Is the rubber that separates the middle of the pulley and the outside deteriorated in any way?

Have you tried another pulley?

Those washers need to be there. They keep your timing belt from getting chewed to pieces.

Possibly a missing or damaged woodruff key?

Well I just posted a similiar thread but it got closed so now I have to bring back this old thread. Here is the original post.

When I took the one off of my new b18b1 motor, we had to get a breaker bar to take it off. It was on tight. The one on my original motor came off with ease. I switched it over to my new motor and torqued it to 130lbs. Now when the car runs, I can see it wobbling and it even rattles some at idle. When the car revs up, the rattling noise goes away. Is this something as simple as changing the harmonic balancer or could it be something worse???? And when changing it with the engine in the car, how do you keep the crank from moving?? Put the tranny in gear?? Thanks alot

one thing I read that I was supposed to do was put oil on the end of the bolt when installing it. At the time I did not know this and didnt do it. Could this cause it to wobble? Also what does the woodruff key look like?? Its been a few weeks since I changed the pulley and I dont remember what all I did? Thanks

one great thread of information is better than two mixed threads with information, which could be one reason(s) the previous thread was closed.

take the pulley back off and check for the key, if thats there and it still wobbles then it is a bad pulley, end all, just like they told you in your locked thread. god.

No, they didnt say anything about it being bad, they just said check for the key. BTW, its NOT A PULLEY!!!!!!!!!!!!!!! Its a harmonic balancer FYI! Can you answer this question, what does the "key" look like???

The OEM crank pulley is the harmonic balancer, so it is safe to say their names can be interchanged.

Let's keep it mature now... yeesh.

It's an underdrive pulley and a harmonic balancer. Same difference... no need to argue about that.

The key looks something like this:





It's a small rectangular piece of metal, that fits in a cut out key way on both the crank and pulley, which keep it aligned in a certain position. Check to make sure it's there, then make sure you have the concave washers installed around the timing belt gear, and if all else fails, your pulley might be out of round or no longer balanced.

Even if the woodruff key is missing, it wouldn't cause the pulley to wobble - the pulley has nearly an interference fit with the crank snout. I'm betting on the elastomer in the dampener has gone to crap causing the pulley to wobble.

Thanks for the logical replies guys. I appreciate it. Im beginning to wonder if I installed the key. I dont remember anything about it being on there. It was the first time I had ever replaced a harmonic balancer so I didnt even know to look for that. Is it something that sits on the crank that aligns the harmonic balancer??? I definitely dont remember that if it is. I do remember putting the washer back on but I hope I put it back on correctly.
