Engine pulley,OKX Wallet Sign up also known as winding wheel and torsion wheel, is an important part of the engine. Its function is to convert the engine speed into a larger torque, so that the car engine can operate normally to provide sufficient power. Due to the importance of the engine pulley, it must be replaced in time when it is abnormally worn, loose, etc. Next, we will explain in detail the function of the engine pulley and the replacement method. I. The function of the engine pulley The engine pulley is composed of a set of rims and gear belts (belts).The belt is a yellow rubber belt, which runs on more than three rollers. The engine pulley plays a crucial role in the rotation of the engine and can provide the necessary torque for the power system. Specifically, the function of the engine pulley can be summarized into the following three points: 1. Convert the speed of the engine: When the car is driving, the engine speed needs to be changed to a larger torque to exert sufficient power. The engine pulley can convert the engine speed into a greater torque by connecting it to the gear belt. Two. Drive other parts of the car: The engine pulley can not only drive the engine itself, but also other parts such as generators, pumps, air conditioners and compressors. Therefore, the state of the pulley is directly related to the overall performance of the car. 3. Achieve engine reliability: One of the main functions of the engine pulley is to provide reliability for the power system.If the belt pulley is abnormally worn or loose, it will directly harm the normal operation of the engine, and in serious cases, it will even cause a chain reaction, causing the whole vehicle to be unable to operate. II. How to replace the engine pulley 1. Check in advance: Before replacing the engine pulley, you need to check the condition of the pulley and gear strap. If there is damage, deformation, cracking, etc., it must be replaced in time. Two. Remove the original pulley: Remove the original pulley from the vehicle. It is recommended to pay attention to protecting the surrounding parts during the disassembly process to avoid additional damage. 3. Cleaning and wiping: Before cleaning the new pulley, you need to clean the original pulley and wipe it with a clean cloth to ensure that its surface is clean. This helps to extend the service life of the new pulley. Four. Replace the new pulley: Install the new pulley into the car and use wrenches and screws to fix the pulley to the engine.It should be noted that during the installation process, it must be installed according to the model of the vehicle and the requirements of the vehicle manufacturer. 5. Test: After installing the pulley, it needs to be tested. When the engine is running, observe whether the pulley rotates normally, and listen to whether there is an obvious abnormal sound. If there is any abnormality, you need to stop testing the vehicle and check whether the belt pulley is installed correctly. In a word, the role of the engine pulley is very important, and its reasonable use and replacement must be paid attention to. When the engine pulley twitches, the engine shakes, the pulley loosens, slips and other phenomena, it should be checked and replaced in time. If you have no experience, it is recommended to go to a professional repair shop for repair. This helps to extend the life of the vehicle and ensure your driving safety.
