2.1.5. Adjustment of a tension of a chain of the drive of the mechanism of gas distribution

Drive of the mechanism of gas distribution of the engine of fashion. 2106

1 – camshaft asterisk;

2 – chain;

З – uspokoitel;

4 – asterisk of a shaft of the drive of the oil pump;

5 – asterisk of a bent shaft;

6 – tension boot;

7 – plunger of a natyazhitel;

8 – the fixing nut of a core of a natyazhitel

It is carried out on the cold engine at a run of the new car of 1,5 thousand km (after tightening of fastening of a head of cylinders) and further through each 15 thousand km, and also in case of the increased noise in the drive.

PERFORMANCE ORDER
Engine of fashion. 2106
1. To weaken the fixing nut 8 (see rice. Drive of the mechanism of gas distribution of the engine of fashion. 2106) a core of a natyazhitel, on her to eliminate with easy percussion of the hammer possible "zakusyvaniye" of a core and a special key to turn a bent shaft on 1–1/2 turns in the direction of its rotation.
2. At the same time the spring of a plunger influences a boot 6 of a natyazhitel through a plunger 7 and automatically establishes a necessary tension of a chain.
3. Upon termination of adjustment the fixing nut 8 needs to be tightened.
Engines of fashion. 331, 3317 and 3313

4. To weaken fastening of a clamping plate of a plunger of the tension device, having turned off on 1/2–2/3 turns a lock bolt (1). It is not necessary to turn off a lock bolt one size bigger specified as at the same time there can be its dissociation to a lock plate and the plunger of a natyazhitel will not be fixed in the chosen situation. It will lead to jumping of a chain on teeths of asterisks and, finally, to severe accident of the engine. A special key to turn a bent shaft of the engine on the rotation course on 2–3 turns and to tighten a lock bolt to the full, having recorded the new provision of an asterisk of the tension device.
