Cam-shafts and regulators клапанного a backlash

  • Do not turn cam-shafts or do not start the engine (i.e. valves should not work) about a half an hour after have repeatedly established hydraulic regulators клапанного a backlash and cam-shafts. As time is required that valves have risen on a place, start of the engine during a half an hour after repeated installation can lead to wrong gearing between valves or between valves and the piston.
  • If air has got to a regulator клапанного a backlash, the valve can publish a tapping sound at inclusion of the engine after regulator installation клапанного a backlash. In that case start the engine on half an hour with a speed 2,000 – 3,000 turns in a minute and then air will be продут and knock will stop. If the sound постукивания not to stop, probably, a regulator клапанного a backlash the faulty. If it faulty, replace it. If a faulty regulator not probably to define on hearing among 16 regulators, spend 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 cam crest should not be on a checked regulator, and check up, whether there is a backlash between a cam and a regulator. If is, the regulator is faulty and should be replaced.

Diagnostics of noise of a regulator клапанных backlashes

Regulator noise клапанных backlashes can be caused air which has got to regulators клапанных of backlashes, in following cases:

  • The vehicle has staid about 24 hours and more.
  • Have replaced engine oil.
  • Have replaced or have repeatedly established a hydraulic regulator of a backlash.
  • Engine major repairs.

If you suspect that noise goes from regulators клапанных backlashes, spend the following check.

 PERFORMANCE ORDER

  1. Check up engine oil.
    • Oil level in маслосборнике
  2. If oil level low, add oil to a mark of full refuelling on oil щупе.
    • Quality of oil
  3. If colour of oil has changed or quality of oil has worsened, replace it. Address to Section the Engine in the Head Maintenance service and greasing to receive recommendations about use of certain type of oil.
    • Oil leaks
  4. If leak is found out, eliminate it.
  5. If pressure does not correspond to norm, lead to its norm.
  6. Include the engine on half an hour with a speed 2000 – 3000 turns in a minute, and then air will be blown, and the sound постукивания to stop.
  7. If постукивание has not stopped, probably, hydraulic regulator клапанного a backlash is faulty. If it is not serviceable, replace it. If a faulty regulator not probably to define on knock among 16 regulators, check up 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 cam crest should not be on a checked regulator, and check up, whether there is a backlash between a cam and a regulator. If is, the regulator is faulty and should be replaced.
