Laser/CD Unit Service

[DD-Indeed]

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.

[DD-Indeed]

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.

[rama3]

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

[DD-Indeed]

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

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

I have silicone grease and sewing machine oil as a mix, but to
better replicate what was done there, is white lithium grease safe enough
for lubricating the rails and gears as shown in the video? I've never heard
of sprayable vaseline, is why I'm asking, thanks! Oh, and pardon the sudden
bump, just not sure what the thicker substance was, and was wondering.

UPDATE: Upon doing some research, I found an opinion
On Reddit that does not recommend sprayable silicone
grease in an aerosol can, which I have, because they
can make the plastic brittle and crumble. I'm seeing
recommendations for mainly using white lithium grease,
and want to make sure that's the safest, correct way to go
with this stuff.

you can use silicone or lithium grease, molykote can be used on plastic and metal

[Administrator]

I believe Tamiya (the Japanese RC car company) makes molybdenum grease which isn't in an aerosol can. That's perfect to use on the gears and rails.

[MegaMan1991]

Appreciate all the responses folks! I've got some white lithium grease, which is what I'm using from now on!

[MegaMan1991]

Hate to bother you folks again, but the plastic gears don't need any lubrication if I'm correct? Used white lithium only on the sled, the metal gear and the metal motor gear next to it, but another one is pretty much all plastic, except for the sleds of course.

[Administrator]

The sled (on both sides) should have grease, and all the plastic gears should have a little grease on them too.

[MegaMan1991]

I feel comfortable using white lithium on the sleds, but the plastic gears not sure what to use. Don't want to gunk up anything there. Do I use silicone aerosol on the plastic gears on a cotton swab, or sewing machine oil? Sorry, sorta new to this thanks.

[Administrator]

Use lithium grease on the plastic gears. Not oil. You only use oil inside the spindle motor.

Ah! Makes sense, ruined my other laser mech with silicone aerosol, which is extremely oil-like, and wouldn't want that
to happen with the replacement I just got. Used actual white lithium grease on the gears as well, and its running a lot quieter. Sounds much more like a good laser than a printer. White lithium is such a lifesaver; used that on the three rods inside of my PS3 laser mech rods, including the golden one, and runs like day 1. So, I noticed that supposed "silicon grease" that came from an aerosol can has so far only ruined what I used it on. Don't know if they sell it in tubes with a thick-paste texture, but I advise highly against any of the canned ones, as they're just too oily. Just my opinion and experience with it really. I also want to note that I used several paintbrushes to distribute the lithium grease normally, and in hard-to-reach areas, and absolutely did the job here!

For my experience... I use Silicon Oil (F72) for motor sled/motor spindle), and lithium grease for the gears. Never an issue.
