   SPARKLING MACHINERY NEW 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.

   SPARKLING MACHINERY NEW EC160B EC180B EC290B EC240B EW170 SA1123-02341/14623863 Converter is a key power conversion component for 5 Volvo excavator models (construction/mining use). It converts electrical energy between voltage/current formats to power on-board systems (e.g., sensors, controllers), ensuring stable energy supply. 
   Meeting Volvo OEM standards (SA1123-02341/14623863), it resists -30°C to 85°C temps, voltage fluctuations, and vibration, guaranteeing seamless compatibility and long-term reliable performance.

The PH05P00021F1 Radiator from SPARKLING MACHINERY is a durable, high-performance cooling component designed to fit a range of mini and midi excavators, including New Holland E50SR/E50BSR, CASE CX50B, and Kobelco SK40SR-3.

Manufactured with precision using corrosion-resistant materials and strict quality control, this radiator ensures optimal engine cooling even under harsh job site conditions. It’s a dependable, cost-effective replacement for OEM parts, ready to install and built to last.
