5.5.3. Check of pressure of oil

Fig. 3.28. Placement of the sensor of pressure of oil

Remove pressure sensor installed near an oil filter (fig. 3.28).

Connect instead of the sensor the manometer with the scale graduated from 0 to 1000 Pas.

Launch the engine and wait until oil heats up to temperature about 90 °C. Measure oil pressure in the mode of idling and with a frequency of rotation of a bent shaft of 2000 min. — 1.

Pressure of oil has to make in the idling mode 60 Pas, and with a frequency of rotation of a bent shaft of 2000 min. — 1 — 300 Pa.

If the measured pressure does not correspond to the specified values, check operation of the reducing valve and oil pump.
