SPARKLING Gear Reduction Unit for Excavators

SPARKLING MACHINERY offers the KTC0185/KTC10240 gear reduction unit for CX460 and CX470B excavators, ensuring smooth torque transfer and durability under heavy-duty use. Built with high-strength materials and tested for OEM fit, it delivers reliable performance with fast global shipping and expert support.

   SPARKLING MACHINERY NEW 4921684 Position Sensor is a premium China-made electrical measurement component designed for compatible construction machinery (such as excavators, loaders, and bulldozers). As a critical part of the machinery’s control and monitoring system, it accurately detects the real-time position of key moving components—including boom arms, bucket links, or undercarriage parts—converting mechanical position signals into precise electrical data. This data is transmitted to the main controller to enable functions like automated position calibration, operational limit protection, and smooth actuator control, which are essential for preventing component collisions, ensuring task precision, and enhancing overall operational safety in construction, mining, and earthmoving scenarios.

   Engineered to original equipment standards, it maintains consistent measurement accuracy even under harsh working conditions, such as intense vibration, dust accumulation, and temperature fluctuations (from -40°C to 85°C). With a rugged structural design and anti-electromagnetic interference (EMI) technology, it resists environmental wear and signal distortion. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery position monitoring and reduce downtime caused by position-related control failures.

   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.
