I’m having the “unplayable disc” problem caused by a dirty Hitachi spindle. I having a hard time removing the center spindle and been unsuccessful in finding instructions. I would appreciate any help.
Same here. I'm certain my problem is the spindle. Everything works just fine up until the point when I put a disc in. It makes an effort to start spinning but can only manage a small jerk. I can barely spin the spindle manually. I just need to figure out how exactly to remove it so that I can clean/lube it.

Move the laser assembly back a little bit so you have room to remove the motor once it's loose. You can spin the spiral looking shaft with your finger to move the sled and laser back some.
On the bottom of the motor is a plate with 3 screws in it, mark the 2 outside ones so you know where they sit since there are for the disc tilt/height adjustment you want them back to as close to the spot they started from as possible. After marking them tighten them and remember how many turns it takes to get it back to the marked posistion, this is pretty important or you may spen an hour or so readjusting the thing to get it to read everything again. Once that's done, remove the 3 screws, the center one doesn't need any kind of marking on it, and remember which outside screw went where. There are also 2 springs that are under the plate where the outside screws are, leave the drive upside down so you don't loose these.
After thse 3 screws are removed the motor, plate and flex cable will all come out as one piece. The top part of the motor with the Spindle and magnet just pull right off the motor with very little force and you can get to everything to clean and relube it.

What kind of head are on the three screws? They look like they may be TORX. I don't have a TORX smaller than a size 10 so I can't be certain it's a TORX and the size. Can someone confrim the three screws are TORX and what size I need to buy.
Thanks in advance for the great assistance.

However, like many, I had to tweak the POT to get all my media to load. Just a theory .... but I would expect the need to tweak the POT (increase laser power) if the potential data rate of the DVD drive has increased due to the spindle now spinning freely. I suspect I originally never had to tweak the pot because the spindle was slugging thru gunk ... slower revolutions ... lesser data rate ... therefore the laser needed less power.
Thanks everyone ... I'm happy again.

The POT tweak is done on most drives that have a dirty (should always try a good cleaning first), weak or failing laser, some just don't like burned media period. Disc speed doesn't have too much part in that, and the motor spun freely when it was new and it most likely had no problems then.
