Yes, if you take off the tabs and pull the SCD tray out all the way you can get it to mesh up with the gears again after the repair is complete. Don't try to twist or pull anything off, everything in that system normally comes apart pretty easily if you're careful when unscrewing and disassembling it.

My best advice would be to get a pen light and inspect as much as you can to find where to disconnect things, the whole system is a cool when it works but a pain when it doesn't.
