Tensioner
The tensioner is a belt tensioning device used in the automobile transmission system. It is mainly composed of a fixed casing, a tensioning arm, a wheel body, a torsion spring, a rolling bearing and a spring bushing. It can automatically adjust the tension according to the different degree of tension of the belt. Tightening force makes the transmission system stable, safe and reliable. The belt is easy to be stretched after a long time of use, and the tensioner can automatically adjust the tension of the belt, so that the belt runs more smoothly, the noise is reduced, and it can prevent slipping.

timing belt

The timing belt is an important part of the engine's air distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The use of belts rather than gears for transmission is due to the fact that belts are less noisy, precise in transmission, have little variation in themselves and are easy to compensate. Obviously, the life of the belt must be shorter than that of the metal gear, so the belt should be replaced regularly.

Idler

The main function of the idler is to assist the tensioner and belt, change the direction of the belt, and increase the inclusion angle of the belt and the pulley. The idler in the engine timing drive system can also be called a guide wheel.

The timing kit contains not only the above parts, but also bolts, nuts, washers and other parts.

Transmission system maintenance

The timing drive system is replaced regularly

The timing transmission system is an important part of the engine air distribution system. It is connected with the crankshaft and cooperates with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. Usually consists of tensioner, tensioner, idler, timing belt and other accessories. Like other auto parts, automakers clearly specify a regular replacement period for the timing drivetrain at 2 years or 60,000 kilometers. Damage to the timing drive system parts will cause the vehicle to break down during driving and, in severe cases, cause damage to the engine. Therefore, the regular replacement of the timing drive system cannot be ignored. It must be replaced when the vehicle travels more than 80,000 kilometers.

Complete replacement of timing drive system

As a complete system, the timing drive system ensures the normal operation of the engine, so a complete set of replacement is also required when replacing. If only a single part is replaced, the condition and life of the old part will affect the new part. In addition, when the timing transmission system is replaced, the products of the same manufacturer should be selected to ensure the highest matching degree of parts, the best use effect and the longest life.
