At installation of a new belt it is possible to do without the put marks (see п 3.7.3). At installation gear приводного a belt any of pistons should not be in position ВМТ, differently valves can strike on pistons. Put on a gear belt gear pulleys of cranked, distributive and intermediate shaft. At installation of a gear belt avoid its sharp excesses. Adjust a tension gear приводного a belt as follows:

Fig. 150. Check of a tension of a gear belt

- Wrench turn шестигранник a tension roller in a direction shown on fig. 150, thereby pulling a gear belt;

- Check up a tension of a gear belt: it is considered normal if in an average part of a branch between pulleys of distributive and cranked shaft the belt twists on 90 ° (see fig. 150);

- Tighten a nut of fastening of an axis of a tension roller the moment 45 Н·м;

- Turn a cranked shaft on two complete revolutions and be convinced that the belt tension has not changed;

- Establish the top and bottom parts of a protective cover of a gear belt and belt pulleys;

- Adjust a tension поликлинового a belt (see подразд. 3.8);

Fig. 151. Fastening of a support of an engine mount (on the forward party of the engine): 1 — a bolt, 55 Н·м; 2 — a bolt, 20 Н·м; 3 — an engine mount collar

- Turn by hand and definitively tighten bolts 1 and 2 (fig. 151) fastenings of a support of an engine mount by following moments:

  - Bolt       1 55 Н·м;

  - Bolt       2 20 Н·м;

- Avoid an excessive tension of a gear belt as it considerably reduces term of its service;

- Establish a cogwheel (if it acted in film), wrap a fastening bolt (preliminary having greased it), tighten the moment 90 Н·м then tighten a bolt for 90 °. The engine should be thus fixed in a motionless condition.

The note At installation of a cogwheel of a cranked shaft the bolt of its fastening should be necessarily replaced with the new.
