test & tune
Its done, i went for a cruise about a half hour ago. It shimmies at 75!
It is night & day better than it was before. The slop in the old box was damn near the whole problem. Its a little twitchy, might be toed in a smidge? Its god damned cold outside, theyre (big) old bias plys, and its got a locker in the rear. Its not gonna be perfect!
I still want to triple check the toe-in tho and see if i can get dialed in a little better.
So just cruising down the road, i cant tell a difference in the power of the box with the way Redhead has it ported, as opposed to the way PSC did it. I always thought porting the control valve was the 'correct' way to do it, but RedHead knows a lot more about this stuff than i do! The real test will be the next time i get a chance to play on some rocks with the tires aired down.
Got my old PSC ported box out:
New redhead box, unfortunately ports are in a different place:
The box is in. It was sleeting! So i didnt get a good pic. Im working on new hydraulic hoses now, hopefully have both done & installed tomorrow so i can bleed it and resume the front end alignment.
Passed inspection last week!
Also, i finally figured out how to properly adjust the Eldorado calipers. Turns out theres a really easy way to adjust them that i guess most people dont know? I certainly didnt. Check this YT video out.
Ok, so now that youve watched that, you should know: I just followed that and adjusted both of my calipers, in about 30 minutes. With the tires still on, on the ground.
Plenty of room to swing a wrench:
Push the lever down until its starting to apply the parking brake, and this is the gap i have them adjusted to:
100% done with tires still touching the ground.
Now, here's the important part: When setting the parking brake, make damn sure your other foot is on the brake pedal!!!!! I cant stress this enough. The caliper ratchets. Thats how it locks the brake, and thats how it self adjusts. But! It only moves a very small amount at a time. You have to have the caliper already clamped on the rotor when you set the parking brake. If you dont, it wont be tight enough, and it wont hold.
So, if i set it w/o my foot on the brake, itll power thru at idle. If i pump the pedal up a few times and then set the parking brake while im still holding the brake pedal, it holds great.
I read all sorts of articles on adjusting these, and never once saw anyone mention holding the brake when setting parking brake, but it makes a huge difference.
So now im still tinkering with the front end alignment.
Im not happy with it. Flat spotted bias plys (in the winter no less) arent helping. I do have some slop in the steering box which also isnt helping, so this happened:
Redhead #3! This one ported for hydro assist, to replace my 14 year old ported box from PSC.
Hopefully the weather holds, and i can start the swap tomorrow.
Got scared there for a second
I started throwing codes in the diesel recently, only i didnt know what they were!
As im sure anyone with an OBS 7.3L knows, the OBD-II implementation in these trucks is pretty spotty, which made this one a little frustrating to solve. I started getting a CEL that would appear & disappear and not throw a code (confirmed or pending), but the idle would change when it set. I figured ICP, so pulled the connector and sure enough there was oil in there, so i assumed that was the problem, bought a new OEM one, and slapped it in. It wasnt the problem.
I started digging a little deeper and found in Continuous Memory code P1211, "ICP Higher/Lower Than Desired (engine running)". So now im figuring either my IPR or HPOP is failing. Cant get live data from the PCM with my scanner, so i figured id just yank the IPR out and inspect it.
In case you dont know, removing this required removal of the fuel bowl. Its a fairly daunting task if you havent done it before. The last time this one was out was ~10 years ago, so i was a little rusty on how to do it, but honestly its not too bad.
I immediately noticed something funky going on. It like the silicone boot for the plug turned to goo inside the socket:
The plug for the IPR is on a short harness connected to the fuel bowl. With this removed from the truck, it was easy to inspect. And it looks like weve found a problem!
Well, surely thats our problem!
So i did some research and then called the local Ford dealer. Turns out they had the pigtail in stock, along with all the short fuel hoses you need to reinstall the fuel bowl! So i made a run up there and picked everything up. Fast forward a day, and we're ready for repair!
So here's the replacement pigtail from Ford, p/n 6E7Z-12A690-DA.
It comes in a bag with some crimps and shrink sleeving, but i opted to solder it, and use my own shrink sleeve, as i have adhesive lined
I disassembled and cleaned the IPR while it was out (i should have taken pics, but i was a bit oily at that point), and then reinstalled it. Fuel bowl went back in with all 4 hoses replaced plus the short one for the drain, and i cleaned all the sediment out of the bowl. The HPOP resevoir had been drained so i put about a half quart of new oil in there so it wouldnt try to start dry, and then fired it up!
It did initially pop a CEL, but i attribute that to there being air in the fuel & oil systems. I let it idle for a while, then turned it off/on, and problem solved! Runs great now, and no CEL.
the money shot!
...with ~3PSI in the tires, the bronco drove out of the garage on its own!
Its covered in a couple years of dust, so i washed it, and then....tires!
I did get my depth markings back on the door, but with it so overcast the pics didnt come out the best. Ill get some better pics one we have a nice sunny day!
I took it for a quick spin around the block, and it definitely needs a front end alignment! So thatll have to be monday's project, because i cant wait to cruise this thing around again!
buttoning up some loose ends
Ok not sure how this happened. But both the door, and the dash harness, have the same sex plug for the speaker
Ok thats better:
That was the last piece of the puzzle, so the door is now together!
Next on the list was the horn. Turns out every horn i have is bad! So i bought new ones off Rock Auto:
This is a pretty terrible picture. The horns are tucked up underneath the driver headlight, like they would be from the factory
After that i moved on to the wipers. Figured i should test them before i put arms on. Good idea! The motor was bad. So i had to get creative; youre supposed to remove the hood & cowl to replace it, but its actually possible to do it if youre careful
There is *just* enough room to reach in there and remove the clip to remove the arms:
So with that done, i moved it over in the garage, so id have room to work on the tailgate:
This unfortunately is not done. I ripped the whole gate back apart, check the window tracks & all the seals, greased the regulator, made sure everything is moving good, and even swapped the motor out for a different one, but its still struggling to roll the window up. Its like the old motors dont have the torque anymore to compress all those new seals. But, a new motor wont be here til wednesday/thursday, and this kinda works, so i closed the window and moved on to the next task.....
