I've completely disassembled cordless drill/driver Black&Decker EGBL188 H1 10mm, except this chuck, as seen in the pictures.
I've tried pulling out the plastic piece: I've put the chuck facing up on a bench vice so that only plastic piece touched the vice. And then, I've tried hammering out the chuck leaving the plastic piece on the bench vice.
But I unfortunately I had little to no success, it doesn't seem like it moved at all. Maybe there is some 0.5mm free move to it. I don't want to hammer with my maximum strength, because I feel like it can damage the chuck.
Because of my lack of experience, I don't know how to succeed further disassembling the chuck. Does anybody has done it? Should I hammer with all strength?
