I just removed my camshaft from my 1966 Austin Cooper S.
It is a pin drive camshaft which I am told is original for the “S”.
I do not see any markings.
I understand somewhere there are pictures or ways to identify the cam visually.
Any help would be appreciated.

3/8 or 1/2 lobes?

My camshaft has 1/2” lobes.

Here's a snip of the parts manual showing the changeover point to the 510 camshaft.

If it’s a 66 car it should have (if original) an Aeg510, which has 1/2 inch lobes and 1 ring on it I seem to recall.

I’m pretty sure the 148 doesn’t have any identifying marks whereas, as previously said, the 510 has one ring.

148 don't have any marks I can confirm.

AEG 630, same spec as all 998 Coopers (3/8" Lobe the bigger motors had 1/2" Lobes), Cooper S till changeover to AEG510, and, 1100 and 1300 engines.....

Thanks all.

Looks like I have the original camshaft - AEG510.
My engine (9FSAY42201) is beyond the changeover point of 9FSAY40006.
My camshaft has 1/2” lobes, pin drive, 1 ring.



I sent my camshaft to Delta Cams (Tacoma, Washington, USA) and it was returned with a red band.
What does this designate?

Only Delta Cams would know that........
