    the plastic gear at the end is split making it a little wider on the split half.

    as the drive spins it will get hung up at that revolution.
    i tried to loosen the bracket that holds the motor then it does not grip the gear good enough, too tight and it locks the drive shaft per the revolution.

    its time to replace it.

    anyone have a dead fz1 cd drive. i don't need a working laser.
    let me know I'll buy it from you .

    I would take it off, glue it, then cast a copy with resin.

    stopped at the local craft store last night to see what they had,

    they only had resin, nothing to cast with.

    I think i can find an original one for much cheap at this point.

    I did find some site that offers to remake any gear min order $65.

    if i knew there was a demand for these id have a bunch made.



    this guys used a diff gear and it worked for him.

    still hoping to find one from a donor 3do

    "as you can see the new gear's pattern is slightly different,
    but it doesnt really matter.. Only thing you might notice is bit more noise from the laser when it's moving."

    That bit of noise likely will be the early death of something else in the laser assembly. If you get a replacement gear make sure it is of the same diameter and tooth count and cut. It might "work" but it'll likely be off in alignment causing other parts to force themselves to compensate.

    Fixed! :)
    with a gear from a Sony CDU-8002 mechanism inside an AppleCD-150.
    A guy at a local pc store gave me some old cd roms from 1992-1997.

    the gear looked like the lower gear in the above pic.
    i removed the center part and cut that in half so i got 2 replacement gears out of it.
    I then used a small screw driver to gouge the hole in a few spots.
    now the shaft fits snug with no glue.

    The 3do is working great

    was about to have them reproduced, was not sure if i could make the return .....maybe at $10 a gear for the next couple of years.

    i got 2 gears for free, cost me $4 for white lithium grease.

    i did not go that far, but i think it would be cool to start making common replacement parts for systems .

    having just recieved a 3do with this problem, i think i will give casting a go. the materials arn't that expensive and i've asked a respected supplier to point me to the right ingredients. Will update when my supplies arrive.

    Or you could find the diameter and tooth count of the gear you need and then find a CD Rom drive that is the same (technical manuals maybe?). CD Rom drives are cheap and I'd be happy to crack open my CD rom drive stockpile and see if I have anything for it.

    Well, if you do decide to get some spares made, let me know, I'd definitely chip in to get a couple of these.

    EDIT: FWIW, I ended up tracking down a CR-563-B CD-ROM drive and swapped out the whole laser, gear and motor assembly, and my FZ-1 is working like a champ again. I also found a compatible motor at DigiKey, and a couple of places to get the gears made. Think there would be much interest in an FZ-1 repair kit?

    Wanted to bump this and report in that the parts from an Apple CD 300 Plus drive work as well. Its a Matsushita CR-503-C drive. Only thing I had to do was swap the motor to spin the discs with the one from the old drive.

    i never got around to casting as i picked up another "faulty" 3DO to swap out for the part. It would be good to make a list up of all drives that contain compatible parts though, and i think next time i'm in japan i will hit up all the local hard offs as every one i've every been to seems to have boxes and boxes full of old cd drives.

    Im imagining it would be at least any of the Panasonic/Matsushita drives made from like 93-95 at least. Like I said above the only incompatible piece from the CR-503 drive was the drive motor. Everything else including the laser worked perfectly.
