2. Loosen the alternator support nuts.
3. Loosen the alternator mounting bolt and remove the V-ribbed belt.
4. Turn out bolts of fastening of a pulley of the water pump.
Torque:
- hinge bolt (A) generator mounting: 20-25 Nm
- Bolt (IN) generator mounting: 15-22 Nm
- Alternator bracket bolt: 20-28 Nm
Examination
Check the following items and replace if defective.
1. Check the poly V-belt surface for damage and cracks.
2. Check the poly V-belt surface for oil and grease.
3. Check the poly V-belt surface for uneven wear.
4. Check the pulley surface for cracks or damage.
Installation
1. Install the pump pulley and secure it with bolts.
2. After installing the V-ribbed belt, adjust its tension.
Checking and adjusting the tension
1. Check the condition of the V-ribbed belt and its location on the pulleys.
Warning! Check that the ribs of the V-ribbed belt are correctly positioned in the grooves of the pulleys.
Warning! If the V-ribbed belt makes unusual noise during operation, check the belt for wear and damage, as well as the running surfaces of the pulleys.
2. Using a special device, measure the tension of the alternator drive belt. In the absence of a special device, check the belt tension by pressing on it with a force of 100 N (10 kg) at a location equidistant from the pulleys and measure the deflection of the belt.
Generator drive belt tension:
- New belt: 65-75 kg
- Used belt: 40 kg
- Check: 35-50 kg
Generator drive belt and power steering pump tension:
- New belt: 55-70 kg
- Used belt: 38-48 kg
Generator and air conditioner drive belt tension:
- New belt: 60-70 kg
- Used belt: 32-40 kg
- Check: 25-50 kg
A used belt is considered to be a belt that has worked on the engine for more than 5 minutes.
Tension measurement with a special device type A
When measuring the tension of the V-ribbed belt, the device must not touch other elements of the engine.
When measuring the tension of the V-ribbed belt, the device must not touch other elements of the engine.
1. When measuring, be sure to turn the reset button in the direction of the arrow to reset the instrument's pointer.
2. After removing the gauge from the belt, the gauge needle will still indicate belt tension.
Warning! It is not recommended to adjust the belt tension by hand, as this adjustment will not provide sufficient accuracy and the belt may slip on the pulleys. Always use a special device.
Warning! Check that the belt tension is correct.
Warning! Check belt tension after tightening pivot bolt and alternator mounting bolt.
