Frequently Asked Questions
Q1: Are Cat hydraulic pumps compatible with non-Cat hydraulic oil?

They can be, but the oil must meet Cat's official specifications (e.g., Cat DEO Hydraulic Oil). Using unapproved oil may cause pump wear and void warranty.

Q2: What is the displacement of Cat pump part number 423-0097?

The 423-0097 axial piston pump has a displacement of approximately 65 cc/r, suitable for small excavators like 305.5E/306E.

Q3: How to identify a remanufactured Cat hydraulic pump?

Remanufactured pumps often have a "Reman" label, a unique part number suffix, and are certified by Cat to meet OEM performance standards.

Q4: What causes hydraulic pump oil leaks?

Leaks are typically caused by damaged seals/gaskets, loose fittings, cracked pump housing, or excessive system pressure.

Q5: Can a Cat hydraulic pump's rotation direction be reversed?

No, most Cat pumps are designed for fixed clockwise rotation (viewed from the drive shaft end), and reversing may cause internal damage.
