Fig. 414. Elements of the mechanism of the drive, located on the forward party of the engine: 1 — the top protection of a gear belt; 2 — a gear belt; 3 — a nut, 20 Нм; 4 — the clown of a tension roller; 5 — натяжитель a belt; 6 — a bolt, 45 Нм; 7 — a camshaft cogwheel; 8 — a bolt, 25 Нм; 9 — a roller; 10 — a bolt, 10 Нм; 11 — back protection приводного a belt; 12 — a cogwheel of the fuel pump of a high pressure; 13 — a pulley of an intermediate shaft; 14 — a cogwheel of a cranked shaft; 15 — a bolt, 90 Нм + 90 ; 16 — a nut, 55 Нм; 17 — the bottom protection of a gear belt; 18 — распорный a spring clip





Drive details газораспределительного the mechanism are shown on fig. 414. To reach details of a drive of the mechanism газораспределения, it is necessary to remove клиновой a belt of the pump of the hydraulic booster of a steering and поликлиновой a belt of a drive of the generator. Works are described in corresponding section.
The camshaft is put in action by a gear belt which passes through pulleys located on distributive and cranked shaft and ТНВД. The intermediate shaft is resulted by a pulley without gear gearing.
Once again we pay your attention that at work with the mechanism газораспределения it is necessary to have the special tool, for example for adjustment of a drive of the pump of a high pressure and a camshaft without which it is not necessary to make adjustment. As work of valves depends on correctness of adjustment of a drive of a camshaft wrong adjustment of a drive of a camshaft can manage very expensively. Always it is necessary to remember that the belt can jump on one tooth and it can lead to serious damage of the engine as valves will open and be closed during the wrong moment that will lead to serious damage of pistons. For this reason it is necessary to change a gear belt each 100 000 km as torn приводной can become the reason of similar damage.
For adjustment of a tension of a gear belt the special tool also is required. In case of need it is possible to adjust also a belt tension approximately, but we recommend to you after such adjustment at first possibility to check up a belt tension on HUNDRED. Check of a tension of a belt does not occupy a lot of time.
Following works should be spent only in the event that for you on hand are available the corresponding special tool. Otherwise it is necessary to address on HUNDRED.
Provided that the belt is not damaged, it has service life to 100 000 km.
The belt tension is regulated by the established tension roller with the adjusting clown.
