Ok u take of the cap at the end of the pedal, get a sockey and undo the nut, take out the washer then get plyier and undo the next nut, this is becuase a socket dont fit down this far. As your doing this the pedal will start to loosen up watch out for the bearings as they are loose and not caged, now u can take the platform off if u wish and regrease, but u dont really have to take the whole thing off, it just depends on what uare using to grease the predals, in ur case u would be using the little grease gun? u got with the pedals thenif so, u can get that in the tight places so thers no need to go so far to taking the platform off, just look out for the bearings becuase tey can go everywhere.
