nope no press or even a dremel. i tried the vise and hammer way but i guess i wasnt hitting hard enough

i was pretty scared id bend the shaft or something of the sort. hammer + motor just doesnt mix well for me. and i was wondering.. if i didnt care about the pinion anymore, as long as i got it off and the motor in good shape, are there any other ways? i have only limited access to a very limited tools
