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! |

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. |
