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.
  2. To remove the bottom guard of the engine in the right niche of a wheel.
  3. If is available, to remove maple a belt of the pump of a servoupravleniye and the conditioner compressor, see. 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 maple a generator belt, see. Section Removal and 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 вып.

 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 remenny pulley of the crankshaft, 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 neck of a belt pulley the special MAZDA SST 49 adaptation D 011102.
  2. To take out a core for measurement of level of oil.
  1. To unscrew the top, average and bottom casings of a gear belt.
  1. To remove spark plugs, see. Head Introduction.
  2. To establish the piston of the 1st cylinder in the provision of ignition. For this purpose to turn the crankshaft that labels on a belt pulley of a cam-shaft coincided with labels on a cover of the distributive mechanism.
  3. For a provorachivaniye of the crankshaft to include the 5th transfer and to shift the car on an equal surface. Other possibility to turn 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 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 the crankshaft and a cover of a drive of the distributive mechanism coincide. If labels coincide, not to turn at all more crankshaft.


  1. If the old gear belt is established again, it is necessary to mark it. 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 arrow direction while the gear belt will not be weakened. Again to tighten a bolt of a tension roller.

At an otzhimaniye of a roller to enclose a rag not to damage a gear belt or a tension roller.

  1. To remove a gear belt after that the provision of cogwheels not to change.

Installation

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

If the cam-shaft turns at the removed gear belt, any piston should not be in situation VMT. Otherwise there can be serious damages of pistons and valves. If it is required to turn the crankshaft, previously it is necessary to establish all pistons on polovinny height. For this purpose to put from above on a crankshaft cogwheel the line with chalk (a condition: the crankshaft is in position VMT of the 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 situation.


 PERFORMANCE ORDER

  1. To be convinced that the cam-shaft is in the situation relevant to VMT of the 1st cylinder. Labels on a wheel of a cam-shaft and labels on a cover of a drive of the distributive mechanism thus should coincide.
  2. To check, whether labels on a cogwheel of a cam-shaft and the block of cylinders coincide.
  3. To impose a gear belt so that the branch between a wheel of a final cam-shaft and a wheel of the crankshaft was tense. If the old belt is established, to pay attention to the direction of its rotation.

At installation gear a 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 capacity.


  1. To be convinced that camshafts are in the situation relevant to VMT of the 1st cylinder. Labels on cam-shaft cogwheels thus should coincide with labels on a cover of a drive of the distributive mechanism and a head of cylinders.
  1. At the same time labels on a cogwheel of the crankshaft and the block of cylinders should coincide. Then the engine is in position VMT of the piston of the 1st cylinder.
  2. To turn the crankshaft two times in the direction of rotation and once again to check coincidence of labels, if necessary to repeat adjustment.
  1. To turn the crankshaft in the rotation direction to a label of a tension which is approximately in 60 before VMT mark.
  1. To weaken a bolt of a tension roller that the roller adjoined to a belt.
  2. To tighten a bolt of fastening of a tension roller with effort of 45 Nanometers.
  3. Two times to turn the crankshaft in the direction of rotation and once again to check adjustment.
  4. To check a tension of a gear belt. The gear belt on a site between two belt pulleys of cam-shafts at influence with force of 10 kg that corresponds to pressing a thumb, should cave in on 9-11 mm. If value does not correspond to the requirement, it is necessary to weaken a tension roller and to tighten it again.
  5. To screw the top, average and bottom casings of a gear belt with effort of 10 Nanometers.
  1. To establish external and internal directing disks of a gear belt according to dredging on a crankshaft wheel. To consider adjusting situation.

To 2/91 g вып.

 PERFORMANCE ORDER

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

With 3/91g. вып.

 PERFORMANCE ORDER

  1. To establish a bolt of fastening of a belt pulley of the crankshaft. Holding a pulley neck the special adaptation
  2. MAZDA SST 49D011102 and to tighten a bolt with effort of 165 Nanometers.
  3. To establish a remenny pulley of the water pump and to tighten fastening bolts with effort of a hand.
  4. To establish maple a belt, see. Section Removal and installation/tension of a maple belt.
  5. To tighten a remenny pulley of the water pump with effort of 10 Nanometers.
  6. To establish spark plugs and to connect tips, see. Head Introduction.
  7. To screw a guard in the right niche of a wheel.
  8. To insert masloizmeritelny щуп.
  9. To establish a forward wheel and to lower the car.
  10. To connect a weight cable to the battery.
  11. If are available, to establish time on hours and to set a protective code of a radio receiver.
  12. To check the ignition moment, if necessary to adjust, see. Head ignition System, Section Check/adjustment of the moment of ignition.
