1. Remove the top casing of the engine (see subsection 2.1). |
2. Remove the air filter (see subsection 4.1). |
3. Unfasten latches and remove the top cover 1 (cm. rice. Details of the drive of camshafts of engines of 1,4 l, 55 and 74 kW). |
4. Install the piston of the first cylinder in VMT (see subsection 2.2.1). |
5. Remove a broad tank, without disconnecting from it hoses, and put it aside. |
6. Hook on the engine a waist and pull its cables to unload support. |
7. Turn off bolts of fastening of the right support of the power unit to the engine and a body. |
8. Take off a generator drive belt (see subsection 2.3). |
9. Holding a bent shaft from a provorachivaniye, turn off a bolt 24 fastenings of a pulley of a bent shaft. |
10. Remove a pulley 23 drives of the generator. Screw manually a bolt 24 with two thick washers that the pulley 19 did not come off a bent shaft. |
11. Turn off bolts 22 fastenings and remove the lower cover 26. |
12. Weaken an inhaling of a bolt 3 (see rice. Belts of the drive of camshafts) so that the tension roller 2 turned and weakened a tension of a belt 5 of the drive of camshafts. |
13. Take off a belt 5 of the drive of camshafts. |
14. Weaken an inhaling of a bolt 12 and turn a tension roller 11 to weaken a belt 8 tension. Fix camshafts from a provorachivaniye, having inserted into openings and drills with a diameter of 8 mm. |
15. Take off a belt 8 of the drive of the final camshaft. Carefully clear pulleys and rollers of dirt and oil. |
16. Put on a new belt a pulley of the 9th final camshaft, and then a pulley of the 6th inlet camshaft. At the same time the top branch of a belt has to be tense. |
|
17. The hexagon inserted into an opening turn a tension roller 11 (see rice. Belts of the drive of camshafts) so that the index 1 coincided with a ledge 2 on a frame of the tension device. Holding a tension roller in this situation, tighten a bolt 3 fastenings of a roller the moment of 20 N · m. |
18. Put on a belt 5 (see rice. Belts of the drive of camshafts) on a pulley 4 water pumps and a tension roller 2, then on a pulley of 1 bent shaft and the directing roller 13 and after that on a pulley of the 6th inlet camshaft. |
|
19. The hexagon inserted into an opening turn a tension roller 3 so that the index of 1 roller rose opposite to a smaller groove in a plate 2. At the same time pay attention that the bolt 5 has to be in a bigger groove of a plate 2. Holding a tension roller in this situation, tighten a bolt of fastening of a roller the moment of 20 N · m (4 – a hexagon). |
20. Turn a bent shaft on two turns and check coincidence of tags of VMT. |
21. Establish all removed details upside-down. At the same time consider that a bolt 24 (cm. rice. The detail of the drive of camshafts of engines of 1,4 l, 55 and 74 kW) fastenings of pulleys of a bent shaft and bolts of fastening of a support of the power unit to the engine and a body needs to replace with new. Tighten a bolt of fastening of pulleys of a bent shaft in two stages: the 1st – the moment of 90 N · m, the 2nd – tighten for 90 °. The moment of an inhaling of bolts of fastening of a support of the power unit – 50 N · m. |
