WARNING
Hydraulic fluid escaping under pressure can have enough force to penetrate the skin. Hydraulic fluid may
also infect a minor cut or opening in the skin. If injured by escaping fluid, see a doctor at once. Serious
infection or reaction can result if medical treatment is not given immediately. Make sure all connections are
tight and that hoses and lines are in good condition before applying pressure to the system. Relieve all
pressure before disconnecting the lines or performing other work on the hydraulic system. To find a leak
under pressure use a small piece of cardboard or wood. Never use hands. Failure to comply could result in
death or serious injury.

5. DISTRIBUTION SYSTEMS - PRIMARY HYDRAULIC POWER SYSTEM
Hydraulic pump - Dynamic description
T8010, T8020, T8030, T8040, T8050
The tractor uses three hydraulic pumps which are driven through a drive housing on the right side of the range trans-
mission. The pump drive housing gears are driven by the PTO drive line and all the pumps turn at approximately 1.33
times engine speed. A PFC (pressure and flow compensating) piston pump is attached to the front of the pump drive
housing, while the tandem gear pumps are attached to the rear of the pump drive housing.
The front section of the tandem gear pump supplies the regulated pressure circuit: brake valve, transmission control
valves, PTO and differential lock valve, auxiliary and hitch valve pilot circuits. The rear section supplies charge flow to
the PFC pump(s). The PFC pump supplies flow to the priority valve, which directs flow to the steering system, remote
valves and the three point hitch.
All hydraulic lines are equipped with O-ring face seals to ensure reliable, vibration-resistant connections.
Charge/lubrication pump
The charge/lubrication pump is the rear section of the dual gear pump and it is used to supply the main PFC pump
with a charged inlet condition to prevent cavitation. The pump also supplies lubrication and cooling requirements for
the transmission.
The pump draws oil from the transmission housing through a 100 mesh suction screen. The pump flow is directed
across the main filter assembly to provide clean charge and lubrication oil.
The pump flow rate at rated speed 2667 RPM( 2000 RPM engine speed) is 177.0 l/min (47.0 US gpm).
Regulated circuit pump
The regulated circuit pump is the front section of the tandem gear pump. The pump draws oil from the system reservoir
through a 100 mesh suction screen. The pump flow passes through the regulated circuit filter housing and into the
priority regulator valve. The priority regulator valve maintains the regulated pressure circuit at 22.4 - 24.5 bar (325
- 355 psi). The regulated pump flow supplies the PTO/differential lock valve, transmission control valves and brake
valve. The remote and hitch valves are also supplied with regulated pressure.
Once these circuits are satisfied, the excess regulated pump flow is directed through the oil coolers and joins up with
the charge pump flow at the downstream side of the main filter head.
The pump flow rate at rated speed of 2667 RPM ( 2000 RPM engine speed) is 102.0 l/min (27.0 US gpm).
PFC piston pump
The axial piston pump has a variable flow output and can operate at variable pressures. The pump matches the
hydraulic power output to the actual load requirements to ensure maximum efficiency and the minimum use of fuel.
The pump inlet is charged to prevent cavitation. The pump output flow is supplied to the priority regulator valve. The
priority regulator valve gives top priority to the steering system and trailer brake circuit. Once the steering system and
trailer brake circuits are satisfied the priority regulator valve supplies pump flow to the remote auxiliary valves and
three point hitch valve.
The maximum pump flow rate for the standard pump at rated speed of 2667 RPM ( 2000 RPM engine speed) is 146.0
l/min (38.6 US gpm).
NOTE: The standard pump system delivers approximately 113.6 l/min (30.0 US gpm) through a single remote sec-
tion. This is due to resistance created by oil flowing through restrictive passage ways and long lengths of tubing or
hose.
Optional high flow PFC piston pump
An optional high flow PFC piston pump is available. The high flow rate maximum pump flow rate at rated speed of
2667 RPM ( 2000 RPM engine speed) is 220 l/min (58 US gpm).
NOTE: The high flow pump system delivers approximately 113.6 l/min (30.0 US gpm) through a single remote sec-
tion. This is due to resistance created by oil flowing through restrictive passage ways and long lengths of tubing or

hose. However, when operating two or more remote sections the high flow pump has approximately 75.7 l/min (20.0
US gpm) more flow than a standard pump system to supply the additional remote circuits.

2. Regulated circuit pump outlet (front section) 4. Dual gear pump/regulated system filter housing
Optional Megaflow PFC piston pump
The axial piston pump has a variable flow output and can operate at variable pressures. The pump matches the
hydraulic power output to the actual load requirements to ensure maximum efficiency and the minimum use of fuel.
The maximum pump flow rate at rated speed 2667 RPM( 2000 RPM engine speed) is 117.0 l/min (31.0 US gpm).
The pump inlet is charged to prevent cavitation. The pump output flow is supplied directly to the remote auxiliary
manifold. The manifold is equipped with internal plugs to separate the dual flow supply flow, signal line pressure and
signal line pilot relief from the standard PFC piston pump circuit. The Megaflow pump supplies only the third, fourth
or fifth remote sections. The two PFC pump hydraulic circuits operate independently.
NOTE: The Megaflow pump system delivers approximately 113.6 l/min (30.0 US gpm) through a single remote sec-
tion. This is due to resistance created by oil flowing through restrictive passage ways and long lengths of tubing or
hose.

Lubrication circuit
The lubrication flow is a combination of both dual gear pumps’ outputs – filtered charge pump flow and filtered/cooled
excess regulated circuit flow. Inlet charge pressure and lubrication are limited to 5.0 bar (75 psi) by a lube relief valve.
The lubrication circuit provides a low pressure flow of oil to lubricate and cool the following transmission components:
master clutch, bevel pinion gears, brakes, drop box, odd/even clutches, MFD/range, creep drive and PTO/differential
lock lube.

Control valve Priority/Regulator valve - Dynamic description
T8010, T8020, T8030, T8040, T8050
The priority/regulator valve assembly is located on the top right side of the range transmission. The assembly
contains:
• the priority spool,
• the regulator spool,
• and steering relief valve.
The front section of the dual gear pump and the pressure and flow compensating (PFC) piston pump supply oil to the
priority/regulator valve.
Priority spool ( supplied by the PFC piston pump)
Oil flows into the priority/regulator valve from the left side port (2). Steering has first priority: oil flows across the
priority spool (11) and out the steering supply port (3). There is a cross-drilled passage near the top of the priority
spool. Oil enters this orifice and starts to build pressure against the spring. As steering demand is satisfied, pressure
builds on the top of the priority spool and the spool moves down against its spring, opening a passage to the remote
and hitch circuits (13).
When the steering circuit is placed on demand, a pressure drop is created on the top end of the priority spool. Signal
and spring pressure work against pump outlet pressure, and the priority spool moves up to accommodate steering
demand.
Once steering demand is satisfied, pressure builds on the top of the priority spool and the spool shifts down to increase
flow to the remote and hitch circuits. When equipped with trailer brakes, oil is also supplied from the priority valve to
the trailer brakes.

Regulator spool (supplied by regulated pump section)
Regulated pump flow enters the priority/regulator valve at the right side port (7). Oil flows across the regulator spool
(12) and supplies all the regulated circuits through the side port (6) and top port (4). The oil also flows through the
orifice near the top of the regulator spool. This oil builds pressure and moves the regulator spool against the spring.

16. DISTRIBUTION SYSTEMS - PRIMARY HYDRAULIC POWER SYSTEM
This regulates pressure and maintains the 22.4 - 24.5 bar (325 - 355 psi) in the regulated circuits. These include the
transmission control valves, PTO/differential lock valve, brake valve and regulated pressure for remote valve and the
hitch valve pilot pressure.
When all regulated circuit demands are met, the regulator spool continues to maintain the 22.4 - 24.5 bar (325 - 355
psi) pressure and allows excess pump flow out the cooler supply port (5).
When a regulated circuit is activated, the regulator spool senses a momentary drop in pressure. The spring will
overcome the spool and move it up to increase flow of oil to meet the demand. As the demand is met, pressure again
builds on the top side of the spool through the orifice and moves the spool down to maintain regulated pressure.

Pressure/flow compensating (PFC) pump - Dynamic description
T8010, T8020, T8030, T8040, T8050
NOTE: The principles of operation for the standard flow pump apply to both the optional high flow pump and Megaflow
pump systems. The illustrations below depict the standard flow pump.
Principle of Control
All remote valves, the hitch control valve, the optional trailer brake and optional power beyond circuit contain a signal
port. Each signal port directs a signal pressure, equal to the working pressure of that circuit, through signal lines
and check valves to the pump compensator spool. The compensator angles the pump swash plate to meet system
demands.
A check valve is located in each signal line between the control valves and the compensator spool. If several control
valves are operated at the same time, the signal line at the highest pressure causes the other check valve(s) at the
lower pressures to seat themselves. This prevents signal bleed off through other control valves and ensures that the
highest signal pressure acts on the compensator spool.
The pump is designed to operate in two different modes according to the demand for flow and pressure. The
modes ares:
• Low pressure standby: When there is no demand for flow or pressure, the pump provides just enough flow to
make up for internal leakage in the hydraulic system at low pressure. In this mode the pump requires very little
power to drive it.
• Pressure/flow delivery and compensation: When there is a demand for flow and pressure from the hydraulic sys-
tem, the pump responds to provide only the flow required. This limits the power consumption of the system.

Low pressure stand by
When there is no demand for flow, there is no pressure signal feedback to the pump, and the pump enters low pressure
standby mode. Since there is no place for pump oil to flow, pressure builds at the pump outlet passage. This pressure
is directed, through internal passages in the pump back plate, to the end of the compensator spool opposite the spring.
The spring acting on the flow compensator spool allows the spool to move at a 23.5 - 27.0 bar (340 - 390 psi) differ-
ential pressure. At this pressure, the flow compensator spool moves down and allows oil to flow into the passage to
the pump control piston.
Pressure on this control piston tilts the pump swash plate against the swash plate control spring to a near neutral
position. In this condition, the pump provides just enough flow to make up for internal leakage, thus maintaining a
minimum system pressure of 23.5 - 27.0 bar (340 - 390 psi).
The pump remains in the low pressure standby position as long as there is no pressure or flow demand from the
hydraulic system. In this mode, the pump produces very little heat and absorbs very little horsepower from the engine.
Engine Start Up
Before the engine is started, the pump swash plate angle is at its maximum angle. As soon as the engine is cranked
by the starter motor, the pressure and flow compensating (PFC) pump produces flow and pressure builds in the pump
84318454 14/03/2010
A.10.A / 112
26. DISTRIBUTION SYSTEMS - PRIMARY HYDRAULIC POWER SYSTEM
delivery passage. When this pressure reaches 23.5 - 27.0 bar (340 - 390 psi) the pump enters its low pressure
standby mode. This occurs almost instantly and makes engine starting easier.
Pressure/flow delivery and compensation
When oil is required in the system, flow is controlled by the difference in pressure at opposite ends of the compensator
spool.
When a control valve is operated, pressure at the outlet of the piston pump drops slightly. Spring and signal line
pressure shift the flow compensator spool away from the spring end, allowing oil from the control piston to drain past
the spool and to tank.
As the oil drains out of the control piston, the swash plate angle increases and pump flow rises until the flow demand
has been met. The flow from the pump is determined by the size of the orifice in the control valve which is being
operated. This orifice is created by limiting the main valve spool travel within the control valve.
When a control valve is operated, oil pressure in the circuit being supplied increases to its operating pressure. This
pressure is transmitted through the sensing line to the spring end of the compensator spool.
Increased flow demand
When an additional control valve is operated, pressure drops slightly at the pump pressure passage. The compen-
sator spool moved up and allows the oil behind the control piston to drain to tank. The swash plate moves and pump
flow increases until the extra demand for flow has been met.
Pressure at the pump outlet increases until it is 23.5 - 27.0 bar (340 - 390 psi) above the signal line pressure. This
pressure increase moves the pump compensator spool against the spring, allowing sufficient flow past the spool to
the control piston. This action on the piston moves the swash plate to a position where increased flow is maintained
and the pressure stabilized.
Decreased flow demand
When flow demand is reduced, pump pressure increases until the pump outlet pressure exceeds the signal line pres-
sure by more than 23.5 - 27.0 bar (340 - 390 psi). The flow compensator spool moves down to allow some oil to flow
into the pump control piston. This action on the piston destrokes the pump against the spring and reduces pump flow.
When pump flow falls to match the reduced demand, the difference in pressure sensed on the opposite sides of the
compensator spool returns to 23.5 - 27.0 bar (340 - 390 psi). The compensator spool moves and blocks off the
passage to the control piston, which locks the swash plate at that pumping angle.
High pressure standby
The hydraulic system is protected by limiting its maximum pressure to 202 - 203 bar (2930 - 2950 psi) through a
signal relief valve. This protection is required, for example, when a hydraulic cylinder reaches the end if its stroke or
when an unconnected remote valve is operated.
NOTE: Hitch system pressure is not limited by a signal relief valve. Hitch system maximum pressure limit is 224 bar
(3250 psi).
When system pressure reaches the setting of the high pressure compensator spool, the pump high pressure com-
pensator spool shifts against its spring, allowing the full pump pressure to be applied to the pump control piston. This
destrokes the pump very rapidly from full stroke to almost zero (within 8 to 10 milliseconds). The swash plate stabi-
lizes to provide just sufficient flow to make up for internal leakage.
The pump remains in the high pressure standby mode until the valve in operation returns to neutral. When this occurs,
signal line feed from the valve is cut off. Signal pressure drops because the drain orifice plug passage is open to the
pump case drain. When there is no signal line pressure, the pump immediately returns to a low pressure standby
condition.
