H-boost no brakes or pwr Steering

[ksagis]

I've heard from some other forum members that if the Hblock is offcenter it can cause bleeding issues. And regardless of being on or off center, the geometry of the Hblock looks a little nasty to me to get air out due to dead legs. Higher volume flow seems to be one's friend to entrain any trapped air.

Edit: ignore comment above, I reread your post and see you said Hboost, not Hblock.

I played around with various methods of bleeding brakes and I have two that I now prefer. The one that I call the "Peanut-Butter Bleeder" because I made it from a Laura Scudders jar, and a pressure bleeder made specifically to push fluid in at the bleed screws.

The peanut butter bleed has pieces of copper tubing epoxied into the lid that allow intake manifold vacuum to pull brake fluid out of the bleed screws. Or I can use it as just a catch-can for more usual bleeding methods.

The pressure bleeder could be copied using a dead fire extinguisher, if it has an aluminum valve rather than a plastic valve. It does need a low pressure (0-10 psi) air regulator to work best.

Can do a deeper dive on either of both if there is interest.

Call Lee Power steering they will get you straight on the right adapter.

I think it is the Pwr steering pump I rebuilt from the explorer front dress kit I bought. Everything on the kit needed to be replaced/rebuilt except the brackets.
The pump doesn't make any noise whatsoever so it is gonna get changed out tomorrow.
I have the Lee adapter fitting for the pump and H-Boost. The fitting has a washer that has almost a conical shape to it. Does it matter which way the washer is installed?

You do know that a quiet PS pump is a goal, not a sign of a problem, right?
LOL......
Can you temporarily install a pressure gauge on the pump's outlet? You'll need a 2ksi gauge at minimum as you should see somewhere between 1200 and 1700 psi output pressure. The Lee PS built Saginaw T II pump on the Wagon is stamped 3.0 GPM, I can't recall if the pressure is stamped as well, but I do recall being told that for PS systems with H-Bs that the bump up both the pressure and the volume of the pump. I'll look at it and report back. Point is that I told them it was for a system with an H-B unit and they adjust both appropriately.

If it is not leaking at that washer the odds are pretty good that you installed it in the correct orientation.

I looked at the Lee PS built PS pump on the Wagon (see link in sig, not an Explorer pump) and it is clearly stamped "1500" and "3.0"

The pressure only builds when the hydraulic system is loaded. Otherwise it is a freeflow, no real pressure except a couple PSI from line restrictions.

So pressure transducer and data-logging required? Or just someone to cause pressure spikes and someone observant looking at a gauge?
