How to adjust hydraulic pressure on a ck2510

Everhard · Jun 16, 2023

So I finally got around to hooking up a gauge to my ck2510 and checked the hydraulic pressure, it's maxed at 2100psi.
So... The question - how to adjust it to get it closer to what the max can\should be which I believe is +-2500psi.
I know on other models the pressure relief is located at block where the rear remotes are located, wondering if that's the case for my tractor, if anyone has any further info.. Be much appreciated. Thanks!

Where did you measured the pressure? What pressure are you trying to increase? Loader? Remotes? Also, what does the manual say regarding the pressure?

Each valve (Loader, remotes, 3pt) will have it's own relief valve. The first valve in the circuit (usually the loader one) dictates the system pressure for the rest of the hydraulic circuit. Which means increasing the relief pressure on the valves further down the line, won't have any effect at all as it's still limited by the first valve in the circuit.

Sometimes there is an hydraulic block after the pump where the loader valve connects too. That will be the first relief valve in the circuit, therefore the main one. I don't know if that's the case on your CK2510.

Anyway, keep in mind that it's very easy to blow up things by playing with relief valves. Definitely have your gauge there, monitor the pressure and don't go over the max pressure said on the manual.
