Springs of one axis are replaced only in pair. It is necessary to apply springs with the identical number BMW. Number of a spring is put on its end.


 REMOVAL

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

2. For removal of the shock-absorber 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 plastic laying.

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

3.

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

4. Unscrew a nut a cap key. Thus the rod depending on execution is kept by a key under an internal shestigrannik or a cap key.

The nut has very big moment of an otvorachivaniye. If necessary it is possible to strike blow to a key with a hammer.

5. Remove a washer.
6. Remove a support with a sealing ring and a washer.
7. Remove the top plate of a spring with laying 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 integrity of a covering. If necessary eliminate damages.
2. Check 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 amortization 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 rounds a new being self-stopped nut.
6. Slowly unclench a spring so that it thus adjoined to plates. Watch the correct provision of the bottom cup of a spring (rectangular grooves).
7. Tighten a nut of fastening the moment of 65 Nanometers (at an internal shestigrannik on a rod the moment of 45 Nanometers). Hold from a provorachivaniye a rod. Repair trucks apply BMW-312210 or HAZET 2593-* head to observance of the moment of an inhaling (* - the size of a key).
8. Completely unclench a spring and remove the adaptation for compression.
9. Establish an amortization rack.
