How do you change a harmonic balancer in a car?
There is no specific way of changing a harmonic balancer in a car as almost every engine is different. You should research out on how to exactly replace the balancer in your particular model. First off, you will want to remove the belt from the crankshaft pulley and remove the mounting bolt off.
What causes a harmonic balancer to go bad?
As time goes by, the harmonic balancer attached to the crankshaft can go bad due to continuous contact with chemicals, from other elements and/or from old age. These are the factors that can cause the crankshaft to develop cracks and finally fail.
What is the purpose of a crankshaft harmonic balancer?
The crankshaft harmonic balancer is a device connected to the front of an engine’s crankshaft, usually built into the crankshaft pulley. Its purpose is to absorb and reduce harmonic vibrations from the engine as the crankshaft rotates, as harmonic vibrations at high engine speeds can…
How much does a harmonic balancer puller cost?
You will also have to go out and buy a harmonic balancer puller (a device used for safely removing a harmonic balancer without damaging other components in the car). They will cost you around $25 or so.
What is the harmonic balancer on a Honda engine?
The “Harmonic Balancer” keeps the engine vibrations down. This is important in keeping the motor running smooth and not tearing itself apart. You are dealing with a 19mm bolt, which is called the “Crank Bolt”. This holds the harmonic balancer to the crank shaft.
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 causes a crankshaft harmonic balancer to fail?
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
When is the best time to replace a harmonic balancer?
If a harmonic balancer is being replaced for a belt alignment problem, that may have damaged the belt. If the belt isn’t damaged but there is any other reason to replace the belt while it is off, or if it may be due for age or mileage, it is most economical to do when it is already off and no additional labor charge would be necessary.
What is the purpose of a harmonic balancer?
The purpose of a harmonic balancer is to dampen the harmonic vibrations that all engines produce. 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.
Do you need to remove serpentine belt on harmonic balancer?
The serpentine belt needs to be removed, then, the center bolt that holds the balancer in place. Some harmonic balancers can be simply removed at that point, but many are a press-fit and require a specific puller to remove.

How is a harmonic balancer connected to the crank pulley?
It is connected to the crank pulley. It is the rubber inside the pulley which is responsible for absorbing the vibrations generated by the crankshaft and keep them at a safe level. This helps the crankshaft from failing. By dampening the vibrations, it literally becomes its lifesaver!
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 happens when a harmonic balancer is broken?
The belt in the pulley might slip which will cause the vehicle to misfire or backfire. The ignition timing in the vehicle will be off. The vehicle might not start at all if the balancer is broken. As soon as you get these symptoms, you need to call a mechanic or else replace the balancer yourself.

Can a bad harmonic balancer cause an engine to shake?
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
What happens if you separate the harmonic balancer?
If the layers separate or slip, the timing marks, which are usually stamped into the front of the pulley, can shift and thus throw off the placement of the timing marks. This will make it difficult, if not impossible to properly time the engine with a timing light. 3. Separated harmonic balancer

What to do if your crankshaft harmonic balancer is bad?
Separated harmonic balancer. For this reason, if you suspect that your harmonic balancer may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic. They will be able to determine if the vehicle needs a crankshaft harmonic balancer replacement.

What are the symptoms of a bad harmonic balancer?
One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. The harmonic balancer is specifically designed to absorb harmonic engine vibrations as engine speeds rise. If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively.
How can you tell if your harmonic balancer is bad?
Signs of a Bad Crankshaft Harmonic Balancer Increased Engine Vibration. When the crankshaft balancer loses its harmonic functions, the issue it is supposed to control comes out in full force. Disrupted Timing Marks. The crankshaft harmonic balancer is usually found in the front of the crankshaft pulley and is attached to the crankshaft. Detached Harmonic Balancer. Loud Noise from the Engine Bay.
Does the harmonic balancer need replacing?
Harmonic balancers do have many names, though, such as damper, crankshaft pulley and crankshaft balancer, among others. While this part may not wear, or be known to wear, as quickly as a traditional idler pulley or belt tensioner, balancers do in fact wear and eventually must be replaced.
Do harmonic balancers go bad?
Over time, the crankshaft harmonic balancer can go bad from constant exposure to chemicals, the elements, or from old age. If this happens, the crankshaft may develop cracks and ultimately fail.
