Wow. Not the first I've heard of though. What indication do you get when it fails? Makes me consider buying a new one for my build

[JasonY]

I took one off of my friends 97. No signs of failure, no noise, nada. Put it on the garage floor and it came right apart when i went to pick it up.

Anytime i tear down an engine, it goes back together with a new OEM pulley if its the original still on the car.

They should probably be replaced every 60k, at the very least 120k. They have caused more damage than any aluminum pulley. I had zero notice when mine split, lucky no damage, others not so lucky. 3sx pulley ftw!?

[mb3000]

Absolutely zero signs of warning. Simply came apart on me when I went to remove it from the engine. Car has roughly 128k.

I did a study on 3si years back. They seem to fall apart about 120k mark or sooner. Depends on the environment. I will trust my car with the aluminum pulley until we get to 5-600hp. Then you need to think about getting a real dampener. It will cost you about 800 bucks, or get a brand new stock pulley. I can tell you this, old stock pulleys cause more damage than aluminum aftermarket pulleys.

[Jimvr4]

Yeah there's a thread on an aftermarket balancer right now for like 650-800.

lol, memories...mine fell off in the exact same fashion long ago, right about 150k miles if i recall correctly :wink:

I'm fairly certain that mine is still the original pulley. 21 years old and 220,000 miles. You guys are getting me worried.

May need a guru to advise if the non-turbo ones are made the same?

Yup no difference apart from either v belt or robbed belt for PAS . :)

I'd just get an aluminum pulley for your NA. It probably is something to be concerned about since it’s that old.

[BlackStealth]

Mine failed at 78k, part was 18 years old and gave a squeaking noise at idle. I mistakenly thought the noise was caused by A/C belt or Alternator belt but when I could not get rid of the noise at all I discovered the defective pulley had a slight wobble to it. The wobble would rub into one of the belts and created a squeak.

The rubber portion failed at 18 years.

I replaced mine at 150k with aluminim. It had no issues. It was still in one piece, solid. Or at least it seemed that way.

[Hard AttacK]

183k....-_- guess I'll be buying aluminum!

[Jimvr4]

I just received my new stock balancer. Should be good for another 18 years LOL

this is only true because EVERY 3/s came with one, but not every 3/s has 500+ WHP and is running a solid pulley. i get where you're coming from, paul...but you kinda skewed the facts a bit.

[jras312]

Where is the cheapest source, cherry hill?

[Jimvr4]

I went with Ninja since he ships priority mail for free. It was $250 shipped from him and showed up in about 3 days.

Yeah I thought I left that a little vague.
