4.2. General information
The general receptions of dismantling of a head of the block of cylinders are included in this section and other knots of the engine.
Information concerns sequence of preparation for repair and the step-by-step description of operations of removal and installation of components of the engine and their check.
It is not always easy to define, as where in the engine demands repair: too many factors should be taken into consideration. Big run of the engine not always is the precondition to repair and on the contrary, small run does not guarantee lack of need under repair.
The raised consumption of oil testifies to need to pay attention to a condition of piston rings, maslosjy ny caps and directing valves. At making decision on repair of the specified knots certify in lack of a leak of oil. Compression measurement in engine cylinders can give additional information on volumes of repair.
Check size of pressure of oil by means of a manometer established instead of the sensor of pressure of oil. The lowered size of pressure of oil testifies to wear of bearings or damage of the oil pump.
Capacity falling, non-uniform operation of the engine, blows and the mechanical noise, the increased noise of the klapanny mechanism and high fuel consumption, as a rule, testifies to need of repair, especially, if all these troubles arose at the same time.
