How to adjust the valve at UAZ</a>

Every car enthusiast wants to have a serviceable car so that you can not worry about traveling.

A large role in this is played by correct access toEngine fuel and exhaust gas. "Sneezing" or "shots" in the muffler - all this can occur from the wrong installation of the valve clearance of the gas distribution mechanism.

Repair in this case will not be a big deal, the main thing is to correctly set the TDC (top dead center) and observe the order when adjusting.

You will need

  • - probe 0,3 ... 0,35-
  • - screwdriver-
  • - a set of keys.



Examine the cap of the trambler, find the wire,Which goes to the candle of the first cylinder (closest to the radiator). Remove the cover of the trambler and remember the place where the slider should be located, so that the spark goes to the candle of the cylinder 1. Look at the top of the trambler - the position should be "10h". Remove the valve cover, detach all attached components from it.


Inspect the crankshaft pulley. It must have 2 or 3 risks. Align the third (second), i.e. The last one on the right in the direction of rotation is the risk with the guide on the cylinder block (the pulley rotates clockwise). Insert the "starter curve" and align the specified risk with the guide. If it is not possible to apply it, then turn the shaft by hand - for pulleys and belts, insert a screwdriver into the crown nut and rotate it using a suitable wrench.


Look at the slider of the trambler after combiningRisks. When it is located in the right place (point 1), then the piston of the 1st cylinder is in the TDC. The valves are closed at this moment, so you can adjust them. Press the rocker, there will be a gap. In other cases, adjust the valves of the 4th cylinder.


Set a clearance of 0.35 mm on the dipstick. Please note that the probe should come in with a slight but noticeable effort. Insert it into the gap between the valve and the rocker arm. Loosen the lock nut, turn the adjusting bolt to the left or right, depending on the need to increase or decrease the clearance. The clearance 0.35 should be placed on all valves of all cylinders. If the air temperature is from -5 to 0 degrees, then make it 0.4 mm.


Turn the crankshaft 180 degrees afterAdjust the clearance on the 1st cylinder and produce the same with the second. Determine the rotation either on the slider of the toggle or on the notch on the pulley. After that, rotate it another 180 degrees and adjust the 4th cylinder, then again 180 degrees and the third. The operation of the cylinders of engines 417 and 421 is as follows: 1-2-4-3. Place the valve cover, attach attachments to it.
