- inspection pit or overpass;
- household steelyard.
Note: If there is no inspection ditch or overpass, the work can be done by removing the right front wheel (see "Preparing the car for maintenance and repair" and "Wheel - replacement"). You can determine the belt tension from above (from the engine compartment), but this requires practical experience, since access to the upper branch of the belt is difficult due to the right support of the power unit.
Sequence of execution
1. Remove the engine splash guard (see "Engine Mudguard - Removal and Installation").
Note: If you are doing the work without an inspection ditch, you do not need to remove the mudguard - just remove the right mudguard of the engine compartment (see "Engine compartment mudguards - removal and installation").
2. Apply a force of 98 N (10 kgf) to the alternator belt exactly in the middle between the alternator pulley and the engine crankshaft pulley.
(The original is available on the website VazBook)
Advice: If it is difficult to estimate the force created by the hand, you can use a household spring balance with a maximum permissible load of 10 kg.
Recommendation: A properly adjusted belt should deflect by 6-8 mm. If the belt deflection is not within the norm, adjust the belt tension.
3. With a socket wrench or open-end wrench by 13 mm using a ratchet, loosen the nut on the generator lower mounting bolt.
4. In the engine compartment with a spanner by 13 mm loosen the tension bar nut.
5. Turning with a spanner by 10 mm adjusting bolt, adjusting belt tension (clockwise increases the belt tension, and counterclockwise decreases it).
Warning: Excessive belt tension may cause failure of the alternator front bearing
6. Check the tension of the generator belt and repeat the adjustment if necessary.
7. After making sure that the belt is tensioned correctly, use a spanner by 13 mm tighten the tension bar nut.
8. With a socket wrench by 13 mm tighten the nut of the generator lower mounting bolt.
9. Install the removed parts (engine splash guard or mudguard and wheel).
