Power shafts

Removal and installation of power shafts

THE GENERAL DATA

Power shaft with the hinge of equal angular speeds

1 – a lock ring. Necessarily replace.
2 – a sealing lining. Necessarily replace. Remove a protective film and paste to the hinge.
3 – the internal hinge of equal angular speeds, 100 mm
4 – a spring тарельчатая. On internal diameter has teeths. The big diameter adjoins to the hinge.
5 – a protective cover. For the hinge of equal angular speeds of 100 mm. A cover inside grease with hermetic AUDI źD3╗.
6 – a shaft. For the hinge of equal angular speeds of 100 mm.
7 collar. Necessarily replace.
8 – a protective cover. For the hinge of equal angular speeds of 90 mm.
9 – a collar
10 – a spring тарельчатая. The big diameter (the concave party) adjoins to a persistent ring.
11 – a persistent ring
12 – a lock ring
13 – the hinge external, 90 mm.
14 hinge internal, 94 mm.
15 – a protective cover. For the hinge
94 mm.
16 – a protective cover. For the hinge of 94 mm and 100 mm, only a left-hand side (except TDI).
17 – a collar
18 – a shaft. Only for the hinge of 94 mm.
19 – a protective cover. For the hinge
81 mm.
20 – the hinge external, 81 mm. Removal: strong blow of a hammer from easy metal.

Power shaft with триподным the hinge. Cars with АТ

1 – the hinge external. Replace only in the complete set. For installation use a hammer from plastic. Насаживается before fixing of a lock ring.
2 – a lock ring. Insert into a shaft groove.
3 – a remote ring (plastic)
4 – a spring тарельчатая. Big (the concave party) adjoins to a persistent ring.
5 – a collar. Necessarily replace.
6 – a protective cover. For the hinge of 90 mm. Before installation a small collar of a protective cover raise and fill a cover with air.
7 – a collar
8 – a shaft left. With internal hinge Tripode. In the presence of damages it is necessary to replace the internal hinge and a shaft.
9 – the screw with an internal teeth, 45 Н•м
10 – the hinge right. With hinge Tripode. In the presence of damages it is necessary to replace the internal hinge and a shaft.


ATTENTION

After отворачивания двенадцатигранной nuts (an axis nut) by which the power shaft is fixed to a nave, it is not necessary to put the car with a total load on wheels and to shift it. In the absence of axial поджатия the wheel bearing can be damaged. If necessary instead of a power shaft establish the external hinge and fix its moment 50 Н•м.


REMOVAL

PERFORMANCE ORDER
1. Remove a decorative cap of a wheel, at wheels from easy metal remove caps demountable hooks from the complete set of the onboard tool.
2. Loosen the двенадцатигранную a nut of a nave of a wheel at a drive shaft, without turning on it.
ATTENTION

At отворачивании nuts of fastening of a shaft of a drive the car should stand whenever possible wheels on the earth. If the car is lifted, put a key so that the effort at отворачивании operated vertically downwards. Otherwise the car can slide off sideways supports. The big moment отворачивания. Danger of accident!


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 on 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 position of bolts-1 spherical support or lead round them чертилкой. Otherwise at the subsequent installation it will be necessary to spend measurement and adjustment of a forward suspension bracket. Turn out bolts-1.
5. If the drive shaft manually is not taken out from a nave, remove a shaft by means of a stripper. HUNDRED AUDI apply for this purpose stripper AUDI-3283.

ATTENTION

Let's to a shaft hang, differently the internal hinge can be damaged as a result of an excess.


6. Turn out screws with an internal polyhedron for a drive shaft on a transmission flange. The insert under an internal polyhedron, for example, HAZET 990 Lg-8 is for this purpose necessary.
7. Cars with РКПП: Incline an amortisation rack outside and take out a shaft of a drive from the case of the bearing of a wheel.
Cars with АТ:
8. Turn away fastening bolts (arrows on an illustration) support АТ to a unit beam.
9. Insert mount between a beam of the unit and the block of cylinders and take away the block in a movement direction. Simultaneously, hinge Tripode of a shaft of a drive can be taken out.
INSTALLATION
10. Clear a brush teeths and a carving of a shaft of a drive and a nave of a rust and other pollution.
11. Fix a shaft on a check point. Tighten screws with an internal polyhedron cross-wise. The moment of an inhaling of a check point (the hinge of equal angular speeds): 40 Н m; АТ (hinge Tripode): 45 Н m.
12. Grease an adjoining surface двенадцатигранной nuts and teeths of the external hinge with pure impellent oil. Enter the external hinge into nave teeths how much it probably.
13. Fix шаровый the hinge on the lever. Establish fastening bolts in oval apertures so that earlier put marks have coincided. Tighten bolts the moment 20 Н m 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 subsection Corners of installation of forward wheels.


14. Establish the internal hinge of a shaft of a drive and tighten screws with an internal polyhedron.

The inhaling moments:

М8 40 Н m
М10 80 Н m
15. Cars with АТ: Tighten bolts of fastening of a support of a check point to a beam of the unit the moment 25 Н m.
16. Enter the external hinge against the stop into the wheel bearing.
17. Tighten двенадцатигранную a nut the moment 300 Н m and then again turn away it on Ѕ a turn.
18. Tighten двенадцатигранную a nut the moment 50 Н•м, then tighten a rigid key on 45 ░ (1/4 turns).
ATTENTION

Angular washer HAZET is necessary for an inhaling on a certain corner 6690. If such washer available is not present, двенадцатигранная the nut can be tightened as follows.


19. Lower the car so that wheels concerned the earths.
20. Tighten двенадцатигранную a nut the moment 300 Н m and again turn away it on Ѕ a turn.
21. Tighten двенадцатигранную a nut the moment 50 Н m.
22. Mark one side of a nut (the marksman And on an illustration). The second marks (marksman) put on a nave edge through the following edge. Instructions: the Distance from one side to another makes 45 ░.
23. Tighten двенадцатигранную a nut a key so that both marks have coincided.
