Removal of a gear belt of the diesel engine see in the Head the Diesel engine.

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.
  2. To remove the lower guard of the engine in the right niche of a wheel.
  3. If is available, to take off maple a belt of the pump of a servoupravleniye and the compressor of the conditioner, see 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 maple a generator belt, see the Section Removal and an installation/tension of a maple belt.
  6. To turn out bolts of fastening of a belt pulley of the water pump and to remove a pulley.

To 2/91 g of the issue.

 PERFORMANCE ORDER

  1. To block the crankshaft 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, 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 neck of a belt pulley special MAZDA ZZT 490011102 adaptation.
  2. To unscrew the top and lower casings of a gear belt.
  1. To disconnect tips of candles and to remove spark plugs, see the Head Vvedeniye.
  1. To install the piston of the 1st cylinder in the provision of ignition. For this purpose to turn the crankshaft that tags on a belt pulley of a cam-shaft coincided with tags on a cover of the distributive mechanism and a head of cylinders. At the same time tags on the block of cylinders and on a crankshaft cogwheel have to coincide.
  2. For a provorachivaniye of the crankshaft to include the 5th transfer and to shift the car on a plain surface. Other opportunity to turn the crankshaft: To raise a forward wheel, to include the 5th transfer and to turn a wheel a hand.

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 the crankshaft and a cover of the drive of the distributive mechanism coincide. If tags coincide, not to turn more crankshaft at all.


  1. If the old gear belt is established again, it should be marked. On a belt it is necessary to put to the shooter, specifying the direction of rotation. The crankshaft rotates in the direction clockwise.
  1. To weaken a bolt of a tension roller and to wring out a tension roller in the direction of an arrow until the gear belt is weakened. Again to tighten a bolt of a tension roller.
  1. To take off a gear belt, after that not to change the provision of cogwheels.

Installation

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

If the cam-shaft turns at the taken-off gear belt, any piston should not be in position of BMT. Otherwise there can be serious damages of pistons and valves. If it is required to turn the crankshaft, previously it is necessary to install all pistons half height. For this purpose to put from above on a crankshaft cogwheel the line with chalk (a condition: the crankshaft is in position of the BMT piston of the 1st cylinder), then to turn a crankshaft wheel on 1/2 turns to the left or to the right. The mark chalk is in horizontal position.


 PERFORMANCE ORDER

  1. To be convinced that the cam-shaft is in the situation corresponding to VMT of the 1st cylinder. At the same time tags on a wheel of a cam-shaft and on a cover of the drive of the distributive mechanism and a head of cylinders have to coincide.
  1. At the same time the mark in a cogwheel of the crankshaft has to coincide with a mark in the block of cylinders. Then the piston of the 1st cylinder is in the provision of VMT.
  1. To impose a gear belt so that the pulling party was tense. If the old belt is established, to pay attention to the direction of its rotation.

At installation of a gear belt the provision of distributive and cranked shaft should not change. Otherwise in the engine there can be serious malfunctions, or the engine will not develop the maximum power.

  1. To weaken a bolt of a tension roller that the roller adjoined to a belt.
  2. To turn the crankshaft two times in the direction of rotation and to double-check coincidence of tags, if necessary to repeat adjustment.
  3. To tighten a bolt of fastening of a tension roller with effort of 20 Nanometers.
  4. Two times to turn the crankshaft in the direction of rotation and to double-check adjustment.
  1. To check a tension of a gear belt. The gear belt on the longest site at influence with a force of 10 kg that corresponds to pressing by a thumb, has to cave in on 11-13 mm. If value does not correspond to demanded, it is necessary to weaken a tension roller and to tighten it again.
  1. To screw the top and lower casings of a gear belt with effort of 10 Nanometers.
  2. To establish the external and internal directing disks of a gear belt according to dredging on a crankshaft wheel. To consider adjusting situation.

To 2/91 g of the issue.

 PERFORMANCE ORDER

  1. To establish a belt pulley of the crankshaft and a washer-5-and to tighten fastening bolts with effort of 15 Nanometers.

With 3/91 g of the issue.

 PERFORMANCE ORDER

  1. To establish a bolt of fastening of a belt pulley of the crankshaft. Holding a pulley neck special MAZDA SST adaptation 49 D 011102 and to tighten a bolt with effort of 165 Nanometers.
  2. To establish a belt pulley of the water pump and to tighten fastening bolts with effort of a hand.
  3. To establish a maple belt, see the Section Removal and an installation/tension of a maple belt.
  4. To tighten a belt pulley of the water pump with effort of 10 Nanometers.
  5. To establish candles and to connect cables, see the Head Vvedeniye.
  6. To screw a guard in the right niche of a wheel.
  7. To establish a forward wheel and to lower the car.
  8. To connect a weight cable to the battery.
  9. If are available, to determine time on hours and to set a protective code of the radio receiver.
  10. To check the ignition moment, if necessary to adjust, see the Head Sistem of ignition, the Section Check/adjustment of the Moment of Ignition.
