  • Saginaw pump in Explorer Front Dress, for 351w

    It feels like a good time to jump back into Bronco projects, it has been a while since I have done anything other than drive it. I went out for a couple of hours driving on a twisty mountain road on Sunday and was reminded that my brakes could use some extra booster power. Add to that, my $$$ Powermaster alternator is chirping like a bird which annoys the hell out of me; and it is conveniently out of warranty. Grr...

    It occurred to me that I have access to a (free) Explorer front accessory setup. I also have a $$$ modified Saginaw 'canned ham' power steering pump from AGR, which sits in a Ford specific reservoir tank on my Econoline bracketry - which differs from the GM style reservoir that the Wild Horses bracket was designed to accommodate.

    So, killing multiple birds with one or two stones here, I am thinking about taking the Bronco apart again...

    Wild Horses makes an adapter kit to mount the Saginaw pump into the shorter Explorer front dress:
    https://www.wildhorses4x4.com/produc...ER5ENGINEPARTS

    Wild Horses explicitly states this does not work on a 351w/5.8 - there's a mismatch in mounting holes.
    I poked around on Classic for a while and found this thread, where a guy designed his own bracket to solve this problem:
    http://classicbroncos.com/forums/sho...d.php?t=275080

    So with the Wild Horses bracket, the special adapter (which the guy on Classic may still have a few spares of), the free explorer stuff, and my pump, I am part way to a pretty inexpensive conversion and a move away from my long history of bad luck with 3g alternators, while retaining my already proven AGR pump. This will also allow me to hopefully run a normal radiator hose instead of the crazy contraption that I had to rig up, to fit with my existing brackets and my generic radiator.

    Back to brakes - when I switch my steering pump into a GM dual return reservoir and mount it on the modified explorer setup, the plan is to then ditch the goofy angled afterthought of an (inadequate) vacuum booster setup in favor of a hydroboost unit, and to clean up my brake lines and make that side of the engine bay look a little nicer (and easier to service) in the process.

    I figured this would probably be worthy of a thread, to be updated with part numbers, pitures, and any weird gotchas that I encounter (and I always do encounter them). If I receive that adapter from the guy on Classic, this project will likely kick off after the holidays.

    I installed the hydroboost unit from WH. It's one of the best upgrades I've done to my Bronco. When I rebuilt my steering box I upgraded to a Delphi dual return pump. It makes for an easy and clean installation.

      Is your pump mounted in the explorer accessory bracket/wild horses adaptor?
      I am looking at the amount of space that I'd gain from moving to those brackets and it seems like something I need to do. I may even move to a clutch fan with that setup mainly because I like the reliability of mechanical fans. My electric fan has been good but it is sort of an Achilles heel.

        I'm running a stock accessory belt and pulley system. I am running the WH bracket for the Delphi pump.With the dual return pump the bracket has to be notched to clear the pump. You also have to run one size larger belt.

        If you change to the Exploder front dress I don't know what you have to do. If you want I can try and snap a pic for you.

          Yep I am going with the Explorer front dress, that is half of why I started this thread.

          FYI - I contacted the member on Classic about his brackets and he does still have a few. One is coming to me soon.

          I plan to evaluate the various options for hydroboost on the EB and will probably get the WH kit. But again sometime in the new year. I am looking very forward to better braking, and hopefully a better alternator experience. First step is to get the explorer brackets and accessories installed.

            how critical is that upper idler? It looks like there would be plenty of belt around the pully on the pump without.

              I don't know, but I have the bracket coming regardless.

                I have an explorer fan and fan clutch, New in box you can have.

                  Hmm... I may have to pay you a visit soon, not that I need free parts as an excuse to go see your various projects.
                  I am undecided on whether or not I will switch to a mechanical fan, but it's definitely a consideration.

                  Thanks - we'll be in touch.

                    Parts accumulation has begun.
                    I now have the explorer front dress, wild horses Saginaw adapter, and the 351w adapter from the guy on classic. Two alternators, too.
                    Need to figure out the harmonic balancer pulley and then jump in.

                      If you're running a stock Bronco damper you can use this: https://www.wildhorses4x4.com/produc...bronco_pulleys
                      I don't know if it's the correct offset for a donor 351 damper that night have originally had a different layout, but if it's the same as a Bronco setup it should work.

                        So I finally started looking at this project a bit more today. As un-luck would have it, my 351w has a 4-bolt crankshaft pulley which doesn't match up with the 3-bolt adapter pulley sold by Wild Horses and BC Broncos.

                        I found a workaround to this issue - in the form of a 25% underdrive pulley: https://www.summitracing.com/parts/a.../model/mustang

                        That pulley diameter is around 5" where my existing crank pulley is around 6.5". I think this is a horrible solution to the problem - I cannot see running my steering pump at lower rpms being a good idea given the size of my tires and future plans for hydroboost.

                        So this leaves me with sending an explorer damper to damper dudes to have it rebalanced. I do not like this idea very much. A friend had that done and then later had his engine rebuilt - the machine shop found the damper imbalance to be off. Was it off enough to cause problems? probably not. But it was not right.

                        So I think that I may put this project farther back on my list of priorities, and start looking at mounting my new auxiliary gas tank - which in and of itself presents me with some unanticipated challenges of its own given some of my "custom" interior work... it is never easy...
