KH24 Hub Length

If the axle is not exactly centered in the hub it's not big deal. It's
only an issue if it is so far off center that one of the cranks cannot
get completely tight (the retaining bolt will bottom out before the
crank is tight).

Steve Howard has a gallery that shows a disassembled KH hub. 'Dissected
KH Hub gallery' (http://gallery.unicyclist.com/KH_hub) That will show
you what's inside. If the axle is too far off center it can be pressed
in the hub. The axle is just press fit inside the hub body.

If you need to press the axle back in you can use a bar clamp or a big
C-clamp. See the thread 'How to press out Profile axle out of hub?'
(http://tinyurl.com/476at) for instructions on how to press the axle in
or out of the hub.

If you don't want to deal with pressing the axle back in you can just
put on an additional spacer on each side of the hub. Go to a hardware
store and find an appropriate size washer or bushing.

The axle can get pulled out of center if you really tighten the big
retaining bolt on one side of the hub while the other retaining bolt is
loose. The retaining bolts can move the axle inside of the hub body
just like a bar clamp or a big press. The proper procedure for
tightening the cranks on is to get the retaining bolt snug (but not
tight) on one side of the hub then get the retaining bolt snug (but not
tight) on the other side of the hub. After both sides are snug you can
start cranking on them to get both sides really tight. Otherwise you
can pull the axle off center.

beat it even with a wooden mallet!........only under my super-vision
though 😄

PS, put the crank bolts back in the threads (no crank arm) then
beat...so you dont get splinters of wod in there....a rubber mallet will
nullify (sp?) that problema.

Just do not use a metal hammer. You can literally mash the end of the
axle like a mushroom if you use a metal hammer.

Ok great, thanks. Just for clarification though, the retaining bolt is
the one that screws directly into the axle, yes?

Yes. The big bolt that screws directly into the axle is what I call the
retaining bolt. The smaller bolt on the crank is what I call the pinch
bolt because it pinches the crank tight on the axle.
