2.1.11. 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.

The main malfunctions of hydraulic jacks of gaps of valves, the reasons and methods of elimination are given in the table.

Malfunction	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 within 48 hours.	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 Prevention 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 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 gaps of valves flowed out and air got to them
Continuous noise, after replacement of 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	Check level of engine oil
	A large amount of air is dissolved in oil after high frequency of rotation	Check system of supply of oil
	Deterioration of properties of engine oil	Check quality of oil and, if necessary, replace it
Noise proceeds more than 15 mines	Low pressure in greasing system	Check pressure in greasing system
Noise proceeds more than 15 mines	Hydraulic jacks of gaps of valves are faulty	Remove a head of cylinders and, pressing hydraulic jacks of gaps of valves, check size of their compression
