Removal and installation of a gear belt of engines VZ, B5, B6 (SOHC), BP (SOHC)
 | Removing the toothed belt of the diesel engine, see chap. Diesel engine. |
Withdrawal | - Disconnect earth cable from the battery.
| This data is erased from the memory of malfunctions of the engine or a protective code of a radio receiver. Before disconnecting the battery should read instructions in Section Removal and installation of the battery. |
- To lift the car and remove the right front wheel.
- Remove the bottom cover of the engine on the right wheel niche.
- If there is, remove the V-belt servo pump and air conditioning compressor. See section Removing and installing / belt tension.
- Loosen the bolts of the water pump pulley.
- Remove the V-belt of the generator. See Section Removal and installation / belt tension.
- Unscrew the bolts of the water pump pulley and remove the pulley.
|
|
Before 2/91, the no. | - Lock the crankshaft, and to unscrew bolts of the crankshaft pulley.
- To lock the crankshaft include 5th transfer and ask the assistant to press the brake pedal.
- Remove the washer, the crankshaft pulley, the outer and inner guide toothed belt drives.
|
|
Since 3/91 MY. | - Unscrew the bolts of the crankshaft pulley. Hold the neck of the pulley special tool MAZDA NTA 490,011,102.
- Unscrew the upper and lower casings of a gear belt.
 | - Disconnect the spark and remove the spark plug, see. Chapter Introduction.
|
- To establish the piston of 1st cylinder in the ignition position. To do this, rotate the crankshaft to coincide labels on a belt pulley of a cam with labels on timing cover and cylinder head. Simultaneously must match marks on the cylinder block and the crankshaft gear.
- For cranking include 5th transfer and to move the vehicle on a level surface. Another possibility Crank: Raise the front wheel, turn 5th gear and turn the wheel by hand.
| After the piston of 1st cylinder will be in the ignition, set the transmission to neutral and again, check whether the marks on the belt pulley and the crankshaft timing gear cover. If the labels are the same, in any case no longer rotate the crankshaft. |
 | - If the old timing belt will be installed again, it should be marked. On the belt should be applied to the arrow indicating the direction of rotation. The crankshaft rotates in the clockwise direction.
|
 | - Loosen the bolt of a tension roller and a tension roller to press in the direction of the arrow until the timing belt is not weakened. Tighten the bolt of a tension roller.
|
- Remove the timing belt, then the situation is not changing gears.
|
|
Setting | Do not bend or twist the timing belt. Dirty, damaged or worn timing belt replaced in any case. Check the uniformity and ease of movement of the tension roller. |
| If the camshaft rotates at the removed gear belt, any piston should not be in the BMT. Otherwise, you may cause serious damage to the pistons and valves. If you want to rotate the crankshaft, previously set to be half the height of all pistons. To do this, put on top of the gear crank chalk line (condition: the crankshaft is in the BMT piston of 1st cylinder), then turn the wheel of the crankshaft 1/2 turn left or right. Marking chalk is in the horizontal position. |
Before 2/91, the no. | - Install the crankshaft pulley and washer -5- and tighten the bolts to the torque of 15 Nm.
|
|
Since 3/91 MY. | - Set bolt crankshaft pulley. Hold the neck of the pulley special tool MAZDA SST D 49 011 102 and tighten the bolts to 165 Nm.
- Install the water pump pulley and tighten bolts with effort of a hand.
- Install the V-belt, see. Section Removal and installation / belt tension.
- Tighten the water pump pulley with a force of 10 Nm.
- Set candles and connect the cables, see. Chapter Introduction.
- Screw the panel on the right wheel niche.
- Install the front wheel and lower the car.
- Connect the earth cable to the battery.
- If available, set the clock and set the security code radio.
- Check ignition timing and adjust if necessary, see. Chapter Ignition system, Section Checking / adjusting the moment of ignition.
