power steering box; port ID
« on: March 14, 2010, 03:20:41 AM »
Always had manual steering, so the power steering box is new to me.
Want to connect the lines correctly (pressure and return), but do not have the OEM-lines. Have a custom set-up with industrial lines.
From what I know is that the rearward port (closest to the steering shaft) is the return line (back to the reservoir) and the forward port is the pressure port.
See pic.
Is this correct????

Thanks!

You are correct. The ports are also different sizes

Noticed the different size; return port is 5/8-18 flare, pressure port is 11/16-18 flare.
Have found some flare-to-JIC adapters.

Mine were metric in a mid 80 Rc. I did get the metric adapters to AN from Aeroquip. Look under part # FCM2608 & FCM2609.

Suppose you have the standard rotation with the output shaft vertically?
I have the reverse rotation with the horizontal output shaft. Got the original '77 box (remanufactured). These have the flare-ports.
My box is on the 90 degree support, just like the manual steering box.

1979 and earlier use standard inverted flare fittings. 1980 and later use metric "O" ring fittings.

I was looking on rockauto and their pictures and applications listing is confusing me. They list a standard rotation and a reverse rotation steering boxes for 4WD in the same model years.  Am I correct on the assumption that all of the boxes with the steering output shaft horizontally and facing the tire are the reverse type and have non metric hose connections?

You are correct. 1977 may have been a change over year that is why they list both boxes. Reverse rotation boxes have standard fittings, inverted flare and not metric. Metric started in 1980 and use "O" rings to seal the tube.

A tad bit more information on the steering boxes.  I bought one from a member on here that was believed to have been from a 1975 W150 with the 440 engine.  The input shaft splines outside diameter measured .800"-.805" which are the 13/16"-36 instead of the more common 3/4"-36.

18MM o-ring, to be more precise :) (just hooked mine up yesterday)

Are you sure those threads are not 16x1.5mm? (I mean the smaller one) Other one being 18x1.5mm :)

Avoid replacing any part that you have not proven to be faulty through extensive testing.

It is quite possible. I mispoke. Both fittings take the same wrench to install- 18mm.

Let's get a little more technical.

Can I use a metric flare to AN fitting and mate that to JIC -6 fitting? Or does AN have to be mated to AN? Both are 37 just one is steel and one is aluminum, just wondering if AN is directly compatible with JIC or is there something else I am missing?

For the low side, I could care less what fitting is used as there should not be any significant pressure on the return unless something is pinched or clogged.

Never mind, I answered my own question for $7 already. No need to potentially strip an aluminum thread, and cheap heavy duty hose already available. {cool}

You just answered it yourself, but AN = JIC. Army/Navy just adopted the JIC as their standard and re-named it AN.
JIC is much cheaper than AN and available everywhere.
