This 60 l/min centre open circuit is characteristed by 3 hydraulic pumps.

A 19 cm³ pump supplies the braking valve followed by the auxiliary and linkage spool valves.

A 15 cm³ pump supplies first the steering unit, then the 20 bar services.

A 10 cm³ pump that continually lubricates the different transmission components.

E1.15

Hydraulics 60 l/min High-pressure lines The 19 cm³ pump takes oil via a strainer that is common to all the pumps and then passes it through the brake valve then a a filter (capacity 15 microns) and then supplies the linkage spool valve and the auxiliaries. This pump is situated on the right-hand side of the transmission.

1nd step No hydraulic spool valves are operated. The pressure operates a by-pass valve in the auxiliary spool valve supply plate. The excess oil escapes to the reservoir and the remainder lubricates the transmission components.

2nd step One hydraulic spool valve is operated. The by-pass valve delivers the required flow to the consumer and the remainder is directed to the lubrication system. The oil pases throuugh the activated spool valve and supplies the actuator or any other item of hydraulic equipment.

filter (capacity 15 microns). This filter is monitored by a clogging indicator. The steering box is of the open centre type. On the return line from the steering box a valve regulates the pressure to 20 bar; this service pressure supplies the low pressure services, in other words : – Clutch for forward drive, reverse, power take-off, 4 wheel drive, differential, and solenoid valves in the "Hexashift" gearbox. The flow controlled by the 20 bar valve passes through a 60 micron filter (role: to avoid jamming solenoid valves with contamination) and an accumulator (volume: 1 l, pressure 9 bar) which ensures additional flow during short-term high demand periods. A second accumulator (volume: 1 l, pressure 9 bar) is installed in the brake servo system where fitted. This 20 bar valve is located in the left cover. Flow exiting the 20 bar valve then passes through the oil cooler. This cooler is protected by a regulator set at 5 bar, also located in the left cover. The cooled oil will then lubrucate the various transmission components: gearbox, power take-off, rear axle bearings.

Several spool valves are operated at the same time. The spool valve requiring the least force is given priority.

Lubrication system

Low pressure steering and services system

A 10 cm³ pump takes oil via a strainer that is common to all the pumps. The flow of oil from this pump only feeds the transmission lubrication system in addition to the flow delivered by the two other pumps. The excess flow is directed back to the intake via the 5 bar valve.

A 15 cm³ pump takes oil via a strainer that is common to all the pumps then passes it through a high pressure

Fig. 24

The main pump flanged onto the RH plate of the rear axle, consists of 9 pistons (1) driven by a barrel (2) and sliding on a variable angle swashplate (3). It is the variation in the angle of the swashplate that changes the piston stroke and this alters the displacement. If pressure is zero, a

spring (4) pushes the swashplate to its maximum angle. A piston (5), set to oppose the spring, enables displacement to be reduced as a function of the pressure output from the regulator.

– On start up, the pumped oil finds no outlet and its pressure rises and pushes against the 22 bar valve. In this situation, with no power taken, the Xls signal is very low (about 6 bar).

When pump output pressure reaches 22 + 6 = 28 bar, the valve opens and feeds oil from (P) towards (A) to reduce pump displacement virtually to zero.

Before validating to launch the configuration, a connection is required on the head of the manifold to configure.

To perform the configuration, use only the wire (G) from the tractor harness and the resistor (H).

395msm0u

The connection consists in connecting the wire (G) from the tractor harness onto the left-hand plug of the head, and connecting the resistor (H) to the second connector of the head. Here, this connection must be made on the first manifold (left to right) as we checked the first valve (F) in Métadiag©. At that time, it is possible to validate the configuration of the head concerned. This operation must be repeated for each of the heads to configure.

LS Load sensing signal.

Two steering units are available, according to the equipment on the tractor.

– 40 km/h version.

LS

– 50 km/h version.

The "load sensing" steering units have an additional connection (LS) allowing, by means of a hydraulic signal, to inform the supply pump of the level of use of the steering. Should the steering's need increase, the supply pump can increase the flow.

491hsm29

L

Fig. 7

These steering units have two rotor/stator sets. In normal operation, the two rotor/stator sets run together. If a problem occurs on the level of the oil supply of the steering unit, only one rotor/stator set remains active to provide emergency running.

The pressure restricter (7026) limits the supply pressure of the steering unit at a value between 170 to 175 bars.

The dual shock valves (7153) on the steering unit protect the hydraulic circuit. If a major shock interferes with the orientation of the steering wheels, pressure may increase suddenly in one of the jack chambers. This excess pressure is then neutralized by the dual shock valves (7153), which force the oil back into the tank.

– Perform the connection shown in the illustration with tester Nr.00 0178 310 0 and fitting Nr.60 0500 571 8.

– Start the engine.

– Turn the wheels full left.

– Record pressure (A): About 198 ± 2 bar.

– Record pressure in the chamber (B) in return: About 27 ± 2 bar.

The service pressure (setting of the pressure limiter valve) is equal to the sum of these two pressures: 198 + 27 = 225 bars.

– Disconnect one of the two hoses in (A).

– Connect a manual rating pump instead.

– Apply pressure using the rating pump.

– Record the valve's opening pressure.

– The opening pressure (B) must be between 225 and 245 bar.

If the pressure cannot be obtained: – Check the condition of the spring and ball on the valve.

If the problem persists: – Replace the full unit.

– Apply the same procedure to the second outlet of the steering jack unit.
