Signs of Wear & Troubleshooting

• Signs of wear for engine harmonic balancers include but are not limited to:
• Engine vibration
• Excessive drive belt noise
• Balancer wobble
• Abnormal sounds

• Unusual odors while the engine is operating

Good Maintenance Practices

• Before purchasing and installing an engine harmonic balancer, make sure it is the correct size and fit for your vehicle.
• Check the harmonic balancer for excessive movement or wobble.
• Check for uneven wear on the drive belt, which can indicate that the balancer pulley is out of alignment.
• Have your vehicle inspected as soon as possible if the ‘Service Engine Soon' light illuminates.
• Have your vehicle inspected immediately if the ‘Service Engine Soon' light flashes rapidly, as this could indicate an engine misfire condition which may damage your engine and/or engine emission components.
• Regularly inspect engine harmonic balancers for signs of damage or wear, and replace them if signs of damage are found.
