Viscosity at SME Damper Fluid part no. FD2013

Post by B.M.F » 02 Jun 2009 18:01

Hi!

Does anyone know what viscosity it is on SME Damper Fluid with part no. FD2013 LV (low viscosity)?

SME Damper Fluid part no. FD200 have viscosity 100.000c.s.

SME should be able to tell you. Give them a call or send them an email.

I always used baby oil instead and/or trimmed the smallest paddle down to a point with the SME fluid. This worked well, giving just enough stability without slugging the free movement too much.....

The answer from SME Technical...

Post by windbag » 19 Nov 2010 14:56

Since I failed to pin this down properly anywhere on the internet, I followed the suggestion to contact SME Technical.

They have just replied, saying the viscosity of the oil in the the FD2013 LV vials is 60,000 cs.

The other cited part number (FD200) was the original full damper kit.
Since SME later supplied thinning fluid, the quoted original viscosity of 100,000 cs is consistent with this.

I'm using the FD-200 kit on my SME 3009 Improved arm. The fluid I'm using is 50,000cs. Here a picture of the bottle.

14264


Cartridge I'm using is an Audio Technica AT-440MLa. Using the middle paddle. Filled the trough so the fluid comes up half way on the side of the paddle in the playing position. Sounds the best at this level.

The arm comes alive when using the Fluid Damper. The bass & treble is so much more defined. Soundstage sounds fuller with every instrument taking it's place within.

I wouldn't use the arm without it!

Coming to this thread very late. My FD-200 (bought new in the early 80's) says the fluid is 200,000cs in the manual.

Because I've just brought my deck out of 20-year retirement (one of the best decisions I've made) I needed fresh damper fluid. Best source is R/C car diff oil. This is available in a whole range of viscosities from 10,000c/s to 1,000,000c/s. I bought 200,000 because that is what the manual says. In the UK that was £15 for 35cc - and the bath takes 2cc. So lots of spare, and if I ever want to change the viscosity, it is a cheap thing to do.

But from what you guys say, SME changed the spec downwards to 60,000c/s?

When I bought my FD-200 fluid kit it had an original SME tube of fluid. Yes it's 200,000 cs weight. I do like the SME 200,000 fluid better than the 50,000 I was using.

The instructions says to let the fluid completely empty out into the trough. Once it's all empty you will have to remove some of it. I used a pin and took out very little each trial. Once you remove some play back the song over again to hear any difference. When you get the correct amount removed you will notice. Midrange comes to life, bass is deeper, soundstage is wider, highs are more light and airy.

With the arm in the playing position the dampening fluid is halfway up the wide part of the sides of the paddle. Make sure the bottom of the paddle is parallel to the bottom of the trough.

I'm using an Audio Technica AT-440MLa cartridge with the middle paddle (20-30 compliance). Arm is the 3009 II Improved Non-removable headshell with a 3 gram headshell weight. Sounds really good!

Here is a picture of the FD-200 kit installed on my arm, in the gallery here.

SME has the fluid at 60,000 now because the new arms, IV & V series, it only dampens in the horizontal axis plane only, not in both vertical & horizontal like the 3009 arms do.

Having read a lot of positive reviews I have recently purchased a complete FD-200 kit off eBay for use with my 3009 Series II Improved. Following the recommendations I have also purchased a 60ml bottle of 100,000 cst silicone oil. However, this stuff is really thick & viscous, like a mix of treacle and petroleum jelly!

Can this be right? Have I got the wrong stuff?

Some members suggest using baby oil or sewing machine oil which would obviously be a lot thinner and much less viscous. I am worried that if I put this viscous stuff in the fluid trough I will never get it out as it is so thick & sticky.

Should I try and get the 50,000 cst silicone oil instead? Would this be the right stuff or would this this too thick as well?

Any help would be much appreciated :)

I suggest you get the original SME fluid. Yes, it's really thick. The original SME fluid works the best.

Thank you VITB, much appreciated. Earlier posts suggest using R/C car diff oil as it is significantly cheaper. I bought the 60ml bottle for £4.65 here in the UK. Of course, cheap is only cheap if it works NOT if it ruins my FD-200! I have nothing to reference the viscosity of the fluid to hence the post. I was surprised at how thick & sticky 100,000 cst is and wondered how it would work. Do you mean "really thick" like treacle?

How thick is the 200,000 cst Craig? Could you describe it for me?

A tip for removing the really viscuous fluid. . .use a cotton swab (Q-Tip here in the states). Works fairly well, but you'll need several of them. Each one is good for a few dunks, wiping them off on a paper towel.

Hello!

It's time to revive this old thread again! :D

I bought myself a minty FD200 kit in a box.

The only thing that is missing is the fluid.

You say that you like best the original 200.000 cst fluid and that it is better than 50.000 cst fluid that you have used before...

Is it better only because of the higher viscosity?

It would be too difficult and expensive for me to order the original fluid.

Locally I can buy some 60.000 cst silicone fluid.

You are saying that you are getting the best results with medium sized paddle halfway immersed in 200.000 cst fluid...

Can I get the same result if I fully immerse the paddle in the 60.000 cst fluid?
...And if this is not enough, use the largest paddle?

Or there is some unique quality to the original SME fluid, other than just the higher viscosity?

Great advice guys! Just picked up
my first SME with this damping system.
Used the arm for a week without the
Dampening system in place and couldn’t
believe how much better it sounded over
my stock Oracle Prelude Arm. Yesterday I
installed the damping and filled the reservoir like the instructions called for.
What happened to my highs I thought.
Really took the life out of the overall sound.
After reading above posts I removed enough fluid so I could see 1/2 the paddle.
Wow what a difference, the highs are back
and sound stage is wide open like never
before. Just for interest I’m running a Grado
Reference Series 2 in a Series 3 SME on an
Oracle Alexandria table. This is being feed into Mcintosh gear and Harbeth speakers.
Thanks for the info guys. 😎
