SK200‑5 Hydraulic Pump for Kobelco Excavator spare parts YY10V00009F4 Axial Piston pump OEM

Product Brief

This OEM‑grade axial piston main pump, part number YY10V00009F4, serves as the core hydraulic power source for Kobelco SK200‑5 medium‑size excavator. It converts mechanical power from the engine into high‑pressure hydraulic flow, supporting composite movements including digging, lifting, slewing and travelling. Well‑suited for earth‑moving projects, urban site development and aggregate‑loading work sites, this OEM replacement pump is widely sourced by overseas service centers, equipment rental enterprises and cross‑border spare‑part distributors for hydraulic system overhaul and direct worn‑pump replacement of Kobelco SK200‑5 machine fleets.

Under long‑time cyclic pressure load, hydraulic oil contamination and frequent working condition switching, the original pump will gradually suffer internal valve‑plate scuffing, piston shoe wear, swash‑plate abrasion and increased internal leakage. Typical failure symptoms include insufficient digging force, slow combined actions, obvious power drop under heavy load, high hydraulic oil temperature, abnormal noise inside pump housing and machine drifting during operation. Once severe internal damage occurs, the whole hydraulic system will lose output capacity, leading to machine shutdown, costly field maintenance and project schedule delays for equipment operators.

Our OEM replacement pump strictly implements original drawing standards for port layout, valve‑plate profile, piston assembly parameters and mounting flange dimension. No re‑drilling or gasket modification is needed during on‑site installation. Service crews can complete pump swap without extra alteration, effectively cutting equipment downtime. Compared with high‑priced genuine units with long procurement lead‑times, this hydraulic pump delivers steady working performance and meets bulk‑order purchasing requirements for global suppliers focusing on Kobelco SK series excavator hydraulic spare parts.

Product Highlights

1. Flawless mounting compatibility for on‑site rapid hydraulic overhaul
All flange sizes, oil port positions and drive‑shaft spline parameters conform to OEM specifications. Maintenance technicians can finish pump replacement directly without secondary machining, raising repair throughput for repair shops and used‑machine refurbishment projects.

2. Reinforced internal friction pairs adapting variable‑load construction scenarios
Many low‑cost substitute pumps suffer rapid efficiency loss when operating with polluted hydraulic oil. Our core internal friction components adopt optimized material formula plus high‑precision surface grinding process, enhancing anti‑wear and anti‑cavitation performance, extending service life for SK200‑5 units working under frequent load‑changing conditions.

3. Full‑set performance testing before product shipment
Each finished hydraulic pump undergoes pressure‑holding test, flow‑rate detection and noise inspection on professional hydraulic test bench before packing. Potential defective products are eliminated in‑factory, lowering re‑work risk for service teams and avoiding unexpected hydraulic‑system failure on construction sites.

4. Reliable OEM‑level alternative for medium‑size excavator fleet cost control
Genuine OEM main pumps for Kobelco SK200‑5 come with high purchase cost and unstable stock supply. Our factory‑supplied replacement pump balances dependable hydraulic output and competitive cost, helping equipment owners and service workshops control overall maintenance expenditure for excavator fleets.

5. Multiple logistics options for bulk‑purchase clients
In‑stock goods support prompt shipment upon payment confirmation. Air freight service is available for urgent breakdown repair orders. Sea consolidation and full‑container transport schemes help overseas bulk importers reduce comprehensive logistics expenditure.

Factory Production Strength

Our production base devotes to R&D and mass manufacturing of OEM‑replacement hydraulic pumps for Japanese‑brand medium excavators, covering main axial piston pumps, pilot pumps and related hydraulic accessories. We possess complete production workflows: alloy‑steel precision processing, surface heat‑treatment, component assembling and finished‑product hydraulic bench validation. Simulated variable‑pressure cyclic tests are carried out to verify component durability matching real‑world earth‑moving and municipal‑construction operating conditions. Our spare parts are exported to multiple overseas regions and keep long‑run stable cooperative relationships 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 port arrangement. Please double‑confirm machine model and original part number before submitting orders.

Q2: What hydraulic malfunctions can this main pump resolve?
A2: It fixes failures caused by internal‑component wear: insufficient digging power, sluggish compound movements, high hydraulic oil temperature, internal leakage, abnormal pump noise and weak load‑bearing capacity.

Q3: Is tiered volume discount offered for large‑quantity orders?
A3: Yes, preferential pricing is subject to purchasing quantity. Full‑container sea freight arrangement can be supported to cut total logistics cost.

Q4: What export‑grade packaging is adopted for long‑distance overseas transit?
A4: Anti‑rust oil is sprayed on all precision mating surfaces. The whole pump is wrapped with waterproof anti‑rust film and shock‑absorbing foam, then secured inside reinforced plywood case, protecting internal precision parts against collision and rust during long‑haul ocean transportation.
