SPARKLING CAT Transfer Gear Repair – Precision Excavator Solutions

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.

   SPARKLING MACHINERY NEW KX121 KX161 U45 RD118-69402 Pump, Gear is a core hydraulic power component for Kubota KX121/KX161/U45 excavators (heavy-duty construction/mining use). It converts engine power into hydraulic pressure to drive actuators (arms, buckets), ensuring smooth operational movement. 
   Meeting Kubota OEM standards (RD118-69402), it resists -30°C to 100°C temps, pressure fluctuations, and wear, ensuring seamless compatibility and long-term reliable hydraulic power output.

   SPARKLING MACHINERY NEW EC200B EC210B EC220D VOE14640079 Hose is a dedicated flexible fluid transmission component for VOLVO EC200B, EC210B, and EC220D crawler excavators (widely used in construction, municipal engineering, and medium-scale mining). As a key part of the excavator’s hydraulic system, it transfers hydraulic oil between core components (e.g., pumps, cylinders, control valves) to ensure uninterrupted power delivery during tasks like digging, loading, and slope grading.
   Meeting VOLVO OEM standards (part no. VOE14640079), it endures 30 MPa hydraulic pressure, -35°C to 95°C temperatures, and repeated bending. Strict testing guarantees seamless compatibility with the three VOLVO models and long-term leak-free, reliable fluid transmission.
