2.7.5. Removal and installation поликлинового a belt

THE GENERAL DATA

Arrangement of belts on four-cylinder petrol engines

1 – the device of a tension  of a belt, 2 – the generator, 3 – the fan, 4 – the water pump, 5 – the pump of the amplifier of a steering, 6 – a belt of the water pump,

7 – a belt of the amplifier of a steering of the fan and the generator, 8 – гаситель fluctuations, 9 – the mechanism of a tension of a belt of the compressor of the conditioner, 10 – a belt of the compressor of the conditioner, 11 – the conditioner compressor

The poliklinovoj belt is as a matter of fact, a flat belt, on the one hand which there are ribs. The poliklinovoj belt carries out a drive of the generator, the pump of the amplifier of a steering, вентилято ра a radiator, the compressor of the conditioner and the water pump depending on engine updating. On models with four-cylinder engines with a central air of air for a drive of the compressor of the conditioner the separate belt is used.

Removal

PERFORMANCE ORDER

1. Remove поликлиновые belts of a drive of the pump of the amplifier of a steering, the generator and the radiator fan. 2. If the belt is repeatedly established, using a marker or a paint, an arrow note a direction of its rotation. 3. Ослабьте screws of fastening of the mechanism of a tension поликлинового a belt and after tension easing поликлинового a belt remove it from pulleys.

Installation

PERFORMANCE ORDER

1. Establish поликлиновой a belt on pulleys. At repeated installation поликлинового a belt establish it according to earlier put arrow. 2. Check up correctness of an arrangement поликлинового a belt on pulleys. 3. Establish динамометрический a key on an arm of a tension roller поликлинового a belt and turn its moment of 25 Nanometers and in this position tighten bolts of fastening of the mechanism of a tension (). 4. Establish a belt of a drive of the pump of the amplifier of a steering of the generator and the radiator fan.

BELT OF THE DRIVE OF THE PUMP OF THE AMPLIFIER OF THE STEERING, THE GENERATOR AND THE RADIATOR FAN ON FOUR-CYLINDER PETROL ENGINES

Removal

PERFORMANCE ORDER

1. If the belt is repeatedly established, using a marker or a paint, note a direction of rotation of a belt. 2. Move forward a belt casing. 3. For easing of a tension of a belt, using a wrench, turn the tension mechanism clockwise and fix its steel core in diameter of 5 mm. 4. Remove a belt from pulleys.

Installation

PERFORMANCE ORDER

1. Check up that all pulleys are fixed reliably, otherwise tighten bolts of fastening of pulleys. 2. Establish belts on engine pulleys. At repeated installation of belts establish them according to earlier put arrows. 3. For a wrench press the mechanism of a tension of a belt in a direction of an hour hand and take the steel core fixing the mechanism of a tension. Slowly release the mechanism of a tension of a belt, thus there will be an automatic tension of a belt. 4. Establish into place a belt casing. 5. Start the engine and check up work of belts.

BELT OF THE DRIVE OF THE PUMP OF THE AMPLIFIER OF THE STEERING OF THE GENERATOR OF THE WATER PUMP AND THE RADIATOR FAN ON DIESEL ENGINES

---

The prevention

Operations on removal and belt installation are similar to operations on removal and installation of a belt for the four-cylinder petrol engine. In this subsection operations, characteristic for diesel engines are resulted only.

---

PERFORMANCE ORDER

1. A wrench for a bolt head turn a tension roller counter-clockwise and remove a belt. The bolt has the left carving, therefore at its turn counter-clockwise it will not be unscrewed.

Installation

PERFORMANCE ORDER

Wrench for a bolt head turn a tension roller of a belt clockwise and establish a belt on pulleys. Slowly release a tension roller, thus a belt tension it will be adjusted automatically.

THE FIVE-CYLINDER ENGINE

Removal

PERFORMANCE ORDER

1. Unscrew from a nave four bolts, крепящие the fan of a radiator and remove it. 2. A 15-millimetric face wrench turn a bolt of fastening of the mechanism of a tension counter-clockwise and remove a belt.

Installation

PERFORMANCE ORDER

Using накидной a wrench, turn a tension roller clockwise and dress приводной a belt. Slowly release a tension roller, thus there will be an automatic tension приводного a belt.

THE SIX-CYLINDER ENGINE

Arrangement auxiliary приводного a belt on the six-cylinder engine

1 – the generator, 2 – a belt, 3 – the pump of the amplifier of a steering 4 – the fan of a radiator, 5 – the compressor of the conditioner, 6 – a cranked shaft, 7 – a tension roller of a belt

---

The prevention

On cars without air central air auxiliary приводной the belt is established from a pulley 6 on a pulley 4.

---

Removal

PERFORMANCE ORDER

1. Keeping a pulley of the fan of a radiator from проворачивания, special key VW-3212 a usual key unscrew a bolt of fastening of a pulley. Keep in mind that the bolt has the left carving, therefore for its unscrewing, it is necessary for rotating clockwise. 2. A wrench turn the mechanism of a tension of a belt clockwise before combination of apertures. Fix the tension mechanism in this position, having inserted into an aperture a steel core in diameter of 5 mm.

Installation

PERFORMANCE ORDER

1. Dress приводной a belt in a direction counter-clockwise first of all on a pulley of a cranked shaft, then on a tension roller. 2. Take the steel core fixing the mechanism of a tension. 3. Establish a pulley of the fan of a radiator and fix its bolt, having tightened its moment of 40 Nanometers. The prevention The bolt of fastening of a pulley of the fan of a radiator has the left carving, therefore a bolt tightening it is necessary to make its turn counter-clockwise.

КЛИНОВЫЙ THE BELT ON FOUR-CYLINDER PETROL ENGINES, EXCEPT ENGINES AHL 1,6-I

The klinovoj belt is used for a drive of the water pump. On engines 1,6-I AHL the water pump is put in action by a gear belt.

Removal

PERFORMANCE ORDER

1. If the belt is repeatedly established, using a marker or a paint, an arrow note a direction of rotation of a belt. 2. Move forward a belt casing. 3. Reduce a tension of a belt of a drive of the pump of the amplifier of a steering, the generator and the radiator fan. Using a steel core, fix in the taken away position a tension roller of a belt. 4. Using a steel core (1) diameter of 5 mm, fix a pulley of the fan of a radiator from проворачивания, from a pulley underside unscrew a key (2) and remove the radiator fan. 5. Unscrew a pulley клинового a belt of the water pump. That the pulley was not turned, at unscrewing of bolts by a steel core or a screw-driver fix a pulley of the pump of the amplifier of a steering. 6. Remove клиновой a belt.

Installation

PERFORMANCE ORDER

1. Establish клиновой a belt. 2. Gradually and in regular intervals screw a pulley клинового a belt on the water pump. 3. Turn a pulley of the water pump for correct installation клинового a belt in pulley flutes. 4. Tighten bolts of fastening of a pulley of the water pump the moment of 25 Nanometers. to make tension adjustment клинового a belt it is not required. 5. Establish the fan of a radiator and dress клиновой a belt on a pulley of the fan of a radiator. 6. Screw the fan of a radiator a bolt, having tightened its moment of 45 Nanometers. 7. Establish a belt and adjust its tension.
