1.2.11. Hydraulic jacks of gaps of valves

Fill the hydraulic jack of gaps of valves with engine oil, hold vertically and fingers of a hand compress it from two parties.

Possible reasons

Elimination method
Temporary noise at start of the cold engine.
Normal phenomenon Noise disappears after warming up of engine oil and achievement of normal pressure
    Continuous noise after the engine was not started up within 48 hours.
    Continuous noise after start of the engine and replacement of a head of cylinders
  • Continuous noise after long start of the engine by a starter or a towage method
    Continuous noise after replacement of hydraulic jacks of gaps of valves
    Oil from chambers of hydraulic jacks of gaps of valves flowed out and air got to them There is not enough oil in oil channels of the engine Oil from chambers of hydraulic jacks of gaps of valves flowed out and air got to them

Noise will disappear through 15 mines of operation of the engine when the cranked shaft of the engine will reach frequency of rotation of 2000-3000 mines–1

Do not increase frequency of rotation of a cranked shaft of the engine above 3000 mines-1 as it is possible to damage hydraulic jacks of gaps of valves

Continuous noise on frequency of idling after movement on high speed
    Level of engine oil too low or too high A large amount of air is dissolved in oil after high frequency of rotation Deterioration of properties of engine oil
    Check level of engine oil Check system of supply of oil Check quality of oil and, if necessary, replace it
Noise proceeds more than 15 mines
    Low pressure in greasing system Hydraulic jacks of gaps of valves are faulty
    Check pressure in greasing system Remove a head of cylinders and, pressing hydraulic jacks of gaps of valves, check size of their compression
