Removal and installation of an amortisation rack and the case of the wheel bearing

THE GENERAL DATA

Amortisation rack and the case of the wheel bearing

1 – a nut with a fillet, 60 Н•м. Self-stopped, it is necessary to replace necessarily.
2 – a cup
3 – an amortisation rack. For spring or shock-absorber replacement it acts in film and established completely.
4 – the screw with internal шестигранником, 8 Н•м
5 – gauge ABS
6 – a nut, 45 Н•м. Self-stopped, it is necessary to replace necessarily.
7 – a spherical support
8 – the case of the wheel bearing
9 – a cover
10 – a bolt, 7 Н•м
11 – the wheel bearing
12 – a lock ring
Take out together with the help of usual nippers. At installation watch correct position.
13 – a nave. With a rotor for gauge ABS
14 – a bolt. Necessarily replace.
15 – a nut, 50 Н•м + 90 (1/4 turns). Self-stopped, it is necessary to replace necessarily.

REMOVAL

PERFORMANCE ORDER
1. Remove a wheel cap. At wheels from easy alloys the cap acts in film by means of demountable hooks from the complete set of the onboard tool.
2. Turn on двенадцатигранную a nut of fastening of a shaft of a drive to a nave.
ATTENTION

At отворачивании a bolt the car should stand on wheels. There is a danger of accident owing to the big moment отворачивания!


3. Mark a paint position of a corresponding forward wheel concerning a nave. It will allow to establish at assemblage отбалансированное a wheel in its former position. Loosen the bolts of fastening of a wheel at the car standing on the earth. Lift a forward part of the car, put it on supports and remove a forward wheel.
ATTENTION

Operation of lifting and car installation on supports is connected with danger! Therefore before operation carrying out familiarise with subsection of Poddomkrachivanie of the car.


4. Mark a felt-tip pen or чертилкой position of bolts of fastening – 1 spherical support. Otherwise at assemblage it is necessary to measure a forward suspension bracket and to adjust it. Turn out bolts – 1.
5. Disconnect by means of a stripper a shaft of a drive from a nave.
ATTENTION

Do not disconnect a brake hose from a brake support. Otherwise after assemblage it is necessary to remove systems from system air.


6. Depending on model various variants of a design of a forward brake can be established. A support FS - III: Remove covers – 2 and disconnect a support. A support casing suspend on a wire to the chassis. A support FN - 3: Turn away bolts with edges from a support casing. At installation it is necessary to replace them with the new. Remove a support, address to subsection Removal and installation of a brake disk/support.
7. Turn away the screw with crosswise шлицем and remove a brake disk.
8. Turn away a nut of fastening of the hinge of steering draught till the end of a carving. It carries out a role of a support for a stripper.
9. Wring out a stripper (), for example, Hazet 779 pin of the hinge of steering draught from the lever.
10. Disconnect the tip – 1 gauge of number of turns ABS.
11. Remove a wire of gauge ABS from the holder (marksman).
12. Turn away a nut of fastening of an amortisation rack tool AUDI 3186, keeping thus a screw-driver under internal шестигранник 7 mm for a rod from проворачивания. If the specified tool available is not present, turn away a nut by means of cranked накидного a key. There is special tool Hazet № 2593 21.
13. Take out an amortisation rack and the case of the bearing of a wheel downwards through a wheel casing.
14. Separate the case of the bearing of a wheel and an amortisation rack. For this purpose turn away a bolt of fastening of an amortisation rack to the case of the bearing of a wheel.
15. Take out an amortisation rack upwards from the case of the bearing of a wheel. If it is hardly taken out, for simplification of dismantle expand шлиц in the case of the bearing of a wheel with the tool AUDI - 3424 or any other suitable tool a little.
INSTALLATION
16. Put on the case of the bearing of a wheel an amortisation rack so that apertures at a pipe of the shock-absorber and the bearing case coincided.
17. Insert into the bearing case / an amortisation rack a new bolt. The head of a bolt at the established amortisation rack is ahead in a movement direction. Screw a new self-stopped nut and tighten its moment 50 Н•м, then a rigid key tighten on 90 (1/4 turns).
18. Before installation of an amortisation rack grease a rack support with assembly oil G 294 421 F1 (arrows on an illustration).
19. Insert an amortisation rack and fix from above a new nut the moment 60 Н•м, keeping it from проворачивания a key under internal шестигранник 7 mm.
ATTENTION

To establish динамометрический a key, as the tool it is possible to apply AUDI - 3186 or HAZET 2593 21 complete with 2100 07 to deduction from проворачивания.


20. Clear teeths and a carving of a shaft of a drive and a nave a brush of corrosion and other pollution.
21. Cover двенадцатигранную a nut and teeths of the external hinge on a drive shaft with pure impellent oil. Enter as it is possible more deeply the external hinge in nave teeths.
22. Establish a brake disk/support, address to subsection Removal and installation of a brake disk/support.
ATTENTION

If pipelines of brake system were opened, it is necessary to remove air from last, address to subsection Removal of air from brake system.


23. Join a socket of the gauge of number of turns ABS, lay a wire in the holder on an amortisation rack.
24. Fix a spherical support on the lever. Establish fastening bolts in oval apertures so that earlier put marks have coincided. Tighten bolts the moment 20 Н•м then tighten a rigid key on a corner 90 (1/4 turns).
ATTENTION

At installation in the new lever establish fastening bolts in average position and tighten. In summary measure disorder, address to Section 15.


25. Insert steering draught into the pendular lever on the case of the bearing of a wheel and tighten a new self-stopped nut the moment 45 Н•м.
26. Screw new двенадцатигранную a nut of fastening of a shaft of a drive to a nave and tighten the moment 50 Н•мv. Thus ask the assistant to press a brake that the nave was not turned.
27. становите into place a forward wheel so that the marks put at removal have coincided. Preliminary grease with a thin layer подшипниковой greasings aligning belt of a disk of a wheel on a nave. Bolts of fastening of a wheel do not grease. Rusty bolts replace. Wrap bolts. Lower the car on wheels and tighten bolts a cross - crosswise the moment
120 Н•м.
28. Lower the car on wheels and fix a drive shaft to a nave, address to subsection Removal and installation of power shafts.
