4.2.4. Check of a tension of a belt of the drive of the gas-distributing mechanism

Regularly check a state and a tension of a belt of the drive of the gas-distributing mechanism, if necessary adjust a tension. When weakening a tension of a belt its teeths quickly wear out and besides jumping of a belt on cogged pulleys cranked and camshafts is possible that leads to violation of installation of phases of gas distribution, loss of power, damage of the engine.
You will need a key hexagon "on 6".
1. Turn out five bolts of fastening of the top cover of a belt of the drive of the gas-distributing mechanism …
2. … also uncover.
3. Check a tension of a belt of the drive of the gas-distributing mechanism pressing of a finger with effort of 100 N (10 kgfs) to the middle of a branch of a gear belt between pulleys of camshafts and measure a deflection of a gear belt — the belt has to cave in no more than on 5–7 mm.
4. Check is also carried out under the provision of a tag 1 on an external holder of a tension roller which has to be opposite to a ledge 2.
5. If a condition of a belt of the drive of the gas-distributing mechanism or its tension unsatisfactory, then respectively replace a belt or adjust its tension (see. "Replacement of a belt of the drive of the gas-distributing mechanism and tension roller").
6. Establish all details in the sequence, the return to removal.
