Casement windows differ from sliding sash windows so the casement windows pivot on a hinge-type mechanism on one side and tilt accessible. The window is opened and closed (and stored at the open or shut place) with a manual window crank. Over the years, the gears of the crank could become stripped, making opening and close the window hard. In this event, you can get rid of a manual window crank in only a couple of minutes with some basic hand tools.

Unlock the window lock on the face of the sash, then rotate the handle on the crank mechanism to start the window. If the crank handle spins the stem, slide off the handle of the stem and also inspect the flux of their stem. If the grooves appear to be in good shape, inspect the matching grooves in the handle to see if the issue with the window’s operation is merely a tighten crank handle.

Connect a pair of locking vise grip pliers into the stem and also rotate the stem to start the window when the stem is stripped. Continue rotating the stem until the end of the crank arm aligns with the top in the manual track connected to the casement window. Then push back on the crank arm to dislodge the arm from the manual track.

Loosen the screws at the trim cover that hides the entire body of the crank mechanism by means of a screwdriver. If no screws are visible, gently slide the conclusion of a flat pry bar between the window sill and the trim cover to loosen the end nails or staples holding the trim cover set up. Lift and remove the trim cap.

Remove the mounting screws holding the crank mechanism in place with a screwdriver, then lift the entire mechanism off of the window.

Loosen the screws that hold the manual track to the bottom of the casement window, and pull the track off of the window. Pull the casement window shut with your hand, and lock the window using the locking mechanism on the face of the window frame.
