FAQ:
Q1: How to check hydraulic pump flow rate?
A: Use a flow meter connected to the pump’s outlet port, measure the flow under rated pressure, and compare it to the OEM specifications.
Q2: What is the difference between a main pump and a swing pump in Cat excavators?
A: The main pump supplies hydraulic power for overall movements (boom, arm, bucket), while the swing pump is dedicated to the excavator’s upper structure rotation.
Q3: Can Cat hydraulic pumps be repaired on-site?
A: Minor issues (e.g., seal replacement, fitting tightening) can be fixed on-site, but major damage (e.g., internal cylinder block wear) requires workshop disassembly and repair.
Q4: What is the OEM part number for the swing pump of Cat 374F?
A: The common swing pump part number for Cat 374F is 593-3840, a double piston pump.
Q5: Why does a hydraulic pump experience cavitation?
A: Cavitation is caused by low oil level, restricted suction lines, high oil viscosity at low temperatures, or a clogged suction filter.
Q6: Are Cat hydraulic pump parts interchangeable between different equipment models?
A: Only if the models share the same hydraulic system specifications; always verify with the parts manual or dealer before interchange.
