Tension of a maple or poliklinovy belt

Tension of a maple belt of the 4-cylinder engine

Maple generator belt

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

3–adjusting level.

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

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

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


The illustration shows the provision of installation of the compressor of the conditioner (1) of the 4-cylinder engine. 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. Maple a generator belt till September of 91 g: to weaken tightening a bolt on an adjusting level of the generator.
  2. To rotate the adjusting nut which was below with a gear wreath, the correct tension of a belt yet will not be established.
  3. To tighten tightening a bolt.
  4. If it is impossible to shift the generator, means, it is necessary to weaken its sharnirny bolt.
  5. It becomes available in front after removal of a casing of a gear belt.
  6. If the sharnirny bolt was weakened, again to tighten it it is necessary in the most last turn.
  7. Maple a generator belt after October of 91 g: to weaken tightening a bolt on a bracket of fastening of the generator.
  8. To weaken a sharnirny bolt in the lower part of the generator, to check a legkokhodnost.
  9. To tighten the moment of 6 N • m and to hold an adjusting nut with a gear wreath by means of a cap key of 22 mm with a dinamometrichesky head. So the tension of a belt will be true.
  10. To tighten a tightening bolt.
  11. In the last turn again to tighten a sharnirny bolt.
  12. Maple a belt for the water pump and the power steering pump: to remove the bottom protection of a motor compartment (head body Elements).
  13. To weaken tightening a bolt on a level of fastening of the pump of the power steering.
  14. To rotate the adjusting nut which was below with a gear wreath until the correct tension of a belt will be established.
  15. To tighten tightening a bolt.
  16. If the pump of the hydraulic booster cannot be shifted, means, it is necessary to weaken his sharnirny bolt.
  17. Maple belt of the compressor of the conditioner: adjustment of a tension of a belt occurs by a vynimaniye or addition of adjusting washers between a lobby and a back half of a pulley. The bigger quantity of adjusting washers between halves of a pulley means a smaller tension of a belt. The smaller quantity of adjusting washers between halves of a pulley leads to a bigger tension of a belt.
  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 of 25 N • m, watching thus that maple a belt did not jam between pulley halves.
  20. Two times to turn a cranked shaft.
  21. To check a belt tension in strong pressing of a thumb on an empty seat between cranked shaft and the conditioner compressor.
  22. To get the engine and let's to it work a little.
  23. Again to check a tension of a maple belt, if necessary to add or clean adjusting washers.
  24. At the correct tension of a belt to tighten bolts once again the moment of 25 N • m.

Models with 5-cylinder engines

Tension of a maple belt of the 5-cylinder engine

Maple generator belt

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

3–tightening bolt.

Maple belt of the pump of the hydraulic booster.

1–adjusting bolt;
2–fixing nut of a lath of fastening;

3–fixing nut of a rotary lath.


 PERFORMANCE ORDER

  1. Maple generator belt: to weaken tightening a bolt on a fastening lath.
  2. To turn the adjusting nut located below 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 a sharnirny bolt (the bottom fastening of the generator) at the removed bottom protection of a motor compartment.
  5. Maple belt of the pump of the power steering: to weaken fixing nuts on a lath of fastening and a rotary lath.
  6. For a tension of a belt to turn a tension bolt to the left, that is to turn out.
  7. Again to tighten nuts.
  8. Maple 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 side 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 of a poliklinovy belt at model with the 6-cylinder engine. In drawing the tension roller is fixed by means of a six-sided punch that gives the chance to turn it a cap key. In the photo the zvezdchaty bolt which for a provorachivaniye the zvezdchaty head with a suitable cap key (2) is put on is visible. Pin (1; on an illustration this role is carried out by a punch) is inserted into the opening provided for this purpose on the tension device thanks to what the tension device is fixed in this situation.

  • The tension of a poliklinovy 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.
