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.

The CATERPILLAR 441-9224 Transfer Gear Yoke Assembly (also listed as CA4419224 or 4419224) is a heavy-duty drivetrain component designed for use in Caterpillar off-highway trucks and track-type tractors, including models 773E, 775G, 775F, 773D, 773G, and D10R.

This transfer gear yoke assembly plays a critical role in the power transmission system, connecting rotating components within the transfer gear and ensuring smooth torque delivery from the engine to the driveline. Built to endure high loads, vibrations, and rugged working conditions, the 441-9224 yoke assembly helps maintain drivetrain alignment and reliability, even under extreme duty cycles.

Manufactured to OEM specifications, this component guarantees a precise fit, excellent durability, and long-term performance—making it a trusted replacement choice for Caterpillar heavy equipment operating in mining, quarrying, and construction environments.
