SPARKLING Swing Reducer Replacement – Durable Excavator Parts

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 HX330L 39K9-12100 Swing Reduction Gear is a premium China-made transmission component specifically engineered for HX330L excavators. As a critical part of the swing system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 363-811-25090 Front Brake Pad Kit is a critical safety component for Tadano excavators (widely used in construction, heavy lifting, and infrastructure projects). As the "front braking backbone", it generates friction with the front brake disc to decelerate or stop the excavator during on-site maneuvering—ensuring responsive braking for tasks like load positioning, slope navigation, and tight-space turning, while preventing front brake failure that risks equipment collisions or on-site accidents.
   Meeting Tadano OEM standards (part no. 363-811-25090), it endures -30°C to 300°C braking temperatures, resists heat fading and wear, and maintains a stable friction coefficient. Strict testing guarantees seamless compatibility with applicable Tadano models and long-term front braking system reliability.

   SPARKLING MACHINERY NEW R210-7 R220-7 R250-7 R290-7 R305-7 R335-7 11Q6-90040 Compressor Assy is a dedicated air conditioning core component for Hyundai R210-7, R220-7, R250-7, R290-7, R305-7, and R335-7 crawler excavators (widely used in construction, mining, and infrastructure projects). As the "cooling power source" of the excavator cab, it compresses refrigerant to maintain stable temperature control—ensuring a comfortable operating environment for operators during long-hour tasks in high-temperature or harsh weather.
   Meeting Hyundai OEM standards (part no. 11Q6-90040), it endures -20°C to 80°C temperatures, resists vibration and refrigerant corrosion, and maintains consistent cooling efficiency. Strict testing guarantees seamless compatibility with the six Hyundai models and long-term reliable cab air conditioning performance.
