Otherwise, remove the dustcap, if any. Many cranks use snap-in/pry-out dust caps, rather than threaded ones, or the dustcaps may be unscrewed with a five-millimeter Allen wrench or a wide-bladed screwdriver. (Don't use a small screwdriver, as you run the risk of damaging the slot--most dustcaps are soft aluminum or plastic.) If you don't have a large enough screwdriver, a cone wrench or a dime will often fit nicely. Some 1990-1996 Campagnolo dustcaps, usually with self-extracting crank bolts, unscrew clockwise, in which case, you may have to resort to using a gear puller on the precious Campagnolo cranks, or heating them with a torch (see below), because left-threaded crank pullers are rare! | Otherwise, remove the dustcap, if any.

Next, you remove the fixing bolt or nut that holds the crank to the spindle. Since the bolt or nut is recessed inside a cavity in the crank, you need a socket wrench to turn it. If a nut is used, it will be 14 millimeters. If a bolt is used, it will usually have a 15-millimeter head; Stronglight and Zeus used 16-millimeter bolts. | Next, you remove the fixing bolt or nut that holds the crank to the spindle.

Hold the crank to keep it from turning with the wrench. This is usually easy, as the bolt or nut isn't torqued very tight. | Hold the crank to keep it from turning with the wrench. This is usually easy, as the bolt or nut isn't torqued very tight. | ||
