CAT 320D WITH SLOW HYDRAULIC MOVEMENTS A8F02378

[PABFER.UY]

Dear all, I hope you are well.

I have this 320D with sluggish movements, but the diesel engine runs perfectly. Could it be a lack of calibration of the PRV (Power Steering Valve)? I tried to calibrate it, but I couldn't because the speed sensor is faulty.

The pressure of pump 1 is 3848 kPa, pump 2 is 4048 kPa, and the power shift pressure is 2438 kPa.

I hope you are well. I installed the speed sensor, and when calibrating the PRV, the pressure is constant, above 4000 kPa, and moving the calibration dial doesn't change the pressure. I noticed that the voltage reaching the PRV is the same as the alternator's 27V.
