SK130 SK140-8 Hydraulic Pump for Kobelco Excavator spare parts YY10V00009F4 Aftermarket

Product Brief

This aftermarket K7V63DTP variable axial piston main pump with part number YY10V00009F4 serves as the core hydraulic power assembly for Kobelco SK130 and SK140-8 medium excavators. It converts engine rotational energy into controllable high-pressure hydraulic oil flow to drive bucket excavation, boom lifting, arm movement, machine slewing and crawler travel simultaneously. Widely applied in medium earthmoving, road renovation, quarry material loading and large trench construction, this replacement pump is favored by overseas repair workshops, equipment leasing firms and cross-border spare part distributors for hydraulic system overhaul and direct replacement of worn pumps on Kobelco SK130 / SK140-8 machine fleets.

During long-term continuous operation under heavy load fluctuations, contaminated hydraulic oil and frequent compound movements, the original pump will gradually develop cylinder barrel scratching, piston shoe abrasion, valve plate wear and rising internal leakage. Typical failure manifestations include insufficient digging force, slow combined actions, power attenuation under heavy digging load, continuous rise of hydraulic oil temperature, abnormal humming or knocking noise from pump housing and delayed machine response. Once severe internal damage occurs, the whole hydraulic system will lose output capacity, leading to machine shutdown, high on-site maintenance expense and construction schedule delay for equipment owners.

Our aftermarket hydraulic pump strictly follows original drawing specifications for mounting flange dimension, drive shaft spline profile, oil port layout and regulator pressure preset value. No extra drilling, cutting or gasket modification is needed during field installation. Maintenance technicians can complete pump replacement smoothly to minimize machine downtime. Compared with high-priced genuine pumps with long procurement lead times, this hydraulic pump delivers stable working performance and supports bulk repeated purchasing for global merchants specializing in Kobelco medium excavator hydraulic spare parts.

Product Highlights

1. Complete interchangeability to accelerate medium excavator hydraulic overhaul
All flange sizes, oil port positions and drive shaft spline parameters fully match original specs. Service crews can finish pump swap without secondary machining, improving overhaul efficiency for repair centers and used medium excavator refurbishment projects.

2. Optimized friction pair design to withstand variable heavy-duty working loads
Many low-cost substitute pumps rapidly lose volumetric efficiency when working with contaminated hydraulic fluid mixed with tiny metal debris. Our core internal friction parts adopt upgraded heat treatment plus ultra-precise surface grinding craft, enhancing anti-cavitation and anti-wear performance, extending service life for SK130 / SK140-8 excavators operating in medium and large earthmoving sites.

3. Comprehensive bench performance testing before shipment
Each finished hydraulic pump undergoes pressure holding test, flow calibration and noise inspection on dedicated hydraulic test bench before packing. Defective units are filtered out inside factory, lowering rework risks for service teams and avoiding sudden hydraulic system breakdown on construction sites.

4. Cost-effective aftermarket option for medium excavator fleet maintenance
Genuine main pumps for Kobelco SK130 and SK140-8 carry high purchase cost and unstable stock availability. Our factory-direct replacement pump balances reliable hydraulic output and competitive pricing, helping machine owners and service shops cut total fleet maintenance expenditure.

5. Multiple logistics schemes for bulk purchasers
In-stock products support quick shipment after payment confirmation. Air freight service can be arranged for urgent emergency breakdown orders. Sea consolidation and full-container transport help overseas bulk buyers reduce overall logistics costs.

Factory Production Strength

Our manufacturing plant specializes in R&D and mass production of aftermarket hydraulic spare parts for Japanese medium excavators, including axial piston main pumps, pilot pumps and matched hydraulic accessories. We have full production workflows: alloy steel precision machining, surface heat treatment, component assembly and finished-product hydraulic bench validation. Simulated variable-pressure cyclic durability tests are carried out to verify component durability under real-world road construction and quarry operating environments. Our spare parts are exported to multiple overseas markets and maintain long-term stable cooperation with global construction machinery spare part wholesalers.

Frequently Asked Customer Questions

Q1: Can this YY10V00009F4 hydraulic pump fit other Kobelco excavator models?
A1: Cross-model installation is not recommended. Different main pumps differ in shaft spline, displacement and oil port arrangement. Please double-check machine model and original part number before placing orders.

Q2: What hydraulic faults can this main pump solve?
A2: It resolves malfunctions caused by internal component abrasion: insufficient digging power, slow compound movements, high hydraulic oil temperature, internal leakage, abnormal pump noise and weak heavy-load capacity.

Q3: Is tiered volume discount available for large quantity orders?
A3: Yes, preferential pricing depends on purchasing quantity. Full-container sea freight arrangement can be supported to reduce total logistics expense.

Q4: What export-grade packaging is used for long-distance overseas transit?
A4: Anti-rust oil is applied on all precision mating surfaces. The pump is wrapped with waterproof anti-rust film and shock-absorbing foam, then fixed inside reinforced plywood case, protecting precision internal components against collision and rust during long ocean shipping.
