THE GENERAL DATA

The manometre used for check of pressure of engine oil and working capacity of the gauge of pressure of oil

And – the gauge of pressure of oil,
3 – a wire of grounding of a manometre

If at engine work the control lamp of pressure of oil lights up and the sound signal is distributed, it can be caused following reasons:

– Level of oil below norm;
– Malfunction presence in an electric chain of the gauge of pressure and a control lamp;
– Unsatisfactory work of the oil pump;
– Too big backlash in bearings of a cranked shaft.
At fire of a control bulb of pressure of oil on the working engine immediately switch off the engine. Using щуп for measurement of level of engine oil, check up level of oil and if necessary, finish it to norm. Start the engine on turns of idling and check up that the control lamp of pressure of oil any more does not burn. In this case it is possible to continue movement.

If engine oil level in norm, and a control bulb of pressure of oil burns, do not continue movement independently, and tow off the car in a workshop for check of pressure of oil.

If pressure of oil in norm, check up the gauge of pressure of oil and электричес I forge a gauge chain.

For check of pressure of oil and the gauge of pressure of oil it is necessary to use a special manometre in which it is possible to screw in the gauge of pressure of oil.

Check

PERFORMANCE ORDER

1. Check up level of engine oil and, if necessary, finish it to norm.

2. Warm up the engine to normal working temperature.

3. Unscrew from the holder of the oil filter the gauge of pressure of oil and screw in it in a manometre, fig. a Manometer used for check of pressure of engine oil and working capacity of the gauge of pressure of oil see.

4. Screw in an adapter of a manometre instead of the gauge of pressure of oil in the holder of the oil filter.

5. Connect to weight of the car a wire of grounding of a manometre.

6. Using additional wires, connect a control light-emitting diode with the positive plug of the accumulator and contact of the gauge of pressure of oil. The light-emitting diode should burn.

7. Start the engine and smoothly increase engine turns. At superfluous pressure in petrol engines 1,2–1,6 bar and 0,75–1,05 bar for diesel engines, the light-emitting diode should go out. Otherwise the gauge of pressure of oil is faulty.

8. Increase turns of the engine to 2 000 rpm. At temperature of oil 80 About superfluous pressure of oil should be not less than 2,0 bar. Smaller pressure of oil specifies in deterioration of bearings of a cranked shaft.

9. Continue the further increase in turns of the engine. Thus pressure of oil should not exceed 7,0 bar. Otherwise has failed перепускной the valve and it is necessary to replace a cover of the oil pump with перепускным the valve.

10. Establish into place the gauge of pressure of oil with a new sealing ring and tighten its moment of 25 Nanometers.
