Roller assembly replacement part needed.

Question

I have a 48"x79" sliding glass door from "General Aluminum Products" Charlotte, Michigan (or at least that is an identifying sticker on the inside of the casing.

They are single wheel assemblies that I cannot figure out how to remove. I was able to separate part of the frame to gain access from the side, but still cannot figure out how to remove.

Attached are some images.

I see you knocked off the side rail, but you need to knock off the bottom rail. The patio door roller assembly has a top screw holding the housing to the door frame. If you look at our 81-004, for example, you will see a top screw hole. That's what you have to unscrew to get it off.

When you do get the roller assembly out please compare dimensions to our 81-004 patio door roller. I actually think that might be what you have, but there's only one way to know for sure.
