1. if i had the tool would it be a reasonably straight forward job to
disassemble and repack the bearings?
2. where can one get the tool to remove the outside nut and adjust
the bearings?
Thanks for any info.
It's kind of a pain. Adjusting the nuts is fiddly, and it's hard to get the
locknut tight enough.
So as long as your bearings are adjusted properly (with a little preload, not
completely free-spinning), I'd leave it alone. Just pop the dust cap off and
flush with WD40 occasionally, then relube with a heavy oil. I use Phil Wood.
I've worn out one set of these (because the bearings were too loose), but it
took five years and tens of thousands of miles. Since then I've had no
problems, with two sets on two bikes, and tens of thousands of miles on one set.
You need a little preload because of axle flex -- like with a cup and cone BB,
only worse because the axle is smaller and flexes more. If you can spin your
pedal freely, the axle will eventually wear unevenly, just like an old BB axle
does.
