Hello,

It doesn't look like you have the S140 coil assembly but we'll need to see your pivot shoe and coil removed from the window to identify a potential replacement. Thank you!

A home owner from Caledonia MI says:
It appears the window in need is a double spring assembly. The photos attached will be of a single as its been years now that the double has been discarded. If you could provide the part number for both single and double would be helpful. Also, can you recommend the proper lubricant for the track. Thank you

Your pivot shoe resembles our 15-192, which uses the Series 170 and Series 171 coil springs. Also, see our 15-156 cover and 15-157 balance drum. You shouldn't need any lubricant right off the bat but we generally recommend silicone spray if you require it over time.
