Another question on the NT 254 hydraulics. Mine has a steel
line pointing to the rear of the machine and dead ends with a
quick-disconnect, apearently to supply hyd. power to pull
type implements and other uses. There is nothing in my
owners manual about this or how it works but I may want to
use it someday. There is no return line like I have seen and
used on other tractors. Is this a power up, gravity down
port, or do I need to install a return line to the tank? Does the
selector knob below the front seat need adjusted to supply
power to this? What lever is used?
Thanks, Smokey
I had a little air getting into my system near the hydraulic
screen (filter). I pulled the screen out to check it and noticed
the stem was not screwed up tight against the O ring on the
cap. This screen is located under the left side of the seat. If
you follow the suction line from your hydraulic pump to
under the seat, you see the line attached to a cap with 3
bolts on top of your hydraulic tank. Your screen is under
this cap. Anyway, tightening the stem up took care of my
problem. Smokey
Grumpy, Ron, got fittings today, steering and everything works
now after connecting power beyond to the diverter. I stuck a
temporary hose from the FEL return port back to the tank to try
things out. I was suprised nothing came out of the hose during
normal loader & 3 point functions until the relief valve kicked
in and bypassed oil when reaching the end of a cylinder.
The loader is a lot faster now. My adjustable relief valve
cartridge from Cross is back ordered for a couple weeks, so
when I get that I will be ready to rumble.
Thanks for your help guys, you are my hero's.

Ok, Thanks guys. Looks like I need to change a hose end and
may need another fitting or 2. Will work on that next week
and get back to you. Thanks, Smokey
RonJ, sorry but I have not figured out how to print out a full
size copy of your pictures to study, so I will try to bounce back
and forth between your pictures, this post, and my memory.
Presently, I am connected exactly as your pictures with the
following exceptions. My line D, the 3 pt power supply, was
apparently changed to a hose with quick disconnects when
the FEL was installed. I have a power beyond port on the back
side of my FEL control valve, that you do not have pictured.
So, line D out of the diverter valve previously was connected to
the pressure side of the FEL control, and the power beyond
port was connected to line D for power to the 3 point. These
line were all equipped with quick disconnects so when the FEL
was removed from the tractor, line D was coupled to line D
for power to the 3 point.
I now have the power beyond connected to the 3 point supply
and have nothing connected to line D out of the divert valve.
After sleeping on this overnight, I think I need to connect
line D from divert valve to line D 3 point power supply, and
run the power beyond into a return line.
Your response would be appreciated, Thanks, Smokey
Got all the Fittings today, put er together, purged the air out
and cranked er up. The loader works a lot faster now, a gerat
improvement. Thought I would take her for a spin. But OOPS,
no power steering ! After all the re-plumbing, I have one hose
left about a foot long coming off the left side of the diverter
valve that is not connected to anything. I has a quick coupler
on it. This hose previously provided pressure to the FEL. I
will call this port (4) of the diverter valve.
So here is a rundown of how I have hoses connected.
The first hose goes from the hyd pump to the FEL pressure
port. The FEL return hose is connected to the front inlet of
the diverter. (port 1) There are 2 other ports on top of the
diverter. The front hose (port 2) connects to the steel return
line on the left side of the tractor. The rear inside hose
(port 3) goes to the power steering box. The steering box
has 3 other hoses, 2 to the cyl. and 1 return to the steel line.
I did not mess with these. The FEL power beyond hose
was connected to the 3 point line and works good.
Any ideas, Grumpy? Anyone? Thanks, Smokey
Grumpy, you were right about the power beyond port on the
Cross FEL valve, It needs to be connected. I called Cross Mfg.
today and a gal named Linda verified this. Funny thing, Cross
Mfg is in Lewis, Ks, only 50 miles from me, I am in Dodge
City. She had some good news for me, Cross makes an
adjustable relief valve cartridge that will replace the 1300 psi
relief I have in the SS valve assembly. The part # is 1R0135,
and is adjustable from 1500 to 3000 psi.
I am still waiting on metric fittings, will not be here til next
week. Smokey
Thanks for the warning, Grumpy. I am still waiting on
fittings so maybe someone will post more info on this.
I kinda thought fluid would go through the return hose
next to the pressure hose when the FEL is idle. Will
find out before I crank her up.
Thanks, Smokey
Grumpy, RonJ,
Tore into the project yesterday, had to order a couple of metric
fittings from local IBT store to tie into Hyd. pump & Div. valve.
Looks like I need to place quick couplers on these hoses in case
I remove the loader from the tractor, so they can be connected
together. It appears I can do away with the power beyond hose
since I have quick couplers between the diverter valve and 3 PT
feed that were previously used with the loader removed.
Is it OK to plug this off on the Cross loader control valve?
Also looks like I can omit the return hose from the FEL valve
to the steel return line on the left side of tractor, since there
is an existing return line from the diverter valve that goes to
the same steel line back to tank. I would like to clean this up
a bit, all these fittings are around the fuel sediment bulb
which makes the bulb almost impossible to remove.
Thanks for your comments. Smokey
Grumpy, RonJ,
The FEL control valve Grumpy illustrated looks exactly like mine
with casting # 4Z4110 and relief plug reads 1300 (7Z) (H07).
Discounting the 4 loader control houses on the valve, I have
3 other hoses. The lower front hose is pressure from the
diverter, The upper front hose is a return to left side of tractor
to the tank return pipe. There is another return hose on the
back of the FEL valve that goes to the tank return on the
right side.
My diverter valve looks like the same as Ron has illustrated.
I will get back to Ron on the plumbing I have after I study
it a little more. Thanks, Smokey
