Does a harmonic balancer increase horsepower?
A harmonic balancer is designed to keep crankshaft torsional vibrations in check that occur when the engine is running. So, it doesn’t matter what kind of change you make to the engine, adding more horsepower will change its harmonics.
What problems can a bad harmonic balancer cause?
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.
Can you drive without harmonic balancer?
And because the belts that go around the crankshaft pulley run all of the car’s accessories, without the harmonic balancer you’d have no air conditioning, no power steering, no alternator and no water pump. And without it, you can do damage to the crankshaft and the engine bearings. So you really do have to replace it.
What does an aftermarket harmonic balancer do?
The function of the harmonic balancer is to reduce the amplitude of the torsional vibration peaks to an acceptable level. Most OEM harmonic dampers are not designed to cope with the rpm and BHP levels experienced in competition.
How long do harmonic balancers 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. This is a good example – because it’s got such a massive piece of rubber – you can see the rubber literally tears apart into two sections.
Is crankshaft pulley same as harmonic balancer?
A harmonic balancer is a front end accessory drive component that is connected to the crankshaft of an engine. Harmonic balancers do have many names, though, such as damper, crankshaft pulley and crankshaft balancer, among others.
What are signs of a bad harmonic balancer?
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.
Why is my harmonic balancer wobbling?
Excessive belt tension. An over-tightened belt may cause crankshaft snout runout and harmonic balancer wobble.
How do I know if my harmonic balancer has slipped?
Re: Harmonic balancer / how to check if it’s slipped 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.
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. Turn off the ignition.
Is a harmonic balancer necessary?
Without the harmonic balancer there is a high risk your crankshaft would crack or a serpentine belt would be thrown off track. A simple way to think of the harmonic balancer is like a massive stress reliever.
Can a bad harmonic balancer cause overheating?
The constant twist/untwist movement causes the rubber to heat. The most damaging cause would be engine overheating. That extra heat can dramatically accelerate; deterioration of the rubber isolation ring.
Does an internally balanced engine need a harmonic balancer?
Generally speaking, internal balance is the better option. External counterweights can cause the crankshaft to flex at high rpm. It requires a new crankshaft, harmonic balancer, and/or flywheel or flexplate. You may also need to clearance the block for the larger counterweights.
How hard is it to replace a harmonic balancer?
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.
When should I upgrade my harmonic balancer?
Reasons to Upgrade Obviously, if your harmonic balancer is damaged, it should be replaced. But there are also other reasons to consider an upgrade. Stock harmonic balancers are designed to work best with a stock rotating assembly, spinning at relatively low RPM’s.
