BMX - How to remove cranks from FSA spindle?

Hi all,

I know very little to nothing about the world of BMX, but I have decided to use BMX cranks on my singlespeed commuter, because I like the BMX chainrings (they have character) and because I wanted a 1/8" wide steel chainring, and apparently they are only made for BMX.

So I went ahead and bougth a Euro BB (that's supposed to work with a BSA BB shell) and a FSA crankset. In the FSA package with the crankset there was a tool for installing the cranks onto the spindle, and I do get how this tool works. What I don't get is: how will I remove the cranks from the spindle? The interface between the cranks and the spindle looks like it is going to be extremely strong.

loosen and wiggle?

Is that really the way it's done? As I said, these FSA (uses 19mm spindle) cranks seem like they'd be stuck really hard on the spindle. Even stronger than on a square taper, and even there we use crankpullers to remove the cranks from the ST.

I forgot to mention: there are no screws to loosen on the cranks themselves. Only on the sides of the spindle.

I know my friend didnt use a remover to get his off. and on my mirracos i just wiggle em'.

Rubber mallet.

when you loosen the bolt that holds the arms on. loosen it half way off the thread then hit the bolt with a hammer. do the same til the crank is just about off, then give it a few taps with the mallet. then pull the spindle out. that might help.

Alright. Thanks!

the tool would serve the same purpose as that bolt, and just smash on that tool with a mallet without the collar the tool comes with. When installing the arm you would use the collar. If you were unfortunate as I was I used a block of 2x4 wood and a mallet on the arm.
