Not that good but you can use a hammer,if you dont want to mark up your crank put an old rag over where your going to hit.

Take out the bolt.

Pedal around in a parking lot, driveway, etc until you feel it loosen up (WARNING: Don't ride it hard, just pedal in a circle)

It should come right off after that.

I think that it's impossible without damaging your crank.But If you really want to remove it you can do it with a hammer.Frown

oh alright but you dont need a crank puller to put it back in do you?

Nope. That's what the bolt is for.

Hate to ask, but why do you need it off if you dont have a crank puller? You're clearly not well equipped as a home mechanic, and maybe should consider leaving some of the BB area as a secret undiscovered country.

Just because he doesn't own a crank puller you assume he is not skilled enough to take off a crank.? I don't own a crank puller and I have succesfully done almost everything that you would ever do on a bike.

A hammer and a new set of cranks. Just take it into a shop and pay to get it done, not worth your time.

A number of things made me assume he shouldnt be tinkering with stuff like cranks or BB's. Started with not having the correct tools for the job, then asking how to remove cranks.

its a valid question. its only held on by a single bolt so you'd think un-screw it, give it a wiggle and disco!

i have self-extracting bolts on one bike - nice!
on the other bike i use foot long lump of 4x2 and a hummer

Cranks stay on a BB spindle cause of friction. Square taper, ISIS, Octalink, Howizter, X-type, etc... They all work on friction.

It's not as easy as wiggling them off, there's a little more to it than that.
