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 A25D EC140C EC240C EW40D 960254 O-Ring is a dedicated sealing component exclusively engineered for VOLVO A25D articulated dump trucks, EC140C/EC240C excavators, and EW40D wheeled excavators—key equipment in construction, mining, and municipal infrastructure projects. As a critical part of the machinery’s hydraulic, fuel, and coolant systems, it creates tight, leakproof seals between mating components (e.g., hydraulic valve connections, fuel line joints, and coolant hoses). This function is essential for maintaining system pressure stability, preventing fluid leakage (hydraulic oil, fuel, coolant), and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like heavy hauling, digging, or road maintenance.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 32 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous machinery vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for VOLVO A25D/EC140C/EC240C/EW40D systems. Backed by strict performance verification, it guarantees consistent sealing support for these VOLVO models.

   SPARKLING MACHINERY NEW ZGAQ-05751/0501314381 Disc-Friction is a core braking component for Doosan excavators (heavy-duty construction/mining use). It generates friction with brake discs to achieve reliable stopping, ensuring operational safety and control. 
   Meeting Doosan OEM standards (ZGAQ-05751/0501314381), it resists -30°C to 300°C temps, wear, and thermal fading, ensuring seamless compatibility and long-term reliable braking performance.

   SPARKLING MACHINERY NEW EC200B EC210B EC240B EC240C FC2924C VOE14535458 Gear Pump is a dedicated hydraulic power component for VOLVO EC200B, EC210B, EC240B, EC240C crawler excavators and FC2924C compact equipment (widely used in construction, municipal engineering, and medium-scale earthmoving). As the "hydraulic power core" of the equipment, it converts engine mechanical energy into stable hydraulic pressure to supply high-pressure oil for key functions—such as boom lifting, bucket digging, and track steering—ensuring smooth operation during continuous work.
   Meeting VOLVO OEM standards (part no. VOE14535458), it endures 26 MPa working pressure, -30°C to 90°C temperatures, and resists oil wear and vibration. Strict testing guarantees seamless compatibility with the five models and long-term reliable hydraulic power output.
