low spindle?

[robotype]

I just saved four cdrom2 units which had the middle gear crumbled; 3 of them work perfect while the last one has the weirdest problem... the spindle is too low! so the disc won't spin when you close the lid. this is the individual box cdrom2 version (black spindle). I put some tape to lift it about half mm and it works ok! I wonder how is this possible? anyone knows how to rise the spindle assembly? or is there a discussion about this?

This happened to me, when I took apart my SuperCDROM2 unit. The spindle unit had fallen (maybe 1 foot off the ground), and landed up-side down. It pushed it in. I didn't realize it until I had it all back together. I just took it back apart (recently) and used a small flat blade screw driver to apply pressure - upwards on it. But I did this at the base of the motor and plastic piece on the metal shaft. It took a lot of pressure, so I wasn't able to move it upwards in small enough increments. So instead, I slowly tapped it back down to where I thought it should be. System works fine now (plays CD-Rs like a champ).

thanks for the suggestion. Actually I already tried to go under the spindle with a screwdriver and use it as a lever to lift it up but it doesn't seem to move the slightest bit...it's stuck in that position. feels like applying more force would result in a crack somewhere so I don't want to do that. worst case I will use some adeshive rings on top of the spindle to rise the disc. anyway how it went so low is a mistery. I can only think of a kid pushing the cd downwards.

I use a pair of angled pliers to pry them up. The angle helps nicely for leverage.
