Doors and Windows - Slider won't lift & tilt?

I know you folks may be somewhat tired of discussing sliding doors, but all I found via a search as to removal was "lift and tilt" and either I'm missing something, or it doesn't appear that will work on the 25-30+ yr-old door in my fixer-upper; So, before I break anything, if you could assure me of what I am doing, I certainly would appreciate it.

I don't see a brand name, but it is heavy and I couldn't really budge it much by simply lifting (though, some of it could be caused by the decades of crud which is caked by the rollers). I did however, stick a big screwdriver under the edges and using that as a lever, I can get it to go up, but it doesn't get high enough to clear the track.

At either end, down by the rollers there are what, probably should be called a screw and a bolt, both with phillips heads. The screws are recessed in a hole and are obviously screwed into the roller assembly and the "bolt" is about an inch or so higher with it's large, rounded head completely covering whatever it is screwed into....

Any hints about getting this thing out and back-in after I have cleaned or replaced the rollers would be appreciated.

Thanks in Advance;

FYI) It appears the door was framed into place; There is stationary door and my walls are made of cement block, if this has any bearing on the response. Thanks...

Does the upper edge of the door have anything on it? Rollers, guide pieces? Something that may be removable from either end? I don't recall any that don't follow the lift and tilt rule.


The inside edge of the bottom track, is it removable?

Chris; You are faster than I am; I had actually popped back with the intention of deleting this thread because I came back to the project and actually jerked-up on the thing and the handle-end popped-out over the track. I may have to take-out the stationary to get it all the way out and because of the cement block, concrete patio, cat and three year-old; I'm probably going to wait until the wife gets home just in case it starts going one-way while I am going the other; But, I guess the decades of gunk was holding it down and when I decided to be less gentle with the thing and give it a good hard jerk, it popped right-out. Though, all the leveraging with the screwdriver may have also been a factor in working it loose.

Thanks for the response; I've got it covered and I guess this should be a lesson to us all; Trust the info divulged by the folks in the "Door" forum and when all else fails; Try, Try Again.

Thanks and Keep Passing Open Windows;

Amazing how sticky time and dirt can be.
