How to pull the chain on the VAZ-2107. Voltage regulation of the circuit

To normally ride your car, you need to know how to pull the chain on the VAZ-2107. It is installed in the front side of the engine, immediately behind the cooling radiator. In the article, we will consider how to adjust and adjust the drive of the gas-distributing mechanism of the seven. You will learn about many of the nuances that will help with the operation of the car. They are extremely important, since the functioning of the valve system affects the quality of the ride.

When is it necessary to change the circuit?

The timing chain is located under the cover in the front of the engine. It does not matter which engine is installed in your car, all repair work must be carried out according to the scheme below, both on the injector and the carburetor engine. Chain replacement is necessary in cases when it is too much extended. In this case, the chain tensioner VAZ-2107 does not help to get rid of excessive sagging.

Also, it needs to be changed if there is a break in the process of work. First, the radiator grille is removed and all liquid is drained from the cooling system. After that, the nozzles from the radiator are disconnected, the electric fan is removed if necessary. The radiator housing is disconnected from the brackets and completely removed from the vehicle. Also, you need to remove some elements from the internal combustion engine to pull the VAZ-2107 chain.

Preparation for Chain Replacement

Loosen the nut on the generator, remove its belt. After that, unscrew all the nuts that attach the cover to the cylinder head. Note that the engine tray is screwed into the front cover that covers the timing chain with three bolts. These three bolts must be unscrewed. Establish a camshaft so that labels on the top asterisk coincided with a ledge on a cover of a camshaft. Produced this is the same with the key for the ratchet. Be sure to remove the chain tensioner VAZ-2107 so that it does not interfere with the disassembly.

Turn the crankshaft pulley only clockwise. Unbend all the petals that fix the lock washer. Then, unscrew the nut that secures the sprocket. But do not rush to shoot it. After loosening the fastening of the pulley, which is located on the crankshaft. Also, the nut is loosened, with which it is fastened. Disassembly is finished, nothing more will prevent you from removing the cover from the timing chain. Using the key for 10, it is necessary to unscrew all the bolts that secure the cover to the engine block. Before you pull the chain on the VAZ-2107, make sure that it is in good condition.

Disassembly and Replacement

With a small rubber hammer, gently tap the lid around the perimeter. Otherwise, it will be bad to fall behind the landing. After removing the cover, you must dispose of the old gasket. Please note that the remainder of it can remain on the engine. Put a mark on the drive sprocket of the trambler and oil pump, in order to not subsequently re-set the ignition timing. Only then you can dismantle the sprocket on the camshaft.

After doing this, you need to remove the tensioner, bending off the petals that are on the sprocket washer sprocket. With the help of it, a trampler with an oil pump is set in motion. Then it is necessary to unscrew the nut, then remove the timing chain. That's all, the chain is removed, and the installation of the new is in the reverse order. Further on how to pull the chain on the VAZ-2107 with your own hands. And do not forget that you need to fix all the screwed connections with the help of lock washers.

Preparing for tensioning the chain mechanism

To adjust the tension of the timing chain, you need to perform some operations. This is carried out in the case when the chain mechanism is very much extended, began to appear metallic ringing. Please note that it is also necessary to carry out the adjustment in cases where the chain was removed from the engine of the car during other repair work. For convenience, it is best to install an automatic chain tensioner VAZ-2107 of a special design. It will help get rid of the frequent control of the gas distribution mechanism.

Before adjusting the gaps in the valves, it is also necessary to adjust the tension of the chain. After replacing the tensioner or the soothing, the same manipulations are carried out. As a rule, the chain does not bounce constantly, but only with increasing the speed of the crankshaft. At this point, the ringing starts to appear, but it decreases when the engine is leveled. If the chain is too stretched, it will cause all phases of the gas distribution to gradually shift, which will lead to interruptions in the functioning of the internal combustion engine.

Conducting chain tension

Now I need to say a few words about how to pull the chain on the VAZ-2107. For adjustment, it is first necessary to fully de-energize the chain tensioner. To do this, unscrew the nut on the cap with a key of 13. At this point, the shoe should snap off. If this did not happen, then, most likely, there was a seizure of the plunger. Try to tap the hammer slightly to get rid of this problem. Turn the crankshaft several turns with a key of 38. It should stop at the moment when there is the greatest resistance for rotation.

Finish setup

In this position, the timing chain will be in an extended state. This is what is needed for proper adjustment. Hold the crankshaft so that it does not turn in the opposite direction. Then tighten the nut on the cap. And at the final stage it is necessary to put a cover on the cylinder head. On this stretch of the chain VAZ-2107 is completed, took the entire procedure is not so much time. The drive chain now has a normal tension.
