| 1. Designate paint the provision of forward wheels in relation to a nave. Thanks to it the balanced wheel after removal comes back to the same situation. Release bolts of wheels before car lifting. Put the car in front on supports and remove forward wheels. |
|
|
2. Screw a brake disk on a nave a wheel bolt (43а), having inserted it into an opening located opposite to an adjusting bolt (9k). |
| 3. Carefully a screw-driver wring out brake shoes from a brake disk. |
|
4. Remove a nave cap (9е) by means of a stripper (023) or bring down it a rubber hammer. |
| |
5. Check a gap by a pulling and flange cave-in by hands. Before each attempt turn a nave a little. |
6. The axial gap is measured in workshops by means of the adaptation having as the sensor the hour indicator of small movings. The sensor is established with deepening of a measuring rod of 2 mm. The preset value of the correct gap makes 0,01–0,02 mm.
Prevention
In the course of separate measurement, submitting a flange there and back on an axis, it is impossible to turn a nave.

|
7. Release a bolt with an internal shestigrannik (9i). |
| 8. Screw up a cutting nut at simultaneous rotation of a nave until it cannot be turned more. Then release a nut on 1/3 turns and in blow of a plastic hammer on an axis (5а) weaken a tightness. Measure a gap. |
| 9. If necessary repeat gap installation. The Mercedes firm orders gap installation by means of the hour indicator. However in practice (when there is no the indicator) the gap is considered correct if the washer under a cutting nut with some effort can be displaced there-here by means of a screw-driver. If the washer does not manage to be got moving forward, it is necessary to wring out or release a cutting nut. |
| 10. Tighten a bolt with an internal shestigrannik on a cutting nut with the moment of 8 N of m and once again check a gap of bearings. |
|
11. A nave cap to edge of an otbortovka (shooter) fill with high-temperature greasing for bearings in number of about 15 g. |
12. Put into place a nave cap by means of the special adaptation 025 or fill a rubber hammer.
Prevention
The beaten cap surely replace, as through joint thinnesses moisture owing to what it quickly collapses gets into the bearing.
|
| 13. Unscrew a wheel bolt on a brake disk. |
| 14. Put on a wheel, observing marking of its former situation earlier put with paint. Screw a wheel. Lower the car on wheels and in a crosswise order tighten wheel bolts with the moment of 110 N of m. |
| 15. Repeatedly понажимайте on a brake pedal that brake shoes rose into position. |
