Tools Required

Important: When the brackets affecting belt alignment are installed on the engine, a very specific installation and torque sequence must be followed. Failure to follow the specific installation and torque sequence may cause improper belt position and a subsequent lack of belt retention condition.

1. Remove the cooling fan. Refer to Fan Replacement .
2. Remove the drive belt.
3. Remove the generator. Refer to Generator Replacement in Engine Electrical.
4. Remove the generator adjusting bracket from the fan drive support assembly bolts.



5. Loosen the air conditioning compressor mounting bolts, if equipped.
6. Loosen the air conditioning compressor lower mounting bracket bolts, if equipped.



7. Remove the fan drive support assembly bolts.
8. Remove the fan drive support assembly from the engine.

1. Install the fan drive support assembly to the engine.

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. Install the fan drive support assembly mounting bolts.
