For removal of a pulley of a cranked shaft it is necessary to use a stripper.


Combination of a label of VMT on a camshaft pulley with the index on a cover

Combination of a label of VMT on a pulley of a cranked shaft with the index on a back casing of a gear belt

Arrangement of bolts of fastening of a pulley of the cranked shaft, available through an arch of the right forward wheel

Arrangement of a bolt of fastening of a pulley of the mechanism of a tension of a gear belt

Removal of a hose of ventilation of a case from a cover of a head of the block of cylinders

Removal of the cover closing spark plugs

Unscrewing of a bolt of fastening of a head of the block of cylinders

Arrangement of continuous rubber laying of a cover of a head of the block of cylinders

Wrench use for camshaft keeping from a provorachivaniye


Pulleys of a gear belt
1–bolt of fastening of a pulley of the mechanism of a tension;

2–arm of a pulley of the mechanism of a tension;

3–bolt of fastening of an intermediate pulley


Arrangement of the top rack for the screw of fastening of an external casing of a gear belt (1) and the top bolts of fastening of a back casing (2)


Arrangement of the right bottom bolt of fastening of a back casing of a gear belt

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Disconnect a branch pipe of the air filter from a measuring instrument of a stream of air. Uncover the air filter and take filtering element. If necessary for improvement of access remove the case of the air filter.
3. Remove a belt of a drive of the pump of the amplifier of a steering.
4. Remove a belt of a drive of the generator.
5. Unscrew three screws and remove an external casing of a gear belt. Take rubber sealing rings from openings under screws in a casing.
6. For a bolt of fastening of a pulley of a cranked shaft turn a cranked shaft of the engine in the direction of working rotation before combination of adjusting labels on pulleys with indexes (see fig. Combination of a label of VMT on a camshaft pulley with the index on a cover, Combination of a label of VMT on a pulley of a cranked shaft with the index on a back casing of a gear belt).
7. Unscrew 6 bolts and remove a pulley of a cranked shaft (see fig. An arrangement of bolts of fastening of a pulley of the cranked shaft, available through an arch of the right forward wheel). For deduction of a cranked shaft of the engine from a provorachivaniye if the engine is established in the car, the assistant should include any transfer and press a brake. If the engine is removed from the car, hold a cranked shaft from a provorachivaniye a wrench for the central bolt of a cranked shaft.
8. Weaken a bolt of fastening of a pulley механиз ма tension of a gear belt, then take away a pulley from a gear belt and remove a gear belt from pulleys (see fig. Arrangement of a bolt of fastening of a pulley of the mechanism of a tension of a gear belt).
9. Remove a hose of ventilation of a case from a cover of a head of the block of cylinders.
Unscrew two bolts and uncover, closing spark plugs (see fig. Removal of the cover closing spark plugs). Mark high-voltage wires, then remove them from spark plugs and disconnect from a cover of a head of the block of cylinders.
10. Gradually and consistently unscrew 12 bolts and uncover heads of the block of cylinders (see fig. Unscrewing of a bolt of fastening of a head of the block of cylinders).
11. Remove continuous rubber laying of a cover of a head of the block of cylinders (see fig. Arrangement of continuous rubber laying of a cover of a head of the block of cylinders).
12. Holding a camshaft from a provorachivaniye a wrench for лыски, unscrew a bolt of fastening of a pulley of a camshaft (see fig. Wrench use for camshaft keeping from a provorachivaniye).
13. Remove a pulley from a camshaft, then similarly remove a pulley from the second camshaft.
14. Unscrew a bolt and remove a gear pulley of a cranked shaft. For prevention of a provorachivaniye of a cranked shaft when unscrewing a bolt of fastening of a pulley screw on a pulley two bolts a steel plate or, using a screw-driver or the lever, block a gear wreath of a flywheel. After unscrewing of a bolt of fastening of a pulley, remove a pulley of a cranked shaft, using a stripper.
15. Unscrew the central bolt and remove a pulley of the mechanism of a tension together with an arm (see fig. Pulleys of a gear belt). Remove the rasporny plug from a bolt of fastening of a pulley.
16. Remove a back casing of a gear belt for what previously unscrew the top and average are resistant for screws of fastening of an external casing of a gear belt. Keep in mind that the top rack is simply unscrewed from a head of the block of cylinders, and average is screwed by a bolt. Unscrew two top and one right bottom bolt of fastening of a back casing of a gear belt and remove it (see fig. An arrangement of the top rack for the screw of fastening of an external casing of a gear belt and the top bolts of fastening of a back casing, the Arrangement of the right bottom bolt of fastening of a back casing of a gear belt).
