Removal and installation of power shafts of wheels
|
At damage external, located from a wheel, the hinge of equal angular speeds the corresponding shaft should be replaced completely. |
Removal
|
1. Tighten the parking brake.
|
At an otvorachivaniye of a nut of fastening of a wheel the car should stand wheels on the earth. Include transfer, tighten a brake. Big moment of an otvorachivaniye. There is a danger of accident! |
|
2. Unbend a screw-driver a fillet of a nut of fastening of a wheel from a shaft groove. A nut unscrew a dvenadtsatigranny head. |
3. Release the parking brake. 4. Mark with paint the provision of back wheels concerning a nave. It will allow to establish at assembly the balanced wheels in their former situation. Weaken bolts of fastening of wheels before a car poddomkrachivaniye. Lift a back part of the car, put it on supports and remove back wheels. 5. Disconnect a back support and fix it a wire to a body, address to the Section Removal and installation of a back support.
|
Do not disconnect a brake hose. Otherwise after installation it is necessary to delete air from brake system. |
6. Remove the connecting bar going to the stabilizer. 7. Disconnect the sensor of number of turns from a fist. 8. Disconnect steering draft from a fist. 9. Cast away a fist outside and at the same time squeeze out a power shaft from a flange.
|
Thus do not draw a brake cable. Do not damage protective covers and a gear ring of the sensor of turns. |
10. Cast away back a fist and fix a wire.
|
11. If the power shaft densely sits in a flange, squeeze out it a usual stripper.
|
Unlike represented on an accompanying illustration the support is removed. |
|
|
|
Power shaft of execution 1
|
|
1. Take out a power shaft (1) with the internal hinge (2) of the main transfer (3).
|
Thus do not damage a sealing ring in the main transfer. |
|
If necessary disconnect a power shaft in hammer blows on an external ring of the hinge and by means of the corresponding drift. |
|
2. Visually check damages of a cuff to the main transfer, if necessary replace.
|
For this purpose squeeze out a screw-driver a cuff. Before installation grease a working edge of a cuff with universal oil for gipoidny SAE 85W-90 broadcasts. Press a cuff by means of the corresponding drift. |
|
|
Power shaft of execution 2
|
|
1. Turn out 6 screws of fastening of Torx and disconnect a power shaft (1) from a connecting flange (2). (3) – main transfer.
|
Watch the correct provision of a face head in Torx screw head. If necessary clear a Torx screw profile. |
|
|
2. Shift a power shaft, then incline down and remove.
|
Watch that at removal of a shaft the locking cover did not act in film. |
|
3. Check a protective cover and a locking cover on tightness and existence of damages, if necessary repair.
|
At the removed power shaft the car should not stand on wheels with full loading and should not move, since in the absence of an axial tightness bodies of a kacheniye of the bearing of a wheel can be damaged. |
|
|
Installation
|
|
If at removal of a power shaft the application of the big effort necessary for expression of a nave of a wheel is demanded, it is recommended to cut on the end of a shaft female thread М8 depth of 20 mm. It is possible to screw the tool in this opening for dismantle. Depending on execution of a power shaft in it there can be an opening in diameter of 6.8 mm that corresponds to internal diameter of carving М8. Before installation clear a profile шлицов of the greasing remains. |
Power shaft of execution 1: Insert a shaft into the main transfer so that the lock ring was distinctly fixed.
|
Thus establish horizontally the hinge case not to warp shlitsevy a shaft at installation. The case of the hinge should be located densely to a case of the main transfer. |
|
|
Power shaft of execution 2
|
1. Clear a surface between a connecting flange and a locking cover. 2. Establish a shaft at a connecting flange. 3. Slightly grease a carving and a basic surface of a head of new Torx screws. 4. Establish a new washer and screw Torx screws. Screws tighten cross-wise the moment 70Нм. 5. Fix new being self-stopped nuts steering draft and bars.
|
At an inhaling of nuts the power shaft is necessary for bringing into horizontal situation. For this purpose it is necessary to raise the holder of a wheel a jack. The moments of an inhaling are given in Specifications. |
6. Fix the sensor of number of turns at a fist the moment 8Нм. 7. Insert connecting draft of the stabilizer and fix it the moment 40Нм. 8. Establish a support and fix it the moment 55Нм, address to the Section Removal and installation of a back support. 9. Establish into place back wheels so that the marks put at removal coincided. Previously grease with a thin layer of bearing greasing 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 cross-wise the moment 110Нм. 10. Tighten the parking brake. 11. Screw a new dvenadtsatigranny nut with a fillet and tighten the moment 220Нм.
|
Thus the car should stand wheels on the earth. It is necessary to replace a nut with the new surely. At an inhaling include transfer and tighten the parking brake. |
|
12. Fix a nut for what with a drift hammer a fillet into a groove so that between a groove and a fillet there was no gap. |
13. Release the parking brake. 14. Check oil level in the main transfer. |
