490 Engine Fan Blade for Forklift — Universal Cooling Fan for Xinchai 490 Series Diesel

The 490 engine fan blade is a universal replacement cooling fan designed for the Xinchai 490-series 4-cylinder diesel engines used across HELI, Hangcha, Dalian, and Lonking 2T-3.5T counterbalance forklifts. The fan blade is the sole source of forced-air cooling during the 70-80% of forklift operating time spent stationary or at low travel speeds during lifting, stacking, and loading operations — there is zero ram-air contribution at these times. The 490-series engine fan draws ambient air through the radiator core at a flow rate determined by engine RPM and blade geometry, creating the pressure differential that enables the radiator to reject 25-35 kW of combustion heat to the atmosphere. This is genuine OEM aftermarket replacement manufactured to factory specifications for blade pitch angle, diameter, hub bore, and bolt pattern matching the 490 engine water pump flange.

The fan blade is injection-molded from glass-reinforced polypropylene (PP-GF) for high tensile strength at the blade roots where centrifugal stress concentrates, combined with low rotational inertia that minimizes water pump bearing loading compared to steel fan blades. The six-blade configuration with variable-pitch airfoil cross-section optimizes airflow at the engine governed speed of 2,200-2,400 RPM while balancing noise output for operator hearing protection. The hub features a precision-bored pilot hole and four mounting bolt holes on the standard 490 engine water pump flange bolt circle. Forklift fan blade category.
