## Generator Replacement LG5

### Removal Procedure

The removal and installation instructions serve only as a guide. Additional operations may be required on some vehicles in order to remove other equipment in order to gain access to the following components:

• | The generator

• | The drive belts

• | The brackets

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 negative battery cable.
2. Disconnect the wiring connectors from the back of the generator.
3. Remove the ground strap.
4. Remove the drive belt.
5. Remove the following components from the generator:

• | The mounting bolts (4)

• | The washers and nuts (2) and (3)

6. Remove the generator (1).
7. Remove the generator pulley.

### Installation Procedure

Important: Change the pulley of the new generator if the pulley diameter is not exactly the same as the one being removed from the vehicle.

1. Install the generator pulley.

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 generator shaft nut.

Tighten
Tighten the generator shaft nut to 100 N·m (75 lb ft).

3. Install the generator to the mounting bracket using the following components:

• | The bolts (4) and (7)

• | The washers and nuts (2) and (3)

4. Finger tighten the bolts.
5. Install the ground strap.
6. Install the drive belt.
7. Install the generator mounting bolts.

Tighten

• | Tighten the top mounting bolt to 88 N·m (65 lb ft).

• | Tighten the bottom mounting bolt to 71 N·m (52 lb ft).

8. Connect the wiring connectors to the back of the generator.

Hold the hex-shaped base on the output terminal while tightening the nuts.

Tighten
Tighten the generator output terminal nut on the CS-130 and the CS-144 to 8 N·m (71 lb in).

9. Connect the negative battery cable.

Tighten

• | Tighten the side post terminal bolt to 15 N·m (11 lb ft).

• | Tighten the top post terminal nut to 12 N·m (9 lb ft).
