Installation Procedure


    Object Number: 204733  Size: SH

    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.

  1. Connect the positive cable to the starter.
  2. Tighten

        • Tighten the nut at the starter to 30 N·m (22 lb ft).
        • Tighten the nut at the generator to 23 N·m (17 lb ft).
  3. Connect the negative cable to the battery. Refer to Battery Negative Cable Disconnection and Connection .
