V-Belt Saginaw swap (no cutting/grinding!)

[Aikidoka]

I just picked up a saginaw to swap into my 86 Bronco.  I found out a few more things that can avoid some cutting/grinding.  My donor vehicle was a mid 80's carbed Ford Econoline.  It was also a v-belt system.  I have a 351W.  The donor had a V8, I think it was a 302, but I didn't really care too much.  

What you'll need.
Pump and pump bracket.
Belt if it's in good condition. (It's shorter than the stock Bronco belt)
The long bolt in the top hole of the pump bracket and it's spacer.
The bracket connecting the pump bracket to the water pump.
The high pressure line.  (The old one is the same size and threads, but the end connection is shaped differently and will not work.)

The engine bracket that holds the A/C has two holes in the bottom right corner for the power steering pump.  It has one if you have the crappy stock pump, and a lower one for the saginaw pump.  If you have gotten the extra bracket off the van, you will not need to modify your original bracket.  I still haven't been able to get my old high pressure line off the steering box.   


Here you can see the two bolts showing the holes.  The upper right one is the original pump bracket hole.  The lower left one is for the saginaw pump bracket.


Another shot with the bolts removed.


Both brackets from the water pump.  Top is saginaw, bottom is stock bronco pump.


Here they are with water pump bolt holes matched to show the difference.  One on top is from the van.


Here's the bracket installed, showing the top right hole lining up with the extra one.  You can see it goes into the lower hole on the bracket attached to the head.  Now I know I never forgot a bolt when installing the rebuilt engine!

Here are a few more photos.  The pump is runing great.  However, my high pressure line is leaking at the steering box.  I checked the E150 belt size against the Bronco's.  It's about 1.5" shorter.  You can get the one of the donor if it's in good condition or buy a new one.  It will tension up much better than the stock Bronco one.


Pump installed.



My leak.  Bottom line.  The leak is where the line comes out of the fitting on the end.  I went and got a new line for the donor vehicle and bent it until if fit properly.


EDIT:  For those interested in doing steel braided lines, the fitting to use on the sag is a #6 to 16mm x 1.5 O-ring.
