4.7. Removal and installation of the hug bearing of a forward wheel

ATTENTION
The alarm disk for the sensor of speed of rotation of a wheel is built in the bearing, take measures not to damage a disk (if it is) at installation of the bearing.

Removal
Remove a rotary fist.

Fig. 4.18. Vypressovka of a nave from the bearing: 1 – stripper


By means of a press to a vypressuyta a nave from the bearing, having established on it a mandrel with an outer diameter of 36,5 mm, and under a rotary fist – a stripper (fig. 4.18).

Fig. 4.19. Vypressovka from a nave of internal kolets of the bearing: 1 – stripper


Vypressuyte from a nave an internal ring of the bearing by means of a stripper (fig. 4.19).
Establish captures of a stripper in a flute of an internal ring of the hug bearing and remove it.
Remove a lock ring of the bearing.

Fig. 4.20. Removal of an external ring of the bearing


Remove an external ring of the bearing, having rested a piece of a pipe with an outer diameter of 65 mm (fig. 4.20) against an internal ring.

ATTENTION
Do not use as a support the holder of the sensor (if it is established).

Installation

ATTENTION
Do not move the car with unspecified to naves of wheels and the power shafts which are not tightened the required moment as it can lead to destruction of bearings of naves of wheels and to damage of gear alarm disk ABS.

ATTENTION
Surely check a condition of a surface of a nave and an opening of a rotary fist before installation of the bearing. Replace the injured rotary fist.

Clear:
– the internal and external surfaces of the new bearing adjoining to a rotary fist and to a nave;
– the surfaces of a rotary fist adjoining to the new bearing;
– the nave surfaces adjoining to the new bearing.
Establish the holder of the sensor.
If the car is equipped with the sensor of speed of rotation of a wheel, arrange the holder of the sensor at an angle X

Fig. 4.21. Installation of the holder of the sensor of speed of rotation of a wheel

35 ° ±5 ° from a vertical axis of a rotary fist: this situation corresponds to the center of a seat (fig. 4.21).

Fig. 4.22. Primary press fitting of the bearing


For a press fitting of the bearing establish a mandrel with an outer diameter of 70 mm on an external ring (fig. 4.22).

ATTENTION
Not to damage the bearing, do not lean on an internal ring as the effort of a press fitting of the bearing is very high.

Establish a lock ring of the bearing.

Fig. 4.23. Vtorvichny press fitting of the bearing


For a press fitting of the bearing establish a mandrel with an outer diameter of 50 mm on an internal ring (fig. 4.23).
Install a rotary fist assembled with a nave and the bearing on the car.
Tighten the required moment:
– bolt of fastening of a spherical support of the lever of a suspension bracket (62 N · l);
– nut of fastening of a finger of the spherical hinge of a tip of steering draft (37 N of m);
– nave nut (280 N · l);
– bolts of fastening of a damping rack to a rotary fist (105 N · l);
– screws of fastening of a brake disk (140 N · l);
– bolt of fastening of a guide of blocks (105 N · l);
– bolts of fastening of wheels (110 N · м).
