When is it necessary to replace the timing chain and what is this tool?

Chain of gas distribution mechanism (abbreviated GRM) is a simple, but at the same time an indispensable detail, without which it is impossible to move any modern car. It synchronizes the rotation of the camshaft with the crankshaft, thereby contributing to the coherent work of the ICE. The only thing that can put this is the uneven supply of gasoline to the engine. But about this a little later, and today we'll look at what time period the car needs to replace the timing chain, and also what consequences the breakage of this part leads to.

Why change it?

This part, like the engine, assumes enormous loads when operating. After a few thousand kilometers, it can simply tear. But the deformation may be incomplete. In the case when at least one tooth breaks out of the mechanism, the entire chain begins to slip, there are disruptions in the engine operation. In addition, this device is placed in the motor so that even the slightest error in operation can lead to the most unpredictable consequences. Therefore, the timing chain should be replaced in a timely manner. It is advisable to carry a spare part in the trunk, especially if you like long trips.

What happens if you do not make a replacement on time?

Often the absence of even one tooth in this part leads to damage to the valves, repair of which takes a lot of time and money. As for diesel engines, the most significant risk is to the distributing shaft. In this case, you will have to repair not only it, but also the valves, and also to change the cylinder head gasket. All this, as you have already understood, is worth a lot of money.

Nuances when changing parts

It is worth noting that the replacement of the timing chain VAZ 2107-2110 - a fairly long process, which can take away from you all day (at least 8 hours). By the way, besides the chain itself, you will have to buy new tension rollers. To save on them it is not necessary, because because of poor-quality details the replacement of the timing chain will be very, very fast, and not the fact that the car will travel 100 kilometers before.

Service life

This characteristic directly depends on the brand of the car. For example, the replacement of the timing chain VAZ is made every 50-60 thousand kilometers. But do not expect that the part will serve exactly 60 thousand. Therefore, at least every month you need to check the condition of this part. But on many modern machines, it is not possible to check the current state of the chain visually, so some cars are equipped with special sensors on the instrument panel, which signal the possible breakdown of this part.

A useful tip for those who recently purchased a used car

If you bought a used car, SUV or truck, be sure to replace the chain. Moreover, you need to do this even if before the sale the previous owner assured you that she was recently changed. Thus, the risk of breakage of the camshaft and valves will be reduced to zero, and the car will pass more without breakages (especially if it is bought 500 kilometers from the house).
