What causes a crankshaft harmonic balancer to fail?
Separated harmonic balancer. If the rubber layer in the harmonic balancer dries or wears out, it can cause the entire harmonic balancer to completely fail by separating. If the harmonic balancer separates, the engine belts will usually come off and the vehicle will be left without engine accessories.
What are the symptoms of a bad harmonic balancer?
They are usually made of rubber and metal, which easily absorbs any harmonic vibrations that could harm the engine otherwise. Usually a problem with the harmonic balancer will produce a few symptoms that can alert the driver of a potential problem that should be serviced.
What causes ignition timing to go off without a harmonic balancer?
Without a functioning harmonic balancer your vehicle’s ignition timing will be thrown off. According to the automotive diagnostic website AA1 Car, bad ignition timing is due to an erratic signal from the camshaft sensor caused by harmonic balancer’s inability to stabilize the component.
What does the harmonic balancer do in a car?
The harmonic balancer is the unsung hero of your vehicle’s engine. This component works with the camshaft sensor to keep engine components operating smoothly and belts running without slipping.

What happens if a harmonic balancer is loose?
A loose harmonic balancer can wobble and mess up the crankshaft. For peace of mind let another mechanic torque it again. One type of damage that can happen if the harmonic balancer bolt is loose is that the HB hub wears and the key and keyways in the HB hub and crankshaft nose wallow out.

On many engines, the harmonic balancer is integrated into the crank pulley. They do not fail often, but excess engine vibrations and misaligned timing marks are among the symptoms of a bad or failing crankshaft harmonic balancer
How do you remove a harmonic balancer unit?
Step 3: Remove the harmonic balancer bolt. Remove the harmonic balancer bolt by using the strap wrench to hold the balancer still. Hold it still while loosening the bolt with a socket and ratchet handle or breaker bar. It will be very tight, so pull hard. Step 4: Remove the harmonic balancer unit.
Where is the harmonic balancer on a car?
Step 1: Prepare the vehicle. Jack the vehicle up high enough to obtain access to the harmonic balancer, located on the front of the motor and attached to the crankshaft. Step 2: Remove the accessory drive belts. On many modern vehicles, there is an automatic, spring-loaded belt tensioner that can be rotated to loosen the belt.

How do you change the tension on a serpentine belt?
For serpentine belts this is done by compressing the spring loaded tensioner. Some tensioners can be compressed with simple hand tools such as a wrench, and others may require a special tool. V-belts can be removed by adjusting the position of one of their pulleys to release tension.
What is the purpose of a harmonic pulley?
The purpose of the harmonic balancer is to reduce engine vibration and in many cases, serve as a pulley for drive belts. Harmonic balancer’s do have many names, though, such as damper, crankshaft pulley and crankshaft balancer, among others.
What’s the best way to replace a harmonic balancer?
Note: Use your cell phone to take a picture of the belt routing for future reference. Step 3: Remove the harmonic balancer bolt. Remove the harmonic balancer bolt by using the strap wrench to hold the balancer still. Hold it still while loosening the bolt with a socket and ratchet handle or breaker bar. It will be very tight, so pull hard.
What does a crankshaft pulley do for a car?
Crankshafts are responsible for driving the car wheels. Crankshaft pulleys transmit mechanical power and torque, or the force of motion, through the pulley system to additional car elements, such as the power steering pump and alternator. All rights reserved.
