Ford 5600 Power Steering Problems

On my Ford 5600, several o-rings and the top seal in my power steering was seeping. After completely disassembling and replacing with an aftermarket seal kit, everything works great and there are no leaking seals.

Now there is a seep at the bottom of the main casting at something that looks like a freeze plug. There is a reference in the repair manual of this being a “locating peg”.

After all the work of completely removing and rebuilding this assembly this leak is discouraging. Has anyone experienced this or know how to repair this leak?
 
Bad news: You need to take it back apart, all the way. It pretty much needs to come completely apart, because the piston has to come out to remove that peg. This also means the rocker-shaft needs to come out, which requires you to remove the steering arm (potentially not fun). That locating peg comes out from the inside, and has an o-ring on it that you need to replace.

I've seen people try and silicone around the outside, but it's a futile effort. I doubt JB Weld would work here either, because it's under pressure. There's only one way to fix that leak, and that is to take it all apart.

I was afraid of that. However, it is good news that there is an o-ring that seals that peg. Sure wish the repair manual had mentioned that. I was so concerned about getting all those balls to fit back in the correct location I suppose I overlooked the peg being removable.

It is a pretty big job to fix but it will be worth it to not get hyd oil on my pants and shoes every time I use it.

Thanks for the information.

It actually IS mentioned in the repair manual, step #3 to be exact. Don't forget step 1 #1 either.

Bern, Now that you point that out, I see it in my book too. Never noticed it before.

If the step 1 # 1 is important, could you tell me what it references? My book is slightly different than yours.

Thanks, John
 
The book I'm using is the Ford factory manual for a 7000, but the box is identical. Reference #1 refers to the two o-rings at the end of the box on the LH side, where the steering shaft pokes through. If you have to go as far as that locating peg, you'd be foolish to not replace those two o-rings also, since they're right there. They are reference #43 in the attached picture. O-ring #14 is one that a lot of people forget also. Did you do that one?

Fortunately, I did replace the two o-rings where the steering shaft pokes through. I am not positive I replaced the #14 ring.

I hope to remove the rocker shaft and then pull the column complete with the piston to get to the locating peg and replace that o-ring without a complete disassembly.

Is there any reason that will not work?

I've never tried it that way, because I've never had to, but after thinking about it for a bit, I can't see why it wouldn't work. Of course, if you didn't replace #14 o-ring, you might wish to consider it while you're that close and take it all apart anyway.

I think you'd remember doing #14 o-ring if you did it (see red arrow). The plug that the o-ring sits on does not usually come out without a fight, as there's nothing to grab it with. I get it out by blowing compressed air against it.
