Mini Cooper Register
Ive purchased a crank but am having problems identifying it. Its got 2' mains and the journals are 1.625', and is EN40B, but i cant find an AEG number anywhere.
The only stamp visible is a 707 number. To be more precise, it is 707/641/?. I am seriosuly hoping i havent bought a duff crank!:?
It must be a Mk I/IIS crank if it really is of EN40B and for Mini. You could measure the distance between the centre of the mains and centre of the big ends. If you multiply that by a factor 2 you get the stroke, which will help you identifying which type of S crank it is. If that is about 61.9mm, then it's a 970S. If the stroke is about 68.3mm, then you have the 1071S. Otherwise, if the measurement gives about 81.3mm (for 1275S), then there are still two options. The early AEG316 is not cross-drilled, while the later spec AEG480 is.
If memory serves707/641 is an early 1071 crank.
Ok, lovely. :):)
There is also a line of green paint on one of the throws – if i could work out how to post pics ill put one up. Does this have any signifigance?
Not awareof any significance the green paint might have – unless an aid to balancing perhaps?

There's an email contact link on the home page of the site 🙂
Emailed but have had no response.
Could someone PM me his number? The frustrating thing is i spoke to him only a couple of months ago on another matter, but cant find his no in my book!
Check your PM's. 🙂
I have bought three 1071 cranks till I found one that wasn't cracked of those three I found the casting numbers ground off in aid of balancing good luck I spent way to much…But found a good one 10/10 ground. Morris cooper s 1071 needs help.
Hi all – does anybody recognise 12G82A as being a 1071 crank ? Regards Bruce
Those numbers are strange could you send a picture. Maybe I can help
Sorry to ask another crank question, but I have bought a crank with the following references :-
707 641 A
I am hoping it is a 970s crank, am I right?
I believe you have a AEG330 which is the correct number for a 970 it should be or maybe not cross drilled.
Good luck Scott
Great news . Thanks
