What seems to be the problem with yours? ...Rubber bonded joint seems good...

Given what you've spent on the rest Charlie, get a new one.
Finding a used one is pretty difficult, find a good one is going to be a challenge

That's what I said to Will last night. Now Kit's trying to convince me to use a 3B pulley and swap over the alternator pulley so it matches. But then Will said they have a tendency to come off at high rpm which is why they changed the design. Then Kit says he knows plenty of 3Bs running 8k rpm... so I dunno.

I guess I'll just have another chat with Will tomorrow and try and make a decision...

Is this what I'm looking for, I've been told I'm looking at spending £500 so this doesn't seem right:

edit: Ah, that's without the dampener so I found this but it doesn't have the ribbed pulley:

edit again: so now I find a damper on it's own, does this go with the pulley above (the first link)?

My main point's were you've done away with the aircon, have a slightly deeper intercooler and the 3B pulley will give a little more clearance as well as being a bit lighter in weight.

If your only running stock max RPM I don't see the problem.

That said you've thrown so much money at it I can see the argument for getting a new one as Alex says.

I suggested it as I have four spare 3B pulleys and your welcome to one FOC, it would get you out of a jam if you didn't want to buy a new one or manage to find a second hand item....

There's plenty of Scandinavian 3B's running 8K RPM....

That's not the correct damper, at least I don't think it is, just fire the part number into Google and see what comes up

**K Simmonds** · 8 April 2016, 20:58

Like I said in my text it's the weekend so there'll be more user's on here who maybe able to help.

**cardcrash** · 8 April 2016, 21:25

I very much appreciate your offer Kit and I'd be happy to go down that route, but I just want to hear Will out on the pros and potential pitfalls of doing this. Perhaps the Scandinavians are doing this, but perhaps their alternator belts keep flying off and they're just happy to bodge them back on and carry on as they were... I don't know... I need more input...

Anyway, Google's no help, so I've emailed Audi Tradition with the part numbers and what I've managed to find and see what they come back with. They've been quite helpful before, just such a shame trying to negotiate their disastrous website. It's like everytime I try to login it says it doesn't recognise me, so I try re-registering and it says I'm already on the system, so then I ask for a new password but that doesn't work so I have to contact customer support where they reset everything and tell me everything should be fine from now on... but I'll get to make one purchase before I'm back in AT purgatory!!

**K Simmonds** · 8 April 2016, 21:35

AT is the the least user friendly site I've ever encountered, completely useless! You have my greatest sympathy in trying to negotiate it, I've used it once and won't ever again unless I have no other option, though it looks like you maybe in just that sort of spot.

If you google the part number you'll find diagrams that show the damper you posted a link to with the associated pulley assembly and it doesn't look right to me.

**cardcrash** · 8 April 2016, 21:39

I went to that audi.7zap.com website and got the part numbers from there, but the damper I found on AT doesn't match the number from 7zap. The Pulley does though.

**K Simmonds** · 8 April 2016, 21:58

Yeah the pulley looks correct to me mate, pity it's not quite what your after, especially as it's only 60 Euro's.

What a bloody ball ache!

Edit. My S2's never thrown it's belt in 30K miles and I don't run it overly tight to avoid stressing the alternator bearings, in fact I've never heard of a 3B chucking it's belt off under normal conditions.

As it happens the only occasion I've heard of an S2 throwing it's alternator belt of was recently on Rusty's ABY....

I do get Will's point that it would be best to keep the belt set up stock but don't see any reason why a 3B pulley couldn't be used if sticking with stock RPM...

**cardcrash** · 8 April 2016, 22:01

Well I emailed AT essentially asking if they have the damper that goes with that pulley or an all-in-one part.

**Error404** · 8 April 2016, 22:20

Audi switched to a multi-vee belt in order to drive a more powerful alternator. The single V-belt can't really transmit enough torque to drive the 120A alternator, the belts slip unless you bollock them up to oblivion.
You will need to drop down to a 90A or 100A unit with the 3B pulley...... not that you will find it any easier to find a good 3B one either!

The RS2 damper is 034105251M

It fits together with the pulley section you linked to, to form the pulley / vibration damper assembly

That explanation makes way more sense to me, thank you for clarifying it Alex,

Oh well, if you have to downgrade the alternator to make a 3B pulley work then you really should stick with the original set up.

Anyone need a 3B damper?

Only joking I'd actually rather keep at least two as spares for my S2,
