Harmonic balancer?

Latest was less than 3 days after I had the serpentine belt replaced then the balancer, all fixed thank you

How long should it take to replace this part, only using jacks at home to lift it?

I have a very loud knocking noise, which I believe is comming from the harmonic balancer. The noise is coninuous from start up. When the engine is not running I can turn the harmonic balancer approx 1/4 to a half turn and it stops making the same noise by hand. Is this a bad balancer? If so before replaing, could this have done other damage I need to be aware of and check before wasting time and money?

Is the bolt that holds the pulley and harmonic balancer on, left handed or regularly threaded?
I am having a heck of a time breaking it loose?
Impact has no effect and it is a 750 ft pound wrench?

I have a 89 buick century and a 91 buick century, would the harmonic balancer from my 89' work on my 91' as a
temporary fix?

I have a 1991 Buick century Limited I have replaced the harmonic balancer 3 time in 2 months and the crank seal twice, The seal popped out. I would like to what is causing this?

The first one was replaced because the center was cracked and made less tension on the belt which caused the battery to die. It worked for about a month, Then the second one started wobbling like it was a defect and now the third one is doing the same like something is bent. Hope this helps on giving me advice on how to fix

I just changed the Harmonic Balance in my 1991 Buick Century and after I put it all back together, serpentine belt and all, my car will not start and was chewing up the serpentine belt. A friend of mine told me to take off the belt and try starting it without the belt, and it still won't start. I even pulled off the new balancer and put back on the old one, and it still won't start. Any suggestions?

Sounds like maybe it's not properly seated on the shaft. If it's not close enough to the timing cover, the interrupter rings on the back of the pulley won't activate the crankshaft position sensor behind the pulley, which would cause the no-start. And maybe the belt is getting shredded by the balancer being out of alignment with the other pulleys.

I have a 1989 buick century, limited, 3.3 engine. The harmonic balancer fell off. The after market or the new balancer they make for the car are a lot thicker. And the mechancic who is suppose to be putting it on, says they don't fit. The balancer that came off the car is about as thick as a pulley, whereas the new ones made for the care are twice as thick. The guy told me the new balancer rub against the oil filter. That made me think back to when I had my oil changed. It appeared to me the new oil filter put on was longer than the one taken off. I mentioned it to the guy who changed my oil. He says that was the filter the book called for. Since it didn't leak, I dropped the subject. Could that be the problem? Have anyone heard of the harmonic balancers they make for that car now, not fitting? Or would you try to find one in a junk yard.

I have a 92 Buick Century, mileage 83598, engine size 3.3. Need to replace harmonic balancer. Having problems getting bolt off. Is it right or left threaded? Suggestions on how to get it off? Already tried impact wrench. Guess air compressor wasn't putting out enough air? Please help!
