We change the timing belt on the car "Lada Priora"

Gas distribution in the car "Lada Priora", as in any other car, from time to time requires diagnosis and repair. In particular, we are talking about the belt itself. Untimely replacement of this element and, consequently, its breakage can lead to costly repairs. Now we will tell you how the timing belt is replaced on the "Priora" and why it is needed (avtozam.com/vaz/lada-priora/zamena-remnya-grm).

What is it for?

The strap of the mechanism is necessary in order for the crankshaft and camshafts of the engine to function synchronously. This is very important, as this determines the intake of gasoline and the removal of exhaust gases from the system.

When is it necessary to change?

In some cases, an unplanned replacement of the strap may be required. For example, if you find traces of engine oil on it. If this is the case, the cause of the leakage should be eliminated and the element replaced. In addition, if there are mechanical damages on the belt, which can cause a breakage, the part must also be changed to a new one. Alternatively, if the denticles began to fall off the timing belt, this can also cause an immediate replacement of the component.

Phased replacement

All work on the replacement of the parts should be carried out on a cooled engine.

1. First you need to dismantle the plastic protection element. Use a wrench to unscrew the pins and remove the cover.

2. Then set the first motor cylinder to the upper position. It is necessary to make so that marks on cam-shafts coincide with marks on a plastic casing.

3. Make sure that the marks on the crankshaft coincide with the marks on the oil pump.

4. Take the wrench and unscrew the screws that secure the tension rollers.

5. Using a screwdriver, dismantle the timing belt. Check the position of the marks on the shafts. If they have moved, they should be re-set.

Remove the component and replace it with a new one.

6. Now carefully, so that the marks do not go off again, install a new mechanism strap. Using the roller, the element should be tightened. Then check the position of the marks again.

7. Reassemble in the reverse order.

8. Now check the tension. It is recommended to rotate the crankshaft in a circle for several turns, after which again check the position of the marks.

9. The belt tension itself should be checked in the middle of the two rotating pulley disks. The belt should not bend more than 6 mm. If the element is over-stretched, you will hear a characteristic sound. This, in turn, will significantly affect its service life.
