Adjustment of VAZ 2106 valves by one's own hands

All motorists know that in every car between the valves there is a small gap. Often this value is 0.15 millimeters. This clearance is made so that during operation of the engine the mechanisms do not jam between themselves due to heating. As we know, the working temperature of the motor is 85 degrees Celsius. It is not difficult to imagine what difference between the gaps will be formed if the machine is cooled at minus 20 degrees, and what will happen when the engine reaches its operating temperature. If this slot is too small, the car will immediately lose its power, and in the cabin, there will be extraneous sounds from under the hood in the form of knocking and "shots". To avoid such trouble, it is necessary to observe the periodicity and order of valve adjustment. VAZ 2106 today will be our "guinea pig". On his example, we will consider how to make the adjustment of valves on all engines of the "classics" (VAZ 2104-2107).

Determine the distance between parts

First, you need to determine the exact gap between the valves. To adjust the valves VAZ 2106 was successful, we remove the lid of the unit and install the piston 4 cylinder in the TDC - the top dead center. Thus, the 6 and 8 valves will be closed, respectively, the gap between the push arms and the cam will be maximum. Then insert the probe into the gap and make sure that it passes smoothly between the valves with moderate force. If you feel that this part is stuck in the gap, the adjustment of the VAZ 2106 valves is mandatory. And it is made as follows:

1. Using a carabiner wrench, loosen the lock nut and the second one turn the adjusting bolt.
2. First, the optimal clearance between the third and fourth valve should be set. Then turn the crankshaft by 180 °. After that, the adjustment of the VAZ 2106 valves is accompanied by an optimal clearance between the second and the fourth gear. Then again crank the crankshaft. We adjust the third and the first valve. After this, we proceed to set the gaps between the sixth and the eighth, the fourth and the seventh, the first and third, the fifth and the second mechanism. It should be noted that each adjustment of the VAZ 2106 valves is accompanied by a 180 degree turn of the crankshaft. That is, after each pair of mechanisms, this shaft rotates. To be more convenient to consider the amount of rotation, track it by the value of the ignition distributor. Previously, you need to remove the cover from it. Before each turn, mark the position of the slider and repeat this process. It is important to ensure that the value of our "indicator" does not exceed ¼ of the turnover. Then you will definitely be sure that the crankshaft rotated 180 degrees.

Conclusion

As you can see, repairing the VAZ 2106 with your own hands is not so difficult. You just need to carefully monitor the frequency of the stages, do not forget to scroll the crankshaft to a certain value and in time to note the values of the runner.
