The sash stops must be removed, a thin vertical strip of wood that is used to hold the sash. Also, remove any hardware that has been painted. The sash can be pulled back to reveal the balancing weight which is a large iron cylinder that is encased in a hidden cavity and anchored by a rope.

Reassemble the sash by inserting the upper sash first into its track, then the lower sash. Verify that the sash stoppers and the frame are aligned properly. If necessary, reattach any beads used for parting. Then, reconnect the sash chains or cords and then re-attach the sash pulley axles.
