Line B comes back from the power beyond port on the loader control valve. It flows constantly when the tractor runs which it didn’t until I changed the springs in the loader control valve. One was bent. Flows about a gallon a minute at idle. So my further issue is inside my 3 point I think.

I get flow at the supply/return lines at loader the block on the 3 point. The return is about a gallon a minute or so. I’m going to replace the whole power beyond rubber lines and coupler from the loader valve to the block on the 3 point. Seems restricted. Tom

I get like a garden hose on 20% or so. Will shoot about 2-4 inches out of tube then drops to ground. Fill a beer can in about 5 sec

So when I put the lever in lift or any position but the most foreword, if I lift the arms while the tractor is running there is a slight pressure that pushes the lever foreword, I can easily hold it in position. It’s not like it is sticking or being pushed at all mechanically by the rod...

Fluid pressure is pushing on it.

So I got back to the tractor. I have flow to and from the laolder block in the side of the 3 point. Still no movement. But I did notice depending on the position of the lift arms if I lift them by hand the three point lift handle will be pushed foreword by the linkage coming out of my...

So that is the way I have it hooked up. I’m waiting for a coupler to come in so I can loop the green line and eliminate the loader. The quick disconnect is frozen for that one line. The fluid will shoot about 3 feet at idle out of that power beyond elbow on the main loader valve. I was trying...

The line to the IN on the loader valve comes from the block on the side of the 3 point as well as the rear most line marked green on the loader valve which I believe is the return to the block. The line to the rear of the 3 point is connected to the OUT on the loader valve returns oil to the...

Hope these are ok.

The block is definitely sandwiched against the PS feed block I’ll try again to post a picture.

There was a bent spring inside the valve on one of the shuttle valves After replacing with a like spring I get a ton of flow out of the rear port. Which goes back to the block. My loader feed block is on the left side of the 3point housing. Still doesn’t work. Should the rear line be the...

So I get no oil from the out/return back to the loader feed block on the side of the 3 point housing. The rear port on the valve flows slowly which is to the reservoir/trans case. This should only run when the loader is in use. This is all tested with loader at rest. I think the pressure...

I found the schematic. It appears to be plumbed correctly. Can the inner spool of the loader valve fail and cut the flow to the 3 point just like it would if you were using the loader? I noticed that the handle for the 3 point lift is getting pushed away from the lift position with slight...

I am having trouble finding the schematic for which lines they are. I have an LA450s loader with a 7 line valve If i trace the lines it appears the original colors are matched on the lines ?

NO DRAFT OPTION IT'S A 7 LINE VALVE I SWAPPED THE LINES THAT RUN FROM THE LOADER BLOCK ON THE SIDE TO THE 3 POINT TOP COVER AND IT ALMOST STALLS TRACTOR. ONE THING NOTED IS THE LINE TO THE TOP REAR OF THE 3 POINT AREA NEVER GETS FLUID TO IT NORMALLY. A LITTLE WENT THERE WHEN THE BUCKET...

IT'S A 7 LINE VALVE I SWAPPED THE LINES THAT RUN FROM THE LOADER BLOCK ON THE SIDE TO THE 3 POINT TOP COVER AND IT ALMOST STALLS TRACTOR. ONE THING NOTED IS THE LINE TO THE TOP REAR OF THE 3 POINT AREA NEVER GETS FLUID TO IT NORMALLY. A LITTLE WENT THERE WHEN THE BUCKET IS CURLED. I ALSO...

NO REAR HOOKUPS. ALL HYD LINES WERE ORIGIONAL ON EVERYTHING ALSO. IT WAS INOP WHEN I RECEIVED IT.

YES THE LOADER AND STEERING WORK FINE. I FIGURED MAYBE THE LOADER VALVE WAS RESTRICTING THE FLUID TO THE 3 POINT ? SO IF I TAKE IT OUT OF THE LOOP IT WILL ELIMINATE THAT ISSUE IF ITS AT FAULT

ITS AN EARLY 90s L2350. THE LOADER AND STEERING WORK. 3 POINT WAS AS IS WHEN I RECEIVED TRACTOR WHICH SAT FOR A BIT, . THE CLUTCH WAS RUSTED TO THE FLYWHEEL. THE LOADER IS A KUBOTA LOADER. THERE IS NO NOISE CHANGE OR ANY RESISTANCE IN THE ARMS NO MATTER RPM OR THE LEVER POSITION...
