Campy Centaur crank bolts - no grease?!?
Kovie
and the manual emphatically says to NOT grease the crank bolts. Is this a
mistake, as I've heard that all threaded metal parts must be greased? Could
they have meant the tapered spindle, and accidently used the word "bolts"?
The sentence preceeding this admonition actually said to clean the spindle,
so I can see how there might be a mistake. Or is there something about Campy
Centaur bolts and BBs that makes greasing the bolts unwise? Could this be
because grease would make it easier to overtorque the bolts and possibly
snap/strip them? What if I use a torque wrench, does that make it ok to
grease the bolts?

It's either a mistake or they mean don't grease if using threadlock.
Experts always advise using grease on the bolt threads and under bolt
heads. Do the washers as well.
Greasing the spindle is a different matter: a very controversial subject.
Find previous discussion on that via Google Groups.

The Campy crankbolts have some sort of threadlock (Loc Tite?) on them by
default. I always grease them though, the required torque is so big i can't
see them getting loose that easy. Trying to get out a stuck crankbolt when
using no grease is a much bigger risk IMO. Btw i also use some grease on the
spindle and always wear a helmet...

Heh.
I suspect the threadlock is the equivalent of spoke prep - it allows
some measure of safety in the event of an under-torqued crank bolt
(since the bolt will be less likely to come completely loose). But if
the bolt is to be torqued properly, I'm with Ronald - grease it and
"fuhgeddaboudit".

Dear Kovie,
I wouldn't use a torque wrench to grease the bolts.
A grease gun or even your finger will be much more
convenient.
Helpfully,

Gresae the bolts. Grease the faces under the bolt heads.
Grease the tapers. Grease the male side of the chainring
bolts. Grease the BB cups. Grease the pedal threads.
And when Campagnolo says you _need_ to buy new "ten speed"
chainrings when upgrading from nine speeds, that's also not
true. The only advantage we can see is "style points" for
having "ten speed" hot stamped on your chainring, if that
interests you.

that. Can't wait for them to grunge up and peel off and mess up the look of
my new bike.
Btw, I ended up greasing everything but the BB and taper. I used anti-seize
on the BB & shell threads, and wiped off the existing grease on the tapers.
However, there was still a very thin layer remaining on them, so it wasn't
completely "dry". The cranks went on fine.

Okay, I see this an awful lot. I haven't slept in three days, so sick

I use threadlock on the bolts on their second tightening, and don't
touch them after that. I use anti-seize on the tapers because they can
corrode solidly onto the cranks such that the crank puller can't remove
them - I've ruined a set of cranks that way.

Your of the term 'outside' is offensive to us differently-included
