1. Key Features & Benefits

• HPK060 series – Hitachi’s 13‑ton class hydraulic workhorse – This pump (OEM 9317963 / YB6000187 / YB60000886, model HPK060) is a variable displacement axial piston pump engineered by Hitachi for the ZAX130‑5A, ZX130‑5A, and compatible 13‑ton class excavators. It powers the boom, arm, bucket, swing, and travel circuits with the precise flow and high pressure required for fast cycle times, smooth multi‑function operation, and reliable performance in heavy‑duty construction, quarrying, and utility work.

• Professionally remanufactured to Hitachi OEM specifications – This pump has been completely disassembled, cleaned, crack‑inspected, and rebuilt in our ISO‑certified facility. All wear components – cylinder block, piston assemblies, valve plate, swashplate, bearings, and seals – are replaced with new, high‑quality parts. The result is performance and reliability comparable to a new unit at a fraction of the cost.

• Substantial flow for 13‑ton class performance – The ZAX130‑5A hydraulic system features two variable displacement axial piston main pumps delivering a maximum combined flow of 2 × 117 L/min (234 L/min total) . The HPK060 is engineered to handle this flow, providing the hydraulic power needed for fast cycle times, high bucket fill factors, and responsive multi‑function operation.

• High‑pressure capability for demanding work – Rated for working hydraulic oil circuit pressure of 34.3 MPa (≈4,975 psi) , with walking and swing circuits also rated at 34.3 MPa and 32.3 MPa respectively. This pressure capability delivers consistent digging force (104 kN bucket digging force), swing torque, and travel power hour after hour in the most demanding applications.

• Integrated load‑sensing power control – The factory HIOSIII hydraulic system control is fully rebuilt and calibrated. It continuously matches pump output to actual working demand, reducing fuel consumption, preventing engine stall under sudden load, and extending the life of the entire hydraulic system.

• New bearings and precision‑ground wear surfaces – All bearings are replaced – never reused. The cylinder block and valve plate are re‑ground to restore flatness, ensuring minimal internal leakage, cooler oil, and better efficiency.

• Tandem variable displacement axial piston + gear pump design – The ZAX130‑5A hydraulic system uses 2 variable displacement axial piston pumps + 1 gear pump (pilot circuit). The pilot pump delivers 33.6 L/min at 4.0 MPa. The main pumps are rebuilt to original Hitachi specifications, ensuring seamless integration with the excavator’s hydraulic architecture.

• Direct bolt‑on replacement – Mounting flange, drive shaft spline, and hydraulic port configurations are restored to original Hitachi specifications. No modifications, no adapters – your mechanic unbolts the old pump and bolts this one in.

• Hydraulic test stand validated – Each remanufactured pump is run on a test stand to verify rated pressure (34.3 MPa), flow (2 × 117 L/min), case drain leakage, and control response. A test report is available upon request.

• Pre‑shipment visual verification – We send you clear, high‑resolution photographs of the actual pump (mounting flange, splines, port threads, castings) before packing. You approve – we ship. Never blind.

• Fast delivery – 5–8 working days from our Guangzhou warehouse. Monthly capacity 300 units.

2. Applications

The remanufactured Hitachi HPK060 main pump is the power source for ZAX130‑5A and 13‑ton class excavators used across a wide range of demanding job sites:

• Urban construction & utilities – Sidewalk repairs, water and gas line trenching, fibre‑optic cable installation, and small‑scale demolition in tight access spaces. The pump’s load‑sensing control provides precise, “fine‑touch” flow for delicate digging near existing utilities, while the high‑pressure capability (34.3 MPa) offers enough power for breaking compacted surfaces. The 13‑ton class machine with its 2 × 117 L/min flow handles these jobs with speed and efficiency.

• Residential & commercial development – Foundation digging, basement excavation, retaining walls, grading, and site preparation. The pump’s smooth response and quiet operation are essential for noise‑sensitive neighbourhoods. With a maximum flow of 234 L/min, the machine maintains fast cycle times even in multi‑function operations – booming, swinging, and travelling simultaneously without power loss.

• Road & bridge construction – Shoulder repairs, drainage installation, guardrail replacement, and slope stabilisation. The pump’s ability to maintain consistent flow under varying loads ensures the excavator performs reliably throughout long shifts in exposed conditions. The ZAX130‑5A’s 70% gradeability is supported by the pump’s robust torque delivery.

• Quarrying & aggregates – Loading trucks, stockpile management, and material handling in abrasive dust conditions. The corrosion‑resistant metal body withstands harsh environments, while the high‑pressure tolerance ensures consistent performance even under extreme loads. The 104 kN bucket digging force is directly enabled by the pump’s 34.3 MPa pressure output.

• Mining support – Site cleanup, road maintenance, drainage works, and equipment pad grading. A remanufactured pump with new bearings and seals provides predictable service life (3,000–5,000 hours) – avoiding costly unplanned downtime in remote mine sites.

• Equipment rental fleet – 13‑ton excavators are among the most frequently rented machines. A remanufactured HPK060 offers predictable performance at a cost that makes proactive replacement financially sensible – avoiding costly mid‑rental failures, towing bills, and customer complaints.

• Forestry & vegetation clearance – Steep slopes, fallen timber, hidden obstacles. The integral power control prevents engine stall under sudden load spikes, maintaining consistent power for saws, grapples, and mulchers. The pump’s 70% gradeability support ensures reliable performance on challenging terrain.

• Agriculture & land management – Drainage ditch cleaning, irrigation trenching, pond maintenance, and fence post holes. The pump’s adjustable flow characteristics provide the versatility needed for both delicate landscaping and heavy agricultural attachments.

3. Why Choose Hongtengda Parts – Remanufacturing That Actually Works

Many hydraulic shops offer “rebuilt” pumps. They disassemble, replace O‑rings, add new paint, and call it done. The cylinder block remains scored. The valve plate remains warped. The bearings remain fatigue‑cracked. Within 500–1,000 hours, internal leakage returns, oil temperature climbs, and you lose power again.

Our remanufacturing is different. We replace what is worn, not just what leaks.

Our 6‑step process:

1. Complete disassembly – Pump stripped to every component: cylinder block, pistons, valve plate, swashplate, bearings, shaft, housing, control valves.

2. Cleaning & crack inspection – All parts cleaned, critical castings dye‑penetrant inspected. Irreparable parts scrapped.

3. Wear component replacement – All seals, O‑rings, bearings, gaskets replaced. Cylinder block and valve plate re‑ground to original flatness. Piston assemblies replaced as matched set if worn. Swashplate reconditioned.

4. Precision reassembly – Assembled using OEM torque specs. Clearance tolerances verified.

5. Hydraulic test stand validation – Tested for rated pressure (34.3 MPa), flow (2 × 117 L/min), case drain leakage, and load‑sensing response. Test report available.

6. Final quality check & packaging – Painted, port caps fitted, packed in heavy‑duty wooden case.

What you are buying: A pump with new bearings, new seals, ground wear surfaces – restored to OEM performance. Not a band‑aid.

What you are not buying: A used pump with fresh paint and a set of O‑rings.

Critical installation tip for the HPK060 remanufactured pump:
– Case drain line must be unrestricted. Blow compressed air through it before connecting. A blocked drain will blow the shaft seal instantly on first start.
– Before installing the remanufactured pump, flush the entire hydraulic system and replace all filters. Contaminants from the failed pump will destroy a remanufactured unit just as quickly as a new one.
– Use new O‑rings and sealing washers on every hydraulic connection. Reused seals guarantee leaks.
– After installation, run the engine at low idle for 2–3 minutes with the pump in neutral, then slowly cycle each function (boom, arm, bucket, swing, travel) to purge air from the system.
– Check pump alignment with the engine flywheel housing – misalignment causes premature bearing failure and shaft seal leakage.
