A worn timing chain is one of the most serious troubles that can happen to a car. Fortunately, this part serves for a very long time, but when it's time to replace, many car enthusiasts are wondering how the timing chain is being installed (VAZ-2106 including). And today we will consider this point in more detail.

Instruments

In order to replace the timing chain VAZ 2106-th model was successful, we need to prepare the following set of tools:

• Universal pulley lock.
• The key is 36 millimeters.
• A screwdriver or a spanner.

Having prepared this set of tools, you can safely get down to work. Help us partner, we also do not hurt.

Self-replacement

During the work we need to partially disassemble the internal combustion engine. For convenience of carrying out all actions, it is recommended to dismantle the hood so that it does not interfere with the work. Before removing the element, the timing marks are installed. VAZ-2106 ("six") when installing tags will no longer need a long and painful adjustment. Ideally, the crankshaft key should be in front of the tide on the cylinder block - this is how the tags should be exposed.

After that, the wings are covered with a piece of dense rags (the usual blanket will do). Doing this is not necessary, but this will protect the body from possible deformations and scratches. How is the timing chain replaced (VAZ 2106) next? We take out the cooling radiator and remove the belt from the pulley. Then you must turn on the first gear and press the brake pedal. At the same time, the helper must unscrew the nut on the pulley. This is done with a large screwdriver or a balloon wrench. As a result, the pulley must come off the crankshaft.

In the next step, remove the valve cover. To do this, you must first remove the air filter, the accelerator pedal, and the suction cable from the carburetor. Then unscrew all the nuts and take out the valve cover. Then remove the front cover of the engine. To do this, unscrew the nuts and screws. Remember that 3 bolts serve to lock the lid to the crankcase. If the lid comes off with difficulties, you can use a minus screwdriver. However, be careful, as with inaccurate handling, the lid can simply crack.

To dismantle the chain of the gas distributor, it must first be loosened. To do this, the tensioner is lowered. Further, the lock washers are bent and the bolts securing the timing chain sprocket are loosened. After we remove two gears. But the dismantling of the chain does not end there. In order to finally take it out, twist a special restrictive finger. All, now the element can be safely removed from the engine compartment.

It is also recommended to diagnose the serviceability of the tensioner shoe. To do this, remove it and look at the external state. If it is badly worn and worn, it is recommended to replace it with a new one immediately.

Then loosen the tensioner and put a new chain. Be sure to look at the state of the first element. Check the tightness of the tensioner is very simple. To do this, release the outer nut and press the rod in such a way that it goes inside. Then the nut is tightened. Under the action of the spring, the rod must come out. If this does not happen, then the tensioner has become unusable and needs to be replaced.

After changing the timing chain caliper. In the case of heavy wear, this element can burst, and parts of it will fall down the ICE. It is fastened by 2 cogs to the cylinder head. We unscrew them with a screwdriver and install a new element. By the way, when buying a new chain, you need to pay attention to the dimensions of the element. To not get too long or short, you need to know in advance the model of ICE. On it also it is necessary to select a new chain.

When is the timing chain needed?

VAZ-2106, in spite of its reliability parameters, very rarely needs to replace this element. As practice shows, the chain changes every 100-200 thousand kilometers, depending on how the car is operated.
