Well - it's about the same with another Parts Store rebuilt pump - it doesn't make noise, hydroboost seems fine - but there's not much power steering assist to speak of. This box puked a bunch of fluid out of the resevior with the engine off - and turning the wheel lock to lock - but maybe...

OK... I pulled the guts out a 2005 F250 PS pump (shaft, rotor, vanes, cam body (everything - even the relief piston and spring) - and swapped into my 96 V8 Exploder pump. I even drilled out the power steering pressure switch tube that's pressed into the low side of pump - it was blocking a big...

or grind the HB to Master Cylinder rod a bit shorter - but washers may be easier on the side of the road.... Are you using the Astrovan master cylinder and pushrod or something else?

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...

THANKS DAN. I should have known that some on Pirate would already be WAAAAY deep into pumps. So it looks like the Explorer pump is really a "TC" pump according to his lingo. I wonder if the "CB" pump is the Superduty pump? I have ordered a Superduty pump and should have it in my hands in a...

Yep - that would explain it. Did you move it up to line up with the Mechanical Fan on the Explorer Assy Drive? I have a 2 inch Body Lift, and I think that my shroud is pretty centered over the fan - but it is somewhat close at the top, so I could go up maybe a 1/2 inch - which would mean...

Dan - what fitting are you using at the Explorer pump output? An "unmodified" Russell 18mm O-ring to -6AN adapter or a Lee Manf -6 AN Steel fitting? I had to cut off the o-ring portion of my Russell fitting to get any flow out of the pump - I had no HB or steering otherwise. I now think that...

A badly rebuilt Explorer pump pretty much tanked any chance I had to make the LEBC round-up this year - so I am Motivated !!! Tech article would be awesome - especially if Lars will help a newbie like me... I'd like to see the Explorer Serp Swap tech article updated too - you can't just use...

Ford Port Fuel EFI might seem expensive if you just go buy everything but I'd watch Craigslist and Ebay for 89-93 Mustang Mass Air Flow EFI parts - and check local Bronco mailing lists for parts that people are selling cheap. You don't have to buy a $500 RJM/Ryan's harness - you can rework a...

I want more than a rebuild - I want to swap the SD pump "guts" (rotor and vanes, I assume) over to the Explorer pump, and then port the Explorer housing for more flow. Basically I want to create the same "Extreme" pump that WH sells for $250-300... You can buy a rebuild kit at any Auto Parts...

Explorer Pump Upgrade? Ok - bringing this pump thread back to life because I want to wake Lars up and pick his brain for possible "el cheapo" pump upgrades. (see page 1/2 of this thread) Based on his pics earlier in this thread, I think I'm going to buy a Superduty reman pump, pull the guts...

after looking at your pics I think you've answered your own question - I think you need more travel on the HB input rod so that you get more output to the master cylinder. (Or change to a master cylinder with a bigger piston/shorter throw) so that you build pressure with less travel (but...

Will do - the pump is certainly going back to Advance - and I'll try another "rebuilt" one... I sure wish Lars would do a tech article on how to port one of these Explorer pumps to increase the flow and pressure. Hint Hint... I really don't want to buy that $300 Wild Horses Extreme pump if I...

Looks like you are running the Explorer PS Pump? If so - are you using the Lee pressure fitting/washer or at least a Russell with the bottom o-ring portion cut off? The wrong fitting can kill output from the pump. Can you bypass the HB and does your power steering work OK? (Trying to verify...

Well - now that I've dragged this thread way off topic. Your radiator must be mounted at least 2 inches higher than mine because your lower hose is WAY above the frame. I have a 2 inch BL - how much do you have? I guess the other difference could be how high you mounted your V6 Radiator - I...

I think I need help from Lars (or PSC) OK - time for the third pump. This one is off a 120K mile 96 Explorer Craigslist 5.0 pull-out. The fluid was beyond dirty. Cleaned it out as best I could and flushed it with brake cleaner and blew compressed air thru it. But this is where I need expert...

Thanks - I'd be REAL interested in what lower hose you use - but your rad looks like it is higher than mine - the outlet on my radiator is about even with the frame - and the only way I can see to run a hose without kinking is to run UNDER the frame (it looks like your hose runs ON TOP of the...

Hey Casa First (on topic) - I also have the V6 Exploder radiator I just installed with my Exploder Serp drive (and Astroboost). I covet thy Astro-van mastercylinder - because my 70s Vette Mastercylinder Cap is leaking like thru the cap... damn - but it was cheap... Are you worried about trying...

I still have BAD explorer Power Steering pump whine !!! Installed the Lee fitting and aluminum washer today - STILL HAVE BAD PUMP WHINE !!! I was running Mercon V Trans Fluid (recommended for the Explorer Pump), so I switched to Valvoline Power steering Fluid - NO CHANGE !!! It isn't too bad...

This is the info on the Explorer Pump I was looking for... Bottom line - I'm ordering the Lee Manf fitting and washer. I could probably grind more off the bottom of my Russell fitting - but it would still be an aluminum fitting with 1300-1600 PSI in it... Current situation - my "new-rebuilt"...
