The adjustment of the gaps of the auto engine valves is rather important, but at the same time, a simple procedure that will allow you to save your funds, as it costs a lot to a hundred. Self adjustment of the valves will help you customize the motor in such a way that it will always work like a clock.

Adjusting the engine valves, and why regulate the valve

When adjusting the valves, it is necessary to know that one cylinder has two or more valves. In the valve mechanism it is necessary to adjust the gaps that arise between metal elements as a result of heating. Before you start adjusting the valves, you must completely cool the engine, checking the gaps with a flat probe.

Self adjustment of the valves is necessary due to the fact that during heating, the gaps between the metal elements of the valve mechanism or decrease, or expand. In this case, the motor will not be able to work normally and start to knock, its capacity will fall significantly, the carburetor will "sneeze" and so on.

In addition, the wrong and bad adjustment can lead to more serious consequences. For example, the efficiency of the motor operation will decrease even more, as a result of which premature wear of the elements may occur. If the gaps will be too small, the valves and their saddles can burn. With large gaps, you can see the knock of metal elements and other signs.

Thermal gaps of valves, how to find out the size of the thermal gap of your own car

Data on the sizes of heat gaps can be found in the manual for the vehicle or in other sources, for example, on the Internet.

It is necessary to know that in a variety of types of cylinders, typical gaps for the graduation or inlet valve may differ significantly. And if you do not know this, you can make a serious mistake when adjusting with your own hands.

Adjusting gaps, how often the adjustment of the gaps

Valve checks must be carried out every 20-30 tons. Kilometers.

The passage of this kilometer does not indicate that it is necessary to adjust the valve gaps. Many manufacturers are used on vehicles Modern systems that do not require the implementation of such a procedure.

Probe gaps, what is it and what information is on this instrument

As already mentioned above, during adjustment, the vehicle motor should be cold. The gaps must be checked by a special flat probe optimal thickness. There are specialized tv rings, which must be adjusted. Some VAZ models are tuning using a special adjusting bolt head.

Adjusting valve gaps, step-by-step instructions

In this process, the Motor Valve Adjustment mode is important. First of all, it is necessary to unscrew the bond cover mounting nuts, and then remove it. Do not forget to remove the protective cover of the toothed belt.

To begin with, remove the ignition candles. Next, remove the oil in the head of special baths. Then carefully inspect the surface of the cams - for the presence of scratches, shells or other wear.

A tag on the pulley align with the installation protrusion, which is located on the rear protective lid. To obtain the desired result, rotate the crankshaft in a clockwise direction, while holding the bolt that crept the generator drive pulley.

This position corresponds to the upper point of the required cylinders. Otherwise, end the crankshaft at fifty percent (2-3 teeth). After that, it is necessary to check the clearances from the third and first cams. It is desirable that the probe would not be prominent and not too loose, with a slight pinch. Otherwise, replace the washer.

Then you need to turn the crankshaft to the floor of turning forward.

Now check the gaps of the second and fifth cams. To check the cam 8 \\ 6, check the crankshaft on the half of the turnover, also for checking 4 \\ 6 cams.

After adjusting the valves, start the motor to check the efficiency of the operation. However, it is necessary to listen to the motor in different modes of operation.

Measuring the gaps of the diploma, detailed instructions, advice of professionals

The adjustment of the valve gaps must be carried out after mounting the cylinder into the upper dead point. In addition, both valves of this cylinder must be closed, but the rocker can move freely.

During the setup process, you need to release a lock nut, which is located on the bolt or adjusting screw. After adjusting the desired gap, we tighten the knockedy dipstick. Be extremely attentive, because the configured clearance after the wrong tightening may change. Therefore, you should check the gap again after the tightening. If the probe passes tight or too easy, adjust the gap more precisely.

Now it is necessary to align the gaps of other cylinders, turning half the crankshaft. It should be remembered that the crankshaft can be turned only clockwise, while holding the starter lever - the starter curve.

Adjusting thermal gaps, how to adjust the gaps using the rail with the indicator

The results of the procedure will be much more efficient if used is not a simple probe, but a special fixture - a rack with an indicator.

The method of carrying out such an operation is actually the same as probe. However, there are some differences. Do not forget to check the gap after the setup.
