Ford 2810 hydraulics

Hydraulics are weak on both Rhino front end loader and 3 point lift.

Photobucket

Very slow to raise the hay forks both front and back.

Both were slow even before adding valve.

Photobucket

No down pressure on the front end loader to raise wheels off the ground.

Is there any way to increase the hydraulic pressure?

I'd stick a gauge in the remote and see what kind of pressure it makes at idle with hot oil. Should be 2500. If it's somewhat slack that would suggest a poor pump. If it's WAY down then I'd be looking at the releif, flow control or a blown o-ring somewhere.

I'd also guess that those bales are probably a good percentage of what that tractor is rated to lift both on the three point and certainly on that loader.

How quickly does it lift with no load relative to when it's loaded?

It lifts slow both loaded and unloaded.

Didn't really notice the slow lift until there was no downward pressure to raise the front wheels.

Use the downward pressure to mash/compact limbs on the burn pile and also to lift the front end to change/repair the monthly front flat tire.

If you remove that diverter plate you have under the remote valves.... and reinstall the remote valve.... how does the three point behave then?
Is that diverter actually a controlled valve with a knob you move to supply the loader or is it just a plate with one line?

Normally the problem you describe would lead me directly to the system flow control near your right ankle... but I've got some questions about how that diverter plate works...

The diverter valve is just a plate with one line for the front end loader.

Stopped by the Conroy Tractor (New Holland Dealership) in Mt. Pleasant, TX this morning and spoke with the owner Joel Conroy.

He showed me the system flow control on a similar tractor.

He said it should be marked and to turn it counter-clockwise to increase the speed.

This is how the system control flow was set.

Photobucket

Turned it counter-clockwise to the new setting.

Photobucket

This increased the "speed" of both the front end loader and the 3 point lift.

Still do not have any down pressure on the front end loader.

Made arrangements with Mr. Conroy to bring the tractor in next week.

Thanks for you help; I certainly appreciate it.

If the loader otherwise has good lifting power I would suspect you have a float spool or something similar that doesn't provide downpressure on the loader.... unless it's a case where it tries to provide some down pressure but can't quite lift the front end.

That diverter plate looks like the one on my 4610 under the dual remotes(non-deluxe). It provided hydraulic flow to the loader valves and does not have a separate valve on it.

Quoting Removed, click Modern View to seeBut & it is a big BUT......pressure alone doesn't tell you much. It will only be proportional to load being lifted. Light load=low pressure. Chain the arms where they can't rise=overpressure relief pressure or pump limit.

Could your problem with no down pressure be caused by the valve being in single action mode. At one time I had a Ford with a similar control valve as yours. There is a hex head set screw in the front of the valve body that is turned out for single operation, in for double action. I believe that screw is visible just below the valve spool in the front.

Make that an allen head screw. Joe

I agree 6B. Put a gauge on it. Just as you can't read what your electrics are doing without a VOM you can't see hyd pressure without a gauge.

The flow rate and cylinder volumes control the speed of the lift and the pressure, piston area and loader geometry determine the loader lift forces.
How heavy are those bales? You might be cracking the relief valve open with that load on that small a tractor or you may have an internal leak on the three point lift cylinder or have a partially stuck open relief valve and there"s not much flow available for the loader.

I have a Ford 4610 with an EzeeOn loader and it slow because I"m using the internal pump only. That pump is like a 6.5 gpm pump and you won"t get much speed out of that flowrate esecially with the big curl cylinders that I have. Your 2810 is even smaller than the 4610. You just might be asking for a little too much out of that pump. if you want more speed, you"ll require a bigger pump or if there is a 2nd pump option on the 2810( there is on our 4610) you might consider than. As far as the down force problem, you may a have a an internal system leak that that"s reducing the pump output pressure or the pump is worn. Since you can"t lift the front wheel up, I think that"s the problem. I don"t believe the relief valve is adjustable on these models.

"No down pressure on the front end loader to raise wheels off the ground." Why not? Looks like double acting lift cylinders?

"Is there any way to increase the hydraulic pressure?" Pressure is a result of a pump working against a restriction. If you had a 4gpm pump trying to operate a lift cylinder with a 4gpm leaking seal, no pressure would develop. Leaks can be anywhere, even in a worn out pump. Outside of leaks, there is the overpressure valve (still a 'leak' of sorts).......sometimes trash between ball & seat, maybe weak spring, eroded seat, etc. Have you measured the pressure to know that it is below spec? If not & lift just doesn't do all you want it to do, you may be asking more of it than it is capable.
