Sega cd model 2 question

Post by NWA »

My sega cd model 2's spindle is weird.... It looks like the picture provided, but the black part around the spindle can spin freelyby itself. Is this normal? It also can be pressed down like a spring is under it

The black ring spins on mine, but not independently of the "peg" that fits through the center hole of a CD. There is some give to the spindle when I press down on it to absorb shocks, but if I recall correctly, there were rubber bumpers within that gave it that range of movement, not a spring.

I read that there were at least two models of the SEGA CD 2, so it's possible that you got a different model than mine. Or maybe yours was repaired by someone in the past who used a different part. I can't guarantee that all the parts of mine came from the same machine - I bought mine from a reseller that buys lots of old systems and repairs them. Sometimes parts get mixed and matched between machines.

Thanks for the info Warp. Here's a pic of mine with a screw driver pointed at the black piece, just to be more specific:

The black circle I'm pointing at spins freely, so the silver circle doesn't spin with it, does yours do this?

Interesting. Does that little black circle lift off? I wonder if someone set something on it and it just... stayed there. Or maybe it is indeed part of that particular spindle. Mine does not have that. Unrelated - I do notice that you're missing the shield that goes over the laser unit track, at least in that picture. I would be fairly surprised if the other SEGA CD 2 model came without one, so my guess is that someone opened yours up at some point... possibly replacing the spindle. Does your unit work properly?

I took off the sheild :D I twas rubbing up against the disc because someone who previously went under the hood (sega: This is a refurbished unit) placed it uneven. When I tried it at the store it didn't work it said no disc, but I cleaned the laser since then and someone whos spindle looks exactly like mine on youtube said it is perfectly normal :D so my problem is resolved and everything is working well now. *EDIT: Do you know if my scd would be an early or late production unit? It is manafactured august 1994

Mine was November 1994. But as I said before, the seller I bought it from buys up lots of old units and repairs and resells as many as he can. I have no idea if mine has all the original parts or not. When I received it, it was missing most of the screws that hold the unit shut, so he mailed me a set of screws in an envelope.

As for the shield... I wonder if you could do what I did for my Saturn. I sanded down the underside of the shield to drop it a millimeter or two to allow the disc to spin freely.

Oh, wait! On my SEGA CD 2 I had to raise the spindle to get discs to spin without rubbing against the shield! I forgot about that! It worked okay when I got it, but you could hear the disc scraping as it spun. So... I fixed it!

With the shield and drive casing removed, I chose a flat metal tool (I chose a small paint scraper) and placed the flat surface on top of the metal rod from the spindle assembly. I then placed my index and middle finger underneath the surface that the CD sits on, with the metal rod between the two fingers. I placed my thumb on top of the paint scraper. I then gently squeezed those two fingers towards my thumb, causing the surface to move up the rod. Once the top of the metal rod was even with the top of that support surface, I stopped. No more scraping. Easy-peasy!
