Dismantling

PERFORMANCE ORDER
1. To remove the top cover of a drive of a camshaft (fig. of the Detail of a drive of a camshaft see).
2. To turn away bolts of fastening and to remove a pulley of the water pump.
3. To establish the piston of 1st cylinder in century of m. т. A compression step (both valves are closed). The label on a pulley of a cranked shaft should be combined with an arrow on the bottom cover of a drive of a camshaft.
4. To turn away four bolts and to remove a pulley of a cranked shaft.
5. To remove the bottom cover of a drive of a camshaft.
6. To weaken a nut of fastening of the mechanism of a tension of a belt and to turn a key эксцентриковую an axis натяжителя a belt counter-clockwise, to weaken a belt tension.
7. To remove a belt from cogwheels of a cranked shaft, рапределительного and intermediate shaft and with натяжителя the tension mechanism.
8. To turn away a nut and to remove натяжитель.
9. To turn away a bolt and to remove a cogwheel of an intermediate shaft, to take out шпонку.
10. To turn away a bolt and to remove a cogwheel of a cranked shaft, to take out шпонку.
11. To turn away a bolt and to remove a cogwheel from a camshaft, to take out шпонку.
12. To turn away bolts and to remove a back cover of a drive of a camshaft.

Assemblage and adjustment

PERFORMANCE ORDER
1. To establish a back cover of a drive of a camshaft and to tighten bolts of its fastening.
2. To insert шпонку into a groove on cranked to a shaft and to establish a cogwheel. To put on a carving of a bolt 14 hermetic, to screw a bolt with a washer and to tighten the moment 200 Н·м (20,0 кгс·м).
3. To insert шпонку into a groove on distributive to a shaft, to establish a cogwheel, to screw a bolt with a washer and to tighten the moment 80 Н·м (8,0 кгс·м). The label on a cogwheel should coincide with the top plane of a lining of a cover of a head of cylinders on the left side of the engine.
4. To insert шпонку into a groove of an intermediate shaft, to establish a cogwheel, to screw a bolt 12 with a washer and to tighten the moment 80 Н·м (8,0 кгс·м).
5. To establish the mechanism of a tension of a belt of a drive of a camshaft.
6. Temporarily to establish a pulley 4 cranked shaft on a cogwheel 13. The piston of 1st cylinder should be in century of m. т. To turn a cogwheel 11 intermediate shaft so that a label on it it was combined with a label on a pulley 4 cranked shaft, as is shown in drawing.
7. To put on a belt 9.
8. To turn a key 3 (fig. Adjustment and check of a tension of a belt of a drive of a camshaft see) the mechanism of 1 tension of a belt 5 clockwise for a preliminary tension of a belt. To check up, that labels of century of m. т. Have not moved a little. To turn the mechanism of 1 tension further clockwise, having pulled a belt 5 so that it could be developed on 90 °, undertaken it two fingers in the middle between distributive and intermediate shaft. Keeping a key 3 mechanism of a tension, to tighten a nut of its fastening by a key 2.
9. To remove a pulley 4 cranked shaft. To establish the bottom cover 7 drives of a camshaft (fig. of the Detail of a drive of a camshaft see).
10. To establish a pulley of a cranked shaft, to tighten bolts 3 moment 20 Н·м (2,0 кгс·м).
11. To establish a pulley of the water pump.
12. To establish the top cover of a drive of a camshaft.
