This robust 6-blade fan spider assembly plays a vital role in maintaining optimal engine temperatures by efficiently driving airflow through the radiator and cooling system.

Crafted from durable materials to withstand demanding industrial environments, the fan spider ensures reliable performance and long service life. Its precision design promotes effective heat dissipation, helping to prevent engine overheating during heavy-duty material handling operations.

Whether you are replacing a worn-out fan or upgrading your cooling system components, this OEM-quality spider fan assembly fits perfectly and supports your machine’s consistent performance on the job site.

   SPARKLING MACHINERY NEW ZX27U-3 ZX27U-3F ZX29U-3 ZX29U-3F ZX30U-3 4679159 Wiper Motor is a dedicated visibility control component for Hitachi ZX27U-3, ZX27U-3F, ZX29U-3, ZX29U-3F, and ZX30U-3 mini crawler excavators (widely used in urban construction, garden maintenance, and narrow-space earthmoving). As the "cab visibility driver", it powers the windshield wiper to clear rain, dust, or mud from the glass—ensuring the operator has a clear view during tasks like small-scale digging, material loading, and landscape trimming, while enhancing operational safety in harsh weather.
   Meeting Hitachi OEM standards (part no. 4679159), it maintains stable rotational speed (30-40 rpm), endures -30°C to 80°C temperatures, resists moisture and vibration, and ensures low-noise operation. Strict testing guarantees seamless compatibility with the five Hitachi models and long-term wiper system reliability.

   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.

   SPARKLING MACHINERY NEW RD451-6405-0 Radiator is a critical cooling system component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s heat dissipation system, it efficiently transfers heat from engine coolant to the surrounding air—preventing engine overheating during high-intensity operations like prolonged digging, heavy-load lifting, and continuous idling in construction, mining, or infrastructure projects. This function is vital for maintaining the engine’s optimal operating temperature (typically 82–95°C), which directly influences fuel efficiency, power output, and long-term engine service life.

   Engineered to meet original equipment performance standards, it retains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and constant machinery vibration. It resists coolant leakage and internal blockages, avoiding cooling system failures that could lead to costly engine damage or unplanned downtime. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted machinery operation.
