I have one of the top two two relief valves pictured in the link below. Forgot if it is one or two seperate valves. It is on a mortar mixer ( Grout Hog). The machine stop mixing from a mix that was to dry. Usually you can revese the direction of the paddles and it breaks free. This time the paddles turn but instead of mixing 3 bags of mortar it now only mixes 1/2 before hydraulics don't have enough power to turn.
When the hydraulics used to stop from overload there would be a screeching sound now it does not make that noise when it stops. Would that indicate the relief valve is not working?
Dealer was telling me it was the shear pin really (key on the shaft) from the blade shaft in the mixer that connect to the hydraulic drive motor. I doubt it would turn at all if that was the case.
It said to turm relief valve adjustment if you have the problem I have.:beatsme Can the relief valve brake? I know everything breaks but why would it need an adjustment? Does it reset itself if turned in?
Hope a tad of this makes sense. Thanks!

Adjust single relief on (1) 2-Spool Monoblock, Paddle relief on (2) 1-Spool Monoblock, or Main relief on 2-Spool Stack Valve by turning in clockwise all the way in.
