Fig. 12–5. Elements absorber racks: 1 – a nut with a fillet, 50 Нм; 2-raspornaja the plug; 3 – the top support absorber racks; 4 – a washer; 5 – the top support of a spring; 6 – a cylindrical spring; 7 – the buffer; 8 – a protective cover; 9 – a protective casing; 10 – the bottom support of a spring; 11 – the bottom plate of a spring; 12 – the shock-absorber
|
Fix амортизаторную a rack (fig. 12–5) a forward suspension bracket in the adaptation fixed in a vice, and by means of special adaptation V.A.G 1752/6 compress a spring so that it has departed from the top part of a rack. At use of the special adaptation for compression of springs spring coils it is necessary to grasp and compress reliably a spring from opposite sides.
The prevention
The spring has very big effort of compression, therefore use only very reliable tool. At all do not connect a spring a wire.

Fig. 12–6. Unscrewing of the central nut of fastening of a rod of the shock-absorber
|
Having fixed a key a rod of the shock-absorber from проворачивания, by means of another накидного a key or a special key 3353 unscrew the central nut of fastening of a rod of the shock-absorber (fig. 12–6).
Remove from a shock-absorber rod распорную the plug, the top support absorber racks, a washer and the top support of a spring.
Remove a spring together with the adaptation for spring compression.

Fig. 12–7. An arrangement of a protective casing (1), support of a spring (2) and the bottom plate of a spring (3) on absorber to a rack
|
Remove a protective casing 1 (fig. 12–7) and the bottom support of a spring 2. Using a plastic hammer, bring down upwards the bottom plate of a spring 3.
Installation
At installation it is necessary to use on one axis of the car of a spring with identical technical characteristics (with identical marks on colour).
Check up the shock-absorber on absence подтекания liquids. Check up on all length a shock-absorber rod on absence of dot corrosion. Check up the shock-absorber case on absence of mechanical damages. Establish the shock-absorber in vertical position and check up its work, moving a rod at full capacity, and also upwards and downwards for the length of 50-100 mm. In all cases the shock-absorber rod should move smoothly, with notable resistance. If the shock-absorber rod moves jerky or there are mechanical damages, it is necessary to replace the shock-absorber.
Fix the shock-absorber in a vice with soft sponges.

Fig. 12–8. Correct position of an aperture at installation of the bottom plate of a spring on the shock-absorber: 1 – the bottom plate of a spring; 2 – the shock-absorber; And – an axis of a plug of the bottom fastening of the shock-absorber; In – clips
|
Establish the bottom plate of a spring on the shock-absorber so that the aperture in a spring plate was perpendicular to an aperture in a plug of the bottom fastening of the shock-absorber, thus clips should settle down from outside apertures (fig. 12–8). The deviation of the centre of an aperture in the bottom plate of a spring from a vertical should be no more 2 .
Establish the bottom support of a spring and a protective casing.

Fig. 12–9. A correct arrangement of the bottom coil of a spring in a plate
|
Establish a cylindrical spring so that its bottom end has correctly settled down in the bottom plate of a spring (fig. 12–9).
Establish the top plate of a spring so that an axis passing through fixing carving racks, axes of the bottom fastening absorber racks settled down in parallel . The deviation no more 2 is supposed.
Keeping a rod of the shock-absorber from проворачивания, screw a new nut with a fillet of fastening of a rod of the shock-absorber and tighten its moment 50 Нм (fig. 12–6 see).
Being careful, remove the adaptation for spring compression.

Fig. 12–10. A correct arrangement of the top coil of a spring on absorber to a rack
|
Check up, that the top coil of a spring has correctly settled down on the top plate of a spring (fig. 12–10).
Establish амортизаторную a rack on the car.
