   SPARKLING MACHINERY NEW 312E 320E 324E 2566454 Temperature Sensor is a dedicated precision monitoring component exclusively designed for 312E, 320E, and 324E excavators. As a core part of the excavators’ engine and hydraulic system monitoring, it real-time detects critical temperature data—such as engine coolant temperature and hydraulic oil temperature—and transmits accurate signals to the operator’s control panel. This function is critical for preventing overheating during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance, directly ensuring stable engine power output, protecting hydraulic components from thermal damage, and avoiding unplanned downtime caused by temperature-related failures.

   Engineered to match original equipment performance standards, it maintains high detection accuracy even under harsh working conditions, including extreme temperatures (-30°C to 120°C), continuous excavator vibration, and exposure to dust or hydraulic oil. It resists signal interference and corrosion, avoiding data errors that could lead to misjudgments of the excavator’s operating status. Backed by strict performance verification, it guarantees reliable temperature monitoring to support uninterrupted operation of 312E/320E/324E excavators.

The ZF 4143325094 Input Housing (also known as 4143-325-094 or 4143.325.094) is an essential transmission component designed specifically for John Deere wheeled excavators including models 190DW, 230GW, 220DW, and 190GW. Manufactured with high-grade materials and advanced machining, this housing ensures optimal alignment and secure connection of the input shaft to the transmission system.

Its robust construction delivers superior resistance to vibration, impact, and wear, making it a dependable choice for heavy-duty applications. Whether you're replacing a worn part or upgrading to maintain performance, this input housing provides a reliable fit and long service life.

   SPARKLING MACHINERY NEW PC400 PW400MH 6151-12-1101 Cylinder Head is a premium China-made engine component specifically engineered for PC400 and PW400MH heavy machinery. As a critical part of the engine system, it seals the top of the cylinder block, houses valves, and maintains compression within combustion chambers, ensuring efficient fuel combustion and optimal engine power output in construction, mining, and industrial operations.

   Designed to original equipment standards, it maintains precise sealing performance and heat resistance even under high-temperature and high-pressure operating conditions. With optimized structural design for durability and thermal management, it adapts seamlessly to harsh working environments, from dusty job sites to heavy-load operations. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
