    I'm trying to take off a crank sprocket from a bike that looks like this:


    I've taken a crank off some 10-speed derailer bike and can't remember how I did, but this crank is different somehow, also, cant remember.. but its harder!

    I need to do this with basic tools (hammer, vise, hacksaw) so advise other options to pullers, I did get the other sprocket off without a puller. I think I just tapped around and it came off.

    Looks like a one piece- The slotted nut holding the sprocket on is reverse thread. Clamp the crank arm in a vise, sprocket/nut side up, then use a large, flat screwdriver and a hammer and tap (maybe a "firm" tap or 3 or 5) in the clockwise direction.

    in this case, lefty-tighty, righty-loosey.
