3.4.5. Nave of a back wheel

Fig. 3.150. Nave of a back wheel

ATTENTION On cars with ABS system remove the sensor of frequency of rotation of a back wheel. Be careful at removal of the sensor of frequency of rotation of a wheel from an arm not to damage a polar tip of the sensor about teeths of its rotor or other details.

Remove a support of a disk brake and suspend it aside by means of a wire.

Remove a brake disk.

Uncover naves, unscrew a nut of fastening of the bearing of a nave and remove a lock washer.

Fig. 3.151. Nave removal assembled

Remove a nave assembled (fig. 3.151).

ATTENTION The knot of the bearing of a nave of a back wheel is not subject to dismantle. Be careful not to scratch or to damage teeths of a rotor of the sensor of frequency of rotation of a wheel. Do not drop a rotor. Formation of chips on teeths of a rotor of the sensor, will lead to deformation of a rotor and, as a result, to impossibility of the correct determination of frequency of rotation of a wheel and violation of work of ABS system as a whole.

Check an epiploon on lack of cracks or damages.

Check the bearing of a nave of a wheel on lack of wear or damages.

Check lack of chips on teeths of a rotor of the sensor of frequency of rotation of a wheel.

Check a fist of a back wheel on lack of cracks.

Fig. 3.152. Zachekanivaniye of a flange nut

After an inhaling of a flange nut зачеканьте nut edge on dredging of a shaft of a fist of a back wheel (fig. 3.152).

ATTENTION Replace a flange nut new after removal.

Fig. 3.153. Sensor of frequency of rotation of a wheel

For cars with ABS system establish the sensor of frequency of rotation of a back wheel. For this purpose insert flat щуп into a gap between a polar tip of the sensor of frequency of rotation of a wheel and tooth of a rotor of the sensor. Fix the sensor so that the gap between a polar tip of the sensor and rotor tooth (on all circle) was in limits of nominal rate (fig. 3.153).

Nominal gap size: 0,2–1,3 mm.

Establish a cover of a nave of a wheel.
