Гидронасос Komatsu 708-1S-00130 для мини-экскаватора Komatsu PC27R-8

PC27R‑8 Hydraulic Pump for Komatsu Excavator spare parts 708‑1S‑00130 Axial Piston pump OEM

Product Brief

This OEM‑spec axial piston hydraulic pump with part number 708‑1S‑00130 serves as the core power source tailored for Komatsu PC27R‑8 mini excavator. It converts engine torque into adjustable high‑pressure hydraulic flow to support compact‑scale construction tasks, including small‑range excavation, trench digging, material handling and site cleanup. Widely used in garden renovation, municipal narrow‑space operation and indoor demolition projects, this OEM replacement pump is heavily procured by overseas repair workshops, equipment leasing dealers and cross‑border spare‑part merchants for direct pump replacement and full hydraulic system refurbishment of small‑size Komatsu machine fleets.

Working under frequent start‑stop operations, hydraulic oil impurity pollution and repeated pressure fluctuation on complex job sites, the original pump will gradually produce cylinder block scuffing, piston shoe wear, valve plate corrosion and increased internal leakage. Typical failure manifestations include weak digging output, slow boom and arm response, insufficient traveling power, continuous hydraulic oil overheating, obvious pump vibration and knocking noise under working load. Once the main pump fails unexpectedly, the whole mini excavator stops working, bringing extra repair costs and project delay losses for equipment operators.

Our OEM replacement pump strictly follows original drawing standards for mounting hole layout, input shaft spline specification, oil port position and regulator pressure preset parameters. No cutting, drilling or extra adapter modification is required during field installation, which greatly shortens equipment downtime. Compared with high‑priced genuine units with long delivery cycles, this hydraulic pump delivers stable field performance and meets bulk‑order procurement demands for global suppliers focusing on Komatsu mini excavator spare parts.

Product Highlights

1. High‑precision dimensional matching for quick on‑site maintenance
All mounting dimensions, spline parameters and oil port positions keep highly consistent with original OEM products. Service technicians can finish pump replacement directly without secondary field machining, improving repair efficiency for mini‑machine overhaul and second‑hand equipment refurbishment projects.

2. Reinforced friction‑pair craft adapting compact‑machine working conditions
Numerous low‑cost substitute pumps suffer rapid performance attenuation when matched with aged hydraulic systems mixed with tiny impurity particles. Our core internal friction components adopt optimized heat‑treatment plus multi‑process fine‑lapping technology, improving anti‑wear and anti‑pressure‑shock performance, lowering pump replacement frequency for PC27R‑8 machines operating in narrow municipal sites and landscaping construction scenarios.

3. Complete bench performance inspection before shipment
Each finished hydraulic pump carries out pressure endurance test, flow calibration and sealing leakage inspection on dedicated hydraulic test bench before packing. Potential defective products are screened in‑house, reducing re‑work risks for repair teams and avoiding sudden construction‑site shutdown caused by pump breakdown.

4. Cost‑effective OEM alternative for small‑excavator fleet management
Genuine OEM hydraulic pumps for Komatsu PC27R‑8 mini excavators come with high purchase expense and unstable stock availability. Our factory‑supplied OEM‑replacement pump balances reliable operating stability and competitive cost, helping machinery owners and service shops control overall overhaul expenditure for mini‑excavator fleets.

5. Flexible logistics solutions for bulk‑purchase customers
In‑stock items support prompt shipment upon payment confirmation. Air freight is available for urgent breakdown repair orders. Sea consolidation and full‑container transport options help global bulk importers cut comprehensive logistics expenditure.

Factory Production Strength

Our production base is engaged in R&D and mass manufacturing of OEM‑replacement hydraulic spare parts for Japanese‑brand mini and small excavators, covering main hydraulic pumps, travel gearboxes and swing motors. We possess complete production workflows: alloy‑steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench validation. Simulated short‑cycle frequent‑start working tests are implemented to verify component durability matching real‑world landscaping and municipal construction conditions. Our spare parts are exported to multiple overseas regions and maintain long‑term stable partnerships with global construction‑machinery spare‑part wholesalers.

Frequently Asked Customer Questions

Q1: Can this 708‑1S‑00130 hydraulic pump fit other Komatsu mini excavator models?
A1: Cross‑model installation is not advised. Different pump assemblies differ in shaft spline, regulator parameters and pressure calibration values. 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 abrasion: insufficient digging force, slow compound movements, hydraulic oil overheating, internal leakage and abnormal pump vibration or knocking noise.

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

Q4: What export‑grade packaging is adopted for long‑distance overseas transit?
A4: Anti‑rust grease is evenly coated on all metal working surfaces. The whole pump is wrapped with waterproof shock‑absorbing PE film, then secured inside reinforced export plywood case, protecting components against collision deformation and rust formation during long‑haul ocean transportation.
