SPARKLING Caterpillar 333‑3073 Swing Reducer

The Caterpillar Swing Reducer (Part No. 333‑3073 / 3333073) is a premium swing gearbox designed to restore smooth and powerful 360° rotation in CAT excavators—compatible with 312D, 312DL, 312D2, 312E, 313D, 313D2, 314C, and 314E models. 

It features hardened steel planetary gears, sealed bearings, and robust housing to handle heavy-duty rotational loads while preventing leaks and contamination . Available as genuine OEM or high-quality aftermarket units, this swing reducer ensures a direct-fit replacement and optimized machine performance.

   SPARKLING MACHINERY NEW CX300C CX350C 84389386 Turbocharger is a dedicated, high-performance engine component exclusively engineered for CASE CX300C and CX350C crawler excavators—heavy-duty equipment widely used in large-scale construction, mining, and infrastructure development projects. As a core part of the excavator’s engine system, it enhances air intake efficiency by compressing incoming air, directly boosting engine power output, optimizing fuel combustion, and reducing energy waste. This function is critical for maintaining stable engine performance during high-intensity tasks like rock breaking, bulk material loading, and deep excavation, preventing power loss under heavy loads and ensuring consistent workflow efficiency.

   Engineered to meet CASE’s original equipment (OEM) standards and marked with the specific part number 84389386, the turbocharger withstands harsh working conditions: extreme engine temperatures (up to 820°C), high rotational speeds (up to 145,000 RPM), and continuous vibration from heavy-duty operations. It resists thermal fatigue, oil contamination, and mechanical wear, providing long-lasting reliability for the CX300C/CX350C’s engine systems. Backed by strict performance verification, it guarantees seamless compatibility and optimal engine performance for these CASE excavator models.

   SPARKLING MACHINERY NEW A25G A30F A35G A40F 14514330 Sensor is a key monitoring component for Volvo A25G, A30F, A35G, and A40F excavators (widely used in construction, mining, and heavy earthmoving). As the "equipment status detector", it real-time collects critical data—such as hydraulic pressure, engine temperature, or fuel level—transmitting accurate signals to the excavator’s control unit. This ensures operators stay informed during tasks like loading, hauling, and dumping, while preventing equipment damage from abnormal parameters and maintaining consistent operational performance.
   Meeting Volvo OEM standards (part no. 14514330), it endures -30°C to 100°C temperatures, resists dust and vibration, and guarantees stable signal output. Strict testing ensures seamless compatibility with the four Volvo models and long-term monitoring reliability.
