First one looks the closest, but could well be wrong :lol:

The units all look the same, but agree that it's impossible to tell which one is the better match!

Have you actually established what the fault is or are you assuming it's the head?

I have mine de-installed ready to strip for those exact reasons!
Watching with interest

For those that want to try just a clean up of any cd/dvd, a quick guide.

First off, this is generally a 5 spanner task, not because you need the hulks muscles but because you need a watchmakers touch. Although it feels robust there are some very very delicate mechanisms around the lens you should simply not touch even by accident. As such, I recommend this is only done on a unit that is already to all intents and purposes already dead. Your call!

Never ever use silicon grease on these things, it's way too tacky and the tiny servo motor cannot track the dvd optical groove fast enough. Too much of any grease will do the same thing, as will grease where there shouldn't be any.

The grease they use always seems to be a light lithium grease (based only on my observation of it being white) and the best source I've found for that is at decent bike shops who do small pots for repacking bearings. The spray white lithium grease is bad - it seems really light but once the solvent has gone it sets hard.

Carefully clean everything using pure isopropyl alcohol and cotton buds to get the dirty grease off, then regrease with just a trace of new grease. Not enough to be able to see it building up anywhere but just enough to make sure the whole Archimedes screw is coated with a very thin layer. Make sure zero whisps of cotton from the buds remains.

Greasing the slide (the mechanism that stops the lens swivelling around the archimedies screw) is sometimes needed, sometimes not - some slides use a ptfe strip against the plastic rail and these should deffo not be greased, but otherwise take your cue from the existing setup and copy what was already there. Sadly some slides have built in obsolescence and just let plastic slide on plastic; once worn these are almost impossible to bring back from the dead.

It doesn't need saying, but never ever ever touch the lens - it's the size and weight of a half lentil and is held in place by hair-diameter phosphor bronze spring wires. Any contact at all will likely make it unrepairable. I have seen dvd cleaner disks flip the lens right out of the head, so using these really should be a last resort when cleaning the mechanism has failed.

Use the macro feature on your phone and photo everything around a mechanism before you disassemble; like me you will never find that 1mm diameter ball bearing if it lets fly, so make sure you know it's there to be caught ...

I have never managed to fix a DVD drive, I don't think I have the delicate patience required.

So those links are all good, particularly the opuradio one.
But my problem, is that the existing spindle that goes through the holes in one side, is moulded on each end, so I can't remove it and refit the new head.
In an ideal world, I'd like to be able to find one with the same spindle already fitted.

So if you undo that big cross-head screw just above and to the right of the archimedes screw mount, and take off that plastic clamp part ( :whistle: 1mm bearings! tiny springs! :whistle: ), does it not allow the threaded rod to be removed from the rest of the assembly? I'd be gob-smacked if it was supplied without the threaded rod if there was no way to replace it.

No, that's just plastic, sitting on top of the metal and doesn't surround the screw.

The round bearings are pressed int the metal, the screw thingy goes through both and the plastic on each end seems to be moulded onto the screw thingy.
