FAQ:
Q1: Are Cat hydraulic pumps compatible with biodegradable hydraulic oil?
A: Yes, but only if the oil meets Cat’s specifications and is compatible with the pump’s seal materials; consult a dealer for recommendations.
Q2: What is the pilot pressure range for Cat excavator hydraulic systems?
A: The typical pilot pressure range is 3–5 MPa, providing stable control signal pressure for the operation valves.
Q3: How to disassemble a Cat axial piston pump?
A: Follow the official disassembly manual, use specialized tools, mark component positions during disassembly, and clean all parts thoroughly to avoid contamination.
Q4: What is the part number for the main pump of Cat 349 series?
A: The main pump part number for Cat 349 series is 295-9426, a high-pressure axial piston pump.
Q5: Can a damaged hydraulic pump shaft be repaired?
A: Minor shaft wear can be repaired via plating or grinding, but severe damage (e.g., bending, cracking) requires shaft replacement or pump remanufacturing.
Q6: What is the role of a charge pump in Cat variable-displacement pumps?
A: The charge pump supplies low-pressure oil to lubricate internal pump components and maintain control chamber pressure for displacement adjustment.
