Advice 1: How to change the timing belt for VAZ

Belt tensioner (belt tensioner) is a closed rubber belt, on the inner side of which is slotted. Its purpose is to synchronize the camshaft and the crankshaft of the engine. For the car VAZ 2109 a resource of this belt is around 100 thousand km mileage. If the belt is worn or damaged, you should replace it before the deadline.
You will need
  • VAZ 2108-09, key 10, the key cap or head 19, the socket or head 17, a screwdriver, a portable lamp, a couple of bolts or nails 4 mm thick, in order to tension a new belt, a new timing belt.
Instruction
1
In order to remove the timing belt, you must remove all that can become a hindrance; it will provide maximum freedom for the withdrawal. Most likely, it will hinder the air filter, probably the steering power-steering pump and both pulleys V-belt.
2
Dismantling protection plastic timing belt is done by loosening the three mounting bolts.
3
After that, the crankshaft should be placed in the position of the upper dead point of the piston of the first cylinder. This is done by the slow rotation of a cranked shaft for a bolt to the pulley until mark on the pulley does not dock with the pointer on the rear cover camshaft actuator.
4
After fixation of the shaft with a screwdriver from turning, Unscrew the fixing bolt of crankshaft pulley.
5
Before removing the old belt it is worth noting the direction of his movement and only then loosen and remove. With a weakened belt pulley to rotate the crankshaft not.
6
Disconnect the pulley from the crankshaft.
7
To loosen the belt tension, you need not fully remove the nuts that secure the idler pulley and it rotated.
8
Now the timing belt can be removed.
9
If there is a need with the belt removed, rotate the camshaft, you need to ensure that at TDC, none of the pistons are not located. Otherwise damage the shaft and pistons.
10
Now you can gear on the crankshaft pulley to put the new belt on.
11
On the crankshaft pulley leading the belt is tensioned so that it does not SAG. The label on the back cover and the pulley should be the same.
12
Then the belt is put on the tension roller and a cogwheel of the water pump.
13
Putting the crankshaft pulley, the bolt that it is attached, is clamped 99-110 torque N•m (9,9-11,0 kgf•m).
14
Expanding according to the roller, pull the strap and tighten the nut which it is attached. In the absence of a special wrench to tension the belt, you can use two metal shaft, bolts or nails. They are inserted into holes of the roller between them is assigned with a screwdriver, with which the roller rotates, thus pulling the belt.
15
If the belt is tensioned correctly, it can rotate 90° with two fingers. Scrolling the crankshaft two turns, you need more time to check the tension and convergence of all labels. If necessary, adjustments.

Advice 2: How to change the timing belt for VAZ 2110

VAZ 2110 went off the Assembly line with 16-valve and 8-valve engines. The first is more powerful, faster, but quite expensive to maintain. Yes, and replace the timing belt on them is a little harder than on the 8 valve as the engine two camshafts.
For VAZ 2110 engines are installed with a different capacity and with different types of distribution systems. The most simple instances is a vosmiklapanny engine having per cylinder two valves (intake and exhaust). But the 16-valve, more powerful, has 4 valves per cylinder. Of course, there are two camshafts, so the engine design does not allow for the drive from one. It follows that the crankshaft must rotate two shafts instead of one. And the timing belt needs to be longer.

Replacing the timing belt on 8 valve engine



The procedure takes a small period of time, unless you know what you are doing. You need to know a little, the main thing – how to put markers on trees. Remove the first cover, which is covered by the timing belt, then loosen and remove the alternator belt. After you raise your right side of the machine, remove the wheel and protect him.

Now, when you removed the alternator belt and have access to the crankshaft pulley, you must put the shafts on labels. Rotate the crankshaft clockwise, align the marks you need:

• on the flywheel, it is made in the form of a line;
• on the camshaft with the strap installed on the engine.

With a screwdriver hold the flywheel from turning, remove the bolt of fastening of a pulley of the generator. Be careful not to damage the teeth, which are necessary for the operation of the engine speed sender. This applies to fuel injected motors. Otherwise, the ECU will generate an error.

Loosen tensioner pulley and remove it. Underneath is the adjusting washer, don't lose her. Now you can easily remove the belt and install the new. Put the roller, nivlem (do not tighten) the nut. Throws the belt on the crankshaft pulley, with a little stretch install it on the camshaft pulley. Put through the roller and the pump, we tighten the roller. Check the label matching before installing the belt.

Install the belt on the 16-valve engine



Here is a little more complicated, but still can be replaced pretty quickly. First remove the protective cover that attaches to the engine with six bolts. Then raise the machine on a Jack and remove the wheel with protection. Put the car in neutral and the rear wheel set stops. With a screwdriver hold the crankshaft over the teeth of the crown. So it is better to break the bolt on the pulley. If you substitute an emphasis under the teeth on the pulley, it is possible to damage them. Eventually the ECU will work correctly.

The removal procedure is the same as in the case of the 8-valve engine. Just keep in mind that 16-valve, not one, but two videos. Stretch (with two holes for special wrench) installed from the side of the cabin. A reference from the generator should be placed, there are no holes spetsklyuch. Don't be lazy, check whether the labels on the shafts before putting the new belt. This will allow you to do everything efficiently, and the next 50-60 thousand miles you will not know the problems with the timing mechanism.
Note
To bend or twist the timing belt is not worth it. Dirt and oil significantly reduces the service life of the belt.
Useful advice
Checking and adjusting tension of timing belt should be carried out on the cooled down engine.
