Morning Everybody.

My steering box is leaking at the high pressure port. I've re-seated the high pressure hose several times with no luck. I was surfing and came across a picture of the steering box showing the two ports and it looks like there are o-rings in there. Can anyone confirm that there are or are not supposed to be o-rings there? I know there isn't one in there now.....


Thanks.

No, those aren't o-rings.
What you have there are replaceable brass tapered seats. They are a light press fit and can be pulled out and replaced.
I'll see if I can get the P/N for you. The two are different.

 

It would make sense then that if the taper of the new hose's fitting didn't match to the taper of the existing seat, I could have leaking.

Thanks for the response.

 

The part numbers for the seats are:
5/16" tube (high pressure, this is the one you need) 374309-S
3/8" tube (return) 374480-S
374309-S:
Mid-Tennessee Ford Truck, Nashville, TN has 1 (615) 259-2050
Larry H miller Parts Warehouse, Salt Lake City, UT has 3 (801) 488-1700
374480-S:
Dennis Carpenter Ford, Concord, NC has 4 (704) 786-8139
Green Sales, Cincinnati, OH has 72 (800) 543-4959

They're relatively easy to replace. Get a tap that will fit in the hole. Pack the flutes with grease to keep metal shavings out of the gear as much as possible. Tap the hole. Get a screw that's the same size as the tap you used, a nut to go with it and some flat washers.
Screw the nut onto the screw, place the flat washers over the port on the steering box, screw the screw into the port. Tihjten the nut down onto the flat washers to pull the old seat out.
Gently tap the new seat in to get it started, then install the hose and tighten it down to seat the insert.

 

Usually what happens is either there's now a groove in the seat from wear or the seat will have a nick in it or some other damage.

 

I see you helped out on a similar issue on a thread back in '17. 'Steering box leak'. Looks like I'll be adding this to my 'Things to Fix' whiteboard - and I had it down to 3....

Really appreciate the help.

 

No problem.
Just a note, your white board list will never get to "0"

OOPS! Good catch. Thanks Bill.
I corrected the post.

 

I deleted my post....

 

Didn't need to do that Bill, if I make a mistake, I make a mistake.
What is it they used to say?
Mistakes, lawyers appeal theirs, doctors bury theirs, but newspaper's mistakes are in print...forever.
Of course, that doesn't matter anymore .
