how rare is a 3.27 LSD axle
« on: August 14, 2018, 20:24:49 »
How rare is a LSD from a 4.5 with 3.27 gearing? I can't find any info on that or how many LSD were installed on 113's.

It was a fairly expensive extra option, and also the buyer would have to foresee a need for it (steep slopes, tow hitch, winter driving etc). So, I would estimate the number of customers who chose that SA to be low, say in the 3 % range.

When trying to check into this, I find conflicting information in different publications, including the spec of my own car and contemporary test reports.
Was there a different ratio for the stock rear in the 280 for different markets?

Sorry for the nonsense I replied before.
Should have better read Dan's request before.
LSD (which is the official abbreviation for lysergic acid diethylamine)
or ... limited-slip-differential (guess that's what you mean)
was only available for the 250 and 280ies, but not for the 230ies.

Don't know the numbers they sold.
I guess because it is all on papers when they "recoreded" that back than in the 60ies and 70ies at Daimler,
there is no computer-editable table (Excel) where you can easily extract that kind of info.
Basically (... I am afraid ...) you have to "count" this by reading all the datacards available ....

I asked this question because I'm going to have one available shortly. I'm trying to decide wether I should keep it or not. I'm starting to restore my 3.5 coupe which has a 3.69 axle but I'm also thinking I should keep it original so I may not keep the LSD axle.

Sure it is on the datacard. Where else?
Option code 256 in the field "wenig gewünscht" (= little ordered).
Why don't you look this up yourself in our Wiki?
https://www.sl113.org/wiki/DataCard/OptionCodes



Yes, Mike....
This was (still is) mentioned on the datacards. It's option code 256.
As this is/was one of the not-so-common = rare(r) option codes it is located in the field "Wenig gewünscht" (little, rarely ordered).
You can also review this here in our Wiki.

IMHO ...
a LSD rear axle does not make much sense for a Pagoda, at least for today's use.
We hardly use our cars on gravel roads/mud roads anymore.
The LSD is noisier, needs a very special oil (more expensive and rare) and is harder to overhaul - if you had that option.

Nevertheless, a 3.27 with LSD is rare, surely.
Sort of a hen's teeth option.

I have one in my car and find that it makes no noise at all. I can hear it when I'm in a parking lot during low speed turns when it growls at me. I use a good synthetic oil with a LSD additive both of which are easy to find. Both axles ( standard and LSD ) use all of the same parts except for the main carrier which contains all of the friction discs.

I find that my car pulls better from a stop and has a lot of forward bite coming out of a corner. Overall, there's a clear performance improvement.

Considering the chassis geometry and weight distribution of the W113 with a very light rear end, the crappy "Pendelachse" and the relatively torquey engine, I would thing a LSD would be an asset. My car lifts the inside rear wheel in fast turns and a LSD could help prevent the wheel from slipping.

I installed one decades ago and found no difference. I don't drive the car in snow or when the roads are wet. And I don't drive fast or hard or corner quick because I am old and take it easy. We just had a Mercedes shop in town who had very many parts for the old cars at very reasonable prices and I liked the idea to replace the 4.08 axle because I thought the car would be more civilized at our highway speeds between 60 to 75 MPH. I was right, it made a better car together with the 09 high lift cam. We have hills here and the performance is just right. Snoqualmie pass reaches 3000 feet in a very few miles, has a 3- lane road and 70MPH speed limit. Many cars have to take it easy and I do the left lane all-the-way. Only downside is the speedometer. I have to correct the reading by 1/4: 60MPH indicated is 75 but the State Patrol tolerates that in a 70MPH zone.
