I'm interested in eventually doing a Saginaw pump swap on my 86 F250 2wd 351W, I've been having a hard time finding the kit on the internet and how much it costs, can anyone in here lead me in the direction to a conversion kit for it?


Thanks

 

I have asked this question before and never got a good answer that I remember. Why do people do this conversion? Does this pump have more flow or more pressure? Do our trucks need this when they have larger tires or what?

 

People do the conversion mainly to eliminate the power steering pump noise heard with the factory F-series style pumps that are prone to aeration (personally, the only noise I hear from mine is the "PSSSSSSSSSHHHH" sound when you turn the tires. Every truck I've ever heard has a pump that makes this noise, Dodge, Ford, and Chevy).

The Saginaw pump does have more flow and higher pressure, and is a popular swap on 4x4 trucks in the Offroad forum on here. It really helps turning not necessarily taller tires, but wider tires they say.

To do the conversion, you'd need the power steering pump brackets, the pump and pulley, and I'm not sure if you need to find it or not, but the pressure hose. I think the pressure hose fittings are the same size and TPI, not sure.

But yes, the parts are on E-series vans and are bolt on to F-series trucks. To my knowledge, nobody makes a specific conversion kit to a Saginaw pump for these trucks. Brackets come from the junk yards, pumps and pressure hoses as well as belts can come from the local auto store if you want new or "newly remanufactured".

Personally, my new Fenco pump was $39.99, two things of power steering fluid with stop leak for 5 bucks, and I was good to go (after replacing the 7$ seal of course).

I personally don't see any gain on a stock 2wd or 4wd truck, unless the noise really bothers you. My Fenco power steering pump meant for F-series trucks, the prone to aeration design, is silent at idle.

 

The main reason is the whine that many Ford pumps like to make, mine does it as well. I have had many that did. I don't know what the difference is, but the Saginaw pumps only make the noise when they get low. That is the noise the Ford pumps tend to make even when full.

 

The reason why I want to use a saginaw pump is because that noise coming from the Ford pump annoys the crap out of me, it's loud. And I'm pretty sure my pump is getting kinda tired,(230,000 miles) it still works fine but the noise it makes is fairly loud. My dad has a GM style (looks like a saginaw) pump on our Dodge van, it's been on there for 25 years and works great. Doesn't make NEAR the noise my Ford pump does.

 

Actually I changed my mind on the pump, I think now I"ll just rebuilt it my self and run a synthetic oil in it. Now I've been reading, there supposed to take a type F transmission fluid, anyone know if I can just use a synthetic ATF? reason why I want to use a synthetic is because I've read that it makes the pump's whine go away. Or a synthetic type F? which I'm having a hard time finding.

 

Type F is a very old standard.
Ford used it up through the 1970's.
Type F is still available, and marketed by Motorcraft.
It is different in that it has NO friction modifiers.

 

I am using Mobil 1 Synthetic ATF in the power steering. It is in my Superduty and the 82. Shuts the pump up pretty quick. The Wife's Focus had a whining pump, drained the fluid, and refilled with syn ATF and after bleeding it out, quiet.

 

Does the type of ATF even matter in these pumps? and how much did it take you to fill the system after the system was drained?

 

The 82 took around 2 qts. The Superduty took 4 qts due to the cooler.

 

My truck has a PS cooler so it should take more, probably more like 3-4 then. I'm looking for a synthetic ATF other than mobil1 (not a fan of that brand) and something a little cheaper than it too, got any recommendations?

 

Merc V in any brand will be synthetic.

 

I guess that's what I'll use in it then.
