   SPARKLING MACHINERY NEW PC200-5 PC220-5 6620-11-3011/BM68974 Injector is a core fuel supply component for Komatsu PC200-5 and PC220-5 excavators (widely used in construction, mining, and earthmoving projects). As the "fuel precision distributor", it atomizes and delivers fuel to the engine cylinders with optimal pressure and timing—ensuring efficient combustion during tasks like digging, lifting, and rock breaking, while preventing incomplete fuel burn that causes engine power loss or increased emissions.
   Meeting Komatsu OEM standards (part nos. 6620-11-3011/BM68974), it endures -30°C to 120°C temperatures, resists fuel corrosion and vibration, and guarantees stable fuel injection. Strict testing ensures seamless compatibility with the two Komatsu models and long-term engine performance reliability.

The PM05P00013S001 Radiator, offered by SPARKLING MACHINERY, is a high-quality replacement cooling system component specifically designed for New Holland E27B/E27BSR, CASE CX27B, and Kobelco SK27SR-3 mini excavators.

Built using premium aluminum and designed for efficient heat dissipation, this radiator ensures optimal engine performance and longevity even in demanding work environments. It matches OEM specifications and comes ready to install—making it an ideal choice for maintenance, replacement, or refurbishment.

The CATERPILLAR Spider Assembly Fan 6-Blade (part numbers CA5117558, 511-7558, 5117558) is a high-quality cooling fan designed specifically for the CAT Material Handler MH3250. This robust 6-blade fan spider assembly plays a vital role in maintaining optimal engine temperatures by efficiently driving airflow through the radiator and cooling system.

Crafted from durable materials to withstand demanding industrial environments, the fan spider ensures reliable performance and long service life. Its precision design promotes effective heat dissipation, helping to prevent engine overheating during heavy-duty material handling operations.

Whether you are replacing a worn-out fan or upgrading your cooling system components, this OEM-quality spider fan assembly fits perfectly and supports your machine’s consistent performance on the job site.
