Starter clutch removal no special tools

hi all, i am working on a 1979 kz1300 and my starter clutch has suddenly permanently engaged with some nasty side effects including a screaming noise and powdered metal, luckily i noticed straight away and the damage is very limited to the starting clutch area at a guess. I am now trying to remove the clutch and replace/fix it. I have removed the 14mm bolt, but the clutch assembly is not moving off, I don't have the special puller tool and wondered if it was possible to remove the unit without damaging anything, without the special puller .. any ideas welcome
