SPARKLING JRC0007 Reducer

Heavy-Duty Swing Gearbox Reducer for Hitachi JS Excavators
Engineered for JS200, JS210, JS220, JS220LR, and JS235 excavators, the Swing Gearbox Reducer (JRC0007) is the precision heart of your machine’s rotation system. This OEM-compatible reducer delivers unmatched torque transmission and smooth 360° slewing motion under extreme loads. Forged with hardened helical gears and triple-sealed bearings, it resists wear, minimizes backlash, and withstands relentless job site vibrations. SPARKLING MACHINERY’s JRC0007 undergoes rigorous cycle testing to ensure perfect meshing alignment and extended service life – because precise rotation isn’t a luxury, it’s the core of your excavator’s productivity.

   SPARKLING MACHINERY NEW L90E L70E L60E A30D L150E 22996281 Pressure Switch is a critical hydraulic safety monitoring component for Volvo L90E, L70E, L60E, A30D, and L150E excavators (widely used in construction, mining, and material handling projects). As the "hydraulic pressure alert trigger", it real-time monitors pressure fluctuations in hydraulic circuits—automatically sending signals to the excavator’s control unit when pressure exceeds or drops below safe thresholds. This ensures timely protection during tasks like lifting heavy loads or digging, preventing overpressure damage to pumps/valves and underpressure-related operational failures.
   Meeting Volvo OEM standards (part no. 22996281), it endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees reliable pressure sensing. Strict testing ensures seamless compatibility with the five Volvo models and long-term hydraulic system safety.

   SPARKLING MACHINERY NEW EC330B EC330C EC340D EC350D EC350E VOE14880680/14403374 Hose is a dedicated flexible fluid transmission component for VOLVO EC330B, EC330C, EC340D, EC350D, and EC350E heavy crawler excavators (widely used in large-scale mining, construction, and infrastructure projects). As a core part of the excavator’s hydraulic system, it transfers high-pressure hydraulic oil between key components (e.g., pumps, cylinders, control valves) to ensure uninterrupted power supply for tasks like rock breaking, bulk ore loading, and deep digging.
   Meeting VOLVO OEM standards (part nos. VOE14880680/14403374), it endures 32 MPa hydraulic pressure, -35°C to 100°C temperatures, and repeated bending. Strict testing guarantees seamless compatibility with the five VOLVO models and long-term leak-free, reliable fluid transmission.

   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.
