Product Description

Komatsu PC40MR-1 mini excavator, part number 708-3S-00461. The mounting flange, spline shaft, and high/low pressure oil port dimensions are perfectly matched, allowing for direct replacement in situ without modification. The cylinder block, plunger, and distributor plate are made of high-wear-resistant alloy material, ensuring stable volumetric efficiency under high pressure. This effectively solves common excavator malfunctions such as weak movement, slow lifting, stalling, high temperature, and hydraulic internal leakage. It offers a high-performance, cost-effective assembly for mini excavator repair and replacement.

1. Integrated cast steel pump housing, pressure and impact resistant, less prone to cracking and leakage during prolonged heavy-duty operation;

2. Equipped with a power regulating control valve, precise load sensing, automatically matching engine output power, reducing fuel consumption and minimizing stalling;

3. Core hydraulic friction pairs are high-precision ground, wear-resistant and scratch-resistant, effectively inhibiting internal leakage and mitigating overall machine heat dissipation;

4. All units undergo full-load high-pressure bench testing before leaving the factory, meeting sealing, flow, and pressure standards, suitable for landscaping renovations, indoor demolition, and construction on narrow municipal roads.
