SPARKLING 775F Transfer Components

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 EC290B 14575661 Hydraulic Pump is a premium China-made power component specifically engineered for EC290B excavators. As the core of the hydraulic system, it converts mechanical energy into hydraulic pressure, driving critical operations such as boom lifting, arm articulation, and bucket movement through controlled fluid flow. This ensures efficient power transmission and responsive machinery performance in construction, mining, and heavy-duty earthmoving applications.​
   Designed to original equipment standards, it maintains stable pressure output and consistent flow rates even under continuous high-load operation. With optimized internal design for minimal energy loss and enhanced wear resistance, it adapts seamlessly to harsh working environments, from dusty job sites to high-temperature conditions. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation.

The Caterpillar Coupling-Pump (Part No. 267-1082 / CA2671082 / 2671082) is a high-quality aftermarket replacement part made in China, engineered to fit CAT mini hydraulic excavators such as 305C CR, 305.5E, and certain Caterpillar wheel loader models.

This coupling serves as a crucial link between the engine and hydraulic pump, ensuring efficient power transmission while absorbing vibration and reducing stress on connected components. Built from durable elastomeric and metal materials, it offers excellent torsional flexibility and resistance to wear — helping maintain optimal machine performance.

If you're looking for a cost-effective yet reliable alternative to OEM parts, this China-made coupling is a smart choice for equipment maintenance and repair, without compromising functional integrity.

   SPARKLING MACHINERY NEW R260LC9S R290LC9 R290LC9MH R320LC7 R330LC9S XKBF-01503 Valve Assy is a dedicated hydraulic control assembly for Hyundai R260LC9S, R290LC9, R290LC9MH, R320LC7, and R330LC9S crawler excavators (widely used in heavy construction, mining, and infrastructure projects). As the "hydraulic control center" of the excavator, it integrates multiple valves to regulate oil flow, pressure, and direction—powering key functions like boom lifting, bucket digging, and swing movements, ensuring smooth and precise operation during high-intensity tasks.
   Meeting Hyundai OEM standards (part no. XKBF-01503), it endures 32 MPa working pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains leak-free performance. Strict testing guarantees seamless compatibility with the five Hyundai models and long-term hydraulic system stability
