I have an LSD and "normal" diff in the shed....
Pictures taken, though there are some differences in the stamped and the cast in numbers. However the main part number 12243301800 remains the same.
1.. Casting marks on LSD Diff.
Note the sideways "S" above "15 BMW". The white painted "E" (Ersatz?) shows it is a BMW rebuilt unit?
2.. Casting marks on the original out of the bucket
3... Tried to highlight and show the markings on the LSD diff, sorry a bit of a mess, but basically
11 43 - 3.09 Ratio on the rear face?
A9 80 - No idea, unless it's a rebuid date?
E - For Ersatz (spelling) for part/rebuilt part
4... Numbers found on the original Diff these were the only ones I could find.
12 39 - 3.25 ratio I assume
14 - No idea
2 - Sideways, again no idea
Any use?
