3. Remove a belt of a drive of the pump of the amplifier of a steering and / or the conditioner compressor.

4. Loosen the bolts of fastening of the generator and an adjusting bolt of a tension of a belt of a drive of the generator.

5. Turn out bolts of fastening of the generator.

6. Remove a pulley of the water pump.

7. Turn out bolts and remove a pulley of a drive of hinged units and directing plate of a gear belt from a cranked shaft.

8. Turn out bolts and remove the top and bottom casings of a gear belt.

9. Turn a cranked shaft so that the adjusting label on a pulley of a drive of a gear belt of a cranked shaft was combined with the index on the block of cylinders of the engine.

10. Check up that the label I on a pulley of a camshaft of inlet valves was combined with the index on a cover of a head of the block of cylinders and label Е on a pulley of a camshaft of final valves was combined with the index on a cover of a head of the block of cylinders.

The prevention
After combination of labels with indexes do not turn distributive and cranked shaft.

11. Loosen the a bolt of fastening of a roller of the mechanism of a tension of a gear belt.
12. Protect a gear belt pure rags.
13. Remove a roller of the mechanism of a tension.
14. Remove a gear belt from the engine.

The prevention
Note a direction of rotation of a gear belt for its repeated installation in initial position.

Check

The prevention
Strongly do not bend a gear belt and do not change a direction of its rotation. Do not allow oil and lubricant to contact with a gear belt as it will lead to its destruction.

PERFORMANCE ORDER

1. Replace a gear belt if it is polluted by oil or lubricant.

2. Check up a gear belt on absence of damages, deterioration, stratification, cracks on teeths and in the basis of teeths, and also on defects at end faces and a belt underside. In the presence of defects, replace a gear belt.

3. Bend a gear belt on a circle, in diameter 25 mm and check up absence on it of cracks and stratifications.

4. Rotating a roller of the mechanism of a tension of a gear belt, check up absence of jammings, smoothness and ease of its rotation.

5. Check up a condition of pulleys of a gear belt distributive and cranked shaft on absence of deterioration and the broken teeths. If necessary replace pulleys.

Installation

ENGINE A5D

PERFORMANCE ORDER

1. Establish a roller of the mechanism of a tension of a gear belt.

The prevention
At replacement of a gear belt necessarily replace a spring of the mechanism of a tension of a gear belt

2. Take away a roller of the mechanism of a tension of a gear belt on the maximum distance and fix its bolt in this position.

3. Check up that the label on a pulley of a gear belt of a cranked shaft is combined with the index on the block of cylinders.

4. Check up that the label I on a pulley of a camshaft of inlet valves is combined with the index on a cover of a head of the block and label Е on a pulley of a camshaft of final valves is combined with the index on a cover of a head of the block of cylinders.

The prevention
At repeated installation of a gear belt, establish it according to earlier put labels.

5. Establish a gear belt on the pulley of a cranked shaft directing a roller, a pulley of a camshaft of final valves, a pulley of a camshaft of inlet valves and a roller of the mechanism of a tension.

6. Check up that the gear belt does not sag on a branch between a roller of the mechanism of a tension and a pulley of a camshaft of final valves or between pulleys of camshafts.

7. Loosen the the bolt of fastening of a roller of the mechanism of a tension of a gear belt therefore under the influence of a spring the roller will turn and will make a tension of a gear belt.

The prevention
Do not spend an additional tension of a gear belt.

8. Tighten a bolt of fastening of a roller of the mechanism of a tension of a gear belt.
The inhaling moment: 38–51 Nm

9. Turn clockwise a cranked shaft of the engine on two complete revolutions and combine a label on a pulley of a gear belt of a cranked shaft with the index on the block of cylinders of the engine.

10. Check up that a label I on a pulley of a camshaft of inlet valves and label Е on a pulley of a camshaft of final valves were combined with indexes on a cover of a head of the block of cylinders.

11. If labels were not combined with indexes, remove a gear belt and repeat operations on its installation.
12. Check up a tension of a gear belt. Press with effort of 10 kg the middle of a branch of a gear belt between pulleys of camshafts and measure a deflection of a gear belt.
Deflection: 11–13 mm

13. Establish the top and bottom casings of a gear belt and fix their bolts.
The inhaling moment: 7,9–10,7 Nm

14. Establish directing plate of a gear belt and a pulley of a cranked shaft of a drive of hinged units of the engine and fix their bolts.
The inhaling moment: 12,3–17,2 Nm

15. Establish a pulley of the water pump and fix bolts.
The inhaling moment: 12,3–17,2 Nm

16. Establish a belt of a drive of the generator and adjust its tension.
17. Establish a belt of a drive of the pump of the amplifier of a steering and the compressor of the conditioner and adjust its tension.
18. Connect a wire to the negative plug of the storage battery.

ENGINE A3E

PERFORMANCE ORDER

4. Check up that the camshaft label is combined with the index on a cover of a head of the block of cylinders.

The prevention
At repeated installation of a gear belt, establish it according to earlier put labels.

5. Establish a gear belt and check up absence of sagging of a belt between pulleys of cranked and distributive shaft.

6. Loosen the the bolt of fastening of a roller of the mechanism of a tension of a gear belt therefore under the influence of a spring the roller will turn and will make a tension of a gear belt.

The prevention
Do not spend an additional tension of a gear belt.

7. Tighten a bolt of fastening of a roller of the mechanism of a tension of a gear belt.
The inhaling moment: 18,6–25,5 Nm

8. Turn clockwise a cranked shaft of the engine on two complete revolutions and combine a label on a pulley of a gear belt of a cranked shaft with the index on the block of cylinders of the engine.

9. Check up that a label on a camshaft pulley were combined with the index on a cover of a head of the block of cylinders.

10. If labels were not combined with indexes, remove a gear belt and repeat operations on its installation.

11. Check up a tension of a gear belt. Press with effort of 10 kg the middle of a branch of a gear belt between a pulley of distributive and cranked shaft and measure a deflection of a gear belt.
