Removal and installation of a gear belt / adjustment of the drive of the distributive mechanism

1 — maple a belt, сервонасос
2 — maple a belt, the generator
3 — a belt pulley of the water pump
4 — a belt pulley of the crankshaft

5 — the top casing of a gear belt
6 — the lower casing of a gear belt
7 — a gear belt
8 — a tension roller and a spring

Usually the drive of the distributive mechanism is adjusted only in case of repair at which the gear belt is removed or the engine understands. If the drive of the distributive mechanism needs to be checked only, it is necessary to execute all working stages except replacement of a gear belt.

Removal

 PERFORMANCE ORDER

  1. To disconnect a weight cable from the battery.

At the same time data from memory of malfunctions of the engine or a protective code of the radio receiver are erased. Before shutdown of the battery it is necessary to read instructions in the Section Removal also installation of the battery.

  1. To lift the car and to remove the right forward wheel, see the Head Vvedeniye.
  2. To remove the lower guard of the engine in the right wheel arch.
  3. If is available, to take off maple a belt of a servonasos, see the Head Petrol engines, the Section Removal and an installation/tension of a maple belt.
  4. To weaken bolts of fastening of a belt pulley of the water pump.
  5. To take off a maple belt of the generator, see the Head Petrol engines, the Section Removal and an installation/tension of a maple belt.
  6. To turn out bolts of fastening of a belt pulley of the crankshaft and to remove a pulley.

To 2/91 g of the issue.

 PERFORMANCE ORDER

  1. To block the engine and to unscrew bolts of fastening of a belt pulley of the crankshaft.
  2. For blocking of the crankshaft to include the 5th transfer and to ask the assistant to squeeze out a brake pedal.
  3. To remove a washer, a belt pulley of the crankshaft, and also the external and internal directing disks of a gear belt.

With 3/91 g of the issue.

 PERFORMANCE ORDER

  1. To unscrew bolts of fastening of a belt pulley of the crankshaft. To hold a pin of a belt pulley special MAZDA SST adaptation 49D011102.
  2. To take out the masloizmeritelny probe.
  1. To unscrew the lower and top casings of a gear belt.
  1. To remove glow plugs, see the Section Check of System of Preheat.
  1. To install the piston of the 1st cylinder in the provision of ignition. For this purpose to turn the crankshaft so that tags on a belt pulley of the crankshaft coincided with tags on a cover of a head of cylinders.
  1. For a provorachivaniye of the crankshaft to remove a forward wheel, to include the 5th transfer and to turn a wheel hands. Other opportunity to turn the crankshaft: To tighten the emergency brake and to install the transmission in neutral situation. To turn a crankshaft wheel through the right wheel arch by means of a face head.

Not to turn the crankshaft a gear belt at all on a cogwheel of a cam-shaft or TNVD as the gear belt will be overloaded.

After the piston of the 1st cylinder is in the provision of ignition, to install the transmission in neutral situation and to double-check whether tags on a belt pulley of a cam-shaft and a cover of valves coincide, if necessary to adjust.

  1. If the old gear belt is established, it should be marked. On a belt it is necessary to put to the shooter, specifying the direction of rotation. The engine rotates clockwise.
  1. To weaken a bolt of a tension roller and to wring out a roller a key with an internal hexagon from a gear belt until the belt unloads. To tighten a bolt of a tension roller again.
  1. To take off a gear belt, after that not to change the provision of cogwheels.

Before removal to install the transmission in neutral situation and to double-check whether the tag on a cam-shaft wheel coincides with edge of a head of cylinders, if necessary to correct.

If the cam-shaft is turned at the taken-off gear belt, any piston should not be in VMT. Otherwise there can be serious damages of pistons or valves. If it is necessary to turn a cam-shaft, to install all pistons on half level. For this purpose to apply with chalk the line from above on a belt pulley of the crankshaft (provided that the crankshaft is in the provision of VMT of the 1st cylinder), then to turn a belt pulley of the crankshaft on 1/4 turns (90 °) to the right or to the left. The mark will be turned now to the right or to the left.

Installation

Not to bend and not to overwind a gear belt. Anyway to replace the polluted, damaged or worn-out belts. To check uniformity and ease of the course of a tension roller.


 PERFORMANCE ORDER

  1. To check that all cogwheels were in the necessary situation, if necessary to establish. To observe instructions in the paragraph Removal for a provorachivaniye of shaft.
  1. To fix a belt pulley of TNVD by two bolts 35 mm long.
  1. To impose a gear belt. If the former belt is established, to impose it according to the put mark.
  2. To impose a gear belt.

To be convinced that the belt faultlessly entered cogwheels.

  1. To unscrew the fixing bolts from TNVD.

Tension

 PERFORMANCE ORDER

  1. To weaken a bolt of a tension roller until it begins to press on a belt at the expense of spring force.
  2. To turn the crankshaft on two turns clockwise, so far lines of a cogwheel of a cam-shaft and a cover of a head of cylinders will coincide again. To check coincidence of all tags.
  3. To tighten a bolt of a tension roller with effort of 25 Nanometers.

At the same time not to move fastening of a roller.

  1. To turn the crankshaft on two turns in the direction of rotation and to double-check adjustment.
  2. To check a tension of a gear belt. At influence with a force of 10 kg between a belt pulley of a cam-shaft and a pulley of TNVD the belt has to be pressed through on 9,5 - 11,5 mm. Otherwise it is necessary to weaken once again a bolt of fastening of a tension roller and to tighten again.
  3. To screw the lower and top casings of a gear belt with effort of 10 Nanometers.
  4. To 2/91 g of the issue: To establish a belt pulley of the crankshaft and a washer and to tighten fastening bolts with effort of 15 Nanometers.
  5. With 3/91 g of the issue: To establish bolts of fastening of a belt pulley of the crankshaft. Holding a pin of a belt pulley special MAZDA SST adaptation 49D011102, to tighten a bolt with effort of 165 Nanometers.
  6. To establish a belt pulley of the water pump and to tighten fastening bolts by effort of a hand.
  7. To establish maple a belt, see the Head Petrol engines, the Section Removal and an installation/tension of a maple belt.
  8. To tighten a belt pulley of the water pump with effort of 10 Nanometers.
  9. To establish glow plugs.
  10. To establish and pull maple a belt, see the Head Petrol engines, the Section Removal and an installation/tension of a maple belt.
  11. If is available, to establish сервонасос, see the Head Podvesk and system of steering.
  12. To screw a guard in the right wheel arch.
  13. To insert the masloizmeritelny probe.
  14. It is recommended to check the beginning of giving of TNVD (it is carried out in a workshop).
  15. To connect a weight cable to the battery.
  16. If are available, to determine time on hours and to set a protective code of the radio receiver.
