A11VO130 / A4VG56 hydraulic main piston pump assembly for CAT M318 excavators. Compatible with OEM part numbers 0R-8674, 111-3727, and 139-9530. This assembly includes the pump body, regulator, and servo valve components.
Procurement Guidelines
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.
Purchasing Recommendations
Option
Key Considerations
Original New
Stable performance, high price, long lead time
OEM New
Export preferred, request factory pressure test report
Rebuilt
Budget-friendly, confirm warranty terms
Used Pump
High failure risk, not recommended for export
Additional Notes
Test main pump pressure first to rule out control valve and pilot system faults.
Purchase hydraulic oil, return filter, suction filter, and seal kit together.
Export packing: fumigated wooden crate with test report.
Warranty excludes damage caused by oil contamination, air ingress, and improper installation.
