   SPARKLING MACHINERY NEW R200W7 R170W7 31N6-10150 31N6-10160 Reduction Gear is a premium China-made transmission component specifically engineered for R200W7 and R170W7 wheel excavators. As a critical part of the power transmission system, it adjusts power output by converting high-speed, low-torque input into low-speed, high-torque motion, enabling efficient operation of key mechanical functions such as swing, travel, or auxiliary movements during construction, material handling, and industrial tasks.

   Designed to original equipment standards, it maintains stable power transfer and optimal torque conversion even under continuous operational stress and heavy loads. With optimized gear meshing design for minimal friction and wear, it adapts seamlessly to harsh working environments, from dusty job sites to rough terrain. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW PC490 708-1T-13440/708-1T-13610 Cylinder Block is a dedicated, high-strength structural core exclusively engineered for KOMATSU PC490 crawler excavators—heavy-duty equipment critical for large-scale mining, construction, and quarrying projects. As the foundational component of the excavator’s engine, it houses key moving parts (pistons, crankshafts) and forms the sealed chamber for fuel combustion, directly supporting engine power output and operational stability during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for preventing engine structural failure, maintaining consistent power delivery, and avoiding costly unplanned downtime that disrupts critical project workflows.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-1T-13440 and 708-1T-13610, the Cylinder Block withstands harsh working conditions: high combustion pressure (up to 18 MPa), extreme temperature fluctuations (-30°C to 120°C), and continuous vibration from heavy-duty use. It resists thermal deformation and mechanical wear, providing long-lasting structural reliability for KOMATSU PC490 excavators. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load engine tasks.

   SPARKLING MACHINERY NEW EC140 VOE14778022 Compressor is a premium China-made climate control component specifically engineered for EC140 excavators. As a key part of the cabin cooling system, it compresses refrigerant to maintain optimal temperature regulation, ensuring operator comfort and productivity in extreme weather conditions—from scorching construction sites to humid industrial zones.

   Designed to original equipment standards, it delivers consistent cooling performance with stable pressure output even under prolonged operation. With optimized structural design for minimal vibration and energy consumption, it integrates seamlessly into the EC140’s existing climate system. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted work cycles in harsh environments.
