Generator Replacement Gas, CS 144

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 battery negative cable. Refer to Battery Negative Cable Disconnection and Connection .
2. Disconnect the terminal plug from the back of the generator.
3. Disconnect the battery lead from the back of the generator.
4. Remove the upper fan shroud as needed. Refer to Fan Shroud Replacement in Engine Cooling.
5. Remove the drive belt. Refer to Drive Belt Replacement in Engine Mechanical (6.5L) or Drive Belt Replacement in Engine Mechanical (7.4L).



6. Remove the generator mounting bolts holding the generator to the brace and the bracket.
7. Remove the generator.

1. Install the generator.

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. Perform the following procedure in order to install the generator mounting bolts holding the generator to the bracket and the brace:

2.1.	Loosely install the generator mounting bolts holding the generator to the bracket and the brace.

2.2.	Install the brace attachment.

2.3.	Tighten the generator mounting bolts holding the generator to the bracket and the brace.
