Tension клинового or поликлинового a belt

Tension клинового a belt of the 4-cylinder engine

Klinovoj belt of the generator

1 – tightening a bolt;
2 – an adjusting nut with a gear wreath;

3 – an adjusting lath.

Klinovoj belt of the pump of the hydraulic booster of the steering mechanism

1 – a safety bolt;
2 – tightening a bolt;

3 – an adjusting nut with a gear wreath.

Details of a pulley of a cranked shaft at models with the 4-cylinder engine and the conditioner

1 – a pulley nave;
2 – superfluous adjusting washers;
3 – a forward half of a pulley;

4 – adjusting washers;
5 – a back half of a pulley.


The illustration shows position of installation of the compressor of the conditioner (1) 4-cylinder engines. The 4-cylinder engine has an additional pulley (2) established in front on which there is an adjustment of a tension of a belt.

Models with 4-cylinder engines

 PERFORMANCE ORDER

  1. Klinovoj belt of the generator till September of 91: to weaken tightening a bolt on an adjusting lath of the generator.
  2. To rotate an adjusting nut being more low with a gear wreath, the correct tension of a belt will not be established yet.
  3. To tighten tightening a bolt.
  4. If it is impossible to shift the generator, means, it is necessary to weaken it шарнирный a bolt.
  5. It becomes accessible in front after removal of a casing of a gear belt.
  6. If шарнирный the bolt has been weakened, again to tighten it it is necessary in the latest turn.
  7. Klinovoj belt of the generator after October of 91: to weaken tightening a bolt on скобе generator fastenings.
  8. To weaken шарнирный a bolt in the bottom part of the generator, to check up легкоходность.
  9. To tighten the moment 6 Н•м and to hold an adjusting nut with a gear wreath with the help накидного a key of 22 mm with динамометрической a head. So the belt tension will be true.
  10. To tighten a tightening bolt.
  11. In last turn again to tighten шарнирный a bolt.
  12. Klinovoj belt for the water pump and the pump of the hydraulic booster of a wheel: to remove the bottom protection of a motor compartment (the head body Elements).
  13. To weaken tightening a bolt on a lath of fastening of the pump of the hydraulic booster of a wheel.
  14. To rotate an adjusting nut being more low with a gear wreath until the correct tension of a belt will be established.
  15. To tighten tightening a bolt.
  16. If the hydraulic booster pump cannot be shifted, means, it is necessary to weaken it шарнирный a bolt.
  17. Klinovoj belt of the compressor of the conditioner: adjustment of a tension of a belt occurs by вынимания or additions of adjusting washers between a forward and back half of pulley. The bolshee quantity of adjusting washers between pulley halves means a smaller tension of a belt. The smaller quantity of adjusting washers between pulley halves leads большему to a belt tension.
  18. It is necessary to put superfluous adjusting washers between a nave and a forward half of a pulley.
  19. To tighten nuts the moment 25 Н•м, watching thus that клиновой a belt has not jammed between pulley halves.
  20. Two times to turn a cranked shaft.
  21. To check up a belt tension strong pressing of a thumb an empty seat between cranked shaft and the conditioner compressor.
  22. To get the engine and to allow to it to work a little.
  23. Again to check up a tension клинового a belt, if necessary to add or clean adjusting washers.
  24. At a correct tension of a belt to tighten bolts once again the moment 25 Н•м.

Models with 5-cylinder engines

Tension клинового a belt of the 5-cylinder engine

Klinovoj belt of the generator

1 – gear рейкой;
2 – an adjusting nut with a gear wreath;

3 – tightening a bolt.

Klinovoj belt of the pump of the hydraulic booster.

1 – an adjusting bolt;
2 – a fixing nut рейки fastenings;

3 – a fixing nut rotary рейки.


 PERFORMANCE ORDER

  1. Klinovoj belt of the generator: to weaken tightening a bolt on рейке fastenings.
  2. To turn the adjusting nut located more low with a gear wreath until the true tension of a belt will be established.
  3. To tighten tightening a bolt.
  4. If it is impossible to turn the generator, it is necessary to weaken a little шарнирный a bolt (the bottom fastening of the generator) at the removed bottom protection of a motor compartment.
  5. Klinovoj belt of the pump of the hydraulic booster of a wheel: to weaken fixing nuts on рейке fastenings and rotary рейке.
  6. For a belt tension to turn a tension bolt to the left, that is to turn out.
  7. Again to tighten nuts.
  8. Klinovoj belt of the compressor of the conditioner: to weaken tightening bolts ahead and behind on an arm of the compressor of the conditioner.
  9. Arm of the compressor of the conditioner together with the compressor to take away to the right party of the car. If necessary to use the lever from below.
  10. If a belt tension correct, again to tighten tightening bolts.

Models with 6-cylinder engines

Tension поликлинового a belt at model with the 6-cylinder engine. In drawing the tension roller is fixed with the help шестигранного a punch that gives the chance to turn it накидным a key. In a photo it is visible звездчатый a bolt which for проворачивания the head with approaching накидным a key (2) is put on звездчатая. A pin (1; on an illustration this role is carried out by a punch) is inserted into the aperture provided for this purpose on the tension device thanks to what the tension device is fixed in this position.

  • The tension поликлинового a belt is provided with the tension roller loaded with effort of a spring. Regulation is not required.
  • If the spring is broken, the belt freely sags over pulleys. In this case it is necessary to replace the tension device.
