FAQ:
Q1: What is the function of a relief valve in a Cat hydraulic pump system?
A: The relief valve limits the maximum system pressure, preventing overload damage to the pump and other hydraulic components.
Q2: How to identify a genuine Cat hydraulic pump?
A: Genuine pumps have a Cat logo, clear OEM part number marking, and a serial number that can be verified via the Cat official system.
Q3: What is the application of Cat gear pump part number 560-0886?
A: 560-0886 is a pilot gear pump suitable for all series of Cat mini and small excavators.
Q4: Why does a hydraulic pump produce excessive heat?
A: Excessive heat is caused by system pressure exceeding ratings, internal pump friction (wear), low oil level, or using oil with incorrect viscosity.
Q5: Can a Cat hydraulic pump be adjusted for higher flow rate?
