Line up the new crank with the old holes. The erstwhile screw holes are oft stripped. If and so, stick a toothpick or two in them as filler and drive the screws. Then reattach the crank arm and casement cover.

If your window crank handle just spins when it's turned, or information technology can't pull in the sash far enough to appoint the lock, chances are the gears are stripped and it's time for a new crank mechanism. Replacing the crank machinery is simple. But finding a new crank may take some time. You can mail your onetime creepo to some replacement hardware specialists and you'll get back a match (Photograph i). The cranks can exist expensive, but they may exist a bargain if the overall condition of the window is still good.

Start by inspecting the old creepo operator and handle for wear. If the teeth are missing within the crank handle, but replace it (at dwelling house centers and full-service hardware stores). Merely if the operator has cleaved or worn parts (Photo 1), supersede the entire operator mechanism.

Your operator may vary slightly from the one nosotros testify. However, the replacement process is like. The beginning step is to disconnect the crank arm from the guide track. Have out the screen and creepo the window open until the plastic guide bushing aligns with the guide runway notch (Photo 2).

Next, look for trim mounting screws inside the screen track. Unscrew them to remove the casement cover and access the creepo innards (Photo 4). If there aren't any trim screws, the casement cover is probably nailed or stapled in place. Slide a stiff putty knife betwixt the window jamb and casement cover. Carefully pry upwards the casing and then you don't damage the woods parts.

Close the window and lock information technology until the new crank arrives. Compare the new operator with the old, making certain they match. Install the new crank as shown in Photo 5.
