Hello, I ended up with a bent water pump pulley on my 312 when the previous pump shaft broke. Been having some trouble finding a replacement. It has a 5/8 center shaft hole, pulley diameter is just a bit larger than 6 3/4 and height is 2 7/16, standard Ford 4 bolt attaching pattern. Part number is B7A 8509 C. Larger more common 7 3/8 dia pulley hits the crank pulley. Anybody have one of these? Thanks
You might have to change the crank pulley and use the more common wp pulley.
Good luck,
Ron.
Thanks Ron but I'd rather not turn an easy four bolt job into a bigger job! I know these things are out there, just a matter of finding one, swap meets are full of mustang and 60's/70's stuff, one guy told me he stopped bringing y block stuff cause nobody knows what it is. NOS sources seem to have sold out of these so I think there is someone with a nos or used one hanging around waiting for a connect! Appreciate the help!

It doesn't look too bad. You might be able to straighten it.
I'd suggest you look up Stillwell's Obsolete Parts in Evansville In. and ask Greg Stillwell if he has one. He specializes in Ford parts.You never know...........he may just have one.
GOOGLE ECG-8509-F3 and you should come across one
Thanks, this one might work, though from my initial search it looks to be a bit shorter than the one I have, might have to make a spacer. I'll be chasing the other sources this week, will keep you posted, still open to anybody finding one ! Great help guys, thanks again!

You're not sure of the PN? Do you see a STAMPING ID NO on the pulley?
That B7A-C part # is spec'd for extra cooling package. That's probably why it is hard to find.

I think he means after seeing a photo of the B7A 8509-C, he thought it looked too short. I posted the catalog page so he can measure his to hopefully find the needed one.
Hope it helps in his search. I know how he feels.
Thanks again for the help guys, no stamping numbers on the part I have, I picked the part number from the parts book, same pages shown, extra cooling makes sense as I was running an A/C and plan to go back to that. I don't have any dimension specs on the ECG 8509 F3 other than people measuring it as a little bigger in diameter, over 7"
and a little shorter on the height.

If you look at the catalog excerpts I posted, it will give the dimensions so you can compare with your damaged pulley. ECG-8509-F3 is an STAMPING ID NO, not an actual PN.
I think I may be confusing you.
Yes, we are back on track, I was confusing the stamping number with a part number, though I thought it did look odd! So back to those pages, looks to me like the two closest to what I have are B7A 8509 C and B5A-8509-D, the one with the stamping number you gave is close as well but may be a bit oversize in dia. I know that 7.37 in dia has interference, I have one that I bought before I realized how detailed this all was. I suspect it is B7A 8509 B. Do you know the part number for the one you referenced with the stamping ID?
Thanks, sorry for the confusion.
jfyi....B7A prefix is the code for 1957, B5A is the code for 1955.Any part number beginning with B7A is a 1957 part. With that said I'm not 100% sure if part numbers used over multiple years continued using the part number given to it on it's first year of usage, or if it changed prefixes as the years went by. Keeping the same prefix would make the most sense.
Not trying to add to the confusion, just bringing up the fact that even though a part number has a B5A prefix indicating 1955, it still may be a part used in '57
Rich, you are basically correct. The problem with Ford part numbers is they change them too often.
That same B5A or B7A part number could be changed to C1A a few years later as an example. Ford part numbers even drive Ford parts men in the parts department crazy at times :005:
Yes, thank heaven for the Text and Illustrations books, have owned both for decades. You are also right that a preceding year number could have been used later, was why I first focused only on the B7A part but with the description and to widen potential success the B5A number comes into play.

The STAMPING ID NO I gave was described by the EvilBay seller of the B7A 8509-C pulley.
When FORD cataloging gives AC, that is meant as FORD ASSEMBLY or possibly DEALER INSTALL AC, not aftermarket. The damaged pulley you have, is it correct for the application? All you have to do is take the measurements from the take-off pulley and match it with the sizing chart in the parts listing.
Is the engine original to the car?
Hi guys, just wanted to let you know I did finally find the correct replacement water pump pulley for my 312. It was indeed the B5A 8509 D and I ended up finding a guy who happened to have a NOS one. Interesting that it was manufactured differently than my damaged part which probably indicates that Ford may have used multiple sources for the part spec. Where mine had a ridge where the nose was fit into the sheave, this one looks smooth all the way down. So all in all a happy ending, and I am looking forward to getting this project back on the road as the pandemic winds down. All the best to you all and thanks for your assistance.
