REPLACEMENT
1. | Disconnect the battery negative terminal first, then the positive terminal.
2. | Disconnect the generator connector(A) and "B" terminal cable(B) from the generator(C).
3. | Remove the adjusting bolt(A) and mounting bolt(B), then remove the generator belt(C).
4. | Pull out the through bolt(C), then remove the generator(D).
5. | Installation is the reverse of removal.
6. | Adjust the generator belt tension after installation (See page EE-33 ).
1. | Disconnect the battery negative terminal first then the positive terminal.
2. | Loosen the drive belt tension adjusting bolt, then remove the drive belt(A).
3. | Disconnect the connector(A) and "B" terminal cable(B).
4. | Pull out the through bolts(A) and nuts(B) then remove the generator(C).
5. | Installation is reverse of removal.
• | Adjust the generator belt. (Refer to EM)
• | Place the alternator and insert a support bolt (Do not insert a nut this time).
• | After pushing the alternator forward, count that how many spacers (a spacer thickness : 0.198 mm) should be inserted between the alternator front leg and front case as shown in "A".
• | After inserting spacers, insert and tighten a nut securely.
ALTERNATOR BELT INSPECTION AND ADJUSTMENT
When using a new belt, first adjust the deflection or tension to the values for the new belt, then readjust the deflection or tension to the values for the used belt after running engine for five minutes.
Deflection method : Apply a force of 98N (10 kgf, 22 lbf), and measure the deflection between the alternator and crankshaft pulley.
Deflection Used Belt : 8.5 ~ 11.5 mm (0.33 ~ 0.345 in) New Belt : 5.5 ~ 8.0 mm (0.22 ~ 0.361 in)
If the belt is worn or damaged, replace it.
Belt tension gauge method : Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions.
Tension Used Belt : 340~490 N (35~50 kgf, 77~110 lbf) New Belt : 690~880 N (70~90 kgf, 150~200 lbf)
If the belt is worn or damaged, replace it.
If adjustment is necessary :
1. | Loosen the adjusting bolt(A) and the lock bolt(B).
2. | Move the alternator to obtain the proper belt tension, then retighten the nuts.
3. | Recheck the deflection or tension of the belt.
It is not necessary to adjust the tension of the drive belt because of the auto-tensioner.
