Hi,
What is the difference in A7SS/A10 cam followers that they have differing part numbers, and how do you tell which is which between 67332 and 67333?
Much appreciated

Hi Peter,
the difference is head design and wight.
One have rounded head and look more massive. Wight is 58 gramms
The light ones looks a bit like a tower and is smaller in circuit at the head. 50 gramms
But I don't know the partnumbers each one.
Cheers Klaus

Ive written my post confusingly. What I meant to say was, why are the cams a set, yet have different part numbers and what is that difference? Klaus has kindly weighed them. I wish to buy new repro set and fear they will be all one type instead of two 332 and two x 333.
Thanks guys

G'day Peter. A set will have two of each. The outer two are different to the inner two due to the holding mechanism.
Cheers

Thanks Muskrat, that is exactly what I needed to know.
