Update JD/All
Right after your post, I again removed Case Cover, and with some further examination, seen where the Belt was, and that its purpose is to open, and close the Drawer.
I was able to also carefully, and sucessfully remove the Delta's FacePlate, and also the Silver Metal Top of the Sled to get better access to the Belt, and Pulleys.
I then did clean-treat the little belt with the Rubber Rejuvenator, and a Q-Tip, and got to carefully clean the rest of the internals of the Sled mechanisn with a soft Artist's Brush, and Canned Air, being also extremely careful NOT to touch the Laser Lens. Just gave that a little blast with the Canned Air, and that was all.
Cleaned all other disassembled parts, and also the contacts from the Faceplate to main Body with Pro-Gold, and re-assembled the entire unit without a hitch.
Trying it out again, out of the first 40 times actuating the Drawer, it retracted once on its own.
And ffter another second 40, or so times of operating the Drawer, it hasn't retracted once under it's "own mind", so operation does appear to be vastly better! :-)
A couple of days ago, it was retracting virtually every time I opened the Drawer, and was making CDs a real pain in the tookus to load, so I knew it was time something had to be done.
I certainly didn't wish to get any of my more valuable Mo-Fi CDs hung up in the Drawer not being properly placed in the Drawer, and possibly scratching-scraping them in the process.
The Belt itself looked to be basically in fine shape, and only seen just a little bit of Black Residue on the Q-Tip after treating. I would assume a Belt such as this can be gotten somewhere?, and that the Transport Mechanism is indeed not made by Cal Labs, and was made by somebody else (TEAC?, or ?) Thanks again! Mark
