Window parts are broken and need to be replaced
Hi there- thanks for posting!
We'll need to see some photos of the parts that you need replaced before we can identify the best replacement option for you. Thanks in advance!
Based on your description, it sounds like you need your pivot shoes. However I cannot see them in your photos. They are too obscured while they're still installed. You'd need to remove them in order for us to be sure what you have.
I can say that your pivot bar is similar in design to our 26-446. Whether this is really what you have, I cannot say. I can say that the 26-446 is commonly used with the 15-177 pivot shoe. That may be a place to start, but I still highly recommend removing your shoe from the window to confirm. This is just an educated guess, at best.
Our replacement parts are (for the most part) intended for any window that happens to use the same hardware. I've never encountered a window that we don't offer at least some hardware for. Get back to us with photos!
What exactly would you like a video for? We have a ton. If you wanted videos on how to remove pivot shoes in particular, I'll pop a fon this post for you to review.
The three videos I just posted would show you how to do that in detail. A Kohler window is no different to work on than any other brand of window.
