4.3.3. Check and adjustment of a tension of a belt of a drive of the gas-distributing mechanism

It be required to you: keys «on 10», «on 13», «on 19», an assembly shovel.

1. Remove the air filter for simplification of access (see. «Removal and installation of the air filter»).	2. A key «on 10» turn out two bolts of fastening of the top cover of a drive of the gas-distributing mechanism...

3.... also uncover.

4. Remove the right forward wheel.

5. Remove a belt of a drive of the pump of the hydraulic booster of a steering (see. «Replacement of a belt of a drive of the pump of the hydraulic booster of a steering»).

6. Remove a belt of a drive of the generator and the conditioner compressor (see. «Replacement of a belt of a drive of the generator and conditioner compressor»).

7. A key «on 19» turn out a bolt of fastening of a pulley of a drive of belts of the generator, the compressor of the conditioner and the pump of the hydraulic booster of a steering...	8.... also remove a pulley from a cranked shaft.

Good advice The bolt of fastening of a pulley of a drive of belts of the generator, the compressor of the conditioner and the pump of the hydraulic booster of a steering will tighten the big moment. To fix a cranked shaft from a provorachivaniye, include the V transfer and press a brake pedal (it the assistant should make).

9. A key «on 10» turn out two bolts of fastening of the bottom cover of a drive of the gas-distributing mechanism...	10.... also uncover.

11. Examine a belt of a drive of the gas-distributing mechanism. Replace a belt if at survey you find:

– oil traces on any surface of a belt;

– wear tracks of a gear surface, a crack, подрезы, folds and otsloyeny fabrics from rubber;

– cracks, folds, deepenings or cambers on an external surface of a belt;

– a razlokhmachivaniye or stratification on face surfaces of a belt.

Prevention With traces of engine oil on any its surface it is necessary to replace a belt, as oil quickly destroys rubber. On a belt (usually owing to violation of tightness of epiploons of cranked and distributive shaft) it is necessary to eliminate the reason of hit of oil immediately.

12. Check a belt tension. Correctly tense belt should turn on 90 ° from effort of fingers of 15-20 N (1,5–2 kgfs), the enclosed in the middle between pulleys cranked and distributive shaft. If necessary adjust a belt tension.	13. A key «on 13» weaken an inhaling of two bolts of fastening of an arm of a tension roller.

14. Insert an assembly shovel between an arm of the inlet pipeline and an arm of a tension roller. Shifting to the right an arm of a tension roller, pull a belt of a drive of the gas-distributing mechanism and tighten bolts of fastening of an arm the moment specified in the appendix 1.

15. Establish the removed details as it should be, the return to removal.
