Generator Replacement 3.4L

The generator does not require periodic lubrication. The rotor shaft is mounted on bearings. Each bearing contains a permanent grease supply. Periodically check the mounting bolts for tightness, and the drive belt tension. The drive belt is self-adjusting, within the operating limits of the tensioner. Refer to Drive Belt Tensioner Diagnosis for tensioner information.

Removal Procedure

    Important: Service the CS-130D generator as a complete unit.

  1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
  2. Remove the drive belt. Refer to Drive Belt Replacement in Engine Mechanical - 3.4L.

Installation Procedure


    Object Number: 191535  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. Install the generator (2).
  2. Tighten

        • Tighten the bolts to 50 N·m (37 lb ft).
