I have a Ross power steering box that came with my bus when I bought it. It was hidden in one of the bays.
It is an HFB70 type.
Does anyone have information on what is requried for installation on a Eagle 01?
What type of pump, steering shaft/wheel etc. is needed.
Would this be an acceptable box to install?
I really want to get rid of the Armstrong steering if at all possible. ;D
Thanks in advance,
Paul
PS Just got word that Dallas suggested a Vickers VTM-42 pump...Thanks
Hammer, welder, cutt'n torch, welder, bigger hammer, more cutt'n torch, BIGGER HAMMER, OOPPPS MORE WELDING! Yup it'll work! LOL!
Jest jidd'n! I really don't have a clue Paul. But I just thought I'd point out with the right attitude, and persistance anything is possible! And almost any pwr steering is better than no pwr steering! ;D BK ;D

I just changed some seals in mine and in looking it up I believe that that is just a casting number and not the number used to identify it. there should be some numbers stamped into it up around where the column attaches. should be something like HF54 or HF540. that is what mine is in my Eagle 10. How big a hurry are you in to install it? I may be able to get you the mounts out of one that is being scrapped. also change the seals before you stick it in. try this site and it will help you ID it and for any parts you may need. www.prosteering.com (http://www.prosteering.com)

BK,
I figured that I could always count on you for some advice....... ;D
Steve,
The number that is in the pictures says it is an HFB70, that's the way I understood to read it from doing some research. Is that not correct?
Edit~I did check the stamped numbers, it says HFB706696. My manual say that as an option, an HF64 was used. Will mine not work? I would assume the mounting holes are differant, but what else? It does look like the steering column shaft is at the other end.
I really am in no big hurry. Just started doing the research and probably by the time I collect the parts it could be next summer! ;)
Thanks for the offer on the mount, let me know when and how much.
Changing the seals is a good point, who knows how long it has been sitting, and that ain't good for them to dry out. :D

Paul,
I once had a serious problem with matching a master cylinder for a Dodge chassis. The one I "needed" was exorbitantly expensive. The parts guy asked me to get the casting number when he deciphered the casting number he found that 8 master cylinders carried that number. The versions were different in the size of the hydraulic fittings machined into it and the bore diameter. That was all there was to it. I selected one that had the correct fitting arrangement but was a 1/16 bigger in diameter. I noticed that 1/16 difference in pedal pressure. That was long ago and I recently learned that my boosters were both bad and that might have played. I find it difficult to believe that nobody here can clue you to the P/N for the unit but know that you can sleuth it from the casting number...probably.
HTH

Paul, yes there is an hbf70 series but there is a stamped number that will tell you what version it is. the casting number is used for that series but many versions. I would assume that it will work but in looking at the picture of it on prosteering.com it is completely different than my HF54 which was used in most model 10s. you would have to figure the mount out and see if you can still plumb it etc. if all else fails the 10 that is getting scrapped I believe is power with an HF54 box.

This MAY help. (or not) My 1974 Crown had the heavy 16K front axle with the Ross/TRW power assist steering. The pump was a Victors (Victers?) VT42 right hand twin belt driven. Very common.
Two mechanics told me that the pump MAY not be big enough for the power steering. Had some operation/howling issues. Don't know if it had to do with the big axle, long lines, bubbles or the Ross model.
It is possible the prior owner just hung whatever pump he had on the Crown in order to sell it and I had the wrong pump mounted. The required pump may be a bigger/larger model. We aren't sure.
The local hydralic supply store had abut 6 VT42 pumps on the shelves in various configerations. A rebuilt for me cost $350 with a year guarantee. They also made up new oil hoses. Hope this helps. ;) :) :)
I am not sure if my idea of installing this HFB70 will work or not.
I was told that Eagles used an HF64 with 1/4" free play in the steering gear. Which made the coach a little harder to handle. He suggested an HFB64, which has zero free play.
I will continue the research because I need to find out more about the HFB70 statistics.
Thanks Guys, all great information so far!
Between brakes and power steering my brain is saying "Too much information". ;D
