Removal Procedure

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  1. Disconnect the negative battery cable.
  2. Remove the air cleaner hose.
  3. Disconnect the generator electrical connector.
  4. Remove the rubber protector, the nut and the electrical connector from the generator B+ terminal.

  5. Object Number: 711382  Size: SH
  6. Remove the adjusting bolt (1) and pivot bolt (2) and move the generator (3) aside.
  7. Remove the bolts and the upper generator bracket.
  8. Remove the generator from the vehicle.

Installation Procedure

  1. Install the generator to the vehicle.
  2. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  3. Install the generator upper bracket to the vehicle. Secure the generator bracket with the bolts.
  4. Tighten
    Tighten the generator upper bracket bolts to 45 N·m (32 lb ft).

    Important: Do not torque the bolts until the drive belt tension is correct.

  5. Install the adjusting bolt (1) and pivot bolt (2) to the generator.
  6. Install the drive belt to the pulleys.
  7. Remove slack from the belt by pulling on the generator in order to obtain 9-11 mm (0.35- 0.43 in) of belt deflection under 10 kg (22 lbs) of force.
  8. Secure the generator with the adjusting bolt and pivot bolt.
  9. Tighten
    Tighten the generator bolts to 23 N·m (17 lb ft).

  10. Connect the electrical connector to the generator B+ terminal. Secure the connector with one nut and the rubber protector.
  11. Tighten
    Tighten the electrical connector nut to 8 N·m (71 lb in).

  12. Connect the generator electrical connector.
  13. Install the air cleaner hose.
  14. Connect the negative battery cable.
  15. Tighten
    Tighten the negative battery cable-to-negative battery terminal retainer to 8 N·m (71 lb in).
