SPARKLING CAT 312E Swing Motor – Durable & High-Performance Excavator Part

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 VOE14561971 VOE14561970 Gear Pump is a critical hydraulic power component designed for compatible construction machinery, such as excavators and loaders. As the "hydraulic power source" of the machinery’s hydraulic system, it converts mechanical energy from the engine into hydraulic energy by generating stable oil pressure and flow. This hydraulic energy drives key working mechanisms—including boom lifting, bucket digging, and arm rotation—ensuring smooth, powerful operation during heavy-duty tasks like construction earthmoving, mining loading, and infrastructure construction.

   Engineered to match original equipment performance standards, it maintains reliable hydraulic output even under harsh working conditions, such as high-pressure loads, continuous vibration, and temperature fluctuations. It prevents oil leakage and pressure loss, avoids inefficient hydraulic operation caused by flow instability, and safeguards the integrity of the entire hydraulic system. Backed by strict performance verification, it guarantees long-term stable power supply to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW VOE14531705 Wire Harness is a dedicated electrical connection component for compatible VOLVO excavator models (widely used in construction, mining, and municipal infrastructure projects). As the "electrical nerve network" of the excavator, it transmits stable signals between core components—such as controllers, sensors, and actuators—to ensure smooth operation of critical functions like engine start, hydraulic control, and cab instrument display during high-intensity tasks.
   Meeting VOLVO OEM standards (part no. VOE114531705), it endures -30°C to 85°C temperatures, resists moisture, dust, and abrasion, and maintains reliable insulation. Strict testing guarantees seamless compatibility with applicable VOLVO models and long-term stable signal transmission.

   SPARKLING MACHINERY NEW CX350C CX290B CX300C CX800B CX460 KHH10850 Reserve Tank is a dedicated fluid storage component for CASE CX350C, CX290B, CX300C, CX800B, and CX460 crawler excavators (heavy-duty equipment for mining, construction, and infrastructure projects). As a key part of the excavator’s cooling or hydraulic system, it stores and supplements coolant or hydraulic oil, maintaining stable fluid levels to prevent overheating or pressure loss during high-intensity tasks like rock breaking and bulk material loading.
   Meeting CASE OEM standards (part no. KHH10850), it endures -30°C to 110°C temperatures, resists fluid corrosion and impact, and ensures leak-free storage. Strict testing guarantees seamless compatibility and long-term reliable performance for the five Case models.
