Fig. 106. Details of a drive of the mechanism of a gazoraspredeleniye: 1 — bolts, 55 N · m; 2 — a bolt, 20 N · m; 3 — an engine mount collar; 4 — the top part of a protective cover; 5 — a roller of the tension adaptation; 6 — a dustproof cap; 7 — bolts, 10 N · m; 8 — the lower part of a protective cover; 9 — a pulley of a drive of the pump of system of cooling; 10 — poliklinovy a belt; 11 — a flywheel; 12 — maple a belt; 13 — a pulley of the pump of system of cooling; 14 — a bolt, 25 N · m; 15 — a pulley of a cranked shaft; 16 — a bolt, 25 N · m; 17 — the lever of the tension adaptation of a poliklinovy belt





- unscrew bolts of fastening and remove the top part of a protective cover 4 (see fig. 106 ) a gear belt;
- mark the provision of a pulley 15 cranked shaft or a quencher of fluctuations in relation to a cogwheel of a cranked shaft;
- include the fifth transfer, establish the car on the parking brake and turn out bolts of fastening of both pulleys, or respectively a quencher of fluctuations. The last can be established only in one situation in order that openings were combined;
- unscrew bolts of fastening and remove the lower part 8 protective covers of a gear belt;

Fig. 149. Device of a tension of a gear belt: a — the movement direction for a belt tension; b — the movement direction for weakening of a tension of a belt; c — a place of check of force of a tension of a belt; R — a tension roller





- weaken a nut of fastening of an axis of a tension roller (fig. 149) and turn it in such situation at which the gear belt will be most weakened;
- mark the direction of movement of a gear belt on its outer side (marker) and remove a belt from pulleys.
