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

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

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

Usually the drive of the distributive mechanism is regulated only in case of repair at which the gear belt acts in film or the engine understands. If the drive of the distributive mechanism is necessary for checking only, it is necessary to execute everything working stages except replacement of a gear belt.

Removal

 PERFORMANCE ORDER

  1. To disconnect a weight cable from the battery.

Data from memory of malfunctions of the engine or protective code of a radio receiver are thus erased. Before shutdown of the battery it is necessary to read instructions in the Section Removal and battery installation.

  1. To lift the car and to remove the right forward wheel, see. Head Introduction.
  2. To remove the bottom guard of the engine in the right wheel arch.
  3. If is available, to remove maple a belt сервонасоса, see. Head Petrol engines, Section Removal and installation/tension of a maple belt.
  4. To weaken bolts of fastening of a belt pulley of the water pump.
  5. To remove a maple belt of the generator, see. Head Petrol engines, Section Removal and 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 вып.

 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 remenny pulley of the crankshaft, and also external and internal directing disks of a gear belt.

With 3/91 g вып.

 PERFORMANCE ORDER

  1. To unscrew bolts of fastening of a belt pulley of the crankshaft. To hold a pin of a belt pulley the special MAZDA SST 49D011102 adaptation.
  2. To take out masloizmeritelny щуп.
  1. To unscrew the bottom and top casings of a gear belt.
  1. To remove glow plugs, see. Section Check of system of preheat.
  1. To establish the piston of the 1st cylinder in the provision of ignition. For this purpose to turn the crankshaft so that labels on a belt pulley of the crankshaft coincided with labels 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 possibility to turn crankshaft: To tighten the hand brake and to establish a transmission in neutral situation. To turn a crankshaft wheel through the right wheel arch by means of a face head.

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

After the piston of the 1st cylinder will be in the provision of ignition, to establish a transmission in neutral situation and once again to check, whether labels 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 is necessary to mark it. 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 natural an internal shestigrannik from a gear belt while the belt will not unload. To tighten a bolt of a tension roller again.
  1. To remove a gear belt after that the provision of cogwheels not to change.

Before removal to establish a transmission in neutral situation and once again to check, whether the label 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 removed 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 establish all pistons on polovinny level. For this purpose to put with chalk the line from above on a remenny pulley of the crankshaft (provided that the crankshaft is in position VMT of the 1st cylinder), then to turn a remenny 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

Gear belt not to bend and not to overwind. The polluted, damaged or worn-out belts in any case to replace. To check uniformity and ease of a 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 remenny pulley of TNVD two bolts the in length of 35 mm.
  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 into cogwheels.

  1. To unscrew fixing bolts from TNVD.

Tension

 PERFORMANCE ORDER

  1. To weaken a bolt of a tension roller while it will not start to press on a belt at the expense of force of a spring.
  2. To turn the crankshaft on two turns clockwise while lines of a cogwheel of a cam-shaft and a cover of a head of cylinders again will coincide. To check coincidence of all labels.
  3. To tighten a bolt of a tension roller with effort of 25 Nanometers.

Roller fastening thus not to move.

  1. To turn the crankshaft on two turns in the direction of rotation and once again to check adjustment.
  2. To check a tension of a gear belt. At influence with force of 10 kg between a belt pulley of a cam-shaft and TNVD pulley the belt should 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 bottom and top casings of a gear belt with effort of 10 Nanometers.
  4. To 2/91 g вып.: To establish a remenny pulley of the crankshaft and a washer and to tighten fastening bolts with effort of 15 Nanometers.
  5. With 3/91 g вып.: To establish bolts of fastening of a belt pulley of the crankshaft. Holding a pin of a belt pulley the special MAZDA SST 49D011102 adaptation, to tighten a bolt with effort of 165 Nanometers.
  6. To establish a remenny pulley of the water pump and to tighten bolts of fastening by effort of a hand.
  7. To establish maple a belt, see. Head Petrol engines, Section Removal and installation/tension of a maple belt.
  8. To tighten a remenny pulley of the water pump with effort of 10 Nanometers.
  9. To establish glow plugs.
  10. To establish and pull maple a belt, see. Head Petrol engines, Section Removal and installation/tension of a maple belt.
  11. If is available, to establish сервонасос, see. Head Suspension bracket and steering system.
  12. To screw a guard in the right wheel arch.
  13. To insert masloizmeritelny щуп.
  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 establish time on hours and to set a protective code of a radio receiver.
