Harmonic balacer making noises? help?

ok, i just finished installing my s/c on my 95 mustang gt. I am running 9 lbs of boost on stock internals. I cranked her up, and she started making some noise which sounded like it was knocking. But under further investigation, it looks like it is the harmonic balacer off the crank....It wobbles a little bit and Im wondering if maybe its the seal inside thats making it wobble a bit. How can I fix this problem? Do i need a new harmonic balancer? Or what does the balancer function as?

Any answers or advice would be greatly appreciated

the balancer is not rebuildable. if it comes apart completely while you are driving, it can have a devastating impact on the motor. replace it now before it becomes a real problem. i would strongly recommend against replacing it with a stock one also. my recommendation from first hand experience is romac all the way. i just got my second romac off of ebay brand new for $100. (normally go for around $270-$350)
 
The balancer quells torsional vibration. Follow above advice and replace ASAP if you think it is bad.

There is an inner ring which is bonded to an outer ring (which has your timing marks) and an elastomer joins the two. If the outer rings slips, torsional vibes will start to rip the motor apart.

Good luck.

thank for the info, i guess i'll be ordering it this weekend... i appreciate all the help and info.... What can cause this kind of thing to happen? PLease advise!
They tend to wear out simply from revolutions-turned (once the elastomer loses its structural integrity, it fails soon thereafter). Ummm, what you just got done doing to the car can kill them off (9 PSI). LOL :nice:

Best thing to do IMHO is just get a quality unit - with the forced induction, I personally would get an SFI version, even if you dont track the car.

Good luck.
 
i third that comment..lol..if thats a word. honestly though get a new one. i tore up a lot of stuff in my old 93 gt when it decided to fly off, and ruin a few things. costed around 700 bucks to replace everything that got damaged, when it could have only costed 150 or so for a good replacement.
