rattling kh cranks; loose seat post bolts

Post by xtremeskier » Sun, 04 Jul 2004 07:18:37


heh, today is my first day owning this thing and those are the exact
same problems im having. Well actually, for the second problem, I had a
tool that was able to tighten those bolts when I held it at an angle,
but im sure your LBS can take care of that for you.

For the first problem tho, I think we need to take the cranks off, and
lather the hub with anti-seize. I had the same problem with the kh
cranks on my summit and the anti-seize worked, so im guessing its the
same for the kh24. I am however going to wait until someone confirms
this theory for me before i go ahead and put the anti-seize on.

Anyways, dont get too e***d over this cuz both problems are not real a
big deal. Your baby is gonna be alright!

Yea, it will tighten if you have the right tools.  As for the cranks,
use loctite on the screws, and anti sieze in the splines.  That's all.
Now go out and enjoy that KH24.:D

Funny that you mention the loose seatpost, because yesterday I was
having the same problem. Today I tightened up the nuts very very tight
(bad idea), and one of the bolts broke off halfway!

Recommendation: err on the side of undertightening the bolts holding the
seat to the seatpost since they are a real *** to replace. First you
have to take out a few staples on one side, then pull really *** the
foam and wiggle the broken bolt out. Then you have to go to the hardware
store and get a replacement bolt and nut, which they probably won't have
in quite as small a size. Finally you have to put the new bolt in place,
and staple the seat up with a staple gun, which is bothersome since it
is a hard angle to use staple guns in, and the staples aren't a common
size.

Humph!  I can see that I'm not needed here any longer.  Soon everyone
here is going to be praising the miracles of Loctite and anti-seize.

Fortunately, I am still needed here because the apprentices are not yet
ready.  Loctite is a brand name and needs to be capitalized.  The
generic term for it would be threadlocker.  And it's anti-seize not
anti-sieze.  You still have a long way to go in your studies young
grasshopper.

Tightening the nuts under the seat can be tricky especially if you have
a brake mount under the seat.  Sometimes a standard socket wrench will
fit in there, but you'll probably need a deep socket or an extension.
Other times you can fit an open ended wrench in there, but that's
terribly inconvenient.

I use a screwdriver with removable tips.  I've fitted a socket
attachment on it.  It will fit in the tight places where a standard
socket wrench won't.  Although I have not tried this tool on a KH that
has the brake mount welded on the seatpost.  I'll attach a pic of the
tool.

Oh, and Loctite on the nuts under the seat is a good thing.  That will
keep the nuts tight so you won't have to mess with them again.

To turn those nuts, I use a 10mm 1/4" drive flex socket and a short
extension on my ratchet.  The price is $7.49.

A 10mm nut driver will also work, but it's hard to get the nuts tight
enough.  With the ratchet, you can easily overtighten them if you try.

the cranks can be taken off and then you put red thread locker on all
the bolts and tighten them really good.  and the seatpost and saddle
problem cannot be fixed unless you want to spend money. what i did was
bent the right size wrench so it could reach down there, but still it
works horrible. and later on one of the front bolts will come loose, and
you will tighten it ant it will come loose again.

Is it bad if I put anti-seize on the crank screws? Should I take it off
and put threadlocker on instead?

It's no problem.  I use anti-seize on the pinch bolts of my DM cranks.

You just want something to lubricate the threads as you're tightening
them.  Threadlocker will act as a lubricant when it's wet.  Dry threads
bad.  Lubricated threads good.

Using anti-seize instead of threadlocker means that you'll have to check
the bolts occasionally to make sure they're still tight.
