3.4. Major maintenance of the engine
It is not always easy to come to a conclusion about expediency of complete major maintenance of the engine as it is necessary to be based on a number of objective indicators.
Big run is not a sufficient indicator of need of carrying out major maintenance, on the other hand, small run does not exclude need of carrying out major maintenance.
The raised consumption of oil indicates wear of the piston rings, directing plugs of valves and maslosjemny caps. It is necessary to be convinced that leaks are not at the bottom of the raised consumption of oil, and only after that to draw a conclusion about unfitness of piston rings and directing plugs of valves. To define a probable cause of malfunction, measure a compression in engine cylinders.
For scoping of the forthcoming works check a compression in engine cylinders. Carry out also tests by means of the vacuum gage and define character of indications of this device.
Check pressure of oil a manometer screwed to the place of the sensor of pressure of oil and compare result of check to standard value. If pressure of oil low, the reason can be wear of radical and shatunny bearings or details of the oil pump.
Capacity loss, "failures" in operation of the engine, a detonation or the metal knocks, the increased noise from the gas-distributing mechanism, indicate the increased fuel consumption need of carrying out major maintenance, especially, if all these signs of abnormal work are shown at the same time. If performance of all adjustments does not lead to improvement, the unique means of elimination of abnormal operation of the engine is major maintenance.
Before the beginning of major maintenance of the engine familiarize with the description of the corresponding procedures that there was an impression of the forthcoming amount of works and requirements to them.
At observance of all norms and rules, in the presence of all necessary tools and adaptations, it is simply to execute major maintenance, considerable expenses of time however be required. Roughly not less than two weeks, especially are required if for repair and restoration of details it is necessary to address in a specialized workshop.
Check existence of spare parts and in advance take care of acquisition of necessary special tools and the equipment.
As the condition of the block of cylinders is defining factor of decision-making on its further repair or about purchase new (or repair) the block of cylinders, to buy spare parts or to carry out operations on machining of accompanying details follows only after careful check of its technical condition. Make it a rule that the true price of repair is time, – then it is not necessary to pay for installation of the worn-out or restored details.
In summary we will note that assembly of any units should be carried out with all care in a pure room to avoid further failures of the repaired engine and to provide its reliable work.
