Removal and installation карданного a shaft

 REMOVAL

1. Lift and establish the car on supports.
2. Remove system of release of the fulfilled gases.

3. Turn away bolts of fastening and remove the heat-shielding screen (1), (2) from the bottom.

4. Turn away bolts of fastening and remove a flange карданного the hinge at РКПП. Thus the shaft is necessary for keeping from проворачивания a usual tape clip.

5. Turn away a fastening nut карданного a shaft at a flange of the main transfer of the back bridge.

6. Wring out in grooves a screw-driver the hinge of equal angular speeds at a flange.

Do not suppose displacement карданного a shaft in the hinge. It can lead смятию a protective casing of the hinge of equal angular speeds.

7. Clamp the central bearing and turn away a nut.

8. Lower карданный a shaft at the central bearing downwards and take out it from an aligning pin at РКПП.

Close the hinge of equal angular speeds a polyethylene bag for protection against pollution.

Installation

At vibration and the noise, going from карданного a shaft, it it is necessary to balance.

Kardannyj shaft отбалансирован on all length. To replace it it is possible only in the complete set.


 INSTALLATION

1. Replace a shaft flange if it is worn out. For this purpose turn away bolts (arrows on an accompanying illustration). Establish a new flange so that the arrows put on circles, specified in a direction of spokes of a flange.

2. Before installation check up aligning element (4) on a flange карданного a shaft. If necessary grease an element with plastic greasing “Molykote Longtherm 2”. The damaged aligning element replace with the new.

3. Pull together the hinge of equal angular speeds (1) against the stop. Enter greasing into the hinge if greasings are not present. To this purpose apply only the greasing recommended by firm BMW.

4. Replace a sealing ring (2). Preliminary wipe greasing on sealing surfaces of the hinge and приводного a flange spirit.
5. Put on карданный a shaft with the put forward hinge a flange of the main transfer of the back bridge.

It is not necessary to shift during assemblage the hinge of equal angular speeds, since. Thus greasing can squeeze out a sealing ring and the hinge becomes not tight.

Tighten a shaft to a flange of the main transfer. Establish new self-stopped nuts and tighten their moment of 70 Nanometers.
6. Tighten bolts of fastening of a flange. The moment of an inhaling of bolts М8 of 45 Nanometers, М10 - 70 Nanometers, М12 - 80 Nanometers
7. Tighten bolts of fastening of the central bearing the moment of 22 Nanometers.
8. Fix the heat-shielding screen.
9. Establish system of release of the fulfilled gases, address to Section of the Rule of observance of cleanliness At work with fuel system.
10. Lower the car on wheels.
