   SPARKLING MACHINERY NEW BX70, BX70D, EX100 EX100M EX120 894449-6450 Oil Cooler Cover is a dedicated protective component for Hitachi BX70, BX70D, EX100, EX100M, and EX120 excavators (widely used in construction, mining, and municipal engineering). As the "oil cooler guardian", it shields the excavator’s oil cooler from external impacts, dust, and debris—maintaining efficient heat dissipation of hydraulic oil and engine oil during tasks like digging, lifting, and rock breaking, while preventing cooler damage that causes system overheating.
   Meeting Hitachi OEM standards (part no. 894449-6450), it endures -30°C to 110°C temperatures, resists corrosion and vibration, and ensures tight fitting with the cooler assembly. Strict testing guarantees seamless compatibility with the five Hitachi models and long-term oil cooler protection.

   SPARKLING MACHINERY NEW ME990328/60289472 Water Pump is a critical cooling system component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core power source of the machinery’s coolant circulation system, it drives engine coolant to flow through radiators, engine blocks, and other heat-generating components—effectively transferring excess heat and maintaining the engine’s optimal operating temperature (typically 82–95°C). This function is vital for preventing engine overheating during high-intensity operations like prolonged digging, heavy-load lifting, and continuous idling in construction, mining, or infrastructure projects, directly safeguarding engine power output, fuel efficiency, and long-term service life.

   Engineered to match original equipment performance standards, it maintains stable coolant flow rate and pressure even under harsh working conditions, including high ambient temperatures, continuous machinery vibration, and exposure to dust or coolant contaminants. It resists leakage, bearing wear, and impeller damage, avoiding cooling system failures that could lead to costly engine repairs or unplanned downtime. Backed by strict performance verification, it guarantees reliable circulation performance to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW 320 323 336 345GC 512-1242 Grip AS RH 526-8848 Grip AS LH Sensor is a dedicated operational control sensor for Caterpillar 320, 323, 336, and 345GC crawler excavators (widely used in construction, mining, and infrastructure projects). As the "handheld control feedback core", it detects the position, pressure, and operation state of right-hand (RH) and left-hand (LH) control grips—transmitting real-time signals to the excavator’s control unit to ensure precise adjustment of boom, bucket, and swing functions during high-intensity tasks, while enhancing operational safety.
   Meeting Caterpillar OEM standards (part nos. 512-1242 & 526-8848), it achieves ±0.2% detection accuracy, endures -30°C to 85°C temperatures, resists oil and vibration, and maintains stable signal transmission. Strict testing guarantees seamless compatibility with the four Caterpillar models and long-term control system reliability.
