Camshaft drive belts
1 - crankshaft pulley; 2 - tension roller; 3 – a bolt of fastening of a tension roller; 4 - water pump pulley; 5 - camshaft drive belt; 6 – a pulley of an inlet camshaft; 7 – a bolt of fastening of a pulley; 8 – a belt of a drive of a final camshaft; 9 – a pulley of a final camshaft; 10 – a bolt of fastening of a pulley; 11 - tension roller of the exhaust camshaft drive belt; 12 – a bolt of fastening of a tension roller; 13 - guide roller
1. Remove the upper engine cover (see subsection 2.1).
2. Remove the air filter (see subsection 4.1).
3. Release the latches and remove the top cover 1 (see pic. Camshaft drive parts for 1.4 l, 55 and 74 kW engines).
4. Set the piston of the first cylinder to TDC (see subsection 2.2.1).
5. Remove the expansion tank without disconnecting the hoses from it, and set it aside.
6. Hook the engine with a hoist and tighten its cables to unload the supports.
7. Turn away bolts of fastening of the right support of the power unit to the engine and a body.
8. Remove the alternator drive belt (see subsection 2.3).
9. While holding the crankshaft from turning, unscrew the bolt 24 securing the crankshaft pulley.
10. Remove the alternator drive pulley 23. Screw the bolt 24 with two thick washers by hand so that the pulley 19 does not come off the crankshaft.
11. Unscrew the fastening bolts 22 and remove the bottom cover 26.
12. Loosen bolt 3 (see fig. Camshaft drive belts) so that the tension roller 2 turns and loosens the tension of the belt 5 of the camshaft drive.
13. Remove belt 5 of the camshaft drive.
14. Loosen the bolt 12 and turn the tension roller 11 to loosen the tension of the belt 8. Secure the camshafts from turning by inserting 8 mm drills into the holes a.
15. Remove the belt 8 of the exhaust camshaft drive. Thoroughly clean the pulleys and rollers of dirt and oil.
16. Slide the new belt onto the exhaust camshaft pulley 9 and then onto the intake camshaft pulley 6. In this case, the upper branch of the belt must be tense.
17. With a hexagon inserted into the hole, turn the tension roller 11 (see fig. Camshaft drive belts) so that pointer 1 coincides with protrusion 2 on the frame of the tensioner. Holding the tension roller in this position, tighten the bolt 3 of the roller mounting to 20 Nm.
18. Put on the belt 5 (see fig. Camshaft drive belts) on the water pump pulley 4 and the tension roller 2, then on the crankshaft pulley 1 and the idler roller 13 and then on the intake camshaft pulley 6.
19. With the hexagon inserted into the hole, turn the tension roller 3 so that the pointer 1 of the roller is opposite the smaller groove in the plate 2. At the same time, pay attention to the fact that the bolt 5 must be in the larger groove of the plate 2. Holding the tension roller in this position, tighten roller fastening bolt torque 20 Nm (4 - hexagon).
20. Rotate the crankshaft two turns and check that the TDC marks match.
21. Install all removed parts in reverse order. Please note that bolt 24 (see pic. Camshaft drive parts for 1.4 l, 55 and 74 kW engines) the fastening of the crankshaft pulleys and the bolts of the power unit support to the engine and body must be replaced with new ones. Tighten the crankshaft pulley bolt in two stages: 1st - with a torque of 90 Nm, 2nd - tighten another 90°. The tightening torque of the power unit support bolts is 50 Nm.
