Removal and installation shock-absorber/dismantling of a depreciation rack

Elements of a depreciation rack

1 — the Nut with a fillet, 50 Nanometers which is self-stopped surely replace
2 — a shock-absorber Support
3 — the Washer
4 — the Support
5 — the Screw spring

6 — the Additional spring
7 — the Protection cover
8 — the Protective cap
9 — a spring Support lower
10 — the Plate of a spring lower
11 — the Shock-absorber

Removal

 PERFORMANCE ORDER

  1. Remove a depreciation rack.
  2. The depreciation rack can deal only with use of the special tool.

The spring of a depreciation rack is compressed by big effort. For removal of the shock-absorber it is necessary to squeeze a spring special adaptation.

Do not remove the shock-absorber at all if the spring is reliably not compressed. At installation of device for compression of a spring you watch that rounds of a spring were reliably captured and adaptation could not slide off. The spring is compressed by big effort. Use only the reliable tool. Do not connect a spring by a wire at all. Danger of accident!

  1. Clamp a spring with a tip in a vice.
  1. Squeeze a spring the corresponding adaptation. HUNDRED AUDIS use V.A.G 1752/1 (1) device to this purpose.
  1. At compression you monitor the correct provision of a spring in adaptation (an arrow on an accompanying illustration). (1) – the device for compression, (2) – a support for spring rounds.
  1. Squeeze a spring so that the top plate was released.
  2. Turn off a nut with a fillet of fastening of a rod. At the same time hold a rod from a provorachivaniye a face key for an internal hexagon. The special tool (2, 3 and 4) shown on an illustration 4.3 is for this purpose necessary (HAZET 4910/13 or AUDI-T10001/7, T10001/11 and T10001/3).
  3. Remove the compressed spring together with the device for compression.
  1. Remove the protection cover (1) and the lower support of a spring (2).
  1. Mark the provision of the lower plate in relation to the shock-absorber (4).
  2. Disconnect a plate (3) by means of the plastic hammer and remove upward.

Installation

There are springs of various groups of the admission. It is necessary to apply only springs with an identical color tag. It is recommended to replace springs and shock-absorbers in couple, i.e. on both sides of the car.

 

 PERFORMANCE ORDER

  1. Clamp a new cartridge of the shock-absorber with a tip in support of a depreciation rack or in a vice with slips.

  1. Transfer to the new shock-absorber a tag from old. Carefully by means of the plastic hammer install the lower plate of a spring against the stop on the shock-absorber. At the same time you watch that the tag on a plate coincided with a tag on the shock-absorber.

    And — a shock-absorber Axis / the bearing lever
    I \Left depreciation rack,
    In = 65 ± 2 °
    II \Right depreciation rack,
    With = 87 ± 2 °

  1. The provision of the lower plate is defined by the sizes specified illustrations.
  2. The cut of a plate (shooter) has to provide access to a body.
  1. Establish into place the lower support of a spring and the protection cover.
  1. Establish into place the compressed spring together with the device for compression. The end of a round of a spring has to adjoin to an emphasis.
  1. Establish a shock-absorber support with the top support of a spring on the compressed spring so that the support of a spring adjoined to the end of a round of a spring (an arrow on an accompanying illustration). The deviation in limits ± 2 ° is allowed.
  1. Establish a washer and a support of the shock-absorber.

You watch that the end of a spring adjoined to an emphasis of the top support of a spring.

  1. Tighten a new nut with a fillet the special tool the moment of 50 Nanometers. Do not unclench a spring yet.
  2. Press vertically depreciation rack the device for V.A.G 1752/2 compression.
  1. Release the lower lock lever and turn the top plate of a spring so that the scale of a support of a depreciation rack stood on a mark 7 °.
  1. You watch that the ends of a spring adjoined to an emphasis of the top and lower support of a spring.

    I \At the left in the direction of the movement
    II \On the right in the direction of the movement
    And — a shock-absorber Axis / the bearing lever
    B — the Angle of installation

  1. Fix the lock lever.
  2. The lever of a support of a spring of V.A.G 1752/2 adaptation (shooter) has to coincide with the center of a support.
  3. Carefully weaken the device for compression of a spring and take out it.
  4. Check adjustment. If necessary, repeat the procedure.
  5. Establish into place a depreciation rack, address appropriate section.
