Here it is, post #3. Getting the roller in and tight was not easy, I removed the inflatable mattress from the couch and the metal cover under the couch so I could work at it from inside, plus the metal cover in the ceiling of the outside bay so I could work on it from the bottom as well, very little room for hands and tools. My roller that fell of was rolling around in the lower cover which I had removed to see about some lube.
What makes it especially difficult is you cannot tighten the nut to the stud without holding the inner allen head which is nearly impossible to fit an allen wrench into once the roller is in position. I had to heat and custom bend the allen wrench several times throughout the job as I tightened all 4 rollers.
