Rear Axle/Differential Number

[0049bri]

Can anyone out there help with the identification number
on my diff ?

I've got my Data card from Stuttgart and found on my 1970 280SL Pagoda
that i've matching #'s on engine and auto box, however, on the diff i find
the number: 110.357.0017, under this is SIUS 1 & BS 1.

I've checked with the codes section here but can't find the ref to Pagoda Diff #
As 110 on the diff and not 113 (Pagoda) does this mean that another diff is fitted at some time?
That would be a shame as my 280SL is so original.

Also can anyone tell me what on the data card is listed under #'s 41, 42, 44,46,49,50,51,52,59,64&66 ?
Bit of a tall order but would appreciate if anyone knows as i've values listed under these #'s which are: (6, 6, 0, 1,1, 3,5,4,5,1,9 respectively)

All the best, from a Brit in Germany.

The Datacard codes are explained in the Technical Manual.

A Datacard box number (44, for example) is the first part of an Option Code...the entry in that box completes the code....so Box 44 with a 6 means Option 446 which is decoded in the Tech Manual.

Thanks Richard M,

I've got the idea now! couldn't quite put it
together before your explanation.

Still can't quite suss out the differential markings
maybe i'm missing something again!. 

All the best, Brian the Brit.

Brian,
It would help to know which market your 1970 280SL it was made for.  You have auto transmission, therefore you most likely have a 4.08 :1 rear end (with transmission K4A-025) or a 3.69:1 (with transmission K4A-025).  Look at you rear axle plate for your ratio details, stamped on drivers side of differential.  Example, my 280SL Euro specs, with 4 speed manual transmission is stamped 027777 3,67.  This means I have a 3.69:1 rear end.  Please note that the 280SL data cards (which are differently formatted then the data cards for 230 & 250SLs) there is no differential number marked on them.  May I ask where you found your differential number stamped?
Thanks,
Bob

Hi Bob,

My 280SL was made for the USA market and the # 100.357.0017
                                                                          SIUS1 BS1
 is stamped on the actual diff housing.

I'll have another look to see if there's a plate with anything on it where
you suggest but last look i saw nothing apart from the aforementioned stamping.

All the best Brian the Brit.

the stamping should be at the drivers side (left side) of the diff. housing along the bottom.  There is a ridge at the bottom of housing for support of the casting.  you might have to rub off any dirt, or undercoating in that area of the housing.

PS. I did make a typo error in my last message, the correct stamp on mine is 027777 3,69.

Hi Bob , Real strange theses markings they don't seem to relate
to mine at all.

I have decided to register my car here in Burghausen even though i have a place
both in England and here, ( the stress is far less here and the same for the traffic!!)
therefore on Thursday i have the "TUV" ( an examination of the vehicle ) and registration
as an "Historic" this, along with the valuation at the same time by an expert here maybe
can throw some light on the diff #.

Thanks for your comments, and it's real good to "chat" worldwide with blokes who
 have the same interests.

All the best Brian the Brit.

Brian,
Good luck with thew TUV.  I lived in Heidelberg for some years, and still visit there often.  Wish I had my 280SL there, much more fun to drive there.  When I did live there in Heidelberg, I had a W107 1985 280SL.  What a great place to drive the SL.  I know you are excited to have your Pagoda there in Burghausen (I know the town).  Check with MB Classic Center, they might be able to help you with the mystery.  My contact there is Herr Grueninger Thorsten (thorsten.gruneninger@daimler.com), he might be able to help you.  Tell him that your American friend told you to contact him.
Let me know how you inspection goes.
Bob

Thanks Bob,

I'll let you know how the TUV etc goes.

It's being done at a classic garage here run by a great
bloke (Andy Zellbeck) really helpful and knowledgeable on all Classics.

All the best Brian.

Hi Bob,

Just to let you know as promised, the TUV was very successful with a bit
of a compliment.
You see over the last 3 weeks i've been under the 280 cleaning her underside,
and as i've a compressor i then spared on grey stone chip underbody protection
(not bitumen underseal) i then hand painted in the body colour blue 903H (terrible job, paint
running up the arms etc!!) but well worth it in the end as it looks like its just come
out the body shop. (you have to hand paint the top coat as it's not possible to hit
all the nooks and cranies with the spray gun).
The tyres need replacing as they are originals and slightly cracked also the speedo needs marking in KLM/HR
as they are MPH from USA.
It's quite difficult and expensive to find white wall tyres here so my search begins!!

Best regards, Brian.

Brian,
Good luck in you search for tires.  If you do not find whitewalls, I use Vredestein Sprint Classic 185 HR 14 90H.  I did lots or research on tires and found this tire to be closest to original specs Phoenix, but a radial not a non-tube tire.  Let me know your progress.
