I need it for a E320 1998. There's some kind of vibration and I can't seem to ID all the pulleys there. MB's look so much different from the toyotas I'm use to. The dealer is telling me it's a few hundred but I think he is talking about another pulley from a diagram he gave me. If you can give me a picture and ID the pulleys there, it will be great. This is for my dad and I'm trying to help him out.
Thanks everyone, first post here.

I found this picture in a pdf file.

The pulley that's circled is making the noise. Can anyone ID this please? And if you don't mind, can you label the other pulleys there? Thanks again.

That's your belt tensioner. The part costs about $170.

There's posts about the harmonic balancer recall in the forum, so check to see if yours is included. The HB is behind the main pulley at the bottom of the engine and the number is stamed into the outer face of it. If your number matches one of the ones below, have the dealer replace it -- it's free, particularly since the vibration could be coming from there. That's a common symptom of the failing HB. Since the dealer has to pull the belt and other items to get in there, they'll probably do the tensioner for the cost of the part. But yeah, the tensioner is another culprit as well, but it's usually lots of free play and noise, not just vibration.

Okay, here's the two part numbers for the suspect HBs:

A112.035.00.00

and

A112.035.06.00

I breathed a sigh of relief when I saw mine was 08.00.

Take care and enjoy the ride,
