Generator Replacement

Removal Procedure

    Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

  1. Disconnect the battery negative cable.
  2. Remove the air cleaner assembly.
  3. Remove the drive belt.
  4. Disconnect the regulator electrical connector.

  8. Remove the generator.

Installation Procedure

    Object Number: 332407  Size: SH

  1. Position the generator on the vehicle.

    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.

  2. Loosely install the mounting bolts.
  3. Install the generator output (BAT) lead.
  4. Loosely install the generator output (BAT) nut.


    Tighten the mounting bolts to 50 N·m (37 lb ft).
    Tighten the generator output (BAT) terminal nut to 20 N·m (15 lb ft).

  5. Connect the regulator electrical connector.
  6. Install the drive belt.
  7. Install the air cleaner.
  8. Connect the battery negative cable.
