Model 2 Sega CD Spindle not Spinning

[tigyi]

Hey, hey, Hey!

this will help you out.. sorry I didn't get to you sooner.

Once upon a time I found an abused Sega 2/Mega CD combo at a Goodwill (second hand store)
It had no power supply(s) and seemed to have some sort of liquid in it (motor oil or soda?)

for $2.50 I took it home, disassembled the Genesis portion and cleaned everything (won't get detailed so I can get to the point)

The Sega CD's Pop Top door was missing it's spring and there was some damage to the inside including the spindle and magnetic carrier support (piece on the lid that holds the CD to the spindle).

What I did, (and what you want to do) is find an old portable CD player. take the middle bit that the CD clips to and replace it with the one in the Sega Mega CD console. Also remove the magnetic carrier off the top of the lid (no longer needed). Think of how a Playstation 1 was designed... that is how we are changing this console. The shaft should barley protrude over the CD clip and the CD should spin freely on it. It might be trial and error to find a CD player with the right size spindle clip. A PlayStation 1 (original model) will fit too, but please don't destroy one of those just to get a Sega CD operational. Also, to be clear, the motor and shaft stays, only the CD spindle plate (or whatever you want to call it) gets exchanged and the magnetic support on the lid gets removed.

you shouldn't hear the CD spin up, the reason why you heard mechanical noise when you flipped the unit over was because the plastic magnetic carrier was scraping on the lid. It is only a 2x drive and shouldnt rev like 360's jet engine drive.

I hope that helps some people out there... I'm not 100% sure if it will help your unit though as it might have other goblins to deal with.

try operating the system partially apart, use your finger to trigger the door switch to make the CD spin-up...

there are so many troubleshooting techniques ... but I think we all give something a quick smack to determine if it is broken right?...

These images should help. I had access to the one I modified/fixed and a untouched original.




Oh, and I never mentioned... yes it worked perfectly after the repair!

Thank you

this may sound like a stupid question, but how the heck do you remove the spindle from the sega cd, and a mini psone (i have one that doesn't work) so i can put the psone spindle in the sega cd

Know that there are two pieces, the motor and shaft (one piece) and then the spindle plate (where the CD attaches). To remove that you have to pull, wedge, tug, twist it off.

PLEASE DO IT GENTLY!

Some CD units you can get a flat head screwdriver in-between the motor and plate then twist the screwdriver side-to-side to lift it off the shaft. it is held in place by friction... not glue.

I've never had the privilege of dissecting a Mini PSONE, so I cannot guarantee that spindle will fit the Sega CD's shaft. Also as a note - in some of the older model Playstation 1's they used a plate that was made out of a ceramic type material, where the plate looked black (or light gray). If you try and lift those with a screwdriver, get as close to the spindle before attempt to lift, any pressure on the plate and it will shatter. *note: use a screw driver or flat object that can comfortably slip under the plate, and try not to put any pressure on the plate; even if it isn't the ceramic type, you don't want to bend the plate or the CD will wobble.

If I can remember the sega CD's motor, shaft, spindle plate assembly; the screwdriver method will not apply due to how long the shaft is to the motor. With this you will have to be creative; do not bend the shaft or put pressure in the wrong place. Maybe use some pliers to grip the motor's shaft while you twist the spindle plate off. (don't grip the motor's shaft hard enough with the pliers to bend, the point is to keep it from spinning while you twist the plate, maybe put some rubber bits in between the pliers and the shaft?)

remove the PSOne's first, when successful, compare the Motor/spindle's shaft size to the one in the Sega CD. If they appear the same, proceed with the disassembly.

Wish you the best! also if you have the ability to post some pictures I can instantly tell you if the PSOne's spindle plate will work.

Final note, when you get the new plate on there, you will have to make height adjustments to tune the new plate the right distance from the laser. it is completely easy. it is just pushing, pulling or twisting it into place. The final results should have the CD Free spinning (like a millimeter) above the laser (not scraping anything). Use my pictures for reference, see how the plate is just above the plastic base.

Thank you, let me know if you require further assistance... let us know about your success too!

well....i shattered the psone spindle so now i have to find another spindle somewhere, i may go to the salvation army and see if they have an old portable cd player
