What is the proper way to re- grease a laserdisc player?

[dpm]

Thanks for taking the time to look at this post -

I recently bought some "precision oiler" from Radio Shack for the purpose
of re-greasing the table gears of my laserdisc player.
Since there are no directions on the package, can anyone give me
directions on the proper way to do this? Do I need to open the chassis, or
will a couple of drops to each side of the disc table do the trick?

You're doing it all wrong. Get a child's swiming pool. Fill with 10 gallons
of used motor oil and lower player into pool and let it soak for a full day.

Did you misinterpret my post? The product I bought was manufactured
specifically for this purpose. I don't think that I suggested that I
wanted to do anything bizarre to a laserdisc player.
I don’t know your sarcasm sort of indicated this.

Your idea that you might do something usefull by smearing grease on the
tray without pulling the cover was about as silly as my idea.

You have to pull the cover. Examine the gears while ejecting the tray and
loading a disc. Also examine how the laser assembly travels. Understand
that you probably bought the wrong lubricant for the job. Understand that
you will probably do more damage than good if you don't research what
lubricant(s) to use, where to use them, and more importantly where not to
get any lubricant. Also understand that the laser can damage your eyes if
you somehow look into the beam; also understand that it is invisible.

Do some google searches to get a clue. There's excellant materials at
repairfaq.org.

Gee,I had no idea my question was so stupid.

"Understand" that one of the applications listed on the back of the
package "laserdisc and DVD tray. Also, I asked if I should apply - not
smear ,the grease, (which is in a syringe by the way) to the sides of the
tray and not on top of the tray where the disc would be.

Thank you for the warning about the laser beam - I did not know that.

If it works, why fix it? Does the tray have difficulty moving in/out?

Just because something is easily accessable, doesn't mean it should be
fucked with.

Sounds like you probably use those "cleaning disks" too. Well, quit it! Just
because something is easy doesn't make it a good idea. Scraping dust (tiny
rocks) off a lens at high speed is a terrible idea. [/pre-emptive]

BTW: the sides aren't part of the mechanics. The tray has linear gears
underneath. Apply grease to the sides and all you'll do is make a mess.

Back to my question. Applying this product which is cased in a syringe and
states on the back of the package for use on DVD players and Laserdisc
players. Knowing this, and with your vast knowledge, could the grease be
applied to "the gears under the tray"? Might this carry the grease back
into the player and over the affected areas? I'm just asking.

BTW: Are laserdiscs the same as DVDs?I just don't know. Speaking of DVD
players, I've been trying to get my Pioneer DV-09 to playback DVDs since
2001, but it has never worked - not even once. Are DVDs supposed to be
played label down? or am I doing something wrong?

Only that they're both optically encoded discs; laserdiscs are analog
whereas DVDs are digital (like a CD).

The only players I know that want the label down are Pioneer Elite CD
players
(e.g., PD-65 (I have one)) with a massive turntable. The theory being
the
laser head faces downwards so dust and debris won't fall into/onto it
-- it
does work! :-)

I see you work at Radio Shack.

If it's not broke don't fix it. Extra grease collects more dust and gums up
quicker.

And note that some mechanisms are designed to work without grease!
Nylon gears on nylon racks may have no grease.

Why do you think it needs lubrication? Is there a problem? And, if the
grease that was there is dirty or gummed up, you need to remove the
old mess first.

The spindle motor is probably permanently lubricated and squirting oil
into it will just make a mess.

The tray loading mechanism may need the be relubed since parts of that
may be exposed during part of the open/close cycle.

And there may also be rubber belts involved which after many years need
replacement.

But I agree, if there is no problem, leave well enough alone.

With spindle motors I have had very negative experiences relubricating them.
If the brushes get contaminated with an oily product they loose their
hardness and wear out very quickly (just few discs) and the motor becomes
useless as the brushes are an integral, non-replaceble part of it.
In short: don't relubricate motors; replace them with new one if they pose
problems.
