THE GENERAL DATA

The general receptions of dismantling of a head of the block of cylinders are included in the given part of the head and other knots of the engine.

The 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. The big run of the engine not always is the precondition to repair and, on the contrary, small run does not guarantee absence of necessity under repair.

The raised expense of oil testifies to necessity to pay attention to a condition of piston rings, маслосъемных caps and directing valves. At decision-making on repair of the specified knots make sure of absence of a leak of oil. Compression measurement in engine cylinders can give the additional information on repair volumes.

Check up size of pressure of oil by means of a manometre established instead of the gauge of pressure of oil.

The gauge of pressure of oil is established in the top part of the block of cylinders about the generator.

For access improvement to the gauge of pressure of oil it is necessary to remove the generator.

The lowered size of pressure of oil testifies to deterioration of bearings or damage of the oil pump.
Capacity falling, non-uniform work of the engine, blows and the mechanical noise, the raised noise клапанного the mechanism and the high expense of fuel, as a rule, testifies to necessity of repair. Especially if all these troubles have arisen simultaneously.
