M130983 280SE /SL

[Cubalibre]

Hello,
I found a W113 engine for sale: 130983 10028874. There is a sign (photo attached) "280 SE /SL". Could this engine be factory installed in a  Pagoda or was produced as a replacement / spare part?

Cubi,
As far as I know, this engine was used in both the 280SE and SL.
I used to have a very late 280SL with the same engine ID.
Regards
Chris

I think what you have is a replacement engine that was stamped at the dealership when installed.  The factory block stamp is smaller and more even.  However the number stamped is a 280SL Manual transmission.  The SE/SL cylinder head is OK for both.

Dug a little further.

The casting ID 280SE/SL is on the cylinder head and used on most all late 280 fuel injected engines M130. The small riveted plate is the "Austauschaggregat" plate which identifies the motor as an official Mercedes replacement unit.
The serial number 28874 seems to be too high for a W133 280SL.

Apologies Gents,
I only looked at the cylinder head casting numbers.

Cubalibre, there is quite a lot of info on engine numbers and head casting markings here: https://www.sl113.org/wiki/Engine/CylinderHead

The stamp on the block below the cylinder head looks to be uneven. Are these hand stamped? Here is what is stamped on mine.

Hello,

Thank you for your message.
Contact with the seller is rather difficult recently unfortunately. Time to give up I think.

Regards,
Mikolaj.

CJ: Yours is very likely a remanufactured block with the serial number hand-stamped to match the original. There are still the two holes for the riveted "Tauschaggregat" plate.

CJ,  Not uncommon to see the last few digits askew.  I am sure they didn’t stamp the final number until the engine passed testing. Here is my original stamping.

Mike, Be careful not to mislead people. Where did you get your facts on that one? Both of the 1970 SLs I've owned looked exactly like that with the two holes, they were both built in Aug of '69, and I believe them both to be original to the cars. My pads look just like Shvegel who states his is original to the car also. Here is a picture of one I no longer own. Also has the last few digits askew.

[CJHenderson]

Wonder if I can ascertain that this motor is original to the car. Would MBUSA carry those plates and have one stamped for the block?

[Iconic]

CJ, those plates are for replacement motors. You might not want one.
So far, from what I have seen, your stamp looks original to me and it might be the original engine .....
If your '70 is a very early one with a VIN somewhere near 11304412012015?? or 012025??? then it might be original to your car.
Do you mind telling us your VIN?
Mine is 11304412012287 with original engine 130-983-12-00748.
Good luck. Discovering things like this is one of the things that makes this so fun.

PS: After closely looking at the picture of your engine number, Shevel's number, and pictures of the two I've owned, I would say, IMHO, that the last 5 digits were stamped by hand and the ones before that are very aligned, so stamped by hand more carefully, or with a tool of some sort. What do you think?

[MikeSimon]

I am sorry for the "misleading statement". it looks like the "rivet holes" are on all engines. I checked mine, and they are on there also.

[Cees Klumper]

This question, as to whether those little 'plate holes' are on all of our engines, has been bugging me as I want to run out to the garage to check my 12 or so engines - but they are in France and I am in California.

But from memory I am not so convinced that they are on all engine blocks, so am curious as to others' inputs.

[Iconic]

LOL. Very funny. I can't wait to hear what you have to say about your 12 blocks.
Please remember, the cars we have been talking about are all early 1970 280 SLs.
I'm glad we got you interested Cees, will someone be looking for you in France?   
Take care,
Mark

Mercedes-Benz published a "Service Information" in November 1968 and stated; "The well-known plate with the stamped-in model and series designation, code and serial numbers is no longer being used. Instead, on all passenger car models of present production series the engine number is stamped directly into the cylinder block in the same location where the previous engine number plate use to be."

[MikeSimon]

My engine is original to my LATE 1971 SL and it has the holes. Engine serial number is 15405. Automatic.
