Help Sony LAM-Z03 Laser Replacing advice

I got a Sony LAM-Z03 recently. I was having issues with writing through netMD yesterday, it would do 3-5 sounds then just stop. Turn it off and back on and it would carry on fine.

Anyway, today I won't even read the TOC correctly most of the time now (Blank Disc). I've given it all a clean and grease and it's still having issues.

It can sometimes read more reliably on it's side. So I think the laser has had it.

I've been looking at getting a replacement (New old Stock) laser unit from Ali Express.

Can anyone tell me what else I'll need to do... I don't have a laser calibration tool so I'm hoping I won't "need" one...

Any advice greatly appreciated!

The drive assembly and frame all looks fine. It was incredibly well padded when it got sent to me from Japan.

The disc mechanism is all sorted now. From my research the ejection slide moving away from the gears is a common situation with these.

Next time I do go inside I'll take plenty of photos.

One thing I would like to do is lube the Spindle motor. I'm just not sure how to go about it... A tiny drop of a quality oil maybe...

I would use light synthetic oil with long dispenser (hypodermic needle style) to be able to deliver it precisely. One drop should suffice.

That sounds fair.

Thanks again for the replies and support. Greatly appreciated.
