explorer power steering pump pressure

[777mechanic]

well i replaced the pump and it works perfect , the pump is at 50 psi and when you just touch the wheel it jumps to 800psi and stays there til you hit the stops the it pegs at 1500psi . the wheel take only 2 finger now to turn , this whole time i was bypassing hydroboost so hopefully it's operates normal then one more thing off the check list . thanks guys for the posts.

That's exactly what I did in the thread Viperwolf linked above. All the diesel CIII parts were a direct swap into the Explorer housing.

And, to clear things up, the V8 Explorers from 1996 to 2001 all had a unique CIII pump, totally different than the CII found on the V6 models, and different than CIII pumps found on other Fords. If you have the diesel CIII and the Explorer CIII side by side (and especially if you have them apart side by side) you can see the similarities- it's obvious that the Explorer pump is a CIII even though it's an oddball variant.

On a tangent, does anyone know the maximum safe operating pressure for our power steering systems? These days I've got a 4x4x2 steering box and the ubiquitous Bendix hydroboost unit. I'd like to re-install that hot-rodded pump that's been sitting in my shed for two years, but I don't want to blow anything up. Is 1800 psi too much?

the explorer pump wasn't a unique variant it was the most common c3 pump the trucks had the most rare mount with four mounting holes. the explorer had three mounts and fit every escort,explorer,taurus, and contour.

These are probably the 4 largest volume vehicles sold by ford.
I agree with you that all c3 pumps are remote reservoir. I disagree with you that all c2 pumps have attached reservoirs. A common "canned ham saginaw pump contains all of the fluid in the pump "housing". All pumps have housings that direct the fluid to the valve to create flow. Pumps that have remote reservoirs still have a housing with fluid in it but have a reservoir separate from the housing that contain the majority of the fluid. The housing can take many forms whether it is a steel(saginaw) aluminum (most imports, and some domestic), plastic(c2) or cast iron(c3,tc,cb,zf,and some imports) but when the housing doesn't contain all of the fluid and has another container for fluid it is called a remote reservoir.

1800 psi isn't to much for the gear. i have been told by my reman co. that the seals are good to at least 3000 psi like the hoses so no worries.

Thanks for the pressure info- I'll install my customized pump and report back how it performs.

Interesting on the V8 Explorer CIII pump. I had looked for crossovers to other Ford models and didn't find those. My understanding was the V8 Explorer was the only Ford model that used it. Thanks for the info.

As for CII pumps, integral or remote reservoir, I know nothing about them. Never owned one, never worked on one. So nothing to disagree with there.

what clll pump?

hey my brothers, does anyone know the year of the clll diesel power steering pump, to swap the internals with my explorer pump? Thx in advance:-*

Don't you guys love how I'm dredging up all these old Power steering threads?

Today's question is where do I buy a power steering pressure gauge - and what fittings did you use to plumb it into your high pressure side?

I have made my own Russell high pressure hoses with -6 AN fittings - and it would be great to tee into the line between my Explorer pump and the hydroboost with a gauge with -6AN fittings already on it.

Anybody sell such a thing? Grainger? McMaster Carr?

What I did: found a generic pressure gauge in my pile o' parts that went to somewhere on the far side of 2000 psi.

All my power steering & hydroboost ports are adapted to -6AN. Used the Lee Manufacturing adapter on the pump.

So, I got a mix of -6AN fittings from the local hydraulics supplier, including a tee, that I adapted to the pressure port on the pump. One leg of tee to gauge (via female pipe thread to -6AN adapter fitting), other to pressure hose. Sounds complicated, but it wasn't. All pretty standard stuff, once I had the fittings it took a couple of minutes to assemble everything. When I was done I disconnected the hose at the tee, the tee at the pump, then reconnected the hose to the pump. Done.

Lars,

How about an update on how the diesel internals swap went?

 

[mattt]

I've been running a modded Explorer pump(diesel internals) for 2+ years with no issues. Since I don't have hydro boost, I only went for a psi bump, and not a gpm bump with the rebuild. My rebuilder said he could do just the psi bump or both psi & gpm bumps.

 

[chuzie]

Who was your rebuilder? How much did it cost? Are you running a ram assist?

 

[mattt]

It's a local place in L.A. call cj. I'm not running ram assist. It was a few years ago, I don't remember what it cost because I had a few boxes and 2 pumps done all at the same time so it was a package price. I've kept the 2nd pump around as a spare, but I now see I will never need it, so I'd be willing to let it go. I suppose I should post it up.

Only issue is a former Bronco brother that I helped out and lended it to returned it to me with no pulley. He swears the pulley came back to me, but it never did....I guess the shipping gremlins removed it when it was en route between him and I. %)

 

[chuzie]

You have great timing. Already ripped my apart. Headed to get the SD pump now then the surgery begins.

 

[chuzie]

Something is not right.

Went to the salvage yard to get a pump from a 99 F-250 diesel Super Duty. They claim that the diesel variant only came with the reservoir on the pump not the remote reservoir.

First I am Not sure if that even matters in terms of the internals. Secondly, I cannot risk it because once I buy it, its mine.

Does anyone know for sure if there is a diesel variant Super Duty that has a remote reservoir.

 

[73azbronco]

I think I'm pretty sure when I was pulling reservoirs off those last week, I saw a SD with a pump that looked damn near identical to the explorer pump.

 

[chuzie]

Just got off ford site and indeed the SD diesel is only attached reservoir. Gonna start a explorer pump modification thread. I've already hijacked this one enough. Link will be forthcoming.

 

[toddz69]

As memory serves, the SD's went to a remote reservoir setup when they went to the 6.0 engines. The 7.3s definitely still have the CII pumps with integral reservoirs on them.

Todd Z.

 

[chuzie]

Oh. So im looking for the 6.0. Those are post 2003 if memory serves.

 

[mattt]

Yes, 6.0's started in mid 2003. You may find 7.3 or 6.0 diesels in 2003 trucks. I dont know the particulars of what parts to swap from the diesel ps pump to the explorer, I just know that it works after having mine done by a rebuild shop.

 

[chuzie]

Here is a write-up I did on the modification.
