Hyundai Elantra HD: Alternator. Repair procedures
Replacement
| 1. |
Disconnect the battery negative terminal(A) first, then the positive
terminal(A).
|
| 2. |
Deisconnect the alternator connector(A) and "B" terminal cable
from the alternator. Losen the cpip(B).
|
| 3. |
Remove the adjusting bolt(A), mounting bolt(B), the alternator
belt(C) and the alternator mounting bracket(D).
|
| 4. |
Pull out the through bolt, then remove the alternator(E).
|
| 5. |
Installation is the reverse of removal.
|
| 6. |
Adjust the alternator belt tension after installation.
|
Disassembly
| 1. |
Remove the alternator cover(A) after removing three nuts(B).
|
| 2. |
Loosen the mounting bolts(A) and disconnect the brush holder assembly(B).
|
| 3. |
Remove the slip ring guide(A).
|
| 4. |
Remvoe the nut, pully(A) and spacer.
|
| 5. |
Loosen the 4 through bolts(A).
|
| 6. |
Disconnect the rotor(A) and cover(B).
|
| 7. |
Reassembly is the reverse of disassembly.
|
Inspection
Rotor
| 1. |
Check that there is continuity between the slip rings(A).
|
| 2. |
Check that there is no continuity between the slip rings and the
rotor(B) or rotor shaft(C).
|
| 3. |
If the rotor fails either continuity check, replace the alternator.
|
Stator
| 1. |
Check that there is continuity between each pair of leads(A).
|
| 2. |
Check that there is no continuity between each lead and the coil
core.
|
| 3. |
If the coil fails either continuity check, replace the alternator.

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 ~ 0345 in)
New Belt : 5.5 ~ 8.0 mm (0.22 ~ 0361 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.
