Pocket Door Repair
 

Anybody know how to re-hang a pocket door that came off it's track without removing the frame

All of the ones I’ve repaired require removing the top casing and header trim on one side. Not difficult at all. Plus you’ll need to determine why it came off the track. Typically it’s because of the rollers.

The roller pulled out of the top of the door. I was able to screw it back in but cannot get the rollers in the the latches in the track

I have seen a couple of YouTube videos, as I recall you may need to lift the door slightly. Also, check that the rollers and hangers are in vertical alignment.

I've yet to repair one here where the casing and top trim doesn't have to come off. A little bit more work, but without seeing the OP's set-up, I don't know a workaround
