SPARKLING CA3109497 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 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.

The Kawasaki K3V63DTP Hydraulic Main Pump (Cat. no. 20/925753) is a high-performance action pump engineered for JCB JS160W and similar excavator models. This piston-type pump delivers robust hydraulic flow (~63 cc/rev) at pressures up to 350 bar, ensuring smooth boom, arm, and travel functions even under heavy load. Built to match Kawasaki OEM specs, it offers seamless drop-in installation and is backed by quality assurance—available as brand-new, remanufactured, or aftermarket options.

   SPARKLING MACHINERY NEW EC950E 14681925 Fan is a core thermal management component exclusively for Volvo EC950E excavators (mining/heavy construction use). It dissipates heat from engines and hydraulic systems to prevent overheating, ensuring stable operation during long-hour heavy-load tasks. 
   Meeting Volvo OEM standards (14681925), it resists -30°C to 120°C temps, dust, and vibration, guaranteeing seamless EC950E compatibility and long-term reliable cooling performance.
