I changed my harmonic dampener just in time *Pics & Video*

Here's a video. Let me know what you think.

YouTube - DSM Engine squealing

Do not turn your crankshaft backward during the process. It's very easy to skip teeth when the engine's not running.

Well never got a chance to video the balancer/pulley movement but...took out the 4 bolts and wahla!!! you guys were right...fell apart in 2 pieces. Installed new crankshaft pulley/balancer and we were back in buisness. Car is running and idling much better...had bad vibrations and almost sounded like it was missing..all seems good now. I guess we dodged a bullet for sure!!! The lower timing cover is prety scared up but didn't have a replacement so that will have to come later.


Thanks to all for the help
Scott

oh yeah...$100 instead of $500-$1000

question for the gang here.

upon being recommended to read this thread because of an eerily similar issue on my car, i ran across this possible cheep, and permanent fix...

aluminum crank pulley...

thoughts?

That pulley does not have a harmonic balancer. I wouldn't touch it. There are tons of threads about underdrive pullies that you can read.

 

[_95AWD_]

its more a dampner then anything, the stock piece that is.

the last thing i would imagine doing is underdriveing the accessories, these cars tend have enough voltage issues with a stock set up.

i like that piece because its solid, and offers no rubber seal to ware out over time.

none the less I'll take the car out for a drive today and see if my work last night (belt tension) has fixed my other little issue.

 

[1992awdlaser]

I meant read the threads about underdrive pullies because they too don't have the damper/balancer. I wasn't saying the one you posted is underdriven.

Expect crankwalk within the next few months because you failed to read on what underdrive pulleys do to our cars.

 

[gsxAWDdsm692]

haha I changed mine and the squeaking has gone away. Sometimes...

i said i DONT want to use an under drive piece, i just like the idea of a solid unit, no rubber compound to kill during my wondrous Michigan winters.

ohhh how i hate the tons, and tons, of road salt they put down every year.....

 

[1992awdlaser]

He meant the lack of the balancer/damper even though he said undrive pully. In Syracuse I haven't had a problem due the salt.

 

[crimsondragon]

Regardless that aluminum piece will NOT dampen the vibrations given off the crank. You will damage the bearings and thus crankwalk will ensue as some have experienced. If you want a solid piece, I recommend Fluidampr. No rubber and filled with a special kind of silicone I believe to dampen all vibrations.

A Harmonic balancer is nuthing to toy with. IF you even think it maybe going out, replace that sucker ASAP!
Anyone see Pinks last sunday? One guy's outer ring came off and rolled down the track?
He ended up running anyways, and blew the motor



Wonder if we can get another Fluid dampner Group buy going...

 

[_95AWD_]

ahh, yes....

a fluid-dampner set up....now that i can dig!

my issue seems to be belt tension related....i took it much tighter then i would have liked, but all sounds and noises have gone away for now....

and the OEM harmonic damper looks brand new, the guy i got the car from did a good "freshen up" with this thing.

FYI: To anyone experiencing horrendous belt squeal with properly tensioned, new belts. Even if your harmonic dampener doesn't look bad, old, or failing, it still can be.

I developed a harsh belt squeal on Monday. My belts are new, and adjusting tension didn't help. On a whim, I brought home a Fluidampr from work and swapped that out last night. Wha-la. No more belt squeal. Upon inspection, my OE dampener looked fine. No rubber cracks or separations. Just goes to show that it doesn't have to look bad to be bad.

I am having the same problem as you were. Except I have all new belts and brand new OEM dampener and it still squeals at startup. It's so ####ing annoying that I can't figure out what the problem is.

 

[99gst_racer]

Well, my belt squeel is back. It's only on cold start-ups and only lasts for about 30 seconds, but it's progressivily getting worse, and it's annoying as hell.

I have a brand new Fluidampr, a new alternator, and a belt with about 900 miles on it. Is is possible that I over-tensioned the belt, causing the bearings in the alternator to wear excessivily? Thoughts?

Well my squealing startup has gone away because well, my timing belt snapped. I'd check that and avoid what I'm going through now.

Damn, that sucks Kevin. Any damage to the head?

Change it before it breaks apart, mines did but it didn't mess up anything, thank god

 

[gsxAWDdsm692]

idk yet. I'm gonna put on a new water pump and timing belt tensioner as well as a new balance shaft and timing belt and try and start it up just for shits and giggles. Maybe I'll get lucky. 10% chance. How's your car comin' along Ricardo?

No damage to the head, but..... James

hahaha nice one James. Atleast I'll have some fun Saturday at the meet

I think that is where I messed up. My old crank pulley fell apart and chewed the lower timing belt cover up and I ignored it. The squealing at startup was probably my timing belt rubbing against the cover. I ignored it too long and that combination with what was probably an old timing belt leaves me ####ed in the ass


NOTE TO PEOPLE THAT HAVE EXCESSIVE SQUEALING AFTER THEIR CRANK PULLEY FALLING APART:

Check out your timing belt.

 

[VETTE_50_TH]

Hahaha. I thought you would like it. So did you get it fixed then or what?

Verified mine last night. I pulled the alternator belt, the squeeling went away, and my idle improved. So it's definitely either the alternator or the belt.

Question: What is the length of the alternator belt for our cars? The one I had on my car is stretched, so I wouldn't trust it's current length, and the boys at Autozone sold me a 38.5" belt (that's what their computer says our cars take). But it seems to be about an inch short. I'll exchange it today for a 39.5" Gatorback, and see if it still squeals.
