L4400 fel not working

[bsamot69]

Thats why we are going through the circuit inch by inch.

We now have verified outflow at both workports. Next up - the cylinders

Reconnect the ends on the two quick coupler hoses.

Go to the lift cylinder on the right frame and disconnect both hoses. Put them in your bucket and repeat the last test. You should get alternating flow as you move the lever from up to down. Watch yor fingers in case the loader decides to move.

If you get flow reconnect the hoses and go to the he left side cylinder and repeat that same test.

Okay, I'll pick it up in morning. I have more time now that we're done baling hay.

Got a late start today.. both the left and right lift have alternating fluid flow

Reconnect all cylinder hoses. Then verify connection as follows.

1. Disconnect hose on BASE END of right cylinder. Let me repear - BASE .END, Now move lever to raise, and confirm you get oil fkow.
2. If you get flow reconnect the base end hose.
3. If no oil flow swap base and rod end hose connections on that cylinder.
4. Repeat steps (1-3) on left side.

Test loader lift.

Test loader lift.

Oil flows from cylinder both sides.

I have no idea what you have done. If you followed the instrctions above sll ports and hoses should be connected. Post pictures of left and right cylinders and hoses.

Really, that is what is happening. What was supposed to happen?
This is the setup we have been working with since post 106..
The power beyond is in filler hole, the tank line is in bucket. The 2 quick disconnects on left side of loader valve are disconnected. And when I disconnected hoses at the base of cylinder, ran the tractor, moved stuck to Raise lift the fluid came out of cylinder..

That is not what post 123 said to do.
Everything is right up to the cylinder part. Show me pictures of the cylinders and hoses. Where is oil coming out?

Okay, I will reconnect the tank line to loader valve, take power beyond out of oil filler and connect it. I have connected the cylinder hoses. The only disconnected hoses are the quick disconnect going to bucket.
I will redo the tests we did this morning again. In my defense, I did ask you if I should leave the tank line in bucket and pb line in oil filler .
I'll get you pics when I get back to shop .

No, no, no!! Leave PB and tank alone

All I want you to do is test things at the cylinder. I dont understand what you did there. Post picrures of cylinders on both sides.

Picture of right cylinder base hose disconnected. Fluid came out of the hose when lift raised. Plus pictures of both cylinders.
Tested left cylinder same way and fluid came out hose

I assume the loader is hooked to sn overhead crane.

Lower the loader, connect both base hoses, start tractor, and move joystick to raise. It should go up.

[bsamot69]

Actually the loader is resting on forks. I connected the hoses to cylinders started tractor. Loader does not raise

Try to raise again and this time watch the tank return.line. Do you get oil from the tank line when joystick is operated?

I start tractor and fluid comes out of tank line immediately.
When I raise loader more fluid comes out tank line. Loader does not raise

I thought we determined that with tractor running and loader valve in neutral there was no fluid from tank line many posts back.

You have one hose in the filler and one in a bucket. With tractor running is there oil coming out of none, one, or both?

 

[Russell King]

I am so confused by the replies.

1) How is it possible for fluid to be coming out of the tank return line with the tractor running AND the valve in a neutral position?

The one in bucket has fluid coming out in neutral and stream increases when in raise position.
The fluid coming out in neutral I don't remember seeing before. Maybe I EFFed up before but this is what is happening now.

Multiple ways but I thought we were past that point. This thread is full of confusion and miscommunication. Until we get the actual facts on the ground established I wont confuse things even more.


Right now all I want is an unambiguos answer to my question in post #135

The unambigous answer is ...the line in oil filler....the line in bucket from tank on loader valve,
Tractor in neutral oil flows from hose in bucket.
I move joystick to raise and pressure increases coming out of hose in bucket
The loader does not raise .
