FAQ:

Q1: How to extend the service life of a Cat hydraulic pump?

A: Replace hydraulic oil and filters per the maintenance schedule, keep the system sealed to avoid contamination, monitor operating temperature (50–80°C optimal), and avoid dry starts or prolonged no-load high-speed operation.

Q2: Why is part number 487-6207 not suitable for Cat excavators over 3 tons?

A: 487-6207 is designed for mini-excavators (1–3 tons) with a small displacement that cannot meet the high-power demands of larger excavators.

Q3: What is the difference between a Cat pump’s OEM part number and its replacement number?

A: The OEM number is the original factory code, while replacement numbers (often prefixed with “CA-”) are for upgraded/remanufactured versions that are fully compatible with the original equipment.

Q4: How to troubleshoot abnormal noise from a Cat hydraulic pump?

A: Check for low oil level (cavitation noise), blocked/leaking suction lines (air intake), misaligned/worn couplings (mechanical noise), or internal pump wear (scraping noise requiring repair).

Q5: What is the typical rated pressure range for Cat excavator main hydraulic pumps?

A: Most Cat excavator main pumps have a rated pressure range of 28–38 MPa, varying by equipment size and application.
