Do not use WD-40!!!  Only use grease on your cranks.  The crankarms are probably pretty tight on your spindle even after removing the bolts.  Find something to tap the spindle out, a 6in ratchet extension works great.  Don't use a screwdriver because the sharp edge will tear up your spindle.  Place the extension against the spindle and tap it out with a hammer.  You will have to hit it hard so don't be scared.  Sometimes a few good hits gets it and others it could take quite a few minutes so be patient.
