Alternator drive belt
Withdrawal Removal in the following order: - Disconnect "minus" wire from the battery terminals;
A WARNING The information in the electronic memory storage device will then be lost. |
| Fig. 15.6. Location adjusting nut and bolt mechanism alternator belt tension: 1 - a bolt; 2 - an adjusting nut
|
- Loosen the bolt of the generator to the bracket and adjust the belt tension bolt (Fig. 15.6), and then turn the generator to the engine; - On vehicles equipped with air conditioning and power steering, first of all remove their belts; - Remove the drive belt from pulleys.
Installation and tension adjustment Install the new drive belt on pulleys, with belt should be centered on pulleys. Belt tension can be done in two ways.
| Fig. 15.7. Designated check belt tension (arrow): 1 - the alternator drive pulley; 2 - belt; 3 - the water pump pulley; 4 - the crankshaft pulley
|
| Fig. 15.8. Designated check belt tension with the steering amplifier (indicated by arrows): 1 - the alternator drive pulley; 2 - alternator drive belt; 3 - the water pump pulley; 4 - drive belt power steering pump; 5 - a pulley of power steering pump; 6 - the crankshaft pulley
|
| Fig. 15.9. Designated check belt tension with air conditioning (arrows): 1 - the alternator drive pulley; 2 - alternator drive belt; 3 - a pulley of the air conditioning compressor; 4 - C compressor drive belt; 5 - the water pump pulley; 6 - the crankshaft pulley
|
| Fig. 15.10. Designated check belt tension with power steering and air conditioning (arrows): 1 - the alternator drive pulley; 2 - alternator drive belt; 3 - a pulley of the air conditioning compressor; 4 - C compressor drive belt; 5 - the water pump pulley, 6 - Belt drive power steering pump; 7 - a pulley of power steering pump; 8 - the crankshaft pulley

In the first case loosen the screw and rotate the adjusting nut tightening mechanism so that the generator is moved from the engine while the deflection of the drive belt in the middle of the long branch of the belt will not be 2.0 mm when pressed with the thumb - of the new belt, and 5.0 mm - Belt Used (Fig. 15.7, 15.8, 15.9, 15.10, 15.11). Lock nut tightening mechanism in this position and tighten the adjusting screw (Fig. 15.12). If belt tension the second method requires a torque wrench. Make sure the alternator mounting bolts to the bracket has been weakened, and the oscillator moves freely. Tighten the tensioner to 8 N ?� m for the new belt (or 4 Nm for the belt used), then mark the position of the generator to an adjusting lath. Tighten the bolt of the generator to an arm, and check the nut tightening mechanism has remained in the same position. If necessary, readjust. Tighten the adjusting bolt.
