I have an older Sugino GP crank I am trying to remove. It's been feeling wonky for a while now and want to remove it and possibly do some maintenance on it. The farthest I have gotten is removing the crank arm bolts with a regular 14mm socket wrench. My other bikes have newer hollowtech/gxp cranks so I know I don't have the right tools to remove the crank/bb on this Sugino. From what I've gathered on the web is it might be a square taper, and that I will probably need this tool: http://www.parktool.com/product/univ...d-cranks-cwp-7
and probably do this to it: http://www.parktool.com/blog/repair-...e-spindle-type

here are some pics:




am I correct on these assumptions? any help would be appreciated.
