Putting this spring block into a stock non LSD diff is a short lived hack. With a clutch type diff this is the standard mode of operation for millions of diffs. It took me about 2 seconds to find a vid that shows exactly what I have been pitching. Marker 0:55 to 3:25 is what you want to view. https://www.youtube.com/watch?v=WeLm7wHvdxQ&vl=en 0:55 to 3:25 Understanding Limited Slip Differential Quote:

The clutch 0.020in shims have arrived. Not unexpectedly they are too thick. The reason for them being too thick is that I also ordered new spider gear washers. The new spider gear washers are steel, they are new and more than likely thicker and certainly don't squeeze as much as the plastic ones. As soon as they came in I realized my shims were probably going to be two thick. I happened to have some thinner clutch steel plates so I was able to simulate putting 0.015" shims in place of the 0.020" shims. The result was too low a drag torque. Its supposed to be 80 to 160 NM, I'm at ~ 60. So I have reordered more shims in 0.015" thick and I can make up any short fall by staking in leftover thicker (less worn) steel plates that I have from another differential.
Unfortunately these shims do take 2 to 3 weeks to get but I'm in no rush as I still need to find some axles.

I didn't read everything from the beginning so if someone already post this, please don't mind. I thought you guys might be interested.
I found new performance clutches just posted on eBay. I know the company, they produce high performance clutch discs for various types of diffs including Lambo, Ferrari, Mustang, BMW and so on. So I believe they are quite good. For Merc they offer following: 185mm diff: - regular - https://www.ebay.com/itm/263704385681 - Cosworth - https://www.ebay.com/itm/264177045026 210mm diff - https://www.ebay.com/itm/264197888116 C63 AMG - https://www.ebay.com/itm/263501168729 They even offer discounts for bulk purchases. |

Did some checking out on those clutch plates on E-bay. Needles to say I'm not impressed.
The set comes with 12 1.5mm thick clutch plates and 8 2mm steel plates. The idea is to use 2 1.5mm clutch plates in place of the single sided selective plate. I have already found that 1 1.9mm plate will fall into the groove between the broached spline and the back face of the side gear. It also eliminates the steel that goes against the carrier and puts the clutch plate directly to the machined cast iron surface of the carrier. The concept was based on samples sent in by a customer that they made a set for and received positive feedback. I'm of the opinion that the total amount of testing done on this is based on the feedback of one customers 2 or three burnouts. I will pass. I recently received my 0.15" shims but assembly of the diff is now on hold for a speedometer sensor installation I working on. Lots of late and milling machine chips going everywhere. I don't want to be assembling gear boxes while that's going on.

I'll have to read through this one again, it's been awhile. I have a 3.23 LSD going in my wagon I just bought, I know it works from a couple loops at the end of my street awhile back but yet to be seen how well. I will want it pretty tight for sure. Glad you are engineering a good solid rebuild for these!!

I read through again. So did you get the plates made or get a price? Also now that I see how they operate(haven't had a mb lsd apart) , even though the two fairly low mile 560sl parts cars I have wheels spin like a stock diff, you think they will lock up under load?

Yes even though you wheels spin like an open diff they will lock up under load. I am beginning to think that the preload MB put on them is there to make sure they are quiet when delivered new.

0.015" shims have been installed and seem to fit well. I think this will be a very reasonable refresh option. We will see when I get if going. Unfortunately I am now playing the shim game for the pinion and MB has discontinued all the intermediate sises which include the size I need. So that will motivate me to get my surface grinder back into action.
