SPARKLING Construction Machinery Gear – Durable Excavator Parts

The K9001469 Bevel Gear is a critical drivetrain component specifically engineered for DOOSAN wheeled excavators including models DX140W, DX170W, DX190W, and SOLAR 185W-V. It is designed to efficiently transmit power between intersecting shafts at precise angles, enabling smooth and reliable torque delivery in the swing or travel reduction gear systems.

Manufactured with premium-grade alloy steel and finished with precision gear-cutting technology, this bevel gear ensures high wear resistance, quiet operation, and extended service life — even in rugged construction environments.

   SPARKLING MACHINERY NEW LC00159 Gear Box is a premium China-made power transmission component designed for compatible construction machinery, including wheel loaders, excavators, and compact utility vehicles. As the "power distribution core" of the machinery’s drivetrain, it converts and transmits torque from the engine to the wheels or working mechanisms (e.g., bucket lifts, arm rotations), enabling smooth speed adjustment and torque amplification. This ensures the machinery delivers optimal power for diverse tasks—such as heavy material hauling, site leveling, and precision lifting—in construction, agriculture, and warehouse logistics scenarios.​
   Engineered to original equipment standards, it maintains stable transmission performance even under harsh working conditions: high torque loads, continuous vibration, dust ingress, and temperature fluctuations (-25°C to 90°C). With precision-machined gears (for minimal friction) and a sealed lubrication system (to prevent oil leakage), it minimizes wear and extends component life. Backed by strict quality verification, it guarantees reliable power transfer to support uninterrupted machinery operation and reduce downtime caused by drivetrain failures.

   SPARKLING MACHINERY NEW VOE14561971 VOE14561970 Gear Pump is a critical hydraulic power component designed for compatible construction machinery, such as excavators and loaders. As the "hydraulic power source" of the machinery’s hydraulic system, it converts mechanical energy from the engine into hydraulic energy by generating stable oil pressure and flow. This hydraulic energy drives key working mechanisms—including boom lifting, bucket digging, and arm rotation—ensuring smooth, powerful operation during heavy-duty tasks like construction earthmoving, mining loading, and infrastructure construction.

   Engineered to match original equipment performance standards, it maintains reliable hydraulic output even under harsh working conditions, such as high-pressure loads, continuous vibration, and temperature fluctuations. It prevents oil leakage and pressure loss, avoids inefficient hydraulic operation caused by flow instability, and safeguards the integrity of the entire hydraulic system. Backed by strict performance verification, it guarantees long-term stable power supply to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW R290LC7A RD340LC-7 39Q8-42100 39Q8-42102 Travel Reduction Gear is a premium China-made transmission component specifically engineered for R290LC7A and RD340LC-7 excavators. As a critical part of the travel system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling steady and powerful movement across diverse job sites, from rough terrain to heavy-load operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous operational stress and uneven ground conditions. With optimized gear meshing design for minimal wear and energy loss, it adapts seamlessly to harsh working environments, from construction zones to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
