• Verify OEM part number to confirm the main hydraulic piston pump assembly fits, including the pump body, regulator, and servo valve components.
• New or remanufactured pumps must provide a hydraulic bench test report covering pressure, flow, case drain, and internal leakage.
• For remanufactured pumps, confirm new replacement of pistons, cylinder block, valve plate, slippers, retainer plate, bearings, and all seals.
• Inspect the pump housing for cracks and sand holes upon arrival. Keep port threads intact and seal ports to prevent contaminants.
• Secure the pump during transportation to avoid impact damage to the input shaft, ports, and precision valve parts.
• Clean the hydraulic tank and pipelines before installation, replace all hydraulic filters, and bleed air from the hydraulic system.
• Test pump pressure, flow, and regulator response after installation. Check for abnormal noise, overheating, oil leakage, engine bogging, and weak operation.
