    CAT 320D WITH SLOW HYDRAULIC MOVEMENTS A8F02378

    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...

    Dear all, I hope you are well. I'd like to know if anyone has the service card PS54810, as it's no longer available in the SIS system.

    CS54B prefix M5B, produces intense humming when compacting.

    Hello everyone, I hope you're all doing well! This time, I'm sharing a situation with a CS54B compactor. The machine emits a loud humming noise only when it's compacting, but when it's moving normally, without vibrating, it doesn't make any noise. I think it's the large bearings inside the drum...

    CAT Main Harness Part Number 336D

    Hello everyone! I hope you're all well. I need a hand. I need to find the part number for the wiring harness that connects the hydraulic pump pressure sensors, temperature sensors, and the hydraulic filter. It also connects to the PRV valve.

    CAT 416 L9P07254 air conditioning malfunction

    Hello, I'm having trouble with the air conditioning on my 416 L9P07254 backhoe. The system cools very well at 900 RPM, but when the engine speed is increased above 900 RPM, it stops cooling. When I stop the engine and restart it, it cools again. The system pressures are fine, and I haven't found...
