FAQ:
Q1: What SAE mounting standards are used for Cat hydraulic pumps?
A: Common standards include SAE A (mini-excavators/pilot pumps), SAE B (small excavators/loaders), and SAE C/D (large excavators/mining equipment), compliant with SAE J744 specifications.
Q2: Are Cat hydraulic pumps compatible with non-Cat hydraulic oil?
A: 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.
Q3: What is the displacement of Cat pump part number 423-0097?
A: The 423-0097 axial piston pump has a displacement of approximately 65 cc/r, suitable for small excavators like 305.5E/306E.
Q4: How to identify a remanufactured Cat hydraulic pump?
A: Remanufactured pumps often have a “Reman” label, a unique part number suffix, and are certified by Cat to meet OEM performance standards.
Q5: What causes hydraulic pump oil leaks?
A: Leaks are typically caused by damaged seals/gaskets, loose fittings, cracked pump housing, or excessive system pressure.
