5.4.6. Relay of pressure of oil

GENERAL INFORMATION

The relay of pressure of oil is established on a crossing point of the block of cylinders of the engine. The relay of pressure is connected in parallel to the relay of the fuel pump and duplicates a pump food at achievement of pressure in system of greasing of the engine of 28 kPas. The relay of pressure is the spare switch of the fuel pump. The unique operation of servicing of the relay of pressure is check of a condition of electric contacts. At failure of the relay it is replaced assembled.
