Removing lower sash from the 15-087 coil housing pivot

A quick learner from Baltimore MD says:
How do I remove the lower sash from the 15-087 coil housing pivot?

Every video I watch makes the process of removing a window sash seem extremely easy. Simply release the top of the sash, lower until level, and pop one pivot bar from the shoe at a time. However, the 15-087 coil housing shoe fully encases the pivot bar. No matter what angle the sash is lowered to, the pivot bar never aligns with an opening in the shoe so that the sash will simply pop out. Maybe I am completely over looking some small detail but can someone help with this issue?

Sure, I'd be happy to help. Here's what I do: first, raise the sash about six inches and tilt it to a horizontal position. Then place your hands on each side of the sash and forcefully raise one side and lower the other side until one of the tilt bars comes out. For reference, watch the beginning of the video below where Mike does the same thing.
