In engines with high frequency of rotation, installed in passenger and light commercial vehicles, a metal chain of the timing chain is usually used. It is inside the engine, lubricated with engine oil and connects the crankshaft with distribution — the latter controls the operation of intake and exhaust valves. Gradually, during long-term operation, the chain is stretched. Accordingly, this can lead to a violation of the synchronization of the rotation of the distribution and crankshaft, resulting in a violation of the synchronization of intake and exhaust valves, a decrease in the engine power, an increase in the number of harmful emissions in the exhaust gases, which will lead to the engine failure. The stretching of the drive chain may occur due to the wear of various parts.

Wire of the chain — as a rule, due to wear of rollers and sleeves. Asterisks — due to wear of surface contact surfaces with chain. Tensioner — over time, the rigidity is reduced, which leads to an irregular tension of the chain.

The tensioner and guides wear out with the wear of other components that cut the grooves on the surface of the guide. Since the improvement of the engines occurs in the direction of decline in their mass, reduce the working volume and increase the capacity, the connecting components are subjected to increased loads, especially in highly powerful economical diesel engines and gasoline engines with direct injection.

The tightening of legislation in the field of harmful gas emissions in the exhaust gases requires the use of relevant technologies, such as start-stop and hybrid systems, and also places increased requirements for the wear resistance of the timing chain. A constant voltage from rotation of the chain and gears, dynamic loads as a result of the combustion of the fuel inside the cylinders, as well as the degradation of engine oil leads to wear.

The acceleration of the wear chains can occur under the influence of various factors, including the repeated swinging movements of slave links or sleeves with respect to fixed connecting rollers, as well as the presence of an excess amount of soot and acids in oil and friction about other components of the gas distribution mechanism.

As the chain wear out between surfaces in direct contact, a sag is formed, which leads to the elongation of the chain and, accordingly, to change the gearing step. This is found in rollers and supports of the roller chain, as well as in rollers and connective plates of links, which over time leads to weakening and subsequent destruction of the chain drive.

The SWAG timelines sets are implemented the latest technical developments and upgraded components are used, such as reinforced guide chains with an optimized surface structure, as well as excellent timing chain chain with Tritan® coating. This coating contributes to the improvement of tribological properties and, as a result, reduce the wear rate and optimize fuel consumption. The sprockets included in the kit are designed to reduce the load on the chain and tensioners and are distinguished by the increased efficiency of quenching vibrations.

Remkomplekt SWAG timing chain has a coating that significantly reduces friction, helps to reduce noise and vibrations, and also distinguishes with increased strength and low surface roughness, which helps reduce fuel consumption.

You can rely on the proven SWAG spare parts that are not inferior in the quality of the original components. The entire range of SWAG timing chains can be found on the website:
