4.2.11.5.3. The fan
THE GENERAL DATA

Муфта the cooling fan

1 – a contact brush,
2 – a contact ring,
3 – приводной a belt,
4 – the coil,
5 – blades of the fan,
6 – a bolt and a nut of fastening of blades of the fan,
7 – a central nut,
8 – an axis,
9 – the bearing,
10 – an adjusting bolt,
11 – an air backlash,
12 – grounding,
13 – bearings,
14 – a cover of a drive of the mechanism timing

The drive of the fan of cooling consists of two important parts – electromagnetic and frictional муфт. Electromagnetic муфта it is put in action клиновым by a belt and rotates on an axis which leans against two ball bearings, established in inflow of a cover of a drive of the mechanism timing. On the forward end of this axis the ball bearing on which freely rotates frictional муфта with fan blades is established. Between electromagnetic and frictional муфтами there is an air backlash if the temperature of the engine does not exceed 71 S.Kogda temperature of a cooling liquid rises above 85 With, the gauge established on a radiator, submits pressure on a coal contact brush and, through a contact ring, on the electromagnetic coil Under the influence of a magnetic field, frictional муфта is drawn to electromagnetic, and fan blades start to rotate with speed of rotation of a pulley. At reduction of temperature of a cooling liquid, the electromagnet is disconnected, the backlash is restored also fan blades are slowed down, rotating only under the influence of air and inertia stream.

For normal work муфты the tension of a belt of a drive should be in norm, the electric gauge is serviceable, the coal brush is not worn out, and a contact ring the pure. A backlash between the fan and the plug муфты – 0,5 mm on the cold engine. Before backlash check it is necessary to remove fan blades, having turned away a fastening nut. Measurements are made щупом in several points on a circle. For adjustment carrying out it is necessary to weaken counternuts of adjusting bolts and, rotating them, to establish a demanded backlash.

Removal and installation муфты the fan

PERFORMANCE ORDER
1. To merge cooling liquid from system.
2. To disconnect branch pipes from a radiator and to remove a radiator.
3. To remove приводной a fan belt.
4. To fix a pulley and to unscrew the central nut of an axis of the fan.
5. A back support of the engine.
6. Easy blows киянки on a pulley and муфте to remove electromagnetic муфту.
7. To uncover a mechanism drive timing, to remove a lock spring ring and to take an axis of the fan with bearings.
8. It is established муфта in sequence of return to removal.
