Remove/replace original Pella casement window

So I have original (40+ years old) Pella windows in my home, one has turned cloudy recently. I found a local glass shop to reglaze it but I had a much harder time getting it out than I expected, and I'm hoping to learn what I did wrong to make reinstallation easier. This is the frame the window came out of:

I thought I'd be able to remove the opening mecanism and simply "pivot" the window out, but I ended up unscrewing every piece of hardware from the wooden sash; the bottom piece was especially difficult.
Looking at the bottom left of the second photo, there's a set screw that keeps a sliding mechanism from coming all the way off. I'm considering removing that screw and sliding out the mecahnism so I can then attach that piece to the bottom of the sash. Then I'd hope I can slide the bottom back in and reinstall the set screw. That is, unless I get some better advice here....

You don't need to unscrew anything from the sash. You remove the 2 set screws that otherwise block the track. You remove the 2 large washer head screws from the guide arm, then slide the entire sash out. Or in your case, back in.

You will want to clean those tracks well with silicone spray. And be careful not to break the pivot shoes if they are plastic they will be brittle.

I’ll open another and take some photos and you can show me the set screws.

It's the screw in your last photo. There is one on top, one on bottom.

I guess it’s the “washer head screws” I have to figure out.

Open a window and look at the top.

You need to Zoom out and take a photo of the entire sill on a window you have not disassembled.

To remove the sash you crank the window all the way open 90 degrees. You remove the 3 screws on the operator hardware on the bottom left corner of the sash. The interior face of the sash, not the top or bottom. You remove the 2 set screws that block the track that we talked about earlier. One on top, one on bottom. And you remove the big washer head screws on the right control arm (there is one on top, one on bottom. Then crank the operator all the way back in. Then slide the sash out. As I said, a clean track will make life easier.

well, I tried to use this method to reinstall the sash but it was easier to just reverse the steps I used to remove it. I don't know if removal instructions are slightly different for original Pella Window Vintage range of 1967- 1993 but the plastic guide that slides in the track simply sits in the slide roller which makes it nearly impossible to stay in place while maneuvering the sash; far easier to remove/reattach the parts to the top/bottom of the sash, as difficult as that was.
