Hello – removal of the harmonic balancer bolt is counter-clockwise. Be sure to use a flywheel block or pin to prevent counter-clockwise engine rotation, which could cause engine damage.
Which way does the bolt turn on a harmonic balancer?
“Right hand thread” means you turn CLOCKWISE to tighten, COUNTER-CLOCKWISE to loosen.
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.

10 signs of stock elastomer harmonic balancer wear. Cracked, bulging or missing rubber. Harmonic balancer wobbles. Separatation between the hub and outer ring. Timing marks slipped.
Why does my crankshaft pulley wobble?
If the fan-belt pulleys that bolt to the harmonic balancer are dismounted, bent, or distorted, it may cause the crankshaft pulley to wobble. … Sometimes, some dirt may get trapped under the pulley. Furthermore, the crankshaft pulley tends to wobble if it isn’t appropriately torqued.
Can a bad harmonic balancer cause transmission problems?
While reading online about potential damage caused by a bad harmonic balancer, I found that it can seriously damage your transmission.
Is a harmonic balancer the same as a crankshaft pulley?
Similar they are both Front Crankshaft Lower Pulleys but a Harmonic Balacer has a Rubber insert damper and is weighted to help cancel out Engine vibration whereas a normal Crankshaft pulley is just a solid steel pulley.
How long do harmonic balancers last?
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.
How do I know if my crankshaft pulley is bad?

How does the harmonic balancer on a car work?
The circular device, made of rubber and metal, is bolted at the front end of the crankshaft to help absorb vibrations. It’s usually connected to the crank pulley, which drives accessories like the air conditioner. The rubber inside the pulley is what actually absorbs the vibrations and keeps them at a safe level.
