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 N · m; 4 — the clown of a tension roller; 5 — a natyazhitel of a belt; 6 — a bolt, 45 N · m; 7 — a camshaft cogwheel; 8 — a bolt, 25 N · m; 9 — a roller; 10 — a bolt, 10 N · m; 11 — back protection of a driving 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 N · m + 90 °; 16 — a nut, 55 N · m; 17 — the bottom protection of a gear belt; 18 — a rasporny spring clip

Details of a drive of the gas-distributing mechanism are shown on fig. 414 . To reach details of a drive of the mechanism of a gazoraspredeleniye, it is necessary to remove maple a belt of the pump of the hydraulic booster of a steering and poliklinovy a belt of a drive of the generator. Works are described in appropriate section.
The camshaft is put in action by a gear belt which passes through pulleys located on distributive and cranked shaft and TNVD. The intermediate shaft is given by a pulley without gear gearing.
Once again we pay your attention that at work with the mechanism of a gazoraspredeleniye 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 operation of valves depends on correctness of adjustment of a drive of a camshaft, the 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 the torn driving 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 the first possibility to check a belt tension on HUNDRED. Check of a tension of a belt does not take a lot of time.
The following works should be carried out only if 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 tension of a belt is regulated by the established tension roller with the adjusting clown.
