Saginaw Pump II by Boss

[bossind]

Another Sag Pump Install - pull up a seat and enjoy.

Because of my last sag install you all know I already have one of these on my Bronco, so lets do a little recap.

-Saginaw pump and bracket come from 1987-1997 ford 302/351 vans.

-302 and 351 are the same bracket so it won't matter which one you get.

-Your bronco pressure line will not work, you need the one that belongs to the donor. (steering boxes have the same fitting, pumps do not)

-You can buy a saginaw pump new that fits your bronco bracket - just another option for you than doing this. Link for ya on that


I bought a new pump off of ebay and because I have a couple extra sag pumps and brackets I'm going to build on one of those brackets, get it ready and than swap it into my bronco.

Something else you should know about my bronco so you'll understand why I'm doing the things I'm about to do. My bronco has Hydro Boost brakes and a hydraulic winch, so with steering I have 3 devices on the one pump.:shocked

Lets look at what I have picked up. Pump is for an F350, Reservoir is from a 1998 F150 and the bracket came off of a 96 E250 Van.


Notice the nipple on the pump for the reservoir hook up.


Ok lets start by removing the old pump from the bracket. I'm going to use this rechargeable impact gun from Makita


and this pump pulley puller. Pulley is pressed on, there is no bolt holding it.


Place on clam from the puller around the ridge on the pulley.


Insert the threaded shaft into the clam


Install the second clam and slide the sleeve to keep everything to geather.


Use your impact gun and it'll come right off.


Now remove these 3 13mm bolts and the pump will drop right out.




Now is a good time to clean up the bracket, I have an enclosed sand blaster and it makes short work of this.




After about 10 minutes it looks like this.


This is where I'm going to leave it for today, but stay tune cause we are going to do some powder coating! :chili:

January 30th 2008

Had no luck sourcing powder coating in town so I ordered some off of ebay. Hope 10bucks for 2lbs of gray is a good buy. Anyway because of 3 of these brackets and I will be performing an engine swap in the future I will finish this install with paint, and will return in a couple weeks do do the powder coating on one of the other brackets.

So here is the bracket now all cleaned up and the castings trimmed off.


I sprayed some Dupli Color wheel paint, this stuff goes on great and drys fast.




Heres the paint code.


back tonight with more.

............................................

Back from the shop.

Sand blasted the pulley and hit it with the same paint.




Mounted the new pump into the bracket


This is the pulley install tool


It threads into the shaft and pulls the pulley back on.




Pulley pressed back on




Ready to install on the truck.

Today I started on the bracket that will hold the reservoir.

I'm going to mount the reservoir off of 2 bolts used bu the AC, this will place the reservoir directly over the pump.


Bit off a tight fit, it'll have to be just right to work and have all the lines clear.


I'll use some 1" x 5.5" angle iron on for the bracket, this will mount on the A/C pump.


The AC bolts are on 3" centers, I punch the angle iron to help guild the drill bilt


I used a drill press only because it was right there, you can use a hand drill for this.


This is what it should look like when your done drilling.


Here I have the OEM bracket from the F150, to save time I will reuse some of this.


First I need to cut off what I don't need, I'll cut right on this bend.




Test fit, notice I only tacked welded the OEM bracket to the angle iron.


Not bad, I think I can live with that so I'll finish the weld.


Thats all for today.

Saturday 9th 2008

Started the morning with a Tim Coffee - Double Double (2 sugar - 2 Cream)


First off I finished the bracket


Rounded off all the edges so it'll be flesh friendly


Remove the


Disconnect the mass air from its harness


release the air cleaner latches - there are 3




Stuff a rag or paper towel into the breather, we don't want something to end up in there.


We now have clear access to the pump and bracket


Remove the belt, I was able to do this by hand.


Disconnect the wires going to the AC




Place a pan underneath to catch the PS fluid


Unhook the lines to the old pump


Remove the 4 10mm bolts holding the AC compressor


The AC lines will flex some, I used some copper wire to hold it up and out of the way.


The bracket is held in place by 3 14mm bolts, remove them.


With the bolts removed you can remove the pump and bracket.


Because I'm using braided lines I need to swap over this adapter from the old pump into the new.


Install the new bracket and pump, reinstall the 3 14mm bolts


Reinstall the AC compressor leaving the bottom 2 bolts out.


Install the reservoir bracket.




Place the reservoir into the bracket


Install the hose that goes to the pump


Hook up return hoses - I have 2, one return from the steering box and one from the hydro booter.


Reinstall the belt


and the air breather, connect all the electrical that you unhook


Disconnect the drag link - this is the best way to remove all aire from the system

so is the new pump a higher flow unit??? or did you need to do this to accommodate the extra reservoir??, first when i seen the post i thought you were adding a second pump to the system or something

did you see this link before , it makes a stock pump flow better according to them , it made a world of difference to steering on my rig though , freddie did the same thing with his pump , hes running a mile marker hydro winch and turning 40"s pretty easily

nice clean work!!!!!

is your new pump a higher flow unit??, or did you do this to accomidate the extra reservoir, first when i saw the post i thought you were adding a second pump to run all the hydro stuff?

did you see this link?? it is suppose to make a stock pump flow better , it made a world of difference to the steering on my rig. freddie did the same thing to his pump and he runs the 12000 hydro winch and turns 40" tires relativly easily

I had already upgraded my pump a year or so ago with a used saginaw pump (they flow alot better than the OEM ford ones) it started leaking this year. So faced with having to replace it I decided I wanted something I can see the fluid level at a glance.

I thought about running another pump for the winch but the saginaw really has no problem meeting the needs.

Lets see what this pump can do.




I bought these adapters to hook up a pressure gauge.







Took like 20seconds to install, AN fittings rock! :beer

So tomorrow I'll pick up that gauge and will report back.

Ok so here are the results


Test was done with the engine at idle, 138PSI is the normal pressure with no load, 1431PSI is when I turned the wheel all the may to the stops till I hear the relief valve hissing. I repeated this 5 times with the same results, than I increased RPM and it made no difference for the max - which is logical cause thats controlled by the relief valve and if you can open at idle than max PSI has been reacher. Min PSI did increase to 171PSI with an RPM increase.

So I'm happy with the results and see no reason to mod this pump, according to milemarker results/tests I can pull 12000LBS at 1400PSI with the winch.
