Crankshaft codes

Post by Hurtzberg »

Hello,

One of my crank shafts has the standard crank code of 2A717. The other has AT38/A/X

Any idea what this means? Both blocks are 948 - one is standard a35. The other may be from a Sprite or a bitsa as it had 997 Cooper Cam, 997 Cooper conrods and a nice small bore head.

Either crank will need grinding so wondering if the 2nd one is special.

Google has failed me so far so wondering if any of you have a good old parts book somewhere that can translate what this is.

Thanks, Andrew.

I've notice that I was reading the code from a different location to the standard crank.
The standard crank has a different number again here.
The non-standard crank part number is all but missing apart from a 7 and a 6 (The 7 is very faint so could potentially be a 9 followed by a 2 if read the other way up)

Not something like 2A828? That's Moss's part no for the MG 948 crank and seems to tie up with MG Experience forum.

Thanks Gazza but no. I don't think so. I did the pencil rubbing technique which revealed a 2.

So it is 2 9 (Unless they do lower case g) followed by a triangle with something inside it!
