Timing belt is an important detail of the gas distribution (timing) valve mechanism. It is necessary for the camshaft drive. The timing belt is located outside the crankcase and holds on the cogwheels of the camshaft and the crankshaft. It is made of polymer, compacted with a steel wire frame. There is no need to tighten this belt, or to grease it. The timing belt consists of an outer layer of tissue, an upper layer of rubber-gasket, an elastic rubber cord, a lower gasket-layer and an inner rubber layer.

Timing belts are produced as a whole structure, one- and two-sided and of any length. The main characteristics of the timing belt are the tines modules, the distance between them and the type. The most commonly used timing belts are with a rounded profile and in the form of a trapezoid. The timing belts with a rounded profile transmit more torque and power than the ones in the form of a trapezoid. When using these timing belts the tension in the belt and the tensile force are distributed more evenly by girth tension force in the pulley. Rounded tooth profile ensures a smooth and uniform mesh. Timing belts with a profile in the form of a trapezoid are usually produced in the range of modules from 1 to 10 millimeters, and timing belts with rounded teeth are manufactured with a module of 3 to 5 millimeters.

Timing belts usually serve until 100 000 km. However, the driver should take care of keeping this part in a good condition. If you need to replace the timing belt, you can buy it in our online store directly from the manufacturer, who has a reputation of a reliable supplier of high quality auto parts made of most advanced materials. We will deliver your order in the shortest time and at an affordable price, as well as any other car part, such as pulse sensor or trunk lid.

What you need to know about timing belt replacement: lifetime limits, common defects and their signs, tips and recommendations

Service life of the timing belt can vary for cars of different brands and models. Averagely, the component is to be replaced every 80 000 – 100 000 operational kilometers.

In most cases this device breaks down because of wear out. The component should be replaced in case of its oiling, for example, when greasing material leakage takes place. Jamming of rollers or a pump can cause timing belt breakage or damage.

With component broken, the engine stalls at once. In this case attempts to start it again fail. It is impossible to detect belt wear out by indirect signs: diagnostics is required to assess its condition. Checking should be entrusted to specialists: only professional examination allows to find out defects in time. During diagnostics the timing belt is removed from the car and turned inside out. Thus, you can find cracks, delamination, lack or wear out of teeth, wear out of the area between teeth, edges rounding, wear out of fabric basis fiber.

Specialists recommend replacing the timing belt together with the idler and tensioner pulleys. Otherwise there is high probability of fast wear out of a new component. That is why it is practical to buy the timing belt and rollers kit. The kit can contain other components such as a pump or seals. The timing belt kit must be installed at a service station. This work requires professional skills, so it is not recommended to perform it on your own.
