Replacement клинового and поликлинового a belt

Knots of a belt drive at the four-cylinder engine with the removed face-to-face part of the car

1 – the compressor of climatic installation;
2 – a tension roller;
3 – a belt pulley коленвала;
4 – a tension roller;

5 – the generator;
6 – a nave вязкостного the fan;
7 – a belt pulley сервонасоса;
8 – an intermediate roller.


To dismantle клиновой a belt (2) water pumps, it is necessary to unscrew a pulley (1) water pumps.

Drawing and in a photo the same theme: a tension поликлинового a belt in the six-cylinder engine. In drawing the tension roller is fixed by a bolt with шестигранной a head and can lean back накидным a key. In a photo bolt TORX which for откидывания a roller nozzle TORX (2) c is put on by a suitable unprofitable key is visible. A pin (1; here the punch) is inserted into the aperture provided for this purpose in the tension device, at the expense of it the tension device is fixed in the given position.

Audi provides preventive replacement поликлинового a belt of the six-cylinder engine and small клинового a belt of the water pump of the four-cylinder engine through each 120 000 km of run. The big belt of the six-cylinder engine, being a drive of many auxiliary units, is exposed большей to loading, клиновой the belt of the four-cylinder engine is a drive of the water pump having crucial importance for a life of the engine (the text see more low).

Dismantle клинового and поликлинового a belt from the four-cylinder engine

Here dismantle (replacement) of all drivers belts is described. Therefore this description it is possible to be used for other cases. The sequence of dismantling, concerns dismantle of all belts, but is not necessary at replacement of one belt.

Through 120 000 km of run Audi demands replacement only short клинового a belt, but because of great volume of work replacement of all belts is offered.

 PERFORMANCE ORDER

  1. First of all, unscrew a face-to-face part of the car and result it in position for service (the head of the Detail of a body).
  2. Note a rotation direction клиноребристого a belt a chalk or a felt-tip pen (for installation).
  3. Poliklinovoj belt for the compressor of climatic installation: ослабьте both fixing bolts of the tension device of a belt
  4. At the expense of it the tension клиноребристого a belt is weakened, and it can be removed
  5. Poliklinovoj belt for сервонасоса, the generator and вязкостного the fan: establish рожковый a key on the tension device and cast away it to the right.
  6. Fix the tension device. For this purpose insert a pin (for example, a suitable drill) into the aperture intended for it.
  7. Remove поликлиновой a belt between сервонасосом and the generator from outside the generator.
  8. Again raise a key the tension device and remove a pin.
  9. Block a belt pulley вязкостного the fan bolt М5 x 60 mm and unscrew a fixing bolt (internal шестигранник 8 mm behind).
  10. Remove вязкостный the fan and клиноребристый a belt.
  11. Klinovoj belt of the water pump: ослабьте three bolts of a belt pulley on the water pump. For this purpose block a pin a belt pulley сервонасоса.
  12. Remove a belt pulley and a belt.
  13. About installation and a tension of belts see in following section.

 Council: New клиновой the belt in no event cannot be pulled on belt pulleys by means of a screw-driver since breaks arising at the expense of it would program in advance the following defect of a belt.

Installation клинового and поликлинового a belt on the four-cylinder engine

 PERFORMANCE ORDER

  1. At installation were in the use клиноребристого a belt consider preliminary designated direction of rotation.
  2. Klinovoj belt of the water pump: in stages tighten bolts of a belt pulley of the water pump with imposed клиновым a belt. Thus constantly turn a belt pulley that клиновой a belt has not clamped between half of belt pulleys.
  3. Only when клиновой the belt moves from an outer side in correct position, tighten bolts on 25 nanometers.
  4. Poliklinovoj belt of the compressor of climatic installation: fixing bolts of a tension roller are still weakened.
  5. Check up, whether the console with a tension roller easily moves.
  6. Establish динамометрический a key on шестигранник consoles of a tension roller and tighten on 25 nanometers – the belt tension will be correct.
  7. Tighten fixing bolts (20 nanometers).
  8. Poliklinovoj belt сервонасоса, the generator and вязкостного the fan: establish on the tension device рожковый a key and cast away it to the right.
  9. Fix the tension device.
  10. Impose поликлиновой a belt; watch thus correct landing of a belt to belt pulleys.
  11. At imposed поликлиновом a belt again lift the tension device a key and remove a pin.
  12. The moment of an inhaling for вязкостного the fan: 45 nanometers.

Dismantle and installation поликлинового a belt from the six-cylinder engine

 PERFORMANCE ORDER

  1. Dismantle an engine cover (the head Engines).
  2. Dismantle a cover клиноребристого a belt.
  3. Cars with вязкостным the fan: dismantle вязкостный the fan (the head cooling System).
  4. Establish unprofitable key SW 17 on шестигранник a tension roller.
  5. In cars without шестигранника: wring out a cover of a tension roller and establish on the central bolt of a tension roller key TORX-T40.
  6. Cast away to the right the tension device.
  7. Fix the tension device. For this purpose insert a pin (for example, a suitable drill) into the aperture provided for this purpose.
  8. Note a chalk or a felt-tip pen a rotation direction on a belt.
  9. Remove поликлиновой a belt.
  10. At installation: in the beginning impose клиноребристый a belt on a belt pulley коленвала and a directing roller, then on a tension roller.
  11. Again lift a key the tension device and remove a pin.
  12. Establish covers.
