• Verify OEM part number compatibility, including regulator and servo valve assembly
• Require hydraulic bench test report for pressure, flow, and case drain leakage
• For remanufactured units, confirm replacement of pistons, cylinder block, valve plate, slippers, bearings, and all seals
• Inspect pump housing for pores and cracks upon arrival
• Protect ports to prevent contaminants from entering pump cavity
• Secure pump properly during transportation to avoid damage to input shaft and port threads
• Clean hydraulic tank and pipelines before installation
• Replace all hydraulic filters and bleed air from system
• Test pump pressure and flow after installation
• Check regulator response and inspect for abnormal noise, oil leakage, and engine bogging
