SPARKLING CA4419224 – High-Quality Excavator Part

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 EC200D 14730968 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC200D crawler excavators—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As a core protective component for the excavator’s hydraulic system, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, debris, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during tasks like trench digging, material loading, and site grading.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 35 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous excavator vibration. It resists oil aging and wear, providing long-lasting protection for the EC200D’s hydraulic system. Backed by strict performance verification, it guarantees uninterrupted sealing support for VOLVO EC200D excavators.

   SPARKLING MACHINERY NEW SK485-9 DX420 DX480 472-0209 Crankshaft is a dedicated power transmission core component for Weichai-powered excavators, including SK485-9, DX420, and DX480 models (widely used in heavy construction, mining, and large-scale earthmoving). As the "engine power converter", it converts the reciprocating motion of engine pistons into rotational motion—driving key excavator systems like hydraulic pumps and generators to ensure stable power output during high-intensity tasks such as rock breaking, deep digging, and heavy lifting.
   Meeting Weichai OEM standards (part no. 472-0209), it maintains precise rotational balance, endures -30°C to 150°C engine temperatures, resists wear and vibration, and ensures long-term structural stability. Strict testing guarantees seamless compatibility with the three Weichai-powered excavator models and reliable engine operation.

The 709-63-11501 / 709-63-11600 Control Valve Assembly is a precision-engineered hydraulic component specifically designed for Komatsu D375A series bulldozers. As a key part of the machine’s hydraulic system, this valve ensures smooth, accurate, and responsive blade and ripper control—essential for productivity in high-demand mining, earthmoving, and large-scale construction environments.

Manufactured with robust materials and OEM-level quality control, our replacement control valve delivers stable pressure regulation, excellent sealing performance, and long service life, even under continuous heavy-duty operation.
