JS235 Slewing Drive by SPARKLING – Reliable Excavator Part

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 A25D EC140C EC240C EW40D 960254 O-Ring is a dedicated sealing component exclusively engineered for VOLVO A25D articulated dump trucks, EC140C/EC240C excavators, and EW40D wheeled excavators—key equipment in construction, mining, and municipal infrastructure projects. As a critical part of the machinery’s hydraulic, fuel, and coolant systems, it creates tight, leakproof seals between mating components (e.g., hydraulic valve connections, fuel line joints, and coolant hoses). This function is essential for maintaining system pressure stability, preventing fluid leakage (hydraulic oil, fuel, coolant), and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like heavy hauling, digging, or road maintenance.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 32 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous machinery vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for VOLVO A25D/EC140C/EC240C/EW40D systems. Backed by strict performance verification, it guarantees consistent sealing support for these VOLVO models.

   SPARKLING MACHINERY NEW A35E A35G A40G A45G EC330B EC330C EC340D 11423761 Oil Level Sensor is a critical monitoring component for Volvo A35E, A35G, A40G, A45G, EC330B, EC330C, and EC340D excavators (widely used in construction, mining, and infrastructure projects). As the "oil level guardian", it real-time detects the volume of engine oil or hydraulic oil—alerting operators to low oil levels during tasks like digging, lifting, and hauling, while preventing equipment damage from oil shortage and ensuring stable lubrication or hydraulic system operation.
   Meeting Volvo OEM standards (part no. 11423761), it endures -30°C to 100°C temperatures, resists oil corrosion and vibration, and guarantees accurate signal transmission. Strict testing ensures seamless compatibility with the seven Volvo models and long-term oil system monitoring reliability.
