Like the title says. I've tried a 3 arm gear puller several different ways and no luck. What's the trick to pulling this pulley off? Every time I get it to grab as soon as I start to tighten the puller one of the 3 arms slips off. I've read on another board that the 3 arm puller works but I can't figure out how to get it to not slip off. Tricks? Or another option for removal?
