Wholesale Fan Coupling Assembly Essential Cooling System Clutch New Parts160802010005B Concrete Pump D12C5 Engine Tongming Brand

This product is an electronically controlled silicone oil clutch fan assembly, which is the core heat dissipation component of heavy-duty commercial vehicles and construction machinery engines. The fan speed is intelligently controlled by the engine ECU to achieve precise temperature control, fuel saving and noise reduction, and is compatible with China VI emission diesel/gas engines.

11 fan blades Fan diameter 660-720mm (customized according to vehicle model) Working temperature range -40 ℃~+120 ℃ Control signal type PWM/duty cycle signal Suitable engine power range of 200-560 horsepower Material: Fiberglass reinforced nylon blades+aluminum alloy clutch housing

Installation steps 1 Align the clutch body with the engine drive shaft, evenly cross lock it with 8 M8 bolts, and control the torque at 25-30N m2Align the fan blades with the clutch flange and secure them with bolts (if it is a split structure) 3 Connect the electrical control harness plug to ensure that the buckle is securely fastened, avoiding looseness and water ingress 4 Check that the gap between the fan blades, water tank, and fan cover is ≥ 10mm to prevent interference during operation

Operation and usage 1. Normal operating conditions -Low temperature/idle: The fan idles with the clutch, with a speed of about 10% -30% of the engine, reducing power loss. -Medium high temperature/driving: When the engine water temperature rises above 85 ℃, the ECU outputs a control signal, and the fan speed gradually increases, reaching a maximum of over 90% of the engine speed. -High temperature/heavy load: Under climbing and full load conditions, the fan runs at full speed to quickly remove heat and ensure that the engine does not overheat. 2. Precautions -It is forbidden to forcibly disassemble the fan when the engine is hot to avoid burns and component damage. -Do not touch the running fan with your hands to prevent injury caused by entanglement.
