 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Remove an air purifier.
  3. Cock the parking brake, поддомкратьте a front of the car and establish it on props. Remove the right forward wheel.
  4. With chalk or paint mark the direction of rotation of a belt of a drive of auxiliary units. Having taken away to a natyazhitel by means of a cap key, weaken a belt and remove it from the engine.
  5. Remove the top section of a cover of a drive of GRM [1].
  6. Prop up the engine by means of the KM-6001 adaptation and establish aligning KM-909-V tool.
  7. Remove a natyazhitel of a belt of a drive of auxiliary units.
  1. Remove the right support of a suspension bracket of the power unit assembled with the arm.
  1. Having passed in a transmission dome the special KM-911 tool [2], block from a provorachivaniye 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 a drive of GRM [5].
  4. Take blocking flywheel the tool.
  5. Temporarily screw into place a bolt of a pulley of a cranked shaft and bring the engine into the provision VMT of the end of a step of compression of the piston of the first cylinder (see. Reduction of the piston of the first cylinder in the provision of the top dead point of a step of compression (VMT). Make sure of correctness of combination of adjusting labels [6].
  6. Check correctness of combination of an adjusting label of a cogwheel with reciprocal risky on a back cover of a drive of GRM [7] — in case of need turn a cranked shaft on one complete revolution.
  7. Take away a mobile segment of a natyazhitel before combination of openings [8] and fix it in this situation, having passed in openings a suitable core.
  8. Remove a gas-distributing belt.

Installation

 PERFORMANCE ORDER

  1. Make sure of correctness of combination of adjusting labels [6] and [7].
  2. Having begun with a cogwheel of a cranked shaft and moving counter-clockwise, establish a gas-distributing belt. Track, that the belt was tense on sites between the next wheels.
  3. Take from a natyazhitel a lock core [8] and weaken bolts of fastening of assembly of the water pump [9].
  4. By means of the special tool KM-421-A develop the pump clockwise, having chosen a weak point of a tape of a belt [10] — the mobile section of a natyazhitel should appear opposite to an emphasis [11]. Slightly tighten bolts of fastening of the pump.
  5. Turn a cranked shaft on two complete revolutions clockwise and achieve the correct combination of adjusting labels [6] and [7].
  6. Again release fixing bolts [9] and by means of the tool KM-421-A develop the water pump counter-clockwise [12] so that the index of a natyazhitel appeared opposite to V-shaped risks of a basic plate [13].
  7. Tighten bolts of fastening of the pump with demanded effort (8 Nanometers).
  8. Turn a cranked shaft on two complete revolutions clockwise, having brought the engine into the provision VMT 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 the special KM-911 tool, block a flywheel [2].
  10. Turn out a bolt of a pulley of a cranked shaft [3].
  11. Operating as it should be, the return to a dismantle order, establish on the places the removed components.
  12. Screw a bolt of a pulley of a cranked shaft and tighten it with demanded effort.
