Hi Folks, I recently purchased some springs, pivot shoes and other items. Can you tell me how to remove the old shoes and install the new ones? Thanks Richard B.

We recommend using the Swisco 75-069 Jamb Spreaders. Another option would be to cut out some of the track to get the balance shoes in.
See this discussion about cutting a slot in the window track to remove the pivot lock shoe.
