Hi Rory
Sorry for the name confusion thing
. My name is often mispronounced as Leah (
Lee-ah) but anyway, I think it's often just my colleagues winding me up more than anything! So apologies.
Hi daddyiojiggy - welcome to the thread. Wow, that must have been a mamouth read if you started from the beginning!
Both the 119.970 and 119.980 have the MB clutch 119 200 00 22 which is identical to mine - not surprising since my SL500 engine is a 119.972 I suppose...
Here's a post I made about refilling over on the SL forum
http://www.peachparts.com/shopforum/showthread.php?t=94977&highlight=viscous
I used Dow Cow Corning 200 Fluid but the recommended VFC fluid is Dow Corning 211. The 200 has identical viscous temperature characteristics but comparing data sheets the 211 may have better sheer strength and high temperature properties than 200.
Simply remove the pin and use a 5ml syringe, I pumped in around 30ml on my first refill and 40ml on my second - of course the vloume is debatable and so I simply kept filling until it started to significantly tighten.
One obvious thing I have learnt is that if you need to refill, then the clutch has a leak - and I know of no repair. The leak emanates from the centre bearing and over time gives the inside of your fan shroud an unwanted fine coat of silicone!
Hope this is of some use..
Lea
