pressure came up 175 psi, to be at 2425 psi, so perfect. The white lube seemed to do the trick on the spools also, as they are both smooth as silk now. Good day in the heated shop, and I learned a little more about my tractor.
