Is replacing a harmonic balancer hard?
Replacing a harmonic balancer is a three-step process. In many cases, the hardest part is removing the center crankshaft bolt. For that you’ll need the proper ½-in. drive size socket and an air, electric or battery power impact wrench.
What happens if your harmonic balancer goes bad?
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.
How do I know if my harmonic balancer needs replacing?
The most common symptoms of a bad harmonic balancer include:
- Engine Vibrations. The harmonic balancer’s job is to dampen vibrations applied to the crankshaft.
- Noticeable Harmonic Balancer Wobble.
- Unusual Noises.
- Illuminated Check Engine Light.
- Visible Wear or Damage.
Can you change a harmonic balancer?
Remove the belt from the crankshaft pulley. In most cases the crankshaft pulley is part of the harmonic balancer. Using a suitable socket and ratchet, remove the harmonic balancer mounting bolt. Match the replacement part to the old harmonic balancer before installation.
How much should it cost to replace a harmonic balancer?
The cost to replace the harmonic balancer could be around $100 to $500 depending on your vehicle type.
Does harmonic balancer affect timing?
Another symptom of a potential problem with the harmonic balancer is, misaligned timing marks. If the layers separate or slip, the timing marks can shift. This will make it, difficult if not impossible; to properly time the engine with a timing light.
Is crankshaft pulley same as harmonic balancer?
Is a crankshaft pulley and harmonic balancer the same thing? – Quora. No! They are two different things. The harmonic balancer slides onto the front of the crankshaft which has a keyway on it to keep it from slipping and a bolt and wide washer holds it in place.
How do you test a harmonic balancer?
Start your engine and check the harmonic balancer to see if it wobbles while the engine is running. Take a flashlight and shine it directly onto the balancer to see if it goes in and out while rotating. If it wobbles, the harmonic balancer is bad.
Can a harmonic balancer leak oil?
A crankshaft oil leak is much more common at the front of your motor because the harmonic balancer doesn ‘t shield the oil seal as well as the larger flywheel and the front of the motor is usually subject to all sorts of road debris, salt, and grit that can deteriorate the seal over time.
What is the rubber for in a harmonic balancer?
The harmonic balancer (also known as the crankshaft damper) is a round disc made of rubber and metal that absorbs vibrations caused by the engine cylinders’ firing. It protects the crankshaft.
How long does harmonic balancer last?
On certain engines, sometimes these last forever, last the life of the engine. And certain engines they might only last 50,000 miles or less than 10 years.
How do I know if my harmonic balancer has slipped?
There is a scribe mark on the face of the balancer you can see while it is installed. The mark is chiseled across between the center hub and the outer ring. Rotate the engine with a 3/4 wrench and look closely for the mark. If the mark on the hub is not aligned with the mark on the ring then it is slipped.
Can you remove a harmonic balancer without a puller?
Most vehicle engines are now equipped with a pulley that holds the harmonic balancer apart from the center bolt. To remove the pulley, you need to rotate it a little with a screw driver’s help and pull it out using a pickle fork. You might not need the pickle fork; you can do that with bare hands.
Why would you replace a harmonic balancer?
Over time, the crankshaft harmonic balancer can go bad from constant exposure to chemicals, the elements, or from old age. Signs that your crankshaft harmonic balancer needs to be replaced include: The engine is loud and you feel vibrations coming from your engine.
Harmonic Balancer Replacement Cost Guide 2022 (Updated)
In order to balance the engine’s harmonics, the harmonic balancer is fastened to the front of the crankshaft. A serpentine belt is driven by two basic parts: the first is a heavy machined inner cast component, and the second is an outer cast piece that is driven by the inner cast piece. A large rubber ring connects the two pieces of furniture together. Replacement is quite straightforward if you have the right tools, however getting to them can be difficult. Remove the serpentine belt, followed by the central bolt that keeps the balancer in place, and finally the rest of the components.
Cost of Harmonic Balancer Replacement
The cost of replacing a harmonic balancer for the majority of automobiles is around $200 on average. The cost of replacing the harmonic balancer is determined mostly by the kind and model of the vehicle, as well as the type and brand of parts that are utilized. To give you an idea of what I’m talking about, below are some exact projected expenses for some typical automobiles based on a $100 per hour labor rate: The labor time for a 2009 Toyota 4Runner with a 4.7-liter engine is expected to be roughly 0.9 of an hour on average.
The total cost of replacing the harmonic balancer would be approximately $251 if OEM components were used and approximately $201 if aftermarket parts were used.
- A factory replacement component costs around $84 whereas a Dayco part costs approximately $46, depending on the manufacturer.
- The expected labor time for a 2000 Ford Expedition with a 5.4-liter engine is around 1.4 hours, according to the manufacturer.
- The total cost to accomplish the project would be around $453 if OEM components were used and approximately $185 if aftermarket parts were used.
- A factory replacement part costs around $277, while an Uro replacement part is approximately $49.
What Does Harmonic Balancer Do?
The harmonic balancer’s primary function is to absorb and moderate the vibrations caused by the crankshaft. All of the numerous periodic forces of piston movement and cylinder firing can reverberate throughout the length of the crankshaft’s axis of rotation. It is possible that this will result in magnified harmonic vibrations at various engine RPMs and loads; the harmonic balancer absorbs and reduces these harmonic vibrations. The second function of the harmonic balancer is to send the spinning force of the engine to the drive belt, which allows the engine accessories to be operated.
In the majority of cases, a harmonic balancer fails due to degradation or separation of the rubber ring, which allows the two cast components to partially or completely separate from one another. This has the potential to lessen the dampening effect and produce alignment issues with the belt.
Other Related Parts That Might Be Recommended
The replacement of the front crank seal, which prevents oil leaks where the crankshaft protrude through the timing cover, is perhaps the most often recommended supplementary service procedure. If there are any indications that the crank seal may be leaking, it would be best to replace it while the harmonic balancer is already out of the way. The additional work time is generally only a few of tenths of an hour, and the cost of the part is quite low in comparison. ADVICE FROM THE EXPERTS– Even if there are no visible indicators of front crank seal failure, it is still prudent to replace the seal while it is still accessible as a matter of preventative maintenance.
It is recommended that when a front crank seal is changed for an oil leak, the harmonic balancer be examined and replaced if necessary.
Any flaw in the sealing surface can inhibit efficient sealing and result in a leak.
If a harmonic balancer is being changed because of a belt alignment problem, it is possible that the belt has been damaged.
Other symptoms include the failure of the rubber ring on the harmonic belt tensioner, which can cause the main belt drive to run in a less-than-perfect circle, requiring the belt tensioner to operate continually in order for the belt circuit to function properly, and the main belt drive to fail completely.
A faulty belt tensioner can occasionally be caused by a problem with the harmonic balancer.
FAQ
What is the first indication that a harmonic balancer may be malfunctioning? Normally, there would be belt noise when the engine was first started. Other factors are more frequently responsible for this symptom, but it is one in which the harmonic balancer should be examined. Is it safe to drive if the harmonic balancer is not working? It is possible, but there is a chance that it will cause the serpentine belt, which normally operates the water pump and power steering pump, to come undone. As a result, driving would become difficult, and the engine would overheat rather quickly.
A little more than an hour is required for most engines.
Harmonic balancer replacement
The majority of do-it-yourselfers can replace a harmonic balancer themselves provided they follow the proper procedures. The technique for replacing the harmonic balancer is simple if you have the correct tools. The procedure of replacing a harmonic balancer is divided into three steps. In many situations, removing the central crankshaft bolt is the most difficult element of the process. You’ll need a 12-inch drive size socket as well as an impact wrench with air, electric, or battery power for this.
- This is due to the fact that when you apply force to a huge breaker bar, the engine will revolve.
- Using a holding tool to keep the crankshaft from rotating is the second option to consider.
- Another option is a big offset socket that is designed to fit into a hex slot on the harmonic balancer’s circuit board.
- Remove the crankshaft center bolt from the harmonic balancer in the first step.
- THIS IS EXTREMELY IMPORTANT!
- The outer pulley ring will easily be pulled away from the rubber isolation ring using this sort of puller.
- You’ll need a different sort of pulley to grip the spokes of the harmonic balancer if your engine doesn’t have threaded holes, which may be found here.
If you see this sort of wear groove, you have two options: either replace the harmonic balancer with a new part or add a harmonic balancer sleeve to protect the harmonic balancer.
Install a harmonic balancer sleeve
Providing they follow the proper procedures, the majority of do-it-yourselfers can replace a harmonic balancer themselves. It is necessary to have the proper tools for replacing a harmonic balancer. The method of replacing a harmonic balancer consists of three steps. The removal of the central crankshaft bolt is often the most difficult element of the process. A 12-inch drive size socket and an impact wrench with air, electric, or battery power are required for this task. However, it will be far more difficult if you do not have an air impact wrench on hand.
- Because applying force to a big breaker bar will result in the engine rotating.
- To keep the crankshaft from rotating, the second alternative is to employ a holding tool.
- The harmonic balancer can also be equipped with a big offset socket that fits into a hex slot.
- Removal of the crankshaft center bolt from the harmonic balancer is the first step.
- BE CAREFUL WITH THIS!
- It is simply possible to remove the outer pulley ring from its rubber isolation ring using this sort of puller.
- You’ll need a different sort of pulley to catch the spokes of the harmonic balancer if your engine’s cylinder heads don’t have threaded holes.
- If you see this sort of wear groove, you have two options: either replace the harmonic balancer with a new part, or add a harmonic balancer sleeve to protect the harmonic balancer.
Inspecting and Replacing Harmonic Balancers
A harmonic balancer is an auxiliary drive component that is linked to the crankshaft of an engine at the front end of the engine’s front end. The harmonic balancer’s primary function is to decrease engine vibration, and it also functions as a pulley for drive belts in many instances. Harmonic balancers are referred to by a variety of names, including damper, crankshaft pulley, and crankshaft balancer, amongst other terms. Even while balancers do not appear to wear as rapidly as typical idler pulleys or belt tensioners, they do wear and must be replaced at some point.
- Damage to the rubber ring that connects the inner hub to the outer ring can be seen clearly in this photo. This rubber ring is subjected to extreme circumstances induced by engine harmonics, as well as heat, cold, filth, chemicals, and oil
- It is also subjected to extreme temperatures. Cracking or bending of the balancer hub or outer ring that is clearly visible
The front main seal is leaking.
- Specifically, the oil seal and timing cover are corroding and eroding away at the metal of the harmonic balancer, enabling oil to pass through.
Specifically, the oil seal and timing cover are corroding and eroding away at the metal of the harmonic balancer, which allows oil to pass through.
- Because of rubber breakdown, there is a visible wobbling of the outer ring on the inner hub.
Belts that make a lot of noise
- Drive belts that are slipping or screaming, belt damage, or increased belt wear are all potential problems.
Performance of the engine
- Late-model engines fitted with electronic ignition exhibit poor performance and an inconsistent idle.
Vibrations in the engine that are excessive It is recommended that you examine the balancer as well as the other front end accessory drive components if you are experiencing any of the problems listed above with your vehicle. If any of these symptoms are present, we recommend that you get your vehicle’s balancer replaced.
Harmonic Balancer Repair Sleeve
Despite the fact that the timing cover crankshaft (front) seal is significantly easier to repair than the rear main seal, it can provide its own unique set of obstacles throughout the replacement process. In many cases, getting to the seal is time-consuming, and you will almost always end up removing the timing cover in order to do so. Since you are already at the front of the motor, it is a good idea to go one step further and change the timing chain set while you are still at the front of the engine.
- When removing a front timing cover seal, it is all-too-common to forget to check the hub of the harmonic balancer for wear.
- It may be difficult to believe, but the seal has the ability to carve a tiny groove into the hub of the balancer when it is closed.
- It is not due to a poor seal in this instance.
- The good news is that the harmonic balancer can be quickly and simply fixed using a kit that typically costs less than ten dollars.
never pry the damper off
As a first step, make use of the required tool, known as a puller, to remove the harmonic damper from the system. This tool operates in the same way as other pullers, with bolts connecting it to the harmonic balancer. Pulling the balancer off the puller is accomplished by the use of a jackscrew, which is equipped with a protective plate, during operation. It’s never a good idea to try to wrench a harmonic balancer off its crankshaft. There are several engines developed in the last 20 years that do not have a keyway in the balancer or the bottom of the crankshaft.
- This stage must be completed by using an installation tool while reinstalling the harmonic balancer in order to bring it to a close.
- By pushing the crankshaft into the end of the balancer, you will very certainly destroy it and hurt the crankshaft.
- To determine whether or not the rubber dampening ring is still supple and spring-like, check its condition if the design permits.
- This is the moment to examine to see if there are any fractures in the harmonic absorption substance or if any pieces have fallen out.
- In the vast majority of cases, if not all, of the applications, the sleeve is fitted to the hub with an interference fit of around 0.002 inch.
As a result, it will be necessary to press forward. Because the sleeve wraps around the outside diameter of the hub, there is no interference with the keyway to the snout when the hub is rotated.
install with lubrication
While the timing cover is still off, trial-fit the balancer with the sleeve that was fitted through the new seal to ensure that it works properly. Engine oil or engine assembly lube (if you have it) should be used to lubricate the lip seal and the hub of the balancer prior to performing this procedure. Assembly lube is my preferred choice since it is thicker and will remain in place better than oil. You do not want to trial-fit or assemble the final assembly with a dry seal and hub, since this can cause problems.
Ask the business to search up the part number using the engine program on their computer.
Providing you have a cooperative sales representative, that individual will draw out a couple of different part numbers, which you can then match up to the specs you want.
How to Remove an Automotive Engine Harmonic Balancer
This first goal is to assist in the balance of the engine, as suggested by the name. However, it is also responsible for assisting the engine in maintaining momentum while running, and it is also responsible for driving the serpentine belt through a pulley or the outer ring of the harmonic balancer, as indicated by the name. Many internal engine services, such as timing cover gasket replacement, timing belt, timing chain replacement, and water pump replacement, necessitate the use of this technician.
What goes wrong?
A harmonic balancer is made up of two independent parts: the mass, which is connected to the crankshaft shaft, and the energy dissipation element, which is separated by a rubber insulator. The mass is attached to the crankshaft shaft by a bolt. Because of the tension and pressure put on the harmonic balancer, the unit may break or detach from the rest of the system. If the front main seal breaks, an oil leak will result, and the balancer will have to be removed in order to be repaired. The balancer in the image below has entirely disassembled, and the rubber insulator is no longer there.
- It assists in maintaining the engine’s momentum
- It reduces engine vibrations
- It drives the main serpentine belt
- And it is utilized by the front main oil seal. It is possible for the engine to fail, creating noise.
Let’s get started
Engine momentum is maintained by this component; engine vibrations are reduced because it drives the main serpentine belt; it is utilized by the front main oil seal Failure of the engine might result in noise.
- In order to remove the serpentine belt, first remove any plastic shields that are blocking access to the balancer, if there are any, and then release the tensioner on the belt tensioner. Throughout this time, inspect the condition of the belt in case it has to be replaced during the process. It is necessary to remove a pulley that is bolted to the front of the balancer in some vehicles before the crankshaft bolt can be removed and the puller fitted. In this case, an air impact cannon is used to assist in making the process simpler. It may also be removed in the normal manner, but the engine must be prevented from turning over through the flywheel starter access port
- The balancer pulley is seen below, which is fastened with three bolts (equally spaced) and washers. You want to make sure that the bolts are inserted far enough that they will hold correctly when the puller is employed. For the best results, it is recommended that you apply a tiny quantity of lubricant to the puller’s threads before using the tool. (Please keep in mind that certain dampeners are not press fit and can be removed without the use of a puller).
- Tighten the puller using an air impact wrench
- You may hear a little pop as the dampener begins to move away from the crankshaft, which indicates that the puller is in good operating order. As the balancer is removed from the end of the crankshaft, the push bolt on the puller will become easier to turn. It’s important to keep your hands on the balancer as soon as it becomes loose since it might be rather heavy
- Once the dampener has been removed, there may be an oil varnish film on the frontsealing surface that must be cleaned with carburetor cleaning or fine sandpaper before the dampener can be reinstalled. Keep an eye on the state of the woodruff key slot, since if the balancer was loose, the slot would be damaged
- And The harmonic balancer installation utility shown below is used to reinstall the harmonic balancer. Never smash the balancer back onto the engine, as this will cause damage to the crankshaft thrustbearing. After any repair work has been performed, such as replacing a front main seal, heat the balancer in an oven to 190 degrees Fahrenheit to assist in expanding the dampener and making installation easier. Once this is completed, apply a little quantity of oil on the sealing surface of the balancer. Align the balancer woodruff key slot on the crankshaft with the keyway on the crankshaft and tighten the key into position. This allows the balancer hub to slip on the crankshaft snout a tiny amount while maintaining contact with it. The installation tool for the balancer should be wound into position
- Once again, a tiny quantity of lubricant on the tool threads will assist in the operation. Tighten the balancer installation tool using two wrenches, retaining the screw while tightening the huge jam nut
- Repeat this operation until you no longer feel the balancer sliding inward. Once the installation tool has been removed, apply sealer to the centerbolt and tighten it down to assist prevent oil leaks
- This will aid in the prevention of oil leaks. Remove the bolt and tighten it to the manufacturer’s suggested torque standard (typically 130 to 150 pounds). Replace any worn or damaged serpentine belts as needed, and then start the engine to listen for any unusual noises or oil leaking

What Is A Crankshaft Harmonic Balancer?
The harmonic balancer, which is connected to the crankshaft of an engine, acts as a pulley system for your drive belts and helps to lessen overall engine vibration when the vehicle is in motion. With rubber damping vibrations and a mass to counteract the acceleration that your car will experience, the balancer is able to absorb vibrations and provide you with a smoother ride than you would otherwise get.
Common Signs And Symptoms That You Need to Replace A Crankshaft Harmonic Balancer
- When the engine is running, it vibrates. The engine makes a loud humming noise. When the engine is accelerating or running at fast speeds, it creates noise.
How Important Is This Service?
The harmonic balancer serves as a shield for your crankshaft, absorbing some of the incoming vibrations and directing them away from the engine. If it fails, your crankshaft is vulnerable to significant damage, therefore if you suspect your automobile is exhibiting any of the symptoms listed above, contact a professional for an examination as soon as possible.

| So I had an incident with my HB on my 1972 Javelin 360 4bbl 4 spd. No biggie I thought. Ordered a new HB from rockauto, dorman594135. It arrived, I painted it to match and went to install it today only to find out it’s a 4 bolt center mount. mine is a 3 bolt center mount. So angry as I was I thought no problem I guess I’ll spend another wad and get a 3 bolt, only to find absolutely zero listings for one. I’m at a loss for words, my car has 10,400 original miles and I can’t even use it. . Has anyone ever encountered this situation and what was your solution to the problem? I have an extra 74 360 with a pulley that will bolt on to the HB but obviously it has different WP (long nose) this is just going to cause me more problems than I have time for. Suggestions please and thanks | |

Harmonic balancer replacement
It’s possible that you’ve seen a circular device at the front of the engine bay, which is normally comprised of metal and rubber. If you’ve ever peered into an engine bay, you may have spotted this device. The harmonic balancer is located here. The harmonic balancer in your car ensures that the engine runs smoothly and that harmonic vibrations are minimized. If it fails, you may hear a minor noise or, in the worst case scenario, the engine may be severely damaged. The latter is ideally avoided, but if you notice any signs that point to the harmonic balancer malfunctioning, you should have an AutoGuru expert technician check things out and get the balancer replaced as quickly as possible.
What is a harmonic balancer?
In an internal combustion engine, a harmonic balancer is an external component that is attached to the end of the crankshaft and is placed at the front of the engine. Its duty is to lessen the amount of vibration generated by your engine. It is also utilized as a pulley for drive belts that power various engine accessories such as the alternator, power steering, and air conditioning in the vast majority of automobiles. Whenever an engine cylinder is fired, there is an application of force to the piston.
It is at this point that the harmonic balancer is utilized.
In addition, the harmonic balancer serves as an external counterbalance to the revolving shaft.
Symptoms that a harmonic balancer needs replacing
- When the engine is running, there may be a significant vibration. There’s a strange noise coming from the engine
- Complete failure of the engine
- The rubber mount can be seen to be fractured, and the harmonic balancer has detached from the rest of the unit. The timing markings are not in sync with one another. There has been a fallout with the balancer off of the engine.
How is a harmonic balancer replaced
- The belt tensioner bolts are released in order to alleviate the stress on the accessory belts, and the belt is shifted away from the harmonic balancer to do this. Taking off the center bolt on the harmonic balancer is a good idea. In order to disconnect the harmonic balancer from the crankshaft, it is necessary to employ a pulley. The harmonic balancer has been replaced, and the center bolt has been tightened. Reconnect any accessory belts to the harmonic balancer
- Tension is applied, and the belt tensioner bolts are tightened once they have been disconnected. Take a test drive
Tips to remember
It is important not to damage other engine components while removing the harmonic balancer out of the engine.
This includes the plastic timing belt covers. Ideally, you should be removing the component with a harmonic balancer puller tool that has been properly created for the job. Have your harmonic balancer checked out by an awesomeAutoGurumechanic as soon as possible if you feel it is defective.
