Skip timing belt

Belt performs important mission in the car and the reliability of its work depends on the durability and safety of the engine.

On some models, the engine broken belt or slippage when the timing belt skipped a few teeth on the crankshaft or camshaft pulley can cause severe damage.

If skipping even when the timing belt is no emergency, the engine begins to run rough or stall at all.

This is due to the fact that stray timing cycle is disturbed and supply of fuel and purge cylinder. Typically, these cases occur when the timing belt gets oil or antifreeze. This can be potekshaya pump or disrupt the gland of one of the shafts. On the front-VAZ 2108-09 and their modifications are sometimes the cause of getting the oil in the area of ​​operation is the timing belt potekshy oil pressure gauge located on the top left of the belt cover.

Therefore, as the belt is necessary to focus on, namely; not to leave until later appeared fresher suspicious spot in the region of the belt cover. Sometimes the "later" can not be, since even a small amount of oil can create conditions so that skipped belt.

If no visible traces of oil or antifreeze is not observed, and the motor, however, behaves in an unusual way, i.e. Turnover does not develop, difficult to start or stalls frequently - Remove the timing belt cover and ensure the correct tagging.

When replacing the timing belt Always ensure the accuracy of its installation on the factory label. "Hit by" even one tooth belt mark is necessarily adversely affect the operation of the engine, and on some models, it will be impossible to launch, as will be shot down timing. This especially applies to diesel engines, which are very sensitive to inaccuracies belt installation.

Putting the engine at the factory marks, start the installation of the belt with a long free hand, immediately giving him a preload, and then to lay it on through the rollers. The teeth of the timing belt should be exactly at the same time fall into depression pulleys, if this is not possible, a little slide crankshaft or camshaft, tooth belt to lay down clearly in the groove on a pulley. After installing again, check the labels match, having turned the crankshaft two turns.
