18.104.22.168. Check of pressure of oil
The hot engine and oil can become the reason of serious burns. Before check stop the engine and wait, so far the engine and engine oil will not cool down.
Remove the lower protective cover of the engine.
Remove the oil pressure sensor.
Fig. 2.200. Installation of special device for measurement of pressure of oil
Screw special adaptation in an opening of the sensor of pressure of oil (fig. 2.200).
Warm up the engine up to the normal working temperature.
Establish the specified turns of the engine and write down instrument readings.
If pressure differs from specified, find out the reason and repair or replace if necessary the damaged details.
Pressure of oil depends on viscosity and temperature.
Oil temperature – 100 °C:
L8, LF: 234–521 kPa (2,39–5,31 kgfs/cm2 at 3000 min.-1);
L3: 395–649 kPa
(4,03–6,61 kgfs/cm2 at 3000 min.-1).
Stop the engine and let's it cool down.
Remove special adaptation.
Hit of sealing material on a working part of the sensor of pressure of oil can lead to a sensor conclusion out of operation. Make sure that on a working part of the sensor of pressure of oil there is no sealing material.
Fig. 2.201. The place of putting sealant on an oil pressure sensor carving
Apply kremniyevoorganichesky sealant on an oil pressure sensor carving, as shown in the figure 2.201.
Install the oil pressure sensor.
Inhaling moment: 12–18 N · m.
Establish a protective cover of the engine.
Start the engine and check lack of leak of oil. In the presence of leak define a defective part, repair or replace it.
