SPARKLING Swing Reducer Assembly – Durable & Precise Excavator Part

The JCB Swing Gearbox Assembly (suitable for JS70, PC60‑7, and PC70‑7/PC60‑7 excavators) is a precision-engineered swing reducer designed to deliver smooth and reliable rotational performance. Built to OEM standards (e.g., part no. LNM0639 / 201-26‑00130), this gearbox features hardened steel gears and robust bearings—ensuring durable operation under heavy load. It’s designed for easy drop-in replacement and reduces maintenance downtime. Ideal for construction, demolition, and excavation applications.

   SPARKLING MACHINERY NEW 312D2 313D2 320E 324E 320-3063 Pressure Sensor is a dedicated precision monitoring component exclusively designed for 312D2, 313D2, 320E, and 324E excavators. As a core part of the excavators’ hydraulic and engine systems, it real-time detects critical pressure data—such as hydraulic cylinder pressure and engine lubricating oil pressure—and transmits accurate signals to the machine’s control unit and operator panel. This function is critical for preventing overpressure or underpressure failures during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance, directly ensuring stable hydraulic power output, protecting key components (e.g., hydraulic pumps, valves, and engine bearings) from pressure-related damage, and avoiding unplanned downtime caused by pressure anomalies.

   Engineered to match original equipment performance standards, it maintains high detection accuracy even under harsh working conditions, including high oil pressure (up to 45 MPa), continuous excavator vibration, and exposure to hydraulic oil or construction site dust. It resists signal interference and corrosion, avoiding data errors that could lead to misjudgments of the excavator’s operating status. Backed by strict performance verification, it guarantees reliable pressure monitoring to support uninterrupted operation of 312D2/313D2/320E/324E excavators.

The Rexroth Relief Valve 04950403 (part no. R901102333) is a precision-engineered screw-in cartridge valve designed for hydraulic systems in excavators and industrial machinery. This robust, direct-acting spool-type valve offers pressure reducing and relieving capabilities, withstanding up to 350 bar of maximum operating pressure and supporting flow rates around 30 L/min. Constructed with quality materials and standard CAAN cavity compatibility, it ensures responsive, leak-free hydraulic control under demanding conditions.

   SPARKLING MACHINERY NEW D60P D65E D65EX D65P 14X-12-11411 Shaft is a dedicated structural and transmission component exclusively designed for D60P, D65E, D65EX, and D65P bulldozers. As a core part of the bulldozers’ undercarriage or working mechanism, it enables smooth power transmission and stable component linkage—supporting critical tasks like land leveling, soil pushing, and construction site grading. This function is essential for maintaining the bulldozers’ operational stability and load-bearing capacity, directly ensuring consistent performance during prolonged high-intensity work and reducing the risk of mechanical jams or uneven movement caused by faulty transmission.

   Engineered to match original equipment performance standards, it maintains strong torsional strength and wear resistance even under harsh working conditions, including continuous load stress, vibration, and exposure to dust or muddy debris. It resists deformation and connection loosening, avoiding mechanical failures that could lead to unplanned downtime or costly component damage. Backed by strict performance verification, it guarantees long-term reliability to support uninterrupted operation of D60P/D65E/D65EX/D65P bulldozers.
