Has that crank bolt ever been removed before?
I gotta tell you...that mofo was on like nobody's business on my 98 LX. The factory torqued that baby WAY past the recommended 120 ft lbs.
I made my own tool from a plumbing fitting(thanks to Curley from the
www.hondasuv.com forum

. I ground down the hex fitting until it fit perfectly into the opening in the crank pulley. I then used a big pipe wrench to hold it in place.
I still had a helluva time getting that thing off but eventually DID come off. I torqued it to around 110 lbs when I put it back on.
Good Luck!
