Do a search for details but it started with double row, replaced by single row 'small' and that got replaced by single row large, which your engine has.

Thank you, I was trying understand as much as possible and to confirm that my engine was replaced like for like with regards to the X51.

Before 2005 I haven't read about any examples of the larger bearing being used by P.

That bearing has lowest risk of all three versions used by Porsche in the m96 but it is not zero.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have a replacement engine (replaced in 2010) from porsche with the serial as m96/03SAT665. Anyone have any idea what the S is for? "AT" means re-manufactured and 5 indicates the engine is from 2005, but no clue as to the S
The coding between your engine type and the beginning of the serial number are remanufactured engine code
AT
and the X51 designation '
S
'. The next three digits of the serial number reflect the year of the engine.
66W is 1998
66X is 1999
66Y is 2000
661 through 665 is 2001 through 2005, respectively
your engine type is m96/03
"S" is X51 designation
"AT" designates remanufactured or Austauschmotor
665 designates 2005
Thank you, I was trying understand as much as possible and to confirm that my engine was replaced like for like with regards to the X51.
I have a 2004 anniv which came with the x51 pkg std.
Stephen, using 66X as an example, does that mean the rebuilt motor was manufactured in 1999, or that it is designed for a 1999 car?
Thanks for the help.
If it has 66X still in it, it means the original engine was built in 1999, regardless of whether it was re-built or not.

If I can ask one more follow on-question. . . Since StephenB's motor was built in 2005 and mine was built in 2005, do they have the IMS / RMS upgrades that the factory was using at the time of manufacturer? Specifically, in late 2005, new M96 motors had the last IMS design. Would my motor also have that?
Yes, they probably have the non-serviceable bearing (without complete teardown) if they were re-manned in 2005. Before 2005 I haven't read about any examples of the larger bearing being used by P.
The good thing is the new larger bearing is about as strong as the original dual row...
"revised, larger single-row IMS bearing,
identifiable by a larger 22mm nut in the center of the IMS hub flange
. This uses a very large 6305 single-row bearing with a
load rating similar to the dual row 6204 bearing
compared to the earlier single row 6204 bearing which has about 2/3rds the load rating of the 6305." From

Hi, my 03 996 C2 received a new Porsche long block in Sept,2013. Trying to figure out the IMS bearing used. Engine # m96/ 03a166569511 although the sales slip shows m96/05 . Confusing to say the least. Porsche charged this gut 28,900 for the LB engine.
Any help appreciated.
Bonjour � tous,
Je suis fran�ais et viens d'arriver sur le Forum et je suis sur le point d'acheter une 40 Jahre 911...
Son Num�ro de s�rie moteur: M96/03
S AT

75255
Il s'agit donc d'un moteur X51 de remplacement fabriqu� en 2005, je cherche � savoir si le roulement de l'IMS a �t� fiabilis� ou connaitre son diam�tre.
Est ce que quelqu'un peut m'aider?
Merci beaucoup
That engine will have a single row IMS bearing and of greater diameter than the hole in the engine case. You cannot replace it without splitting the engine case.
3 on all M96 versions that used an IMS bearing, not 3 on M96/03 alone.
Do a search for details but it started with double row, replaced by single row 'small' and that got replaced by single row large, which your engine has.
