Laser/CD Unit Service

Post by DD-Indeed » January 19th, 2018, 5:37 am

I recorded this footage last night, where I did my own service operation for regular 9002-model console. I've done this to every one of my PS1's and they all worked just fine after this. One console didn't even work before I serviced it with these methods.

Disclaimer thou, I'm not recommending to do this on your console or anyone else's console, this is just showing my way of doing this basic service for the reader unit. I won't take any responsibility, if you try this and the console doesn't work after that.

That's an interesting take on servicing these drives!

In your experience, how well does the oil in the motors fix work over time?
I've tried this with WD-40 and it works great for the first hour. After a few days or so, the motors definitely get louder again and I think they might have actually degraded overall.
A really well working spindle motor doesn't make any kinds of rattling noises when spinning up to 2x mode.
The motor in your video is working okay, but I've "heard" even better :)

Small note:
A little too much grease on the rails and in my opinion, no grease at all on the cogwheels is better.
They just don't need it and over time, dust will settle in the grease.

Use white lithium grease. Not WD-40.

Shadow:
Into the motors? How much of it do you recommend?

I already use this on the rails and it seems to be a good long term solution, so yeah, I can imagine this would work.

Yea, never ever put WD-40 over there, especially to the motors, they die from it (been there, done that).

Spindle motors always tend to have some loose on them, when you pull the axle of the motor up and down a bit, but this was still in pretty good condition.

And I don't have lithium grease in my posession, but the mixture of those two substances I used has proven to be good solution as well, for me at least.

No, I mean put lithium grease on the motor gears. Inside the motor assembly itself use clock oil since it's extremely light.

Okay, I'll check out the light oil.
It'd be nice if the motors kept that performance for a while :)

I don't have lithium grease in my posession, but this combination of that sprayable vaseline and couple drops of sewing machine/universal oil has been working well too. And the oil itself is light, so it works as well. Since I don't need some special sort of lubricants for other things than this, it's not necessary for me to get those, as these do as well and does not cause any harm. But I understand your viewpoint. :)

Hi ...
This is a very wrong way to lubricate ...
Pouring oil into the engine will cause the collector's brushes to be damaged.
Separate the gear, with warm water - Dishwasher - With the help of a toothbrush,
With. Wash carefully
Provide normal sunscreen,
Fill the syringe and impregnate the rails and gears
Very little and carefully ..
For electic engine, use "Seat" light oil
Inject the light oil with the tip of the syringe needle into the engine's bushings.
With a small injection, rotate the shaft and move up and down to get absorbed.
The lens metal piece that runs on the rails has 2 small plastic pads that are eaten over time and should be replaced.
It is better to change the hands of the gears.
Since the snail's spinner has been eaten,
The lens is in the wrong place
