SPARKLING D10R Drivetrain Parts – Durable Excavator 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.

The LQ15V00015F2 / LQ15V00015F1 hydraulic motor is a high-performance travel motor designed for KOBELCO SK260, SK250LC-6E, SK250-8, and SK260-8 excavators. Engineered for exceptional durability and torque transmission, this motor ensures smooth and efficient travel drive operation even in the most demanding working environments.

Whether you’re involved in construction, mining, or earthmoving operations, this hydraulic motor offers OEM-level compatibility, low internal leakage, and excellent responsiveness—delivering consistent power and high reliability over long periods of heavy use.

   SPARKLING MACHINERY NEW WB93R WB93S WB97R WB97S 42N-03-11320 Fan is a dedicated cooling system component exclusively designed for WB93R, WB93S, WB97R, and WB97S wheel loaders. As a core part of the loaders’ heat dissipation system, it works with radiators and oil coolers to generate consistent airflow—effectively dissipating heat from the engine, hydraulic oil, and transmission system during heavy-duty operations like material loading, site grading, and construction waste handling. This function is critical for maintaining the loaders’ optimal operating temperature range, which directly ensures stable power output, fuel efficiency, and long-term service life of key mechanical components.

   Engineered to match original equipment performance standards, it maintains reliable rotational speed and airflow output even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous machine vibration. It resists blade deformation and motor failure, avoiding cooling inefficiencies that could lead to overheating or unplanned downtime. Backed by strict performance verification, it guarantees long-term reliability to support uninterrupted operation of WB93R/WB93S/WB97R/WB97S wheel loaders.

   SPARKLING MACHINERY NEW EC250D EC250E EC300D EC300E PL3005D 14591251 Relief Valve is a dedicated hydraulic safety component for VOLVO EC250D, EC250E, EC300D, EC300E, and PL3005D crawler excavators (heavy-duty equipment for mining, large-scale construction, and infrastructure projects). As the core safety guard of the hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during rock breaking, bulk ore loading, and deep excavation.

   Meeting VOLVO OEM standards (part no. 14591251), it endures 34 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing seamless compatibility and safe operation.
