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!

Tomorrow I should be able to get some shots of the installed pump. Let me just say thing. When pulling someting in a bone yard under the hot baking sun, remember to make sure you put all of your tools back in your bag! Right now there are four lonely wrenches on a econoline core support.

Here are a few more photos. The pump is runing great. However, my high pressure line is leaking at the steering box. Gotta fix that. There is just enough adjustment in the pump to use the existing belt. I haven't run it long enough to see if it will squeal when the engine is warmed up.

EDIT: I finally got my lazy butt to remember to check 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. If I can't jerry rig it somehow I'll probably swap out the whole line.


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.

neato, so that bracket is from the same year van as the pump?? do you happen to know if the same trick will work for serpentine?

[Aikidoka]

There's some bolt size trickiness to the serpentine swap. Run a search for saginaw pump in the tech article forum. You'll find one or two serpentine swap. In my case the bracket that went on the water pump is off the donor van. I got lucky in the fact that the large upper bracket for the A/C has a hole for either style in the lower right.

I was in a salvage yard today. I found a 16mm Snap-On wrench on a Ford truck core support. When I first saw it, I figured "China Junk" It was the second time I walked by it, I did a double take and it was Snap-On, so I adopted it.

[Aikidoka]

Yeah, they were all hand me downs and I can't even remember what brand they are.

Hmm thats pretty sweet to know. I may have to go searching for that stuff soon. PLus I need an AC pump for my OBA.

Finally remembered to compare the E150 and Bronco P/S belts. E150 is a little shorter so I modified my instructions to include getting a new or the donor's belt.
