Editing 3DO FZ-10 Repair - Lubricate the Laser Sled

THIS IS A WORK IN PROGRESS

This is a tutorial which explains how to lubricate the two rails that the laser slides back and forth on. You may need to do this if your 3DO FZ-10 can't read discs and has a laser that won't move. You will need

* 2 Phillips-head screwdrivers - a big one to open the case and a small one to work on the disc drive

* A small pair of pliers to remove the cover over the CD drive

* A grease that is suitable for metal-on-metal contact. I used white lithium grease, but I've also heard that pure silicone grease works. You don't need very much.

==Step 1 - Remove the disc drive==

To work on the CD drive, you will need to remove it from the console. Follow [[Panasonic 3DO FZ-10 Teardown|this guide]] through step 6 to open the FZ-10 and remove the drive. Put the rest of the console aside and focus your attention on the drive.

Five cables extend from the CD drive: 3 ribbon cables and two wire pairs. Two of the ribbon cable are connected to the laser, and the other is connected to the spindle motor. The orange and brown wire pair controls the motor which controls the laser's position, and the blue and brown wire pair controls a switch which lets the drive know if the laser has reached the spindle.

==Step 2 - Remove the laser sled motor==

Use your small Phillips-head screwdriver to remove the two screws show in the picture. The laser motor, which is connected to the orange and brown wires, should now be lifted out easily. Be very gentle with the motor, because the connections between the wires and the motor are fragile; the first time I worked on this drive I broke off the brown wire, and while making this guide I broke off the orange wire. They're easy to resolder, but be careful not to short the wires with the metallic casing of the motor.

If you see any gunk on the plastic gear at the end of the motor, you should wipe it off.

==Step 3 - Remove the laser from the drive and lubricate the smooth rod==

The laser rests on two rails: one is completely smooth, and the other is connected to the laser motor and has a spiral pattern. To remove it, lift up the off-white plastic piece that the spiral rod passes through. Be careful though since the laser loosely rests on the smooth rod and is not connected to it, so the laser may slip and hit your worksurface if you're not careful.

Once you've done this, put the laser and spiral rod to the side. Go ahead and lubricate the smooth rod now. If you want, you can remove the screw holding the rod in place to gain full access, but in my opinion it is sufficient to lubricate the section of the rod that is accessible since that's what the laser comes in contact with. Either way, you should first wipe off the old lubrication with a paper towel. Then apply the new grease, but not too much.

==Step 4 - Lubricate the spiral rod==

To remove the spiral rod from the laser, just keep turning the plastic gear counter-clockwise until the rod is free. Cover it in grease and rub it into the spiral indentation. Then I recommend rubbing most of the grease off of the surface of the rod since you mostly want the lube to be in the grooves and not on the surface. To remove the excess lube from the grooves, screw the rod all the way into the laser and all the way back out again, and repeat that a few times. Then wipe off any excess.
