विवरण जानकारी

1. प्रमुख विशेषताएँ और लाभ

• 按照日立 OEM 标准进行专业再制造 – This YB60000068 / YB60000069 tandem main hydraulic pump has been fully disassembled, cleaned, crack‑inspected, and rebuilt in our ISO‑certified facility in China. All worn components – cylinder block, piston assemblies, valve plate, swashplate, bearings, seals – are replaced with new, high‑quality parts. The result is pump performance and reliability comparable to a new genuine unit at a fraction of the cost.

• Original Hitachi twin‑pump architecture for ZAX200‑5G – The YB60000068 and YB60000069 are the two main pump sections that work together on the ZAX200‑5G (20‑ton class excavator). This variable displacement tandem axial piston design powers travel, swing, boom, arm, and bucket circuits independently, ensuring smooth, coordinated multi‑function operation without internal flow loss.

• Restored flow and pressure for 20‑ton class work – After remanufacturing, these pumps deliver rated working pressure up to 31.9 MPa (≈4,630 psi) and a combined flow of approximately 2 × 200 L/min. Your ZAX200‑5G regains full digging force, fast cycle times, responsive swing, and powerful travel.

• 集成式负载敏感功率控制 – The rebuilt pumps retain the factory power control (load‑sensing) system, which continuously matches output to actual working demand. This reduces fuel consumption, prevents engine stall under sudden load, and extends hydraulic system life. The integral pilot gear pump is also rebuilt to supply the control circuit.

• 高性价比的新品替代方案 – A new genuine Hitachi main pump set for a 20‑ton excavator is a major expense. Our remanufactured YB60000068 / YB60000069 set gives you the same fit, form, and function at a significantly lower price, without sacrificing reliability. Each pump is tested on a hydraulic test stand before dispatch.

• 直接螺栓固定替换 – Mounting flanges, drive shaft splines, and hydraulic port configurations are restored to original Hitachi specifications. No modifications, no adapters, no fabrication – your mechanic unbolts the old pumps and bolts these in.

• 发货前可视化确认 – Before packing, we send you detailed high‑resolution photographs of the actual remanufactured units (mounting flanges, splines, port threads, castings, overall condition). You approve shipment – we never ship blind.

• त्वरित डिलीवरी – 5–8 working days lead time from our Guangzhou warehouse. Monthly supply capacity of 300 sets, available for single‑set or bulk orders.

2. अनुप्रयोग

The remanufactured Hitachi YB60000068 / YB60000069 main pump set is ideal for ZAX200‑5G and 20‑ton class excavators used in demanding job sites:

• 重型建筑与基础设施 – Highway excavations, dam building, bridge footings, large‑scale earthmoving. The restored tandem pumps deliver simultaneous boom, arm, and travel power without internal leakage – no power fade, no sluggish response, even on long shifts.

• 采石与骨料生产 – Loading trucks, stockpile management, and material handling in abrasive dust conditions. New bearings, seals, and wear plates ensure the pumps survive where worn units fail. Consistent flow and pressure mean faster cycle times and lower fuel consumption.

• Mining support – Site cleanup, road maintenance, drainage works, and equipment pad grading. The load‑sensing control reduces fuel burn during light‑duty cycles, saving money over thousands of operating hours.

• 拆除与废料处理 – Shock loads and vibration are routine. Our remanufacturing process replaces all wear components, restoring the pumps‘ ability to withstand harsh, unpredictable conditions.

• 设备租赁车队 – 20‑ton excavators are rental workhorses. A remanufactured pump set offers predictable service life (3,000–5,000 hours) at a cost that makes proactive replacement financially sensible – avoiding costly mid‑rental failures, towing bills, and customer complaints.

• 林业与土地清理 – Steep slopes, fallen timber, hidden obstacles. The integral power control prevents engine stall under sudden load spikes, maintaining consistent hydraulic power for saws, grapples, and mulchers.

3. स्टॉक उपलब्धता – होंगतेनगदा पार्ट्स

Critical installation tip for the YB60000068 / YB60000069 remanufactured pump set:
– 壳体泄油管路 on each pump must be clear and unrestricted. A blocked case drain will blow the shaft seal instantly on first startup.
– Before installing the remanufactured pumps, flush the entire hydraulic system and replace all filters. Contaminants from the failed pumps will destroy a remanufactured unit just as quickly as a new one.
– 在每个液压连接处使用新的 O 型圈和密封垫圈。重复使用密封件必然导致泄漏。.
– After installation, run the engine at low idle for 2–3 minutes with the pumps in neutral, then slowly cycle each function (boom, arm, bucket, swing, travel) to purge air from the system.
– 检查泵与发动机飞轮壳的对中情况——不对中会导致轴承过早失效和轴封泄漏。.
