Ok, try this, find a bolt that fits the threads of your BB, but has a head small enough for the washer to fit over it, screw this in to the bb, then fit the crank puller as normal but with the smallest cap fitted. that way it should pull the crank arm and washer off over the bolt without mashing the bb threads.
What Crank puller do you have??
