CAMPY RECORD BB problems!

Grease, really!? Hmmmm. I gather the grease helps ease the
installation some, and then also acts as a weather/water barrier?

That's true, but BBs have a nasty tendency to collect water. If you
don't grease those threads, they will soon be firmly held there by rust.

Threaded fasterners should be greased to prevent corrosion and to allow
proper tightening. Torque specs assume a greased thread.

Then all I see loktite doing is making future removal of same Bottom
Bracket virtually impossible down the road. (God, I love these type of
topics/conversations!)

Locktite is not needed with BBs, as a general rule. But heat will allow
the seperation of locktited parts.

I can clearly visualize exactly what facing does for a BB
installation. I assume "what good is achieving proper torque values,
when only 1/3-1/2 of a BB Cup Lip is actually making proper contact
with the frame BB edge?", Correct?

Yes, but it's also important for proper alignment of the bearing races.
Improperly faced headtubes and BBs will result in a shorter life, if not
better function.

The two bearings on the BB should not come off easily. It sounds like

recommend a facing of the BB shell.

Peter,
thanks for responding. I did face the BB despite the protests from my
local bike shop mechanic...who i do trust. he had claimed that
cannondales "didn't need it", but i insisted.

Right and pigs fly. I see few(none) framesets from any factory that don't need
frame prep..even Cannondales.

yes and yes. prevents metal bonding over time, with moisture.Don't use loctite.
I just had to take a BB out of a Bianchi(AC-H) that used loctite, It only took
me an hour.

Hi Peter, Asking one more question of you, it's the continuance of
this procedure to then go next onto the crank installation.

Searching, I have also read to grease the axel shafts/spindles before
crank installation. And also after installed, and torqued "Do Not Play
with them"!

The question I have in particular related to Campy Chorus, or Record
Cranks-Axels, as I see these new Cranks come with an 8mm Allen Head
Bolt, and do not come with a Hex Bolt, and "Dust" Cover anymore.

Sure, I understand that an 8mm Hex Allen wrench will get you part of
the way with the Installation, but what about the tightening to proper
torque using a Torque Wrench?

Would I need to go out, and buy a 8mm Allen Socket that will fit on a
torque wrench so then to know I have proper torque. I don't feel like
guessing at this crank installation. Thanks, Mark

They cannot but most of the BB problems I've encountered are centered around a
non prepped BB shell. Few if any framesets these days are faced, chased,
prepped at all. If the BB has a cup that is against the BB shell, it needss to
be faced.

Dear Mark,

If you need 3/8" drive metric hex sockets, you might try
these--ten bucks, plus shipping, 4 ,5, 6, 7, 8, and 10mm:

Or a local hardware store or bearing supply shop might sell
you a single 8mm hex-bit socket.

Hi Carl, Thank you very much for the link!

I imagine many people probably make these (Sears-Craftsman, Stanley,
Snap-On, etc etc) Trying to walk into a store, and buy one of these
off the shelf might prove futile, so, your idea of buying online might
actually be a much easier process. I'll try to call around first, and
see what I can find.

I know GM uses these type of Sockets for Disc Brake Caliper Bolts, as
I have one, but if memory serves me correctly, these are 10mm, and not
8mm.

All I'll have to do then, is use a 3/8"-1/2 Adapter with the 8mm Allen
Socket, and I'll be able to snap this on to my 1/2" Drive Snap-On
Click Type Torque Wrench.

Maybe Park Tools needs to start carrying these, as going with Allen
Crank Bolts seems to be the Wave of the future? Thank you again Carl!

Oooops! Forgive me all, but I do see that Park Tool does make Hex
Allen Sockets. I imagine another good quality brand, such as Snap-On,
Craftsman, work work just as good in this case. Mark

I do what Campagnolo says to do, and have for 20 years, and that is install
onto the Campagnolo spiondle , dry, to torque. I have been doing this for years
and have not had any cranks fail, split, fall off, etc.

I use a beam type torque wrench with a 8mm allen end on it.
