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.

The CA2341981 Air Cleaner GP is a genuine-quality replacement component designed to deliver optimal engine protection for Caterpillar backhoe loaders.

   SPARKLING MACHINERY NEW E320GC E323D E326GC E330GC E336GC E349GC 485-5747 Solenoid Valve is a core hydraulic control component for Caterpillar E320GC, E323D, E326GC, E330GC, E336GC, and E349GC excavators (widely used in construction, mining, and large-scale infrastructure projects). As the "hydraulic flow switch", it regulates the on/off and direction of hydraulic oil flow—controlling key functions like boom lifting, bucket digging, and arm movement during high-intensity tasks, while ensuring responsive and precise operation to avoid hydraulic system misalignment.
   Meeting Caterpillar OEM standards (part no. 485-5747), it endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees leak-free and stable electromagnetic control. Strict testing ensures seamless compatibility with the six Caterpillar models and long-term hydraulic system reliability.

   SPARKLING MACHINERY NEW EC180B EC135B EC160B 8038-00010 Seal Kit is a dedicated sealing solution exclusively designed for VOLVO EC180B, EC135B, and EC160B excavators—widely used in construction, mining, and infrastructure maintenance. As a comprehensive set of sealing components, it covers critical parts of the excavator’s hydraulic system (e.g., cylinder rods, valve connections, and pump interfaces), creating leakproof barriers to prevent hydraulic oil leakage. This function is vital for maintaining stable hydraulic pressure, ensuring smooth operation of core mechanisms (like boom lifting and arm digging), and avoiding contamination of internal components by dust or debris. It directly reduces the risk of hydraulic system failures, unplanned downtime, and costly repairs caused by oil leaks during high-intensity work.

   Engineered to match VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions—including high hydraulic pressure (up to 35 MPa), temperature fluctuations (-20°C to 100°C), and continuous machine vibration. It resists oil aging and material wear, ensuring long-term protection for the excavator’s hydraulic system. Backed by strict performance tests, it guarantees consistent sealing to support uninterrupted operation of EC180B/EC135B/EC160B excavators.
