it'll sound like a hollow tapping sound while rotating.
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
It shouldn't make noise. If it does, replace it!
Hard to say. However, if the "rubber gasket" you're talking about is the center bushing on your harmonic balancer, that could throw your Harmonic balancer out of balance. This could easily make it shake to beat the band which in turn could be the knocking noise you're hearing. I suggest you get it looked at immediatly. If that is what happened, your engine won't survive long.
unless real bad usaully do not make a noise but give bad vibration.
To remove the harmonic balancer from a Nissan Maxima, first you need to removed the center bolt. After that, you can use a puller to remove the harmonic balancer. Before you do this, make sure you disconnect the battery and remove the drive belts.
The balancer is made of 2 pieces That have a rubber piece in the center of them that hold the balancer together. If the balancer comes apart YES it will knock / make noise and the engine would vibrate/shake. You would be able to move 1 piece of the balancer with your hand if that was the case. Check it.
loosen the center bolt and get your self a harmonic balancer puller just make sure you loosen the center bolt enough but not too much but you need a balancer puller.
It could be your harmonic balancer.
first remove serpintine? fan belt then remove large bolt in middle of harmonic balance. this bolt usually has left hand thread next with a harmonic pulley ,puller, remove harmonic balancer.when removing this, there is a key in the balancer and shaft if a new key did not come with new balancer,make sure not to loose the old one install new balancer with key.use the bolt to pull balancer up tight where it needs to be and use proper torque on bolt
Yes if rubber isolator is bad
It could be or it could be the balance shaft or numerous other things. Take it to a shop and have them check it out for you.
Pull the belts, remove the center retaining bolt then use a harmonic balancer puller to remove the pulley. Make sure you use a disk that will protect the threads of the cranshaft when you tighten the puller.
