Do-it-yourself valve adjustment on a VAZ 2109

Many car owners of the VAZ 2109 are used to asking for help at a car service, even with such a rather simple operation as adjusting the thermal clearances of the valves. In fact, this work is not so difficult and you can do it yourself. To do this, you just need to have the following set of tools and devices, the list of which is given below:

1. Key 10 for removing the valve cover and timing belt cover
2. Jack
3. Long nose pliers or tweezers
4. Device for adjusting valves VAZ 2108-09
5. Flat and Phillips screwdrivers
6. Required shims
7. Probe set

The procedure for adjusting the thermal clearances of valves on the VAZ 2109-21099

Attention! The car engine must be cold and its temperature at the time of adjustment must not be higher than 20 degrees.

Video tutorial on how to get the job done

To clearly demonstrate the procedure for adjusting the thermal gaps, it was decided to record a special video clip that shows everything in detail.

If something remains incomprehensible from the guide presented above, then everything below will be set out in the form familiar to everyone.

So, before proceeding with this operation, you first need to remove the valve cover, as well as the casing under which the timing mechanism is located.

After that, it is necessary to set the gas distribution mechanism according to the marks. To do this, we jack up the front right side of the car so that you can turn the wheel with your hand to set the camshaft timing marks.

Then we turn the wheel until the mark on the camshaft star and the risks on the rear timing cover are aligned, as clearly shown in the picture below:

At the same time, we make sure that the mark on the flywheel also coincides with the cutout. You need to look through the window, which is located to the right of the fourth cylinder on the gearbox housing. You must first remove the rubber plug:

When the camshaft is in this position, you can start measuring the thermal clearances between the cams and pushers of the 1st, 2nd, 3rd and 5th valves (counting from the left):

For intake valves, the nominal clearance should be 0,20 (+ -0,05) mm, and for exhaust valves 0,35 (+ -0,05) mm. If you do not know the location, then I can say: from left to right in order: exhaust-inlet, inlet-outlet, etc.

If, when measuring the gaps, they go beyond the maximum permissible values, it is necessary to adjust them by installing new shims. To do this, we put the bar on the pins of the valve cover and fix it with nuts.

Now we bring the lever of the mechanism to the desired valve, and direct it, as it were, between the pusher and the cam of the camshaft, and sink the valve to the very end:

And when the pusher is pressed down as much as possible, it is necessary to insert a retainer between the camshaft and the pusher:

It is worth noting that the cutout on the pusher should be facing towards you so that you can conveniently remove the adjusting washer. It is very convenient to use long-nose pliers for this:

After that, we look at its size, which is indicated on its back side:

Now we calculate, based on the measured gap and the thickness of the old washer, how thick the new washer should be in order to achieve the optimal gap.

Now you can insert the new washer in its place and carry out the adjustment further. When the first 4 valves are ready, you can turn the crankshaft one revolution and carry out the same procedure with the remaining 4, 6, 7 and 8 valves.
