1136603282 Original Excavator ISUZU ENGINE Fan for Hitachi

This product is usually a multi blade fan made of high-strength engineering plastics (such as fiberglass reinforced nylon) or aluminum alloy die cast. The blades are optimized for aerodynamics to provide sufficient air flow at lower speeds while reducing noise and power consumption. The center hub of the fan is equipped with mounting holes that match the crankshaft pulley, and is driven by a multi wedge belt (such as PK type) to synchronize the speed with the engine crankshaft. It has high balance accuracy and can withstand vibrations and centrifugal forces throughout the entire speed range of the engine. The blade design takes into account both wind pressure and air volume, ensuring effective heat dissipation even in harsh working conditions such as high temperature and high dust environments, and preventing engine overheating. Some models may integrate silicone oil clutches to achieve intelligent temperature control and speed regulation.

The original engine fan (part number 1136603282) is designed specifically for the ISUZU series diesel engine installed on Hitachi excavators, mainly used to drive cooling air through the radiator and intercooler. This fan is commonly used in medium-sized excavators equipped with engines such as ISUZU 6BG1, 4JG1, 4HK1, etc., such as Hitachi ZX200-3, ZX210-3G, ZX240-3G, as well as EX200-5, EX200-6 and other models. As a genuine original accessory, its universal number 1136603282 is the only identifier that ensures it matches perfectly with the installation holes of the engine crankshaft pulley, fan bracket, and shroud. Please provide the specific model and engine number of the host for verification when placing an order.

It is recommended to check the fan blades for cracks, deformation, or corrosion every 500 hours of work or every quarter, and clean the soil and oil on the surface of the blades. Check if the fixing bolts between the fan and pulley are loose, and if the belt tension is appropriate. If there is abnormal vibration or noise during the operation of the fan, it should be stopped immediately for inspection, and if necessary, dynamic balance correction or replacement with original parts 1136603282 should be carried out. When replacing, it is necessary to simultaneously check the status of the belt, tensioner, and water pump bearing. After working in cold regions, the ice and snow between the leaves should be cleared. During storage, direct sunlight and heavy pressure should be avoided to prevent plastic aging or metal corrosion. Regular maintenance can ensure the efficiency of engine heat dissipation and extend the service life of related components.
