86 Bronco power steering pump

[Bigfunford]

I just bought an '86 Bronco. The truck has 6 inches of lift and 36x12.50s on it. The power steering pump is shot and the previous owner was telling me that he had heard that the stock pumps won't hold that big of a tire with serious off-roading, but that he had heard about people getting the pumps from the 78-79 models and they would hold up to 40s. Is there any truth in this? If not what do y'all recommend? Thanks in advance for any help.

Swap (Broncoair.com) in a 93

D wrires; "...The first task you need to do is get a bracket for the sag pump since they mount different than the stock crap pump. I hit the local junk yard to find a pump and bracket, better just pull the pump too since your going to need a core. You can nab a bracket out of any 87-96 Ford Econoline van with a 5.0 or 5.8 engine. I think I payed somewhere around 40bucks for the whole deal which included the bracket, pump, and pulley. You can also get the bracket new from ford(PN F4UZ3C511A) for about 60bucks. Now that you have your new bracket all cleaned up and ready to install go down and pick up a new saginaw pump or use the junk yard pump, also pick up a high pressure line for the same E-series van since your stock one isnt going to work due to the differnce in fittings on the sag pump. Also your going to need some longer bolts and spacers for the york bracket. I used 6" long 10mm bolts and a 1.5" spacer for the bracket, this raises it just enough to get the cap off. The hardest part of this swap is getting the broncoair pulley to work with the sag pump since the shaft size is differnt. Any machine shop should be able to drill out the pulley for you just take the stock pulley from the sag pump to compare too, it has to be within .002" since its a pressed fit onto the pump. Also rent yourself a pulley remover and beef up at the gym before you go to take the pulley off. .." read more in the Link

TIPS by ZACH

what to get your pump from

look for ford vans. 1/2ton, 3/4 or 1 tons, its all the same.

theres is one funky year to watch out for though!

the 87 vans and broncos use a much different AC compresser mount, that i cannot see easily adapated to fit a 88 or newer truck.....

88 or later is the optimum year to look for, i have seen i think an 86 serpentine bel tthat i have pulled one from that worked the same.

-second, the tools you need for the pump removal

hammer- great for shock treatment of stuck bolts

pipe- great for extra leverage, also good for holding up the hood.

Vise grips- great for clamping on siezed HP hose fittings and then hitting the end of vice grip with the hammer to break it loose. also removes any other bolts/ washer or thing in the way to the pump

so again, in recall watch out for 1987 van pumps, as the AC bracket is WAY different, and watch out for the HP line on some vans(dont know the year) on the steering box that is a 11/16s fitting

info on the pumps in general

-in general all the saginaw pumps are the same

-it does use a different pulley than your old pump, so be aware of that you cannot just switch the two

-some newer saginaws are metric bolts, so be aware if you try bolting them using your old hardware into your saginaw bracket(this is when you where to replace a bad van saginaw pump with a junkyard pump of another brand) newer chevys also use a funky shapped resivoir and are metric

-when replacing just a bad pump t ry to buy it with the resivoir if you can. brand new with resivoir is about $105. without the resiboir it is $45 or so, but believe me, it is not worth it! i tried two different rebuilt pumps, and i could not make either fit into the resivoir on the chevy i replaced the saginaw on this week.

ford install issues.

Yes, you need to run a longer serpentine belt! you "Can" make it fit qith a stock belt, but this is a tight fit and applying lots of extra side load ot your other accesories bearings(ALT, Water pump, Saginaw pump)

the install isntructions

-Remove your airbox hoses(makes it easier)

-remove the serpetine belt

-remove your low pressure line from the steering box, and let the old fluid drain out.

-while it is draining, disconnect the AC electrical connection that is for the magnetic clutch

-unbolt he 4 ac bolts

-"Flop" the AC compresser out of the way keeping the hoses connected

-unscrew the HP(high pressure) line at the steering box and let it drain out

-remove the 3 bolts that hold the bracket to the block. 302's i think use a 4th stud

-pull out the whole bracket and pump

-bolt the saginaw pump/bracket to the block

-connect your HP and LP hoses to the connect spot on the block. yuou use the van HP hose and fitting and put it into th ebronco steering box. for ht elow pressure how, just slide the rubber hose off the old ford pump, and clamp it down on the return line coing out of the saginaw pump. then put the hose back into the steering box. techinallyt you didnt have to remove the LP hose from the steering box, but i find it easier

-now its time to dr4ill out the AC compresser

-after its drilled, bolt it to the bracket

-plug in the AC electrical connection

-install the new aprox 1-1/5" longer serpentine belt(on the pre 93's, zilla has the belt number for the later ones, i will find it)

-fill your PS pump with fluid

-make shure everything is put on the truck and tightened(i leave the Airbox hoses off at this time)

start it up for about 10 seconds, then shut the truck off. go check/ refill the PS pump, also check to make shure there was no sign of major leakage

- start it again, and cycle the steering. i do this with the truck weight on it, but mine is hydro assist, and has lots of steering power. i recomend you have it on jackstands, or the draglink disconected, or roll the truck forewards oem while doing it.

- expect the pump to whine an dhowl some at you when you do this. if it gets real loud then your low on fluid.

- after cycling the steering, check/refill the pump with fluid. this is normal it goes down till all the air is bleed from th system.

-now let it run and check for any small laks from the pump, of any of the fittings/hose connections.

-put it all toghether, give it a drive or two around the block, and double check the steering fluid level again.

done, your steering swap is done.

expect about an hour to an hour and half to do the swap on your bronco if you are pretty mechnically inclined. adjust down or up of there based on your ability.

Nothing is hard about this, just takes a little time, and geting PS fluid all on your arms.

And if you already dont know, i sell used pumps with the bracket, hose, and pulley for $55 plus shipping

PM me if you need one. lots of people have bought from me, so far no complaints about anything.

The easiest swap is to get one from a E250 of the same year as your truck. That way you can get all the parts you need along with it like the mounting bracket, hoses and pully. I did the swap the hard way using the bracket from a 78. That meant a little fabricating and merging the bracket from my pump with the 78 bracket as well as make my own high pressure hose.

Good luck,

I usually place the quotation (") marks in anything that is attributed to another person but I didn't on this occasion.

Be well!

Does it have to be the exact same year? I found a junkyard down the road that has one from an '85 diesel van for $50. Will that work? If not does anybody know where I can buy what I need? I'm having a hard time tracking down exactly what I need.

 

[Seabronc]

There is no doubt in my mind that the pump will work, not so sure about the bracket, probably the high pressure line. The easiest swap is from an E150 or E260 with the same engine as you. Take the mounting bracket and High pressure hose with it. I'm not sure that the bracket from a diesel is the same, looks like it in the diagram. If you can fabricate, then you may be able to convert the bracket like I did when I used a 78 pump and bracket. Here is a couple of exploded views out of the 83 Shop Manual.

Good luck,

would a re manufactured pump from an auto parts store work?, it looks like a canned ham saginaw pump and its only 39 bucks i dont know if it actually is or isnt, since the junk yards around here want $35 might as well get a new one.

yo,

First let me apologize for not posting this First in my first reply;

Swap in an 83 Source: by my friend here, Seabronc (Rosie, Fred W) at Ford Bronco Zone Forums

as that new TV ad says.. probablyyyy

Here ya go

Here are some user reveiews;

bought my pump from advance auto for 45 bucks with a mil discount and 30 bucks for the core charge. They will take back any pump for the core refund. They didnt have it in stock but they shipped it to my house in two days and I got it in the mail a day after I ordered it. This thing is nice. Get the CARDONE!

I checked the fitting and everything is bolt in for a 5.0 1994 bronco with a/c. It even used the same high pressure line. It comes with the elbow as was stated before this is 100 percent bolt on.

Removed 4 bolts holding the cooling fan to the water pump and pulley. by foxbravo

"...Cardone part #20-6244; ..It's a Saginaw pump that mounts to the stock Ford mounting bracket and uses the stock Ford pulley and stock hoses. It's a direct bolt in deal.
