Withdrawal
1. Turn out a bolt of fastening of a pulley of the water pump.
2. Turn out a bolt of fastening of the generator.
3. Remove the water pump pulley and drive belt.
4. Remove the crankshaft pulley.
5. Remove a casing of a gear belt.
6. By turning the crankshaft, set the piston of the 1st cylinder to the TDC position at the end of the compression stroke, while the marks on the camshaft and crankshaft pulleys must be aligned with the alignment marks on the engine.
7. Loosen the tension roller mounting bolt, move the roller to the water pump and tighten the bolt.
8. Remove the toothed belt.
Note. Mark the direction of rotation of the toothed belt to reinstall it in its original position.
9. Turn out a bolt and remove a pulley of a camshaft.
10. Turn out a bolt of fastening of a pulley of a cranked shaft.
11. Remove the toothed belt tensioner.
Examination. Toothed belt
1. Check the toothed belt for oil, water or dust. Replace belt if necessary. Minor marks should be wiped off with a dry cloth or paper. Do not clean the toothed belt with solvent.
2. After repairing the engine or adjusting the belt tension, check the condition of the belt. If the following defects are present, replace the toothed belt.
Pulleys and idler
1. Check the camshaft pulley, crankshaft pulley and idler pulley for uneven wear, cracks or damage.
2. Check the ease and smoothness of rotation of the tension roller, as well as the absence of extraneous noise during rotation.
Installation
1. Install the flange and crankshaft pulley as shown in the figure. Pay attention to the direction of their installation.
Tightening torque of the crankshaft pulley bolt: -1.3L engine: 140-150Nm -1.1L engine: 70-100Nm
2. Install the camshaft pulley and secure with a bolt, tightening it to the required torque.
Tightening torque: 100–120 Nm.
3. Align the alignment marks on the pulleys of the camshaft and crankshaft with the pointers, while the piston of the first cylinder should be set to TDC on the compression stroke.
Note. When installing the crankshaft pulley, the pulley pin must fit into the hole in the crankshaft pulley.
4. Move the toothed belt tensioner as close as possible to the water pump and tighten the bolt of its fastening.
5. Insert the end of the tension roller spring into the hole in the roller bracket and use a screwdriver to insert the other end of the spring behind the front cover of the cylinder block.
6. Install the toothed belt on the pulleys in the following order:
- crankshaft pulley;
- camshaft pulley;
- tension roller.
7. Install the toothed belt so that its leading branch has a slight deflection.
Note. Tension the drive branch of the belt by turning the camshaft pulley in the opposite direction to the normal direction of rotation, and check the alignment of the alignment marks.
8. Loosen the tension roller mounting bolt and release the tension roller spring.
9. Turn the crankshaft clockwise a full 2 teeth on the pulley (at 15°).
10. Press the tension roller in the direction of the arrow and check that the toothed belt is correctly seated on the pulleys.
11. Make sure that the belt is tight and in this position tighten the tension roller mounting bolt so that only its spring has free play.
12. Turn the crankshaft pulley two turns clockwise to properly seat the toothed belt on the pulleys.
13. Check the toothed belt tension (engine 1.3 l). When pressing the tension roller and on the tensioned branch of the toothed belt with a force of 49 N, the toothed belt should bend to the center of the head of the tension roller fastening bolt.
Make sure that when compressing the middle part of the drive belt with your thumb and forefinger, the distance between the back of the belt and the center of the hole for the toothed belt cover mounting bolt in the cylinder block is approximately 20 mm (engine 1.1 l).
