Check

 PERFORMANCE ORDER

  1. Warm up the engine to working temperature ОЖ and be passed on the car of 5 more km to reach temperatures of impellent oil not less than +80 hailstones.
  2. At a corresponding complete set switch off К/В.

Steer clear of moving parts of the power unit not to be traumatised.

The ignition moment is established correctly if the label on a pulley in relation to a label on the bottom cover of a gear belt seems motionless. Thus the ignition moment corresponds 10 hailstones. To ВМТ the Number of turns of a cranked shaft at check should make 700 1000 rpm.

Labels for check of the moment of ignition

If labels of installation of the moment of ignition do not coincide, it is necessary to spend its adjustment.
