미니 굴착기 Hitachi ZX85USB-6용 유압 펌프 FYD00002228

ZX85USB-6 Hydraulic Pump for Excavator spare parts FYD00002228 OEM

Product Brief

This OEM specification variable axial piston hydraulic pump, part number FYD00002228, serves as the core hydraulic power source designed for Hitachi ZX85USB-6 compact excavator. It converts engine rotation power into adjustable high-pressure hydraulic flow to control bucket digging, boom lifting, arm movement, upper body slewing and crawler travel. This hydraulic pump is widely applied in narrow trench excavation, landscaping work, small demolition and municipal pipeline maintenance. It is a preferred replacement part for field repair workshops, compact excavator rental operators and international spare parts merchants to carry out hydraulic system overhaul and replace worn pumps on ZX85USB-6 machines.

Long hours of continuous operation, frequent start-stop cycles and unclean hydraulic oil will gradually lead to cylinder barrel scratches, piston shoe wear and valve plate abrasion, which increases internal leakage. Obvious malfunction symptoms include weak digging force, slow combined movements, power drop under heavy load, continuous rise of hydraulic oil temperature, abnormal pump humming and delayed machine response. Once the internal components suffer severe damage, the whole hydraulic system will lose power output, causing machine shutdown, high on-site repair fees and suspended construction projects.

Our hydraulic pump is manufactured strictly according to OEM technical standards. Mounting flange size, drive shaft spline, oil port layout and regulator pressure parameters are fully consistent with original specs. No cutting, drilling or gasket modification is needed during installation. Service technicians can complete pump replacement quickly and cut down machine downtime. Compared with genuine pumps with high price and long delivery lead time, this OEM replacement pump maintains stable hydraulic performance and supports bulk purchasing for suppliers focusing on Hitachi compact excavator hydraulic spare parts.

Product Highlights

1. OEM 1:1 dimensional matching for seamless installation
All mounting dimensions, spline specifications and oil port positions fully match original components. No secondary machining required during replacement, helping mechanics finish hydraulic overhaul efficiently and reduce equipment idle time.

2. Reinforced friction pair for frequent intermittent working conditions
Many low-cost replacement pumps suffer rapid volumetric efficiency loss when hydraulic oil contains tiny metal contaminants. Our core internal friction components adopt optimized heat treatment and ultra-precise grinding technology, improving anti-wear and anti-cavitation performance to extend service life for ZX85USB-6 excavators working in tight construction sites.

3. Full hydraulic bench inspection before delivery
Each finished pump will pass pressure holding test, flow detection and noise check before packaging. Defective items are eliminated in factory inspection, lowering rework risks and preventing unexpected hydraulic failure at job sites.

4. Reliable OEM alternative for compact excavator fleet maintenance
Genuine hydraulic pumps for Hitachi ZX85USB-6 have high procurement cost and unstable stock supply. Our factory direct supply balances dependable performance and competitive price, helping equipment owners and repair shops reduce overall maintenance expenses.

5. Flexible shipping solutions for different order sizes
In-stock goods support fast shipment after payment confirmation. Air freight is available for urgent breakdown orders. Sea consolidation and full container shipping can be arranged for bulk buyers to cut logistics expenditure.

Factory Production Strength

Our factory specializes in developing and producing OEM-grade hydraulic spare parts for Japanese compact excavators, including axial piston main pumps, pilot pumps and matched hydraulic accessories. We have a complete production chain covering alloy steel forging, precision machining, heat treatment, assembly and finished product hydraulic bench testing. Cyclic load durability tests are carried out to verify component stability under real landscaping and municipal construction environments. Our hydraulic spare parts are exported to multiple overseas regions and we keep long-term cooperative relationships with global construction machinery spare part wholesalers.

Frequently Asked Customer Questions

Q1: Can this FYD00002228 hydraulic pump fit other Hitachi excavator models?
A1: Cross-model installation is not recommended. Different main pumps differ in displacement, shaft spline and oil port arrangement. Please verify machine model and original part number before placing orders.

Q2: What hydraulic issues can this pump resolve?
A2: It fixes failures caused by internal component wear: insufficient digging power, slow compound actions, high hydraulic oil temperature, internal leakage, abnormal pump noise and weak heavy-load performance.

Q3: Is volume discount available for bulk orders?
A3: Yes, preferential pricing is determined by purchase quantity. Full container sea freight service can be arranged to save logistics cost.

Q4: What export packaging is adopted for long-distance ocean transit?
A4: Anti-rust oil is coated on all precision mating surfaces. The pump is wrapped by waterproof anti-rust film and shockproof foam, then fixed inside reinforced plywood case to protect precision parts from collision and rust during overseas shipment.
