so i found a hydraboost system on a 90's model f450 i belive and i purchased it from the salvage yard for 25 bucks with hoses and all intact...just wanting to know what all i need to place the unit in my 94 idi... do i just need it to place it exactly how i took it out? any tips would be apprieciated thanxs in advance.

 

By chance did you happen to get the Power Steering pump as well? The reserviors are different and if you didn't get it you might need to find one.

 

well i didnt know if i needed it seeing as my truck is serpintine belt and the truck i pulled it of had the v belt style ...actually the truck had the pump in it but again it was v belt n mine is serpentine so someone school me here

 

If I recall correctly you can remove the reservoir from the pump and attach it to your pump. From what I recall you just have to remove the fitting from the side of the pump that goes through the reservoir, and then the reservior will slide off. There is a big O-ring on the inside that seals the reservoir to the pump.

 

koo well that means another trip to the salvage yard. lol is it best to buy new seals or jus use the old ones?

 

If you can get new ones, I don't see any reason not to go ahead and put them in there. A lot of times after you disturb old seals they will start to leak even if they weren't leaking before.

 

well ill go and get the resivoir tommorow n ill have to do some searchin as to wear i can find those orings...id like to find everything and put everything in hopefully bye the end of this weekend. ive heard lots of great reviews...

 

Most parts stores carry those o-ring kits or the Ford PS pumps, pretty inexpensive too. To get the reservoir off you'll need to remove the big fitting that the high-pressure line went into, IIRC it takes a 24mm socket or wrench. Once that's off the reservoir will slide right off, may need persuasion, but it will come off. Watch out for the steering return line, it goes to a fitting on the bottom of the reservoir, don't wanna break that fitting off.

You said you already got the pressure lines, that's good. About the only place you may have issues is the master cylinder holes beeing a bit too close for the hydroboost studs, you can ream the holes with a Dremel and then it'll fit fine. Pushrod may end up a bit too short for the master cylinder you got now too, not sure if it will tho, but if it does you'll have to come up with some spacers for the piston bore - I've seen JB-weld and suitable-sized hex nuts used for that, or you can come up with something on your own, IIRC in my truck I used some allen-head bolt that I trimmed to a proper length.

 

what i will end up doing tommorow is ill get the resivor off bring that home clean all of the items have so far and ill take a couple of pixs and post what i do have ... and if for any reason i need extra items u guys can just let me know...

 

Everything should be a direct fit. The cabs are the same and the pedal assembles are the same, so I really don't see there being a problem with the pushrod. They do have different master cylinders, but I believe the bolt holes are still the same though, he may even have the 450 master cylinder from the donor truck so that doesn't really matter. This should be a much easier swap than what you did with a chevy hydraboost, this should be almost "PLUG and PLAY" as in just swapping parts without having to "rig" anything.


Goodluck on the swap, I have looked into it quite extensively for my 90 F250 and from the measurements I took it should bolt right in.

 

thanks yeah when i looked at my truck and the donor it look pretty much the same thats why i figured for the price and the work that i should go for it ... ima try n go n get the resivor for the truck today n see if i cant do some searchin for the o rings.

 

hmm. i wasnt aware that fords had hydraboost systems...but i am still rather skeptical on the reliability of them

 

As long as you have a good P/S pump and hoses, they work very well. Gives a lot more power assist than the vacuum system. And gets rid of the bulky vacuum booster under the hood

Ford has been using it in their F-Super Duty line since the late 80's. And I believe all the 99 and newer trucks are using them.

No, not that pushrod, I know that will fit just fine, tis the plunger that comes out of the hydroboost and pushes on the master cylinder piston that I was talking about. About the F350 master cylinder bolting on to the F450 hydroboost directly, I'm still not sure on that, I was under the impression that all older hydroboost have the same castings and only differ in the mounting plate for the firewall and the pushrods for the pedal and the master cylinder, but I guess he'll just have to try it and see what the deal is.

 

Direct bolt on fit.
I am running one off of a 1996 Superduty (F450) and love it.

Use your master cylinder, the Superduty has disc rear brakes.
Make sure you have the push rod in the master cylinder end of the hydraboost, it can not be bought seperately.

Pressure out of the power steering pump runs to the left side of the hydraboost pressure in fitting.
Pressure out on the hydraboost right side to the steering gear box.
Return right side of the hydraboost to the power steering pump.
Steering return line stays where it was.

Return lines have hose clamps, pressure lines have screw in fittings.



Best upgrade I have done on my brake system.
Do make sure your brake lines are in good shape, the extra pressure could blow the lines if they are weak.

Unbolt the master cylinder from the vacuum booster, tie it over to the side.
Remove the vacuum line for the booster from the vacuum tree, plug the hole for that line.
Unclip the vacuum booster push rod.
Unbolt the vacuum booster.

Install the hydraboost and bolt it up.
Hook the push rod up on the pedal lever.
Bolt the master cylinder back on the hydraboost.
Hook up the hoses.

Under 2 hours.

Use a bit of caution when you use the brakes the first couple times so you don't eat steering wheel.
