Series 180 Coil Balance

A home owner from Calgary, Alberta, Canada says:
To whom it may concern, I have a broken coil and believe its a Series 180 and I do not know how to remove it from the track to service once I order parts. There is no notch cut out or access port like others described in the window frame.

These windows are purchased from Gienow windows in 2000-2001.

Can I just replace the spring once out? There was a 4 on the damaged one.

Any help would be greatly appreciated.

Hey, Dan. If the springs are the only things that are damaged then you could get away with replacing them alone. As for removing the pivot shoe housing, it will be tricky without a pre-existing cut out. Make sure to check at the top of the track, under the sash stop. Otherwise, you may need something like our 75-069 jamb spreaders. See the video below for more information.
