Help Needed: Off centered HUB

Done! Let's see if it stays fix.

Thank you guys for your help!

Hop on and away!

PS: How do I change the topic title to: "SOLVED" or something?

Here are some photos of the doing.

*I always waste a 0,02 euro coin in the doing. Because my crank remover
is too thin and goes all the way inside the hub center hole.*

*I used a Shimano remover thingy to hammer down the ball bearings.*

Nice work! My bearings popped out like that because I didn't have
spacers in between the bearings and cranks.

What are spacers, and where can I get them?

Now that I think of it. Wasting money might be a crime

There goes inflation! :x

If you pound on a bearing again, be sure to use piece of pipe or
something (I've used a deep socket) that has an opening larger than the
axle, but almost as small so the pounding force is to the bearing's
inner sleeve. From the picture it looks like that Shimano tool pounded
the soft sidewall of the bearing, could damage the bearing.

I expect things are fine, since the bearing was loose enought to slip
over, glad you fixed things. Good luck with that ride.

Yes, the picture may elude, but I checked before pounding and it was
pushing the inner part of the bearing.

That is very important, thank you.

a spacer is a sleeve that fits on the axle between the crank and the
bearing to keep the bearing in place. You can usually make them by
cutting down the end of a seatpost. Not sure how well it would work as
ISIS cranks are tapered and therefore will move on the axle more as they
wear.

Is there any problem with the bearing slipping or the wheel being off
center. My trials is like that but I never thought it was a big enough
deal to fix it. Should I try and fix it or will it be ok if I just leave
it alone.

I noticed a little off balance in my 29er. It makes sense physically
speaking eventhough it was only half a centimeter. But haven't tried it
yet after the fix, so I don't know if it is only psicological.

It was not hard at all to fix, but if you feel like it may do more
worse than good, and if as you say you don't notice anything strange,
maybe it's better to leave it like that. Ha, great advice hex

Cheers

Rui, in this case the problem was in your bearing apparently. It could
also have been in your wheel itself like you assumed initially. If the
wheel is not wobbling but it is biased towards one side, that is not
called "out of true" as one poster said. It is called that your wheel is
dished. There exists also a condition as in your thread title, which is
when the hub is off-centre. That would be that if you ride, you go up
and down because the hub is not in the centre of the rim in a sideways
view. All three conditions are corrected through spoke tensioning, but
the procedures are of course different (and you don't need to know now
because your problem is solved anyway).

Your crank extractor is not of the right type for an ISIS hub. There
are special ISIS crank extractors with a bigger 'foot'. But if you only
lose one 0.02 Euro coin every time you extract a crank, and there is no
other problem (like still damaging the inner thread, or being involved
in the criminal act of destroying money), an ISIS extractor won't pay
itself back for a l-o-o-o-o-o-ng time. And maybe you could even re-use
the bent coin...
