From the article you will learn how to tension the chain on the VAZ-2107 with your own hands. Although it seems that this is a terrible occupation, which is unlikely to be possible for an ordinary motorist, in practice everything is different. All work on setting up and adjusting the drive can be done pretty quickly yourself. And now let's try to understand the nuances of this procedure.
How to replace a damper
In the gas distribution system on a VAZ-2107 car, there is such a device as a chain damper. It serves to dampen chain vibrations during its rotation. If there is a metal knock coming from the drive side, then most likely this indicates that the tension is too weak or the damper has very strong wear. In the second case, a complete replacement of the damper will be required. It is located in front of the car engine. When replacing the VAZ-2107 circuit, it is advisable to put a new damper.
To replace it, you need to remove the cover from the cylinder head, and then fix the damper with a convenient tool, such as a screwdriver or key. Next, you need to unscrew the two bolts that secured the damper to the block body. The housing must be carefully removed. Installing a new one is carried out in the reverse order. Note that the top bolt is slightly larger. It is longer than the bottom. The VAZ-2107 circuit breaker has no more features.
Chain tensioner
It is installed on the right side of the internal combustion engine, next to the pump of the cooling system. The operation of the engine directly depends on how well its gas distribution mechanism functions . The chain tensioner is necessary in order to regulate the sagging of the drive mechanism. The greater the mileage of a metal chain, the more it stretches. For this reason, you need to know how to tension the chain on the VAZ-2107 in order to get rid of problems with it. Sagging increases, it is even possible to slip on the pulleys of the crankshaft and camshaft. Replacement is quite simple, you can install a new tensioner in a few minutes.
To do this, open the hood, use a socket wrench to 10 to unscrew both bolts that secure the tensioner to the engine, and then carefully remove it. Please note that there is a gasket for sealing. If it has fallen into disrepair, then you need to install a new one. After removing the case of the timing chain tensioner, hold it in a vice, then use a 13 wrench to unscrew the nut in the center. With this action you can check if the collet lock is working. If there is a breakdown of the cracker, then you need to replace the cap or tensioner assembly. And later, for work, you need to know how to tension the chain on the VAZ-2107.
Installing a new tensioner
When checking the timing chain tensioner , in particular if replacement is necessary, you need to start installing a new one. But do not forget that before starting installation, it is necessary to charge this mechanism. To do this, you will need to push the plunger mechanism all the way down, and then, holding it in this position, tighten the nut on the cap.
After that, it is necessary to install the tensioner housing and tighten the bolts. Do not forget that you need to put a new gasket if the old one is out of order. Using a special key with a size 38 for ratchet, turn the engine crankshaft at rpm. In this case, the timing chain is pulled. You need to make one revolution, then release the cap nut to discharge the tensioner. After that, it must be tightened again.
How to tension the chain
This procedure is not difficult, it is performed on cars of the classic series quite quickly. It must be carried out if the VAZ-2107 circuit was replaced or removed. To tighten the timing chain drive, you need to use the 13 key to unscrew the nut that is on the tensioner. But you do not need to twist it to the end, just loosen it. Rotate the crankshaft slowly with the ratchet wrench.
Watch how much effort you apply to the lever. When you feel that you need to make a lot of effort, stop and hold the key so that it does not turn. It is in this position that the chain is in tension, so it needs to be fixed. When the tensioner rod holds the chain tight, tighten the nut. That's all, the work is over. Here's how to pull the chain on the VAZ-2107, the procedure is elementary.
Conclusion
Now you have an idea of how to work with the timing chain. It is worth noting that everyone should know how to tighten the VAZ-2107 chain, because it is gradually stretched during car operation, the metal wears out. It is necessary to constantly monitor the state of the gas distribution mechanism. It also does not hurt to tighten just before starting to adjust the clearance in the valves.
