Anyone know the difference between the following two water pump pulleys?
C5AE-8509-B
C5OE-8509-A
Although the 1st one is a "Ford" part and the 2nd one is a "Fairlane" part, they are both listed as being suitable and used on '65 & '66 Mustangs. Anyone know if they were different in any way?
Thanks in advance.
The C5OE pulley goes straight back from the face of the pulley at the water pump hub to the pulley itself. The C5AE pulley has an outward taper to the pulley about 1/2 way back from the face at the hub. The C5OE pulley was designed to clear the P/S belt that ran from the crank pulley direct to the P/S pump. The C5AE pulley was an interference to the belt due to the taper. If you email me, I can send you a picture of them side by side for comparison as I have both of them in stock.

Fred. Thanks for the info, I've sent you my email address.
So, that means if the car DOESN'T have power steering it should have the C5AE and if it DOES have power steering it should have the C5OE? And, does the interference to the belt with the taper on the pulley make any real difference? Thanks.
Believe Bob's book covers this. If you don't have a copy, it is highly recommended to add it to your library!
Actually I ordered this book from Amazon a couple of days ago because I saw it had detail on this subject (and others obviously). Thanks.
The Ford parts book calls for the C5OE pulley but I have mostly seen the C5AE pulleys on 65 and 66 Hipos as they do not have a power steering belt issue. The pictures that I sent you Sam clearly show the differences.

Fred. Thanks for the pictures, it's completely clear. The C5AE appears to be a more robust design as the taper out to the belt running surface is more sympathetic to where the bending moment on the pulley will be. I'll drop you back an email tonight. Sam
I could not have explained it as well as you did Sam.
