SPARKLING Mobile Hydraulic Power Unit Coupling

The CATERPILLAR 310-9497 Coupling GP – Flexible (also known as CA3109497 or 3109497) is a critical drivetrain component designed to connect the engine to the hydraulic or mechanical power transmission systems. Specifically engineered for CAT Excavators 336E, 345D, 349DL, 568FMLL, and mobile hydraulic power units, this flexible coupling provides smooth torque transmission while compensating for misalignment and vibration between components.

Compatible with Caterpillar C9.3 and C13 engines, this coupling ensures enhanced durability and performance under heavy-duty conditions. Whether operating in construction, forestry, or mining environments, the 310-9497 flexible coupling is built to OEM specifications to deliver consistent power with minimal wear and noise.

Its robust rubber-metal composite design helps absorb shock loads, reduce system stress, and protect vital engine and pump components—making it essential for maintaining operational efficiency and preventing costly downtime.

   SPARKLING MACHINERY NEW EC140 EC140B EC210 EC210B EC240 EC240B VOE14500037 Relief Valve is a dedicated hydraulic pressure protection component for Volvo EC140, EC140B, EC210, EC210B, EC240, and EC240B crawler excavators (widely used in construction, municipal engineering, and medium-scale mining). As the "safety core" of the hydraulic system, it automatically releases excess pressure when it exceeds the set threshold—preventing damage to pumps, hoses, and cylinders during high-intensity tasks like digging, lifting, and rock breaking.
   Meeting Volvo OEM standards (part no. VOE14500037), it maintains a precise pressure range of 26-30 MPa, endures -30°C to 95°C temperatures, resists oil corrosion and vibration, and ensures instant relief response. Strict testing guarantees seamless compatibility with the six Volvo models and long-term hydraulic system safety.

   SPARKLING MACHINERY NEW ZX200 ZX225USR ZX270-HHE ZX330 0004307 Wiring Harness is a dedicated electrical connection component for Hitachi ZX200, ZX225USR, ZX270-HHE, and ZX330 crawler excavators (heavy-duty equipment for construction, mining, and infrastructure projects). As the "nerve system" of the excavator’s electrical system, it transmits stable electrical signals between core components (e.g., controllers, sensors, actuators) to ensure smooth operation of functions like engine start, hydraulic control, and cab instrument display during high-intensity tasks.
   Meeting Hitachi OEM standards (part no. 0004307), it endures -30°C to 85°C temperatures, resists moisture and abrasion, and maintains reliable insulation. Strict testing guarantees seamless compatibility and long-term signal transmission stability for the four Hitachi models.
