Purpose of timing belt is to connect the crankshaft and camshaft, which contributes to the coordinated work of units of the machine.
If not, the engine may fail.
The most common reasons for a rupture of the belt, the following:
- On cars of foreign production, the belt can serve as a fairly long time, about 150 thousand kilometers, but each part has its own lifespan. During long-term operation occurs abrasion of parts, which can lead to rapid tear. Special attention should be paid to the condition of the belt in the second-hand cars because their life is much less.
- The second reason for the gap of the belt may be the failure of the idlers. The purpose of this device – not to allow the cloth to fall off of the gears. It also has its share of work, therefore, the appearance of background noise will require the mandatory replacement of bearings.
- One of the most common faults on cars of the Russian production is failure of the pump.
- Quite often the reason for the gap becomes abrasion rubber teeth at the connection with the camshaft. In the absence of starting the machine or changes in operation of the engine, you should test the integrity of the teeth on the belt.
