Hydraulic jacks of backlashes of valves of the engine of 1,6 l

 PERFORMANCE ORDER

    While the hydraulic jack of backlashes of valves is established in a head of cylinders, press it with the maximum force in a place where the camshaft contacts with the backlash jack. If the jack of backlashes is serviceable, it will move downwards with great difficulty.
    If by pressing the jack of backlashes easily moves downwards, it is faulty and is subject to replacement. Fill the hydraulic jack of backlashes of valves with engine oil, hold vertically and hand fingers compress it from two parties.

The basic malfunctions of hydraulic jacks of backlashes of valves, the reasons and elimination methods are resulted in the table.

Malfunction
The possible reasons
Elimination method
• Temporary noise at start of the cold engine The normal phenomenon Noise disappears after warming up of engine oil and achievement of normal pressure
• Continuous noise after the engine was not started within 48 hours Oil from chambers of hydraulic jacks of backlashes of valves has flowed out and air has got to them Noise will disappear through 15 mines of work of the engine when the cranked shaft of the engine will reach frequencies 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 backlashes of valves.

• Continuous noise after start-up of the engine and replacement of a head of cylinders There is not enough oil in oil channels of the engine
• Continuous noise after long start-up of the engine by a starter or a towage method Oil from chambers of hydraulic jacks of backlashes of valves has flowed out and air has got to them
• Continuous noise, after replacement of hydraulic jacks of backlashes of valves
• Continuous noise, on frequency of idling after movement on high speed Engine oil level too low or too high Check up engine oil level
Air considerable quantity is dissolved in oil after high frequency of rotation Check up system of giving of oil
Deterioration of properties of engine oil Check up quality of oil and, if necessary, replace it
• Noise proceeds more than 15 mines Low pressure in greasing system Check up quality of oil and, if necessary, replace it
Hydraulic jacks of backlashes of valves are faulty Remove a head of cylinders and, pressing hydraulic jacks of backlashes of valves, check up size of their compression
