SPARKLING CAT 773E Parts – Quality, Precision, Reliability

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 349 352 5681695 Hose is a dedicated hydraulic fluid transfer component for Caterpillar 349 and 352 crawler excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "hydraulic fluid conduit" of the excavator, it efficiently transports high-pressure hydraulic oil between critical components like pumps, valves, and cylinders—ensuring stable oil supply for heavy-duty functions such as rock breaking, deep digging, and boom lifting, while eliminating leak risks that disrupt operations.
   Meeting Caterpillar OEM standards (part no. 5681695), it withstands 35 MPa working pressure, operates in -30°C to 95°C temperatures, resists hydraulic oil corrosion and external abrasion, and maintains flexibility for easy installation. Strict testing guarantees seamless compatibility with Caterpillar 349/352 and long-term hydraulic system reliability.

   SPARKLING MACHINERY NEW R140W7 R140W7A R140W9 ZTAM-00039 Differential Kit is a core undercarriage transmission component for Hyundai R140W7/R140W7A/R140W9 excavators (heavy-duty construction/mining use). It distributes torque to drive wheels while accommodating speed differences, ensuring stable turning and straight-line travel. 
   Meeting Hyundai OEM standards (ZTAM-00039), it resists -30°C to 100°C temps, wear, and mechanical shock, ensuring seamless compatibility and long-term reliable torque distribution performance.

   SPARKLING MACHINERY NEW F339202090180 Turbocharger is a high-performance engine enhancement component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As a core part of the machinery’s engine system, it compresses incoming air to increase oxygen density in the combustion chamber—boosting engine power output, improving fuel efficiency, and reducing exhaust emissions during high-intensity operations like heavy digging, load lifting, and continuous idling. This function is critical for maintaining the machinery’s operational efficiency under heavy loads, directly supporting productivity in construction, mining, and infrastructure projects while extending the engine’s service life by optimizing combustion.

   Engineered to match original equipment performance standards, it maintains stable compression efficiency even under harsh working conditions, including high engine temperatures, continuous vibration, and dust exposure. It resists turbine wear, oil leakage, and bearing failure, avoiding engine power loss or system breakdowns that could lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable power enhancement to support uninterrupted operation of compatible heavy-duty machinery.
