Power Steering Pump

[gandalf]

Is there any better/larger/more powerful power steering pump for my truck ('92, 7.3) than the Saginaw? I converted the brakes to hydroboost a while back, but they're still not as good as I think they should be. The truck, btw, is running a v-belt system.

A neighbor, currently finishing some major work on his 7.3 '03 truck, suggested a larger PS Pump. Is there one available, and would it help with the brakes?

I am also curious about this...

My 86 had power steering issues, since it has vacuum brakes, I simply swapped to manual steering, no complaints there, this truck is very light for a 4WD extended cab diesel pickup.

I just put a reman PS pump in my 91, which has hydroboost. It is definitely noisy, but the brakes are amazing! Better than our newer Dodges at work. I am in awe at how good they are. But this truck is an F-Super Duty, so it has huge disk brakes front and rear. I have read that it is possible to convert to a Saginaw pump, but I am yet to figure out all the details, it appears bracketry is an issue...

I have also read that getting a new PS pump, new not reman, has satisfied many people.

There are upgraded C2 pumps out there that use Saginaw internals, but they cost slightly more than a Saginaw pump...

The hydro master bore is too large to make the drums happy. I file the mounting holes for the original MC and it stops waaaaay better.

Russ, I just sent you a PM on FB before I read this. The hydro bore is too large? Mine is marked at 1 5/16. The vacuum unit it replaced was 1 1/8. Re the mounting holes, do you mean the holes through the firewall? I don't recall having a problem. The 4 studs slid right through and tightened down. Is it possible that I have a poor hydro unit?

I have a post somewhere on the forum on this, I did decently extensive testing on the hydro boost setups for these trucks swapping different steering gears, pumps, etc. The best performing pump which i now run on each of my trucks is the Edelman 6014R designed for the 99-03 F350. Bolts right on and is meant for hydroboost including the extra return.

Gandalf, have you checked to make sure that your rear brake shoes are working correctly? There was a thread a while back about how many of them were cast incorrectly, causing them to only slightly expand and not grab the drum with enough force to provide stopping power. I ask because I swapped to hydroboost and felt a huge difference, I can lock up the tires easily.

Here’s the thread about brake shoes:

The problem with new brake shoes and the parking brake.

Garbage mechanic sent me some pics of the problem with the parking brake and new brake shoes. I'll post them here, along with his comments on them. (I'll put his comments below the pics.) Then he can come in and answer questions, or make further comments, etc. I think I'll post one picture per...

The rear brake adjustment is a good and a valid point. Its something I'll have to check. As nearly as I can tell from my records I adjusted them about 18000 miles ago. Maybe its time to look again. If its a question of not expanding enough to properly grab the drum I should be able to see by the wear pattern on the shoes.

Ive got hydroboost with saginaw pump. Front disc, rear drum steering and brakes work great. Converted my idi to saginaw pump using econoline ps bracket. Couldnt get thre ford pump to quit whining. Even the ford pump ran the steering and brakes really good. that noise is embarrassing

 

[ROCK HARVEY]

Gandalf, a telltale sign for me that my brake shoes had the incorrect casting was that my e-brake was weak and wouldn’t hold on an incline, even though the shoes were adjusted properly. You might want to find a hill to park on and see if the e-brake alone can hold the truck without rolling in neutral.

Something I've read about (I don't have hydroboost) is that if you made the swap but didn't swap in the PEDAL from the HB setup then the pin for the actuator rod will be in the wrong spot. Obviously that's a leverage thing, and some people have the same problems and change the pin and viola, all is good again.
It's moddable, not something that requires the actual pedal to do, but can drill a new spot for it.

Write-up on how to move the pedal pin
