Pompe hydraulique Nachi PVD-3B-60L5P-9G YT10V00023F1 pour mini-pelle Kobelco SK75-8

SK75-8 Hydraulic Pump for Kobelco Excavator spare parts YT10V00023F1 K3SP36B Aftermarket

Product Brief

This aftermarket K3SP36B variable axial piston main pump, part code YT10V00023F1, serves as the core hydraulic power assembly built for Kobelco SK75-8 7.5-ton midi excavator. It converts engine rotational power into adjustable high-pressure hydraulic flow to synchronously drive bucket excavation, boom lifting, arm movement, machine slewing and track travel. Widely deployed in urban pipeline trenching, landscaping earthmoving, small foundation works and demolition projects, this replacement pump is popular among overseas service depots, midi excavator rental operators and cross-border spare part wholesalers for hydraulic system overhaul and direct worn pump replacement of Kobelco SK75-8 machine fleets.

Under continuous cyclic pressure load, hydraulic oil contamination and frequent action switching on compact job sites, the original pump will gradually experience cylinder block scuffing, piston shoe wear, swash plate abrasion and elevated internal leakage. Typical field symptoms include insufficient digging strength, sluggish combined movements, power drop under heavy digging load, persistent rise in hydraulic oil temperature, abnormal buzzing or knocking noise from pump housing and unsmooth machine operation response. Once severe internal damage takes place, the whole hydraulic system loses power output, causing machine downtime, high on-site repair bills and construction schedule delays for equipment owners.

Our aftermarket hydraulic pump strictly copies original component standards for mounting flange dimension, drive shaft spline, oil port layout and load sensing regulator calibration. No re-drilling, cutting or gasket modification is required during field installation. Service technicians can complete pump swap seamlessly, greatly cutting machine idle time. Compared with expensive genuine pumps with long procurement lead times, this hydraulic pump delivers stable hydraulic performance and meets bulk repeated purchasing requirements for global merchants specializing in Kobelco midi excavator hydraulic spare parts.

Product Highlights

1. Full OEM dimension interchangeability for fast on-site hydraulic repair
All flange sizes, oil port positions and drive shaft spline parameters match original specifications exactly. Maintenance crews can finish pump replacement without secondary machining work, boosting overhaul efficiency for repair centers and pre-owned midi excavator refurbishment projects.

2. Reinforced friction pair design to handle frequent fluctuating loads
Many low-cost substitute pumps suffer fast volumetric efficiency loss when working with contaminated hydraulic fluid carrying fine metal debris. Our core internal friction components adopt upgraded heat treatment plus ultra-precise surface grinding craft, improving anti-cavitation and anti-wear capability, extending service life for SK75-8 excavators working in narrow urban construction sites
.
3. Multi-stage bench performance inspection before shipment
Each finished hydraulic pump undergoes pressure holding test, flow rate calibration and noise assessment on dedicated hydraulic test bench before packing. Defective units are screened out inside factory, lowering rework risks for service teams and avoiding unexpected hydraulic system breakdown at construction sites.

4. Practical aftermarket selection for midi excavator fleet cost control
Genuine main pumps for Kobelco SK75-8 come with high purchase price and unstable stock availability. Our factory-direct replacement pump balances reliable hydraulic output and competitive pricing, helping machine owners and service workshops optimize overall fleet maintenance spending.

5. Flexible logistics options for bulk buyers
In-stock goods support quick shipment once payment is confirmed. Air freight service is available for urgent emergency breakdown orders. Sea consolidation and full-container transport plans help overseas bulk purchasers reduce comprehensive logistics costs.

Factory Production Strength

Our manufacturing plant focuses on R&D and mass production of aftermarket hydraulic spare parts for Japanese midi excavators, covering axial piston main pumps, integrated pilot pumps and supporting hydraulic accessories. We maintain complete production workflows: alloy steel precision machining, surface heat treatment, component assembly and finished-product hydraulic bench validation. Simulated alternating pressure cyclic durability tests are performed to verify part durability under real-world municipal and small earthmoving working environments. Our spare parts are exported to multiple overseas markets and maintain long-term stable cooperation partnerships with global construction machinery spare part wholesalers.

Frequently Asked Customer Questions

Q1: Can this YT10V00023F1 K3SP36B 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 resolve?
A2: It addresses 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 is determined by purchasing quantity. Full-container sea freight arrangement can be supported to cut 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 from collision and rust during long ocean shipping.
