SPARKLING CAT C13 Coupling – Durable & Precise Excavator Part

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.
