If your window crank handle just spins when it's turned, or it can't pull in the sash far enough to engage the lock, chances are the gears are stripped and it'southward time for a new crank machinery. Replacing the crank mechanism is simple. But finding a new crank may take some fourth dimension. Y'all can mail your one-time crank to some replacement hardware specialists and you'll become dorsum a friction match (Photograph 1). The cranks can exist expensive, but they may be a bargain if the overall status of the window is however good.

Start by inspecting the old creepo operator and handle for wearable. If the teeth are missing inside the crank handle, simply supervene upon it (at home centers and full-service hardware stores). But if the operator has broken or worn parts (Photo one), replace the entire operator machinery.

Your operator may vary slightly from the one nosotros evidence. Notwithstanding, the replacement procedure is similar. The first footstep is to disconnect the creepo arm from the guide rail. Take out the screen and crank the window open until the plastic guide bushing aligns with the guide rail notch (Photo 2).

Next, wait for trim mounting screws inside the screen rails. Unscrew them to remove the casement cover and access the crank innards (Photo iv). If there aren't any trim screws, the casement cover is probably nailed or stapled in place. Slide a potent putty knife between the window jamb and casement embrace. Advisedly pry up the casing so you don't damage the wood parts.

Close the window and lock it until the new crank arrives. Compare the new operator with the onetime, making sure they friction match. Install the new crank as shown in Photograph five.
