Cam-shafts and regulators of a klapanny gap

  • Do not turn cam-shafts or do not start the engine (i.e. valves should not work) about half an hour after repeatedly established hydraulic regulators of a klapanny gap and cam-shafts. As time is required in order that valves rose into place, engine start within half an hour after repeated installation can lead to the wrong gearing between valves or between valves and the piston.
  • If air got to a regulator of a klapanny gap, the valve can publish a tapping sound at turning on of the engine after installation of a regulator of a klapanny gap. In that case start the engine on half an hour with a speed 2,000 – 3,000 revolutions per minute, and then air will be blown and knock will stop. If the sound of a postukivaniye not to stop, probably, a regulator of a klapanny gap the faulty. If it faulty, replace it. If it is not possible to define a faulty regulator aurally among 16 regulators, carry out the following check.
    • About становите the engine also uncover cylinder heads.
    • Press a regulator a hand (having made effort less than 20 kg or 44 pounds), thus the crest of a cam should not be on a checked regulator, and check, whether there is a gap between a cam and a regulator. If is, the regulator is faulty and should be replaced.

Diagnostics of noise of a regulator of klapanny gaps

Noise of a regulator of klapanny gaps can be caused by the air which has got to regulators of klapanny gaps, in the following cases:

  • The vehicle staid about 24 hours and more.
  • Replaced engine oil.
  • Replaced or repeatedly established a hydraulic regulator of a gap.
  • Major maintenance of the engine.

If you suspect that noise goes from regulators of klapanny gaps, carry out the following check.

 PERFORMANCE ORDER

  1. Check engine oil.
    • Oil level in an oil pan
  2. If oil level low, add oil to a mark of complete filling on oil щупе.
    • Quality of oil
  3. If color of oil changed or quality of oil worsened, replace it. Address to the Section Engine in Head Maintenance and greasing to receive recommendations about use of a certain type of oil.
    • Oil leaks
  4. If leak is found, eliminate it.
  5. If pressure does not correspond to norm, lead it to norm.
  6. Turn on the engine on half an hour with speed of 2000-3000 revolutions per minute, and then air will be blown, and the sound of a postukivaniye to stop.
  7. If the postukivaniye did not stop, probably, the hydraulic regulator of a klapanny gap is faulty. If it is not serviceable, replace it. If it is not possible to determine a faulty regulator by knock among 16 regulators, check the following.
    1. Stop the engine and uncover cylinder heads.
    2. Press a regulator a hand (with effort less than 20 kg or 44 pounds), thus the crest of a cam should not be on a checked regulator, and check, whether there is a gap between a cam and a regulator. If is, the regulator is faulty and should be replaced.

  2. Remove cam-shafts.
  3. Remove regulators of a klapanny gap (2).
  • Never assort a hydraulic regulator of a klapanny gap.
  • Do not press on the regulator case, the oil being in the chamber under a high pressure, will follow.
  • Lower the taken-out regulator in pure engine oil (1) and store it there until will establish it repeatedly to prevent leakage of oil. If you leave it on air, put it in its kovsheobrazny case the face down. Do not put it sideways or in the kovsheobrazny case the face up.

And — do not apply force.

Check

Wear of a cam

With the help a micromeasure measure cam height. If the measured height is lower than norm, replace a cam-shaft.
