4.8.8.3. Adjustment of a tension of a chain


Section of a natyazhitel of a chain


1 – the cap-type nut;
2 – case of a natyazhitel;
3 – core;
4 – spring ring;
5 – plunger spring;
6 – washer;
7 – plunger;
8 – spring;
9 – cracker;
10 – spring ring

Scheme of the mechanism of the drive of the camshaft and subsidiary bodies

1 – camshaft asterisk;

2 – chain;

3 – uspokoitel of a chain;

4 – asterisk of the roller of the drive of the oil pump;

5 – asterisk of a bent shaft;

6 – restrictive finger;

7 – boot of a natyazhitel;

8 – natyazhitel of a chain

To weaken a nut 1 (fig. Section of a natyazhitel of a chain). At the same time the core 3 is released and the chain stretches a boot 7 (fig. Scheme of the mechanism of the drive of the camshaft and subsidiary bodies), on which through a plunger 7 (see rice. The section of a natyazhitel of a chain) works a spring 8.

To turn a bent shaft on 1–1,5 turns in the direction of rotation. At the same time the spring of a natyazhitel operating on a boot will automatically adjust a chain tension.

To tighten the cap-type nut 1 thanks to what the core 3 is clamped by grips of a cracker 9, and during the operation of the engine the plunger 7 is affected only by a spring 5. This spring wrings out a plunger from a head of a core 3, and between them during the operation of the engine flows the oil playing a shock-absorber role at blows of a chain into a gap.

Thanks to the guaranteed gap of 0,2-0,5 mm between a core 3 and a plunger 7 at strong blows of a chain the spring 8 comes into effect.
