Default Rega Planar 3 question about oil

Hi, I am new to the forum and couldn't find an answer to my question in a search.
I have a Rega planar 3 with a few years under its belt, as I know of no dealers that are nearby (I moved countries a couple of years ago) I would like to clean out the bearing and re-oil it.
I know what to do as I have already seen how the bearing comes apart (not mine) and how it is oiled, my question is;

What kind of oil should I use? and where can I get it?


Thanks

Chris

P.S. I am very practical and skilled....

The simple answer is as long as its full of oil who cares ?

My practical experience is that it makes no difference at all
as far as I can tell, the bearing being full being far more
important than any viscousity differences. The lighter
compound oils (3 in 1 for example) tend to dry out over
time and become more viscous anyway.

There is a school of thought that says light oils are the best
to reduce drag down to the area of record induced drag,
minimising motor vibration.
Its certainly true a synchronous motor will draw more power
to maintain speed against a higher drag load.
Balanced against this is the school of thought that says
thicker oils make the bearing more solid and improves 'integrity'.

Like I said I've been unable to tell, using any oil that
runs in any reasonable sense at room temperature.

If you want a thin oil then your best bet is 'sewing machine' oil.

thicker - household 3 in 1

thicker still - the various grades of car engine oil.

thicker still - car gearbox oil.

thicker still - motorbike fork oil.

I'd suggest oiling the motor as best you can will make the
largest difference (given the bearing is full) - you seem to
be saying that this shouldn't be a problem.

Sorry, but I beg to differ.

The kind of oil makes for an audible difference and not a small one either.

The less friction, the better.

Cheers,

Turntable oil bearing
Just sold my Logic DM 101 turntable to a gentlement in Japan.It was impossible to save original oil for shipping.I know there is many vinyl guru on Audiogon...is it possible to hear difference using different oil...what is the best to use.

I use Singer sewing machine oil in my roxan zerxes and never had a problem....anyone else doing similar? Remember, I'm not advising anyone else to do this, simply saying it's okay in the roxan....cheers, Bluenose

"It is essential to keep the bearing assembly fully flooded with clean oil at all times. A high-quality, clear and non-viscous oil is optimum. ... Don't use thick, viscous or exotic oils as these might attack the bearing bush linings. Sewing machine oil is a recommended lubricant, obtainable widely throughout the world."

There are many in the industry that recommend Mobil One synthetic for this purpose. It is what I use on my turntables air bearing between the surfaces that (nearly) meet.

A synthetic will not congeal, change viscosity or diminish its lubrication properties over long periods of time, even when unattended for years.

The version to use is 5W-30W. At room and bearing operation temperatures the viscosity will not be much different than sewing machine oil but has the additional properties that a synthetic provides.

The suggestions above are all good. To offer another option, you might consider getting a bottle of turntable bearing oil from VPI. I use the oil they supply for the bearings in their best turntables, and you can order it directly from VPI.

I have been refurbishing an old Thorens TD165 and decided to stick with Singer "sewing machine" oil as a safe bet (not their cheaper all purpose machine oil). Some of the synthetic oils contain Teflon and/or other materials, which has been said can break down and change into an abrasive with time (this is just heresay from the web, mind you). They sometimes contain other preservatives, which might be iffy depending on what material(s) the oil comes comes into contact with, like the TT belt and spindles. As far as I know the Singer oil has no negatives as long as you are not using it in a "grease" bearing and in this case it is not thick enough. Better yet is to use whatever oil the manufacturer recommends for your bearing as it was designed with this particular oil (and the weight of it) in mind, I would hope. I am not saying that all synthetic oils are bad, just that caution is advised in selecting the right one (don't just use anything).

Another synthetic I think worth investigating is Redline. They offer the usual weights 5w30, 10w30, etc. However, they also offer gear/bearing oil in various weights which is said to be safe with rubber. This oil is the MTL, MT90 and 75/90NS. They are sulfur free also. The MTL is about the same viscosity as 10w30, the MT90 about a 10w40. They have all the low friction properties of synthetics in fact I prefer the shifting in my car with the Redline after trying Mobil 1, Valvoline and others. I don't know if there is sulfur in motor oil. There is in gear oil. Jeff

Transmission oil with Dextron seem fine in my Thorens TD 125 MKII.

Well everything from sewing machine oil to gearbox oil,
obviously no bikers or we might have got the fork oil !

I'd be predisposed towards the sewing machine oil for the
Rega 3, due to the known fine tolerances of the bearing and
its a good bet for oiling the motor also.

The motor vibration argument is certainly more valid for the
Rega 3 than subchassis turntables, I believe Roksan always
advocated the minimum friction approach.

I have a rega p3, recently I accidentally pulled the bearing out and spilled some oil, so I asked my dealer what they used. He called rega and they said that they are actually using schedule 80 gear oil. So thats what I used. No magic to it.

End of story for you but there are better grade oils around...at a price.

Other than that a drop of PTFE suspended in oil can do miracles.

Mind you, that kind of colloidal solutions aren't easy to come by...

Cheers,

Cool Vegetable oil ..

Hey guys



I use light vegetable oil - better than mineral according to one PIO capacitor manufacture.

Does he spin his PIOs at 33RPM too?

Good point..

but 33.33333 is not exactly high rpm &
IMHO the requiremnt here is not the same as for high temp opertions where viscocity change is a problem. In the TT bearing application an oil should lubricate but also provide some mech damping without too much drag to help drown out residual noise.

Light voil, while not necessarily better than alternatives, may meet both requirements at vitually no cost - but a concern might be its long term performance like reaction with air but ... all oils should be replaced at reasonable intervals any way.
cheers
