2.7.5. Removal and installation of a poliklinovy belt

GENERAL INFORMATION

Arrangement of belts on four-cylinder petrol engines

1 –  belt tension device,
2 – generator,
3 – fan,
4 – water pump,
5 – pump of the amplifier of steering,
6 – belt of the water pump,
7 – belt of the amplifier of steering of the fan and generator,
8 – quencher of fluctuations,
9 – conditioner compressor belt tension mechanism,
10 – conditioner compressor belt,
11 – conditioner compressor

Poliklinova the belt is in fact, a flat belt, on the one hand which there are ribs. Poliklinova the belt carries out the drive of the generator, the pump of the amplifier of steering, вентилято ра a radiator, the compressor of the conditioner and the water pump depending on modification of the engine. On models with four-cylinder engines with the air conditioning system for the drive of the compressor of the conditioner the separate belt is used.

CONDITIONER COMPRESSOR BELT ON FOUR-CYLINDER ENGINES WITH THE AIR CONDITIONING SYSTEM

Removal

PERFORMANCE ORDER
1. Take off poliklinovy belts of the drive of the pump of the amplifier of steering, the generator and fan of a radiator.
2. If the belt is repeatedly established, using a marker or paint, an arrow note the direction of its rotation.
3. Weaken screws of fastening of the mechanism of a tension of a poliklinovy belt and after weakening of a tension of a poliklinovy belt remove it from pulleys.

Installation

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

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

Removal

PERFORMANCE ORDER
1. If the belt is repeatedly established, using a marker or paint, note the direction of rotation of a belt.
2. Move a belt casing forward.
3. For weakening of a tension of a belt, using a wrench, turn the tension mechanism clockwise and record it a steel core with a diameter of 5 mm.
4. Take off a belt from pulleys.

Installation

PERFORMANCE ORDER
1. Check 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 belt tension mechanism in the direction of an hour hand and take the steel core fixing the tension mechanism. Slowly release the belt tension mechanism, at the same time there will be an automatic tension of a belt.
4. Establish into place a belt casing.
5. Start the engine and check work of belts.

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

Operations on removal and installation of a belt are similar to operations on removal and installation of a belt for the four-cylinder petrol engine. Only the operations characteristic of diesel engines are given in this subsection.


PERFORMANCE ORDER
1. A wrench for a head of a bolt turn a tension roller counterclockwise and take off a belt. The bolt has the left carving therefore at its turn counterclockwise it will not be unscrewed.

Installation

PERFORMANCE ORDER
Wrench for a head of a bolt turn a tension roller of a belt clockwise and establish a belt on pulleys. Slowly release a tension roller, at the same time the tension of a belt will be adjusted automatically.

FIVE-CYLINDER ENGINE

Removal


PERFORMANCE ORDER
1. Unscrew four bolts fixing the fan of a radiator from a nave and remove it.
2. a 15-millimeter face wrench turn a bolt of fastening of the mechanism of a tension counterclockwise and take off a belt.

Installation

PERFORMANCE ORDER
Using a cap wrench, turn a tension roller clockwise and put on a driving belt. Slowly release a tension roller, at the same time there will be an automatic tension of a driving belt.

SIX-CYLINDER ENGINE

Arrangement of an auxiliary driving belt on the six-cylinder engine

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

Prevention

On cars without air conditioning system the auxiliary driving belt is established from a pulley 6 on a pulley 4.


Removal

PERFORMANCE ORDER
1. Holding a radiator fan pulley from a provorachivaniye, a special key of 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 needs to be rotated clockwise.
2. A wrench turn the belt tension mechanism clockwise before combination of openings. Fix the tension mechanism in this situation, having inserted a steel core with a diameter of 5 mm into an opening.

Installation

PERFORMANCE ORDER
1. Put on a driving belt in the direction counterclockwise first of all on a pulley of a bent shaft, then on a tension roller.
2. Take the steel core fixing the tension mechanism.
3. Establish a pulley of the fan of a radiator and fix it by a bolt, having tightened its moment 40 Nanometers.
Prevention

The bolt of fastening of a pulley of the fan of a radiator has the left carving therefore tightening of a bolt it is necessary to make turn it counterclockwise.



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


Maple the belt is used for the 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 paint, an arrow note the direction of rotation of a belt.
2. Move a belt casing forward.
3. Reduce a tension of a belt of the drive of the pump of the amplifier of steering, the generator and fan of a radiator. Using a steel core, record a tension roller of a belt in the taken-away situation.
4. Using a steel core (1) with a diameter of 5 mm, record a radiator fan pulley from a provorachivaniye, from a reverse side of a pulley unscrew a key (2) and remove the radiator fan.
5. Unscrew a pulley of a maple belt of the water pump. In order that the pulley was not turned, when unscrewing bolts a steel core or the screw-driver record a pulley of the pump of the amplifier of steering.
6. Take off maple a belt.

Installation

PERFORMANCE ORDER
1. Establish maple a belt.
2. Gradually and evenly screw a pulley of a maple belt on the water pump.
3. Turn a pulley of the water pump for the correct installation of a maple belt in pulley flutes.
4. Tighten bolts of fastening of a pulley of the water pump the moment of 25 Nanometers. · It is not required to make adjustment of a tension of a maple belt.
5. Install the fan of a radiator and put on maple a belt on a radiator fan pulley.
6. Screw the radiator fan a bolt, having tightened its moment 45 Nanometers.
7. Establish a belt and adjust its tension.
