Nope, you need to remove the bezel (plastic panel at the front of the tray of the PC drive and also the front plastic face plate. There is no tray swapping. You swap the whole drive.
In reading your question I kinda suspect that what you’re asking is how to remove the old drive out of the recorder, if so follow these steps:
To remove the drive out of the 5045;
First you need to remove the bezel (what covers the hole) from the 5045 by;
1- press eject and unplug, this leaves the tray open without it reacting to being pulled and pushed.
2- you’ll notice that the bezel is attached to an extention (1/4 " or .5 cm) which clips onto the front of the tray so pull the extension from the bottom while at the same time pushing the extension up to release it from the tray.
3- Plug back in and close tray, now you can remove the drive, four screws, 2 on each side.
4- You’ll most likely need to trim, with a very sharp craft knife, the clip points on the front of the tray of the new drive to accomodate the Liteon tray extension.
In my case I also had to add spacers between the extension and the bezel, for spacers I sliced up a stick pen, kept the springs and used longer thinned shafted screws on the extension, not too long as to prevent the extension from clipping back on the tray.
On the new drive, do the same thing, plug it in, open the tray, remove the bezel, close the tray, disconnect, and now remove the front platic face plate, once both the bezel and face plate removed, the drive and tray will fit a lot better.
