For help "Right NOW!":

1. Say what you need help with in the subject line so people will read
it

2. Use the search function "Right NOW!" There have been many threads on
this. People already did the writing. Now you just need to do the
finding. Hints: You need a cotterless crank puller tool -- Your crank
type is cotterless.

That's a fair question. Usually cotterless cranks come loose when you
don't want them to, but hold like they're welded when you do.

But often you can get them to loosen up by riding around with the
nuts/bolts off. Hop a little with one foot in front, then a little with
the other foot in front. Or just idle for a few minutes with each foot
down. Eventually you should feel the crank moving around.

Don't overdo it; this will cause wear and tear to the parts.

Even if you do manage to get the cranks off without a crank puller you
will still have to deal with getting the bearings off without a bearing
puller. That's going to be the hard part. If the bearings are tight on
the hub (which the should be) you are not going to be able to slide them
off by hand. It requires something like 'this'
(http://www.unicycle.com/shopping/shopexd.asp?id=419) to pull the
bearings off a standard hub.
