Besides working on the 850 this weekend I tapped the hydraulic port on the 8N. It came together with help from TOH(finding a fitting for the test port), a custom-fabbed hose, & a bracket I made from a piece of angle iron.

This will work along w/ the pick-up hitch(I built last year)to dump the tipping trailer(I haven't finished yet).

Where did you find a fitting for the test port?

Does your fitting connect direct to the hose, or does the hose thread into the fitting?

I would like to connect a pressure gauge to mine, but I can�t find a fitting for the hole.

The test port is a "almost" standard SAE o-ring port (dash size: -5). The port thread is 1/2"-20 which is a standard but not very widely used ORB port size. The "almost" part is because the N test port doesn't have the SAE specified chamfer for the o-ring seat. How-some-ever (as Dell says ;-) the ORB fitting will seal quite nicely if you do not overtighten the fitting/jam nut. If you're sphincterly challenged (as Dell says ;-) you could probably install a copper retaining washer sized to match the thickness and OD of the o-ring and produce a ba$tard ISO-style fitting from the ORB which would seal even more securely. Or try your hand at counterboring the test port!!!

SAE ORB fittings in the -5 size and a variety of geometries are stock items from Parker, AeroQuip, and Weatherhead to name a few. If you need help getting one drop me a line - they run $5 to $10 each depending on geometry. USPS is cheap and I don't charge for gas - the Parker store is on my way to work.

They're kinda hard to find. TheOldHokie mailed one to me from his local hydraulic shop. The pump port takes an ORB-5 male fitting(not exactly industry standard). The one Hokie sent me was an elbow w/ JIC-5 on the other end. The rest of my hose was made up for me to order by my local shop.

To more directly answer your question, my setup is a hose w/ separate fitting on each end. JIC-5 female on one end & 3/8"NPT male(to fit the quick-coupler)on the other.

I like the cupholder..my IH had 3 holes drilled in the fender for ??..so I built a cupholder with brackets to fit the existing holes..comes in handy when mowing ;)

As for the comment about the FEL, I was checking into this very situation, only I wanted to run the tractor hydraulics off of the FEL crankshaft pump. After lots of questions, I was told by Zane that a flow control valve is necessary on the line from the pump to the test port in order to regulate the pressure/flow down to a usable amount for the N's hydraulics. In other words, running an external line from the FEL pump into the test port would make your 3-pt go up, but you would have any control and probably couldn't get it to go down!

Jeff;
I have a similar port on
my 9N.
You do know you have to chain down the
3 point lift in order to get an output
from the hydraulic hose. This makes
a coordinated effort with the 3 point
difficult, if not impossible.
For a FEL this is no problem, and if
your FEL seals are tight you just can
raise the lift, uncouple the hose, and
the loader will stay up while you use
the 3 point.

Yes, the lift arms have to be locked to divert pressure to the port. In my case they are locked more "up" by my pick-up hitch(see pic). I'm using this arrangement w/ a dump trailer(I haven't finished yet). The hydraulic coupler hooks up to the trailer's dump cylinder.

OK, now there's something I've always wondered about. My 2N has the identical setup, once used to lift the arm of a sickle mower. Just how do you chain down the 3pt? Lift arms around the axle, or what?

I just got two chains and go around the
axels with a bolt/nut to hold it togeather.
If you do not chain it the lightest side,
FEL or 3 point will go up first followed by the
other. Going down is another mater.

FWIW
Ford actually manufactured a set of "lift-arm-holder-downers"
(for lack of a better term)
I have some literature for a One Armed Loader that shows the mounting requirements for several tractors including an 8N. They even included part numbers for the things. I'm sure they would be exceedingly rare.

Someone on this board posted a drawing of a Ford part designed to prop the lift arms up. Very simple device that pivoted off the pin thru the lift arm yoke. It stayed out of the way when not needed, but just swung down & sat on the top of the axle housing to prop up the lift arms.

It used an hydraulic cylinder to lift the mower? We had a sidemount sickle bar mower on an 8N that used a pulley and cable arrangement attached to the lift arms for that purpose.

yep, i still have the mower with the cylinder intact. It's a massey harris. It came with the farm but I've never used it. Previous owner said it was great for mowing ditches.

My Father-In-Law used two pieces of angle iron, running from the drawbar to the toplink connection, to hold his lift arms down. The angle iron was cut to the length that kept the draw bar at proper height. This way he could use the drawbar and the remote cylinder. He had a bale carrier for big bales that used a remote cylinder to load and unload the bales.

My stay bars that came with the tractor are massive..... made from 1/2" thick bar stock and sch 80 1" pipe. They would likely work and not bend.
