Install the new crank

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

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

Start by inspecting the old crank operator and handle for wear. If the teeth are missing within the creepo handle, simply replace information technology (at dwelling centers and full-service hardware stores). But if the operator has cleaved or worn parts (Photo one), supervene upon the entire operator machinery.

Your operator may vary slightly from the i we show. Withal, the replacement procedure is similar. The first step is to disconnect the crank arm from the guide track. Take out the screen and crank the window open until the plastic guide bushing aligns with the guide track notch (Photo 2).

Adjacent, await for trim mounting screws inside the screen track. Unscrew them to remove the casement cover and access the crank innards (Photograph 4). If in that location aren't any trim screws, the casement cover is probably nailed or stapled in place. Slide a stiff putty knife between the window jamb and casement cover. Advisedly pry up the casing then you don't impairment the woods parts.

Close the window and lock information technology until the new crank arrives. Compare the new operator with the quondam, making sure they match. Install the new crank as shown in Photograph v.
