    I have to take off this pully to replace the timing belt. Is is
    regular threaded (counter clockwise to loosen)?
    or reverse threaded (clockwise to loosen)?
    Thanks for you help!

    This bolt is right-hand threaded, so yes, it loosens by
    turning counterclockwise. It is, howevever, often
    notoriously tight. Some options for freeing it:

    Would you please give your model of Honda and miles on it in
    the future, for info purposes in case this discussion
    proceeds further?

    I’m new here and have gone thru the all the messages I can see for 96
    and 97 accords without seeing the "direction" for this huge bolt.
    Even the manual doesnt say, which makes me guess it’s a normal
    threaded bolt. But with the amount of force needed, I’d hate to start
    the wrong direction, and believe many of you have already done this.
    Thanks

    Yep, it's normal thread, that's why the huge torque. When you
    reinstall it, don't leave it too loose or it will undo itself.

    it's normal righty tighty. if you couldn't find it, it was because you
    were just looking just for accords - all honda motors are the same in
    this regard.

    be warned - these bolts get /real/ tight.

    #1 best solution is a high torque air impact fixed to a high volume air
    supply.

    #2 is use a 3/4" drive and a holding tool like you'll see at
    http://www.tegger.com/hondafaq/cranktool/index.html. i have a 3/4"
    breaker bar, 16" extension [gets you outside the wheel well],
    3/4"F>1/2"M adapter and a 17mm impact socket - bolts come right off with
    that!

    #3 is run the risk of injury, car damage and tool breakage with 1/2"
    drive tools and cheater bars.

  7. As the others say, it's normal thread and tight as the very devil. The links
    to TeGGeR's site will give you the whole run-down.

    I do want to mention that the crank turns CCW, unlike most engines. Don't
    turn it CW in trying to get the &$#! bolt loose and don't try the trick of
    putting the cheater bar on a jack stand and bumping the starter... the
    cheater bar will just whack the fender well.

    I found a 500 ft-lb impact with 90 psi right at the tool got mine loose
    after a bit of trying.
