Most of these pegs have large diameters on one side and a smaller diameter on the other side, so it is essential to remove the smaller-diameter ones first. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line with a knife, then tapping the mortised section loose using mallets.
Once the sash is freed and removed, you can take off the sash stop and gain access to the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inner workings.
