  3. Cock a lay brake, поддомкратьте redock of the car and establish it on props. Remove the right forward wheel.
  4. With chalk or paint mark a direction of rotation of a belt of a drive of auxiliary units. Having taken away натяжитель with the help накидного a key, ослабьте a belt also remove it from the engine.
  5. Remove the top section of a cover of drive ГРМ [1].
  6. Prop up the engine by means of adaptation KM-6001 and establish aligning tool KM-909-V.
  7. Remove натяжитель a belt of a drive of auxiliary units.

  1. Having passed in a transmission dome special tool KM-911 [2], block from проворачивания a flywheel.
  2. Turn out a fixing bolt [3] and remove a pulley of a cranked shaft [4].
  3. Remove the bottom section of a cover of drive ГРМ [5].
  4. Take blocking flywheel the tool.
  5. Temporarily screw into place a bolt of a pulley of a cranked shaft and result the engine in position ВМТ of the end of a step of compression of the piston of the first cylinder (Reduction of the piston of the first cylinder in position of the top dead point of a step of compression (ВМТ) see. Make sure of correctness of combination of adjusting labels [6].
  6. Check up correctness of combination of an adjusting label of a cogwheel with reciprocal риской on a back cover of drive ГРМ [7], — in case of need turn a cranked shaft on one complete revolution.

  7. Tighten bolts of fastening of the pump with demanded effort (8 Nanometers).
  8. Turn a cranked shaft on two complete revolutions clockwise, having resulted the engine in position ВМТ of the end of a step of compression of the piston of the first cylinder, — make sure of correctness of combination of adjusting labels [6] and [7]. If demanded combination of labels does not occur, repeat procedure of adjustment of a tension of a belt.
  9. Having passed in a transmission dome special tool KM-911, block a flywheel [2].
  10. Turn out a bolt of a pulley of a cranked shaft [3].
