Wormgear sticks

Postby Dildo_Schwaggins » Sat Nov 04, 2017 3:16 am

I have a PS2 slim 79001 that works flawlessly other than something I noticed a few days ago. After I turn it off and it is off for a while, next time I turn it on the worm gear is stuck. I have tested this by trying to move the laser on the rails (with my hand) after it has been off for a day or so. It makes kind of a crunch skipping feeling and then the gear loosens up and then the ps2 works fine once booted up.

If I try to run a game without doing this, it will sometimes be jammed and make a telltale noise.

What I am thinking of doing, is to put some sewing oil or wd40 on the wormgear then quickly tip the PS2 backwards vertically to allow the oil to drain into the worm gear motor

Do you think this is a good or bad idea, thanks. Personally I don't think it will work but it's maybe worth trying

Oils a bad idea I'm afraid, it will get dust and fluff in it and make it even worse eventually.

I'd clean it up, removing all the old grease and re-grease it with Silicone Grease, I would aim for a plastics one, I have one used on RC cars and planes which is perfect for any console drive rail or mechanism.

This might not even fix it though, it may be something else like a weak motor.

Yeah I thought so thank you. today I used it... I moved the laser and it slipped (a big slip) and then worked fine. But then put in another disc and it did the grinding noise even tho the gear was not "jammed" so I am not even sure what is the problem.. I looked up a couple videos on youtube of "ps2 slim grinding noise" one guy thinks it is the switch on the laser another guy cannot figure it out, it is the exact same noise as those videos

I'd like to see a video of it too, it certainly wouldn't harm.

In the mean time track down a spare if you don't have one already, you can get it 'console only' + if it's the same model you have spares.

I have a whole new deck, but don't want to put it in if it can be made working. This laser in there atm works really well and really fast. Today I tried a bunch of PS1 games and they all worked perfect without any grinding noise so I suppose it must be a laser related dvd malfunction?

this is the video it is exactly the same problem.

Thanks a lot

Possibility 1 : From that video and that sound looks to me your problem is not in laser , but in that side motor slider ( see picture 1 , it is not ps2 slim , but it is only convenient picture i find ) .
See where that blue arrow shows :

Well that slider on Picture 2 ( slim PS2 ) is loose , so it skips when laser goes up and down , that cause that sound . You MAY fix it if you tighten that lone screw that holds it , although that screw/screw layout is very sensitive and it wont withstand much screwing .
Otherwise , you will need replacement .

Possibility 2 : Your CD reader is loose/weak/dying and it needs pot-tweak .

EDIT :

Some of comments on that video are suggesting solutions to , for example :

The teeth under the arm that the worm gear moves, is worn. you need to bend it a little downwards.

Thanks, but the arm is seated perfectly and not worn, and it is screwed down tight. I added some more lube to the laser rails and a tiny bit to the wormgear, will see if that helps...
so the sound might be the slipping of the arm, and not the wormgear stuck? sure seems like it is the wormgear making the noise. Just like in the video, the wormgear is not turning much
