2.2. Gear belt

Gear belt

1 – pulley of the water pump;
2 – pulley of a bent shaft;
3 – the directing plate of a gear belt;
4 – top casing of a gear belt;
5 – lower casing of a gear belt;
6 – gear belt;
7 - roller of a tension of a gear belt and spring;
8 – the directing roller;
9 – camshaft pulley;
10 – pulley of a bent shaft of the drive of a gear belt

Removal

PERFORMANCE ORDER
1. Disconnect a wire from the negative plug of the rechargeable battery.
2. Weaken bolts and nuts of fastening of the pump of the amplifier of steering. Having turned the pump, weaken a tension of a belt of the drive of the pump of the amplifier of steering and the compressor of the conditioner.
3. Take off a belt of the drive of the pump of the amplifier of steering and the compressor of the conditioner.
4. Weaken bolts of fastening of the generator and an adjusting bolt of a tension of a belt of the 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 the drive of hinged units and the directing plate of a gear belt from a bent shaft.
8. Turn out bolts and remove the top and lower casings of a gear belt.
9. Turn a bent shaft so that the adjusting tag on a pulley of the drive of a gear belt of a bent shaft was combined with the index on the block of cylinders of the engine.

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

Prevention

After combination of tags with indexes do not turn distributive and cranked shaft.


11. Weaken 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. Shoot a tension mechanism video.
14. Take off a gear belt from the engine.
Prevention

Note the direction of rotation of a gear belt for repeated installation it in initial situation.


Check


Prevention

Strongly do not bend a gear belt and do not change the 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 a gear belt for absence of damage, wear, stratification, cracks on teeths and in the basis of teeths, and also for defects at end faces and a reverse side of a belt. With defects, replace a gear belt.
3. Bend a gear belt on a circle, with a diameter of 25 mm and check lack on it of cracks and stratifications.
4. Rotating a roller of the mechanism of a tension of a gear belt, check lack of jammings, smoothness and ease of its rotation.
5. Check a condition of pulleys of a gear belt distributive and cranked in bulk for lack of wear and the broken teeths. If necessary, replace pulleys.

Installation
PERFORMANCE ORDER
1. Establish a roller of the mechanism of a tension of a gear belt.

Prevention

When replacing a gear belt surely 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 enshrine it by a bolt in this provision.
3. Check that the tag on a pulley of a gear belt of a bent shaft is combined with the index on the block of cylinders.
4. Check that the tag of I on a pulley camshaft of inlet valves is combined with the index on a cover of a head of the block and the tag E on a pulley of the camshaft of final valves is combined with the index on a cover of a head of the block of cylinders.
5. Establish a gear belt on the pulley of a bent shaft directing a roller, a pulley of the camshaft of final valves, a pulley of the camshaft of inlet valves and a roller of the mechanism of a tension.
6. Check that the gear belt does not sag on a branch between a roller of the mechanism of a tension and a pulley of the camshaft of final valves or between pulleys of camshafts.
7. Weaken a 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.

Prevention

You do not carry out 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.

Moment zatyazhki:ted: 37–52 N • BFD m: 38–51 N • m

9. Turn clockwise a bent shaft of the engine on two whole revolutions and combine a tag on a pulley of a gear belt of a bent shaft with the index on the block of cylinders of the engine.
10. Check that a tag of I on a pulley camshaft of inlet valves and a tag E on a pulley of the camshaft of final valves were combined with indexes on a cover of a head of the block of cylinders.
11. If tags were not combined with indexes, take off a gear belt and repeat operations on its installation.

12. Check a tension of a gear belt. Press with effort 10 kg the middle of a branch of a gear belt between pulleys of camshafts and measure a deflection of a gear belt.

Deflection:
TED: 9,0–11,5 mm
BFD: 9,0–11,0 mm

13. Establish the top and lower casings of a gear belt and fix them by bolts.

Inhaling moment: 7,9–10,7 N • m

14. Establish the directing plate of a gear belt and a pulley of a bent shaft of the drive of hinged units of the engine and fix them by bolts.

Inhaling moment: 12,3–17,2 N • m

15. Establish a pulley of the water pump and fix by bolts.

Inhaling moment: 12,3–17,2 N • m

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