Help! Exhausted my ideas!
 

I posted the 125 with loader opportunity forum. I love my tractor and the tiller and the loader but... The loader will not lift? I have good cylinders and lines and the pump turns. I even took the pump apart and it looks fine. Valve is fine and i blew air threw to clean any obstructions out. I c no reason why it doesn't work? Wen i push down on valve ir has suction in the line witch means down works but it doesn't seem to get pressure to lift? Idk wat to do? Any help would b spectacular! Even if i need to buy a pump were at? At a loss...😓

Does it have oil in it?

You sure it is plumbed correctly?

You sure the pump is attached correctly and rotating the right direction?

What do you mean it has suction on the line?

You need to give far more information.

Ok. Yes it has fluid i put new in. Plumed? And yes it turns the right way. By suction i mean wen i took a line off to bleed it i put my finger over the line and wen i pushed the lever down i felt suction as if it was lowering

I m new at the cubs but im a hand on guy and can do a lil everything. I do love my cub but im just frustrated because i m going to use my loader on my farm and its just not working. Again im new so plz n e help is help

Alright let me get this off my chest. According to your profile, your 24. Please proofread your posts. You can surely spell "when" and "please" the right way, and know how to type. I won't sit here and try to figure out what your trying to say. This isn't texting, it's a forum.


1.) DO NOT EVER put your hand over a hydraulic hose if the pump is on. Good way to shoot oil under your skin. You can die from this. NO JOKE.

2.) Do not remove hoses to "bleed" them. You shouldn't need to bleed anything other than maybe the pump, and that's only if the pump is above the tank, or it is air locked. It should self prime and self bleed.

3.) Plumb. As in plumbing, plumber... A reference to the hydraulic hoses being hooked up right. Are they hooked up correctly? If you say yes, how do you know for sure?

4.) Relief valve. Does it have one? Is it working?


You likely will have to post some pics.... Right now, you still have given me nothing to work with.

Sorry i do text alot I'll remember that. I appreciate your honesty. It is hooked up right because on the pump it has in and out stamped on it. And on the valve it has in and out stamped on it. I didn't know about fluid under the skin so thanks again. I am not sure on a relief valve I'll get pics for you.

One thing about this forum, pictures really help a lot! If its a common problem sometimes they are not needed as the solution is just a cookie cutter answer. Stuff that has to be figured out, well the old saying about a picture is worth a 1,000 words speaks for itself. :beerchug:

Posting pictures on here is weird. Ill try to get better pictures in the morning.

PTO isn't slipping when you load the pump is it? Try to lift the loader and watch the pump shaft. Does it stop spinning? Does this tractor still have a PTO on it? Or has it been removed and replaced with a pulley?

Like John said, pics do help a lot. More please!

Yes the pto is still on. I read another guy had the same problem and he said the OUT on the pump should go to the IN on the lever. And the OUT on the lever goes to the cylinders. And the other port on the lever goes to the IN on the pump. Mine right now is in to in and out to out. So I'm ganna try that when I get home

you have it plumbed WRONG!! "OUT" on pump goes to "IN" on control valve. "OUT" on control valve goes to hydraulic oil tank and from tank to "IN" on pump. the other ports on valve go to the hydraulic cylinders

I believe you guys have it figured out, out on one thing goes to the in on the next thing.

Kinda like extension cords, you don't put two like ends together.

I get that now. When i bought it from some guy that had 3 loaders and like 50 cubs this is how it was. But it makes sense now

I hope it works as intended when the plumbing is fixed. And I hope you post some video of that loader in motion! :IH Trusted Hand: :beerchug:

And...... there it is.


Glad you figured it out. :beerchug:

Ok getting mad... I have a 1800 psi cessna pump for a danco loader. I put the OUT on pump to IN on valve. Then the OUT on valve to the cylinders and the other port on the valve to the IN on the pump. It spins the correct way to pump and... Nothing? I don't know what to try next.

I think your still doing it wrong. The valve should have 4 ports. IN, OUT and two for the cylinders. Unless they are only 1 way cylinders.

Pump OUT to IN on valve.
OUT on Valve to IN on pump.
Other two lines to the cylinders. One hose should "T" and run to the bottom of the cylinders, the other should "T" and run to the top of the cylinders.

Is only a 3 way valve. Has an in an out and one not labeled. Someone else told me out in pump to in on valve. Valve out to cylinders and the other port on the valve not labeled to in on pump

Sorry and yes they are only one way cylinders. Has up and gravity down

No.
The one not labeled goes to the cylinders. I didn't know if it had one-way cylinders on it or not.

Ok did that... Still nothing... I wonder if it's spinning the wrong way? I know someone said that already and i looked and the arrow points towards the"driver" side and it looks like it spins towards the "passenger side" from the pto pully. Id that's how it is how do i switch that?

Ok... listen, when I ask a question, and you answer it... Such as when I asked if the pump was spinning the right way, don't say "YES" unless your sure that the answer is yes. If you don't know, say "I don't know", then ask how you can tell. Your making this more complicated by giving a "false" answer. We're on post #29 and haven't really established anything yet for sure other than it doesn't work.


Is the shaft on the pump rotating in the direction of the arrow on the pump when it is running? If yes, it's spinning the right way. If no, then you have the wrong pump. You cannot reverse it's direction since it has a relief valve built into it. I really doubt that it is spinning the wrong direction, even if it came off another GT that wasn't a Cub Cadet, all GT engines turn the same direction.

Your missing something, or the pump is junk. The most likely answer is: both.

Give your answers in shaft rotation as if you were sitting in the seat. As you sit in the seat, the engine turns clockwise.

Ok the arrow on the pump shows turning counter clock wise or "left" when on the seat

But i guess thinking about it if the arrow points "left" them that would be clockwise not counter clock wise. Check out "danco loader troubles" on this forum and that's exactly what I have

:bigthink:

Is there a solution in that thread?

I don't need to look it up....

He has more specific information on the pump and loader. And I'm sorry i understand that e have gotten no were. Again im new to this and honestly just feel stupid because i can't figure it out. It does spin clockwise. And i would think the pump world's properly because wen the motor is off and i manually them the pully in the correct direction it pushes fluid out of the OUT port on the pump.

How fast are you running the engine when you try the loader?

Mostly at an idle because i don't want to ruin it. But i have sped it up to about half but no faster then that.

Does it even try to move?

No not at all

Well... so, we are fairly certain that you have it hooked up right, and the pump is turning the right way. Next step would be to test pump output pressure. How many psi it makes will help narrow down the issue. This pump does have a pressure regulator valve in it.

I am not sure if it has a regulator in our or not? It is 1800 psi output. Our supose to be any way. So how do i test it?

There is a regulator in the pump. Unless someone took it out. If they did, that's why it doesn't work. I doubt 1800psi on that pump. 1000 at best, but it might make 1800. It's basically a power steering pump. It'seems working range is likely 500-800, with a 1500-1800 max. But as old as it is I'd be surprised if it will make 1800.
