Sliding door fix up questions

I am helping my friend fix her sliding glass door
The center door is the only pieces of glass (there are 3 panels tot) that moves and one of the rollers popped out.
Ideally I would like to replace both rollers, use the existing frame and glass, but I cannot figure out how to get the second roller free.
That glass is in good shape no cracks or drafts (when fully assembled, right now its kind of taped to a wall).
My second plan was to replace the frame/rollers/possibly the track and re use the glass but I am struggling to find the right words. I have some pictures of the bottom of the door and the doo
Thank you for your help.



Hello,
I can't be sure but your rollers look like the ones used in Capitol patio doors such as the 81-016 and 81-017. Both roller housings are the same except for the wheel location, which can be changed depending on whether your wheel is in the lower or upper position. These rollers are held in place with a type of axle pin like the 81-203 and the 81-303.


You'll need to use a type of pin like the 21-026B and a hammer to drive out the pin holding the roller housing in place. Note that you will need a 10-24 X 2" Philips head screw, along with a washer behind the head to adjust the roller to the height you need. Take a look at these rollers, along with the related hardware videos shown on this page to help you through the process. Thanks for posting!
