3.5.3. Check of pressure of compression

GENERAL INFORMATION

Check of a condition of the engine can be made by measurement of pressure of compression in cylinders. If this check to make regularly, it is possible to learn in advance the beginning of wear of the engine, without waiting the moment when wear will be shown in low overall performance of the engine.

PERFORMANCE ORDER
1. Using компрессометр with an adapter, check pressure of compression in engine cylinders.
2. Before check of pressure of compression check, that the accumulator was charged and in a good condition. The air filter should be pure, and the engine should be heated-up to normal working temperature. Before check unscrew glow plugs. For prevention of start of the engine at carrying out check disconnect the electric socket from the control unit the fuel pump of a high pressure.
3. Establish an adapter with kompressometry in an opening for installation of candles of an incandescence.
4. Turn the engine a starter. After a provorachivaniye of a cranked shaft pressure of compression should increase by 1 or 2 turns to a maximum and then be stabilized. Make record of most received result. Similarly check other cylinders.
5. Pressure of compression in all cylinders should not differ more than on two units. Pay attention that the size of compression should increase quickly on the serviceable engine. Low pressure of compression on the first turn of the cranked shaft, accompanied by gradual increase in pressure on the subsequent turns, indicates wear of piston rings. The low size of pressure on the first turn of a cranked shaft which slightly increases further, indicates a thinness of a prileganiye of the valves, the punched laying of a head of the block of cylinders or existence of cracks in a head of the block of cylinders.
6. After carrying out check of pressure of compression connect the electric socket to the control unit the fuel pump and establish glow plugs.
