69 Boss 302 Power Steering
« on: June 22, 2023, 08:27:17 PM »
Thank You for that,  This has a BK pump (return points at the ground), so i'm sure it was not correct as the return from cooler has to make serious bends to attach to pump.
If I'm correct, the same pump end pressure will be same as 351W for 69.  C7AA Aluminum cradle, Non hole flat steel, and the BK style indexing bracket???

I believe so.

I have a BK pump here as well as an original 69 cooler. Just looking at them I do not see how the return hose would work especially with the long leg of the 69 cooler vs the 70 style.

That is what this has.  A BK pump which means the cooler hose has to attach to the down pointing return on the pump, make a 180 turn to get to the cooler.  Seems odd.
The manual says BF pump (return nearly straight back of pump).   So is your pump and this pump wrong as they are are BK, and not BF?
Did the 69 B2 have both?

So Hopey has A BK pump, you have a BK, this one I'm rebuilding is a BK, then it stands to reason they all were BK's as the 351W had.
The literature in the above document must be incorrect as it states a BF pump.
Who wrote this document?  FORD MPC --who is MPC?

Well that damn sure explains it.
As most know I have stated it was the 60's, we lived it,  the 60's were happy times, free thinking, free love, a free use for some of the mind altering things that were available.
I think most, a good many of the Ford engineers were free thinker that use LSD. SOMETHING had to make them do the many stupid things, changes they did.

And list parts currently (at the time of printing) available that could be used to service Ford vehicles

Actually, no. It was written by clerks based on a lot of input from design engineers, sometime conflicting, well after the design were released for production, as design engineers were busy on the next years' production. Labeled "For Car Parts", but called in slang the " MPC", it was published roughly at the time of the introduction of the first vehicles of that model year to dealers and that was intended to be used by those dealers' service departments. Assembly line engineers also gave their initial input, and, as we have seen, made changes as the production year went on. There were new product prototypes made for publicity, Ford Marketing too - and remember, the Mustang was initially called the "Special Falcon". I have seen pictures of what is obvious to us, a Mustang, but labeled as a "Cougar".
