C2 PS Pump Bung Swap??

Bruno2
I am about to change the bung for the high pressure hose. The lines have a different fitting so the new isnt the same as the old. The new one I am putting in requires the O rings. However, the line is the later line that doesnt use them.

Are there any magic seals or O rings to deal with when removing the bung from the C2? Do they just seal when tightened  and I don't need to be on the lookout for something necessary that needs to be installed like a stuck on seal thst needs to be found and removed?

According to this diagram Steve83 posted in another thread it appears as though the teflon seals actually seal the bung to the pump and not the hose to the bung?

Brandon, I have pictures of the C2 bung removed and side by side with a Saginaw bung over on FTE.

What is a 'later hose'?
Are you adapting something from an OBS to a Bullnose?

A little more context would help answer the question.

And a Bullnose hose won't fit the OBS steering box?

I understand you're trying to use the OBS hose, but a pressure line for a Bullnose is only like $12 and most places have one on the shelf.

Ask them to pull one for an '85 and one for a '95 and compare the hard ends at the box.
It really could be that easy.

The steering box end didn't change, when I needed one for Darth, we had a perfect 1996 box from a flipped F150, I installed it using my old hoses. When I was getting ready for the EFI conversion, I used the donor truck's (1990 F250) C2 pump, which takes the newer hose, I used the hose from the 1990 into my then still 1986 steering box. Get a hose for a 1986 with the same engine, 351 if I remember correctly.

The newer hose isn't going to fit the older bung.

A new hose in the old Bullnose style is only $12 and likely on the shelf of your LAP.
Sometimes the only reasonable path is through your wallet.

Above we have an OBS C2 pump on the left and a bullnose C2 pump on the right.



Here is a shot of the high pressure bungs that adapt the high pressure hose to the C2. The hose fittings themselves are a different style. The bullnose has an O ring around a tube that goes into the bung where the OBS fitting looks more like a JIC and uses a thin teflon O ring around the top of the flare nut to seal it.



Here is a shot of a Bullnose C2 I had out at the shop(this one is Jr's) with the OBS bung installed as a test run in order to be sure we weren't going to hit a snag when we got off site at Kris's house.

Long story short, the actual bung swap took about 5 minutes . It was a success with no leaks.

In conclusion, the C2's are completely interchangeable . However, remember there is a difference in high pressure hoses.  So be sure you get whatever parts necessary off of the old unit for the install.

Gary, yes. We installed it last weekend and drove it home. He called me saying there was a trail of hydraulic fluid in the driveway along with the pump whining when he arrived home.

Keep in mind I was letting him do the work. I was simply showing him what needed to be done and how to go about it. I never saw the hose end in his truck. I used the bullnose hose to see if it would thread into the OBS pump when he had it removed. It threaded in nice and snug like it was made to be there.  It didnt throw a flag to me because of all the different types of fittings there are in the high pressure hose world (SAE, JIC, flare, compression , NPT, O ring boss , etc,etc) hardly any of them use the same thread pitch. It fit like a champ so I considered for us to be in the driver's seat.  When he informed me it wasn't sealed I knew something wasnt uo to snuff and I began the inquiry.

He will learn.  And glad you got it sorted.  

By the way, have you seen that I'm looking for an '86 - '97 4wd F350 w/a 460 or diesel?  I need the cross member, which only the 460/diesel trucks had, and would like the D60 front axle and suspension.  Know of any wrecked ones or w/o an engine?

I didn't know you were looking for such. Those D 60's maybe hard to come by. Yhat is the desired axle to do a SAS . People put them in Broncos along with anything that came with a TTB.

Big Blue's engine cross member has been sawz-all'd.  It is toast and has to be replaced.  So, while I'm doing that the guys have suggested that I replace the F250 teeth-jarring suspension with the F350's.  Given that, if I can find a truck with everything it shouldn't be terribly expensive.  Still have to find the cross member even if I can't find the front axle and suspension.
