Install the new crank

Line upwardly the new crank with the old holes. The former screw holes are oft stripped. If and then, stick a toothpick or ii in them every bit filler and bulldoze the screws. And 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 engage the lock, chances are the gears are stripped and it's time for a new crank mechanism. Replacing the creepo mechanism is elementary. But finding a new crank may take some fourth dimension. You can postal service your old crank to some replacement hardware specialists and yous'll get dorsum a match (Photograph 1). The cranks tin be expensive, but they may be a bargain if the overall condition of the window is still skillful.

Start by inspecting the erstwhile crank operator and handle for article of clothing. If the teeth are missing inside the crank handle, only supercede information technology (at abode centers and total-service hardware stores). Just if the operator has cleaved or worn parts (Photo 1), supplant the entire operator mechanism.

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

Next, look for trim mounting screws inside the screen track. Unscrew them to remove the casement embrace and access the crank innards (Photograph four). 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. Carefully pry up the casing then you don't harm the wood parts.

Close the window and lock it until the new crank arrives. Compare the new operator with the old, making sure they match. Install the new creepo equally shown in Photo v.
