5610 Hydraulics

yankeeredneck · Apr 27, 2014

I recently purchased a Ford 5610 4x4 with a 777 loader. It has a single hyd pump, two remotes on rear(one runs the loader). These remotes are run by valves located by the 3 point control. After mounting my hydraulic winch I'm having trouble getting enough speed or power to run it. I had this winch on a 4000 that had a front pump, I think was 11-13 GPM. So I realize that the hyd on the 5610 are going to be considerably slower, but it is extremely slow and has probably half the power. I have the winch plugged in to the other rear remote, which is in itself another issue. You have to shut off the loader valve in order to operate the winch and vice versa. I tried running the winch from the (out) side of the loader valve located on the loader frame to the winch valve and then back to the remote. That was a little slower yet. I'm no ace mechanic by any means, but am I missing something here? The loader is also verrry slow, haven't really tried the 3 point as the winch is mounted solid in the up position. Any help would sure be appreciated.

Welcome to Ford's CCLS hyd system. I once owned a 5610 and the CCLS (closed center load sensing) remotes gave me all kinds of grief. For my use I'll take Ford's straight open center hyd's over CCLS. I sure some hyd knowledgeable person will come to your rescue.
4000

Which tractor are you installing the winch on and what type is the hyd.

What kind of valve is on the winch?

The speed of the winch will be related to the GPM supplied.

You have 62 HP at the PTO.

If you have to, you can go to a PTO pump and supply lots of fluid to the winch.

How much flow do you have?

Here is 22 GPM at 2000 psi.

9.9 CU IN PRINCE HC-PTO-1AC PTO PUMP CI 540 RPM

Thanks for the input, can someone out there explain( closed center load sensing) hydraulics? Is there some way around this without adding another hydraulic system? Thanks

CCLS

Read through this.

Very simply stated, it is a hydraulic
system that senses and provides only
the pressure and flow required by the
hydraulic system.
The components required to accomplish
the characteristics of the load
sensing system are: A variable volume
piston pump, that has a compensator
that will allow the pump to standby at
low pressure (200 PSI) when the
system is not being actuated. It will
sense the flow requirements of the
system when it is being actuated and
provide a variable flow rate as the flow
demands of the hydraulic system are
varied. The pump must also sense and
respond to the varying pressure
requirements of the hydraulic system.
Most hydraulic systems do not operate
at constant pressure. The hydraulic
pressure will vary as the load on the
hydraulic system changes.
A control valve, with special sensor
passages and checks, is also required
to get the full benefit of the load
sensing system. When the hydraulic
system is not being operated, and is in
the standby mode, the control valve
must cut off the pressure signal from
the actuating cylinder (or motor) to the
pump. This causes the pump to
automatically go into low pressure
standby when the system is not being
operated. When the control valve is
actuated, the control valve will pick up
the pressure requirement from the
actuating cylinder (or motor) and send
that pressure signal back to the pump
where the pump starts to respond to
the system pressure. The flow
requirement of the system is dictated
by the movement of the spool. The
system flow requirement is sent back
to the pump, through the signal line,
from the control valve. This combination
of a load sensing pump and load
sensing control valve allows the total
system to provide only the flow and
pressure required by the load sensing
system.

You'll find the load sensing valve on your 5610 is located on the frt top of rockshaft housing. This valve housing has a little shuttle valve contained in it. My 5610 had a cab which made this valve difficult to access when it required servicing. There's a small sensing line from the valve to the rear remotes. My 5610 had difficulty in getting oil to flow through the remote breakaway's.
