RE: 4000csq belt squeeking at start

[Aleksander Mierzwa <alex@matrix.com.pl>]

Well, I always loose all alternator bolts when attempting to tighten the
belt. My observation is that the adjusting gear is made of way too soft
material - both times I tried to tighten the belt using the gear I
simply could not apply enough torque - the teeth were breaking way
before achieving correct belt tension. On my 87 5KT the AC comperssor
has indentical adjusting mechanism - I found both the alternator and AC
compressor much easier to adjust using simple pry bar. I don't know,
maybe the bolts I bought weren't OE quality, but d*mn, they costed me 7
bucks each. I like the PS pump adjusting mechanism - you aren't in hurry
because you must keep the pry bar/wrench at correct torque. And you
could easily and precisely measure the belt tension using dynamometer,
if only Audi provided the specs.
