YA00007116 BELT For HITACHI ZX250-5B 4HK1

The belt is a device used to drive power and has important uses for the engine. It performs various functions by transferring the power of the engine to different mechanical components. The main function of the engine belt is to ensure the normal operation of the engine. The timing belt may also be responsible for other tasks, such as in some models, it is also responsible for driving components such as water pumps. Therefore, regular inspection and replacement of the timing belt is essential to maintain engine performance and extend its service life.

The engine belt plays a crucial role in the engine distribution system. It ensures precise control of intake and exhaust times through its connection with the crankshaft and with a specific transmission ratio. Specifically, the timing belt is an important part of the engine distribution system, through the connection with the crankshaft, to ensure the accuracy of the inlet and exhaust time. The use of belt rather than gear for transmission is because the belt has the advantages of low noise, high transmission accuracy, small changes in itself and easy adjustment. The timing belt usually needs to be replaced after 60 to 80 thousand kilometers to ensure the normal operation of the engine.

The core function of the engine belt is to ensure the normal operation of the engine valve system, through the connection with the crankshaft, precisely control the intake and exhaust time, reduce engine vibration and noise, improve fuel economy. ‌ Engine belts are made of high strength rubber and fiber materials and consist of timing belts, crankshaft belts, camshaft belts, tension wheels, guide wheels and other components that work together to ensure the proper operation and coordination of the internal engine components.
