[s-cars] timing belt service issues

[Stott Hare]

The serp belt runs has a roller that it passes over between the alternator
and the AC compressor, more inboard/centerline than the other two.  This is
mounted to the AC support bracket and drives the main fan/viscous clutch.
It sounds like that is what the mechanic is trying to describe.

My memory is sufficiently foggy I'd have to check Bentley as to bearing
replacement steps.  It will involve removing the main fan/viscous clutch to
gain access/working room - you unscrew the main fan from the roller (pin
wrench and a 32mm thin open ended wrench). I believe the roller pulley
unbolts to expose the bearing, and that you use a special tool bolt to
remove/pull the bearing off the its mounting boss.

Hope this is enough to jar some bad memories, but it's all I have at the
moment.

So, I'm letting the mechanic do my timing belt on the S6 today.  He just
called to say.the tb is on, but there's a problem.  The bearing assembly.and
his description has got  me confused.behind the fan clutch (?) is shot and
needs replacing, but he can't figure out how to do it without pulling
everything off the car and 4 or 5 hours of labor.plus the Audi price of $260
for this thing.  He said he's pulled a diagram, but doesn't have the p/n
(@#$%^&).  He said it's mounted to the main bracket that everything else
mounts to, but he can't see a way to get at it from behind while it's on the
car, so it would seem it all has to come out.a/c, power steering pump, etc.
which makes me cringe at what else will stop working when that's done.

 

Can anyone straighten me out on what he's talking about and what options, if
any might exist?  I'll spin by the shop and try to catch him before he
leaves this evening, but if you've got some info to help me before I go, I'd
appreciate hearing it ASAP.  Don't have the EKTA link on my laptop.what's
the best one now? .was just looking at that one not but a few months ago.

 

TIA,

 

Steve
