   SPARKLING MACHINERY NEW EC210B EC240B EC290B 8230-36840 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC210b, EC240b, and EC290b excavators—widely used in heavy construction, mining, and large-scale infrastructure projects. As a core protective component for the excavator’s hydraulic system, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust or debris from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during high-intensity, prolonged operations.

   Engineered to match VOLVO’s original equipment performance standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous machine vibration. It resists oil aging and wear, providing long-lasting protection for the excavator’s hydraulic system. Backed by strict performance verification, it guarantees uninterrupted sealing support for EC210b/EC240b/EC290b excavators.

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.
