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