Alternator Repair Procedures

Removal

1. 1
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
2. 2
   Remove the drive belt. (Refer to Engine Mechanical System - "Drive Belt")
3. 3
   Disconnect the alternator connector (A) and the cable (B) from the alternator "B" terminal.

   

4. 4
   Remove the through bolt and remove the alternator (A).

   

Installation

1. 1
   Install in the reverse order of removal.
2. 2
   After installation, adjust the alternator drive belt tension. (Refer to Engine Mechanical System - "Drive Belt") Alternator mounting bolt: [M10] 29.4 ~ 41 N·m [M8] 21.6 ~ 32 N·m Alternator brace mounting bolt: 21.6 ~ 32 N·m

Disassembly

1. 1
   Remove the rear cover (A) after loosening the nuts (B).

   

2. 2
   Remove the mounting bolts (A) and the regulator assembly (B).

   

3. 3
   Remove the slip ring guide (A) by pulling it.

   

4. 4
   Remove the OAD (Overrunning Alternator Decoupler) cover.

   When installing, replace with a new OAD cap.

5. 5
   Remove the OAD (Overrunning Alternator Decoupler) pulley (A) using the special service tool.

   

6. 6
   Unsolder the 3 stator wires (A).

   

7. 7
   Remove the 4 through bolts (A).

   

8. 8
   Separate the rotor (A) and housing (B).

   

Installation

1. Assemble in the reverse order of disassembly.

   When reassembling the OAD pulley, replace it with a new OAD cap.

Inspection

[Rotor]

1. 1
   Check that there is continuity between the slip rings (C).

   

2. 2
   Check that there is no continuity between the slip rings and the rotor (B) or the rotor shaft (A).
3. 3
   If the rotor fails the continuity check, replace the generator.

[Stator]

1. 1
   Check for continuity between each pair of wires (A).

   

2. 2
   Make sure there is no continuity between each terminal and the coil core.
3. 3
   If the coil fails the continuity check, replace the generator.
