SPARKLING Komatsu Excavator Hydraulic Pump – Durable & Precise

SPARKLING MACHINERY’s 708-3S-00513 and 708-3S-00422 hydraulic pumps are high-quality replacements for Komatsu PC35MR-2 and PC40MR mini excavators. Built for durability and smooth power delivery, they ensure OEM fit, long service life, and reliable performance in tough conditions—backed by fast global shipping and solid support.

The 708-3S-00513 and 708-3S-00422 hydraulic pump assemblies are precision-engineered spare parts for Komatsu PC35MR-2 and PC40MR mini excavators. As the heart of the excavator's hydraulic system, these pumps deliver high-efficiency power transfer for critical operations including boom movement, arm control, bucket operation, and swing functions.

Built to OEM quality standards, this hydraulic pump features a compact yet powerful design, ensuring stable output pressure, energy efficiency, and reduced system noise. Whether for repair or replacement, it provides excellent compatibility and long-term reliability for light and medium-duty excavation work.

Each pump is fully tested, sealed, and packaged for international delivery by SPARKLING MACHINERY—a trusted supplier of excavator hydraulic parts for global customers.

   SPARKLING MACHINERY NEW 172460-73410 Gear Pump is a core hydraulic power component for Komatsu excavators (heavy-duty construction/mining use). It converts engine mechanical energy into hydraulic pressure to drive actuators (e.g., arms, buckets), ensuring smooth operational movement. 
   Meeting Komatsu OEM standards (172460-73410), it resists -30°C to 100°C temps, pressure fluctuations, and wear, ensuring seamless compatibility and long-term reliable hydraulic output.

The Main Pump Slider (Part No. 708-2L-44120) is a precision hydraulic component designed for Komatsu excavators PC210-7K, PC210-8K, and PW200-7.

This slider plays a critical role in the operation of the hydraulic main pump, ensuring smooth movement, accurate flow control, and stable pressure performance. Manufactured from high-quality materials and finished with precise machining, it is built to meet OEM dimensional and functional standards.

With a lightweight design of 0.25 kg, the main pump slider helps reduce internal friction and wear, contributing to improved pump efficiency and extended service life. It is an ideal aftermarket replacement for hydraulic system maintenance, repair, and overhaul.

   SPARKLING MACHINERY NEW R80-7 R80-7A 11N1-42120 Oil Cooler is a dedicated thermal management component exclusively designed for R80-7 and R80-7A excavators. As a core part of these excavators’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during tasks like small-scale construction, agricultural tillage, and urban infrastructure maintenance. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (such as hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable power output and extending the service life of R80-7/R80-7A excavators.

   Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous excavator vibration. It resists oil leakage and internal blockages, avoiding system failures that could lead to unplanned downtime or costly component repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of R80-7 and R80-7A excavators.
