Removal
1. Loosen the water pump pulley mounting bolts.
2. Loosen the generator support nuts.
3. Loosen the generator mounting bolt and remove the poly V-belt.
4. Remove the water pump pulley mounting bolts.
Tightening torque:
- Generator mounting pivot bolt (A): 20–25 N·m
- Generator mounting bolt (B): 15–22 N·m
- Generator bracket mounting bolt: 20–28 N·m
Examination
Check the following items and replace them if any are defective.
1. Check the surface of the poly V-belt for damage and cracks.
2. Check the surface of the poly V-belt for oil and grease.
3. Check the surface of the poly V-belt for uneven wear.
4. Check the pulley surface for cracks or damage.
Installation
1. Install the pump pulley and secure it with bolts.
2. Install the pump pulley and secure it with bolts.
Checking and adjusting tension
1. Check the condition of the poly V-belt and its position on the pulleys.
Warning! Check that the ribs of the poly V-belt are correctly positioned in the grooves of the pulleys.
Warning! If the poly V-belt makes any extraneous noise during operation, check the belt for wear and damage, as well as the working surfaces of the pulleys.
2. Use a special device to measure the tension of the alternator drive belt. If you do not have a special device, check the belt tension by pressing it with a force of 100 N (10 kg) in a place located at the same distance from the pulleys and measure the belt deflection.
Generator drive belt deflection when checking tension:
- New belt: 7.5-9.0 mm/ /64-73 kg
- Used belt: 9.0-10.4 mm/ /39 kg
- Test: 5.0-6.0 mm/ 34-49 kg
Generator and power steering pump drive belt deflection when checking tension:
- New belt: 8mm
- Used Belt: 6.0-7.0mm
Generator and air conditioner drive belt deflection when checking tension:
- New belt: 6.0-9.0 mm
- Used Belt: 9.0-10.0mm
Warning! A used belt is one that has been in operation on the engine for more than 5 minutes.
Measuring tension with a special device
1. When measuring the tension of the poly V-belt, the device must not touch other engine elements.
2. Adjust the power steering pump belt deflection or tension.
3. Tighten the adjusting bolt.
4. Turn the engine crankshaft a few revolutions.
5. Check the belt tension and readjust if necessary.
