Dismantling of an amortisation rack / of the shock-absorber. Removal and installation of a screw spring

Amortisation rack


1 — the shock-absorber
2 — a protective cover
3 — a support
4 — the bottom support of a spring
5 — a nut
   The inhaling moment on a rod:
     -  At external шестиграннике
65 Nanometers
     -  At internal шестиграннике
45 Nanometers

6 — a protective cap
7 — the top cup of a spring
8 — the plastic buffer of a course of compression


9 — a screw spring
10 — the bottom cup of a spring
11 — a nut
12 — a bolt
Execution only for the bad
Roads (Eastern Europe)

13 — an adapter
14 — a ring
15 — a sealing ring
16 — a washer
17 — a washer
18 — a finger


Springs of one axis are replaced only in steam. It is necessary to apply springs with identical number BMW. Spring number is put on its end.


 REMOVAL

1. Remove an amortisation rack, address to Section Removal and installation of an amortisation rack.

2. For shock-absorber removal it is necessary to compress a screw spring. Compress a spring by means of the special adaptation. To protection of a surface of a spring apply a plastic lining.

At all do not remove the shock-absorber if the spring is not compressed.

3.

Insert the device for spring compression into coils so that it has strongly clasped coils and possibility соскальзывания was excluded. The screw spring has very big rigidity. Therefore apply only the serviceable adaptation. At all do not apply to compression of a spring a wire. There is a danger of accident!

4. Turn away a nut накидным a key. Thus the rod depending on execution is kept by a key under internal шестигранник or накидным a key.

The nut has very big moment отворачивания. If necessary it is possible to strike blow by a hammer to a key.

5. Remove a washer.
6. Remove a support with a sealing ring and a washer.
7. Remove the top plate of a spring with a lining and a spring. Take out the shock-absorber from a spring.

If the spring is replaced only, slowly unclench it. If it is necessary to remove only the shock-absorber, springs it is not unclenched.

8. Remove the plastic buffer of a course of compression, a protective cover and the bottom plate.


 INSTALLATION

1. The new spring has a protective anticorrosive covering. Before installation check up integrity of a covering. If necessary eliminate damages.
2. Check up a protective cover, the plastic buffer of a course of compression and a plate. In the presence of damages replace details.
3. Enter the shock-absorber with the bottom plate, the buffer and a protective cover into the compressed spring.
4. Collect an amortisation rack according to иллюстр. 4.0а and 4.0b. Watch that the spring adjoined to fillets of the bottom and top plates.
5. Screw on some coils a new self-stopped nut.
6. Slowly unclench a spring so that it thus adjoined to plates. Watch correct position of the bottom cup of a spring (rectangular grooves).
7. Tighten a nut of fastening by the moment of 65 Nanometers (at internal шестиграннике on a rod the moment of 45 Nanometers). Keep from проворачивания a rod. Repair trucks apply head BMW-312210 to observance of the moment of an inhaling or HAZET 2593-* (* - the size of a key).
8. Completely unclench a spring and remove the adaptation for compression.
9. Establish an amortisation rack.
