1) The document provides identification information and descriptions of components for the fuel injection system of various tractor models, including the injector pump, fuel pump, fuel filter, injectors, and related electrical components. 2) It describes the operating principles of the fuel injection system and components such as the injector pump, which uses a rotary distributor piston to regulate fuel pressure and distribute fuel to the injectors. 3) Check and adjustment procedures are provided for components like the accelerator control, injector pump settings, injector pressure, and fuel supply pressure. Removal and refitting instructions are also given for the fuel filter.

Description

Operating principle
Fuel is drawn from the fuel tank by the camshaft-driven
fuel pump located on the engine block . The fuel then
passes through the filter (19) to the transfer pump suction
chamber inlet. The transfer pump (vane type) is located
inside the injector pump and its role is to raise fuel
pressure as a function of increases of engine rpm. The
fuel then arrives at the valve that regulates the pressure
within the injector pump. The distributor piston later raises
this pressure and sends the fuel to the injectors via the
outlet connector. Excess fuel is recovered and returned to
the tank.

Checks/Adjustments
– Attach the control cable to the accelerator lever on the
injector pump (100).
– Connect the control cable to the accelerator pedal
(101).
– Check in the cab that the manual control lever is set to
minimum "A" (Fig. 19).
– Adjust the cable at the pedal end to achieve a light
tension then tighten the nuts (102). Ensure that the pump
lever is tight against the idle speed adjustment
screw (103).
– Adjust the manual control cable (105) then tighten the
nuts (106).
– Correct adjustment should enable the engine throttle
control (104) to return to the mechanical stop (103)
when the lever or the pedal is at its minimum setting and
enable an extension of the accelerator cable spring on
the pump when the manual lever or the pedal is at its
maximum setting.
Injector pump
Internal setting
The pump must be removed and cylinder n° 1 must be at
TDC on the compression stroke (refer to chapter
"Removal/refitting", "Injector pump").
– Remove the central screw (101) on the distributor
head.
– Align the keyway slot in the shaft with the outlet for
cylinder n° 1 item (B) for the 4 cylinder pump (5b) and
item (A) for the 3 cylinder pump (5a).
– Mount the pump shaft in a soft-faced vice.
– Attach tool (89) reference n° 60 05 005 560 with the
dial gauge (88) placing the shaft in contact with the head
of the distributor piston.
– Install the dial gauge at mid travel.
– Turn the pump so that the shaft turns clockwise until
the needle stops moving.
– Set the dial gauge to zero.
– Turn the pump so that the shaft turns anti-clockwise
until the dial gauge reads 1 for turbo-charged engines
and 1,15 for normally aspirated engines.

pump (refer to chapter "Removal/refitting", "Injector
pump").
– Check the pump installation (refer to paragraph
"Checking the timing of the injector pump").
Checking the timing of the injector pump
N° 1 cylinder must be at TDC on the compression stroke
(refer to chapter "Removal/refitting", "Injector pump").
The pump must be attached to the engine block with the
pump shaft free and the operating lever attachment nut
tightened.
– Remove the central screw on the distributor head.
– Attach tool (89) reference n° 60 05 005 560 with the
dial gauge (88) placing the shaft in contact with the head
of the distributor piston (Fig. 22).
– Install the dial gauge at mid travel.
– Turn the engine flywheel against the normal operating
direction until the dial gauge needle stops moving.
– Set the dial gauge to zero.
– Turn the engine flywheel in the normal operating
direction to return to TDC (replace the flywheel locking
pin). The dial gauge should show a reading of 1 for
turbo-charged engines and 1,15 for normally aspirated
engines.
– If these values are not obtained, slacken the 3 pump
attachment nuts and rotate it clockwise or anti-clockwise
to obtain the desired reading.
– Re-tighten the 3 pump attachment nuts.

Checks/Adjustments
Injector
Instructions for the removal of the injectors will be found in
the chapter "Removal/refitting of injectors".
Check the injector's pressure setting (see chapter
"identification" for pressure values).
Note: It is recommended to aim for the maximum
value in the adjustment because after operating for
some time the pressure drops slightly before
stabilising. Repeat the adjustment in order to obtain a
reliable result.
Note: The injector nozzle must never be pointing
towards the person performing the adjustment. The
jet escaping from a port can pierce clothing and skin,
and cause serious infections. The jet should be
recovered in a transparent container.

18. Nectis 207 – 12.2005 – GB A2.19
Checks/Adjustments
Supply pressure
– Create a test installation as shown in figure n° 22 to
check the fuel supply pressure.
– Connect the ends of the lines (100a) to the filter
outlet (19), (100b), to the injector pump inlet (5), (100c)
and to the reference pressure gauge n° 60 05 005 521.
– Start the engine.
– Check the pressure (refer to chapter A1
"measurement and test points" for pressure values).
– If the pressure is low, check the supply system (filter,
strainer, hoses) and re-test.

Removal of the fuel filter bracket
– Place a container under the fuel filter and unscrew the
condensation drain covers under the filter. Drain out all
the fuel present.
– Unscrew fully the valve and remove the fuel filter (19).
– Disconnect the fuel lines (20), (21) from the feed pump
to the filter bracket and from the latter to the injector
pump.
– Remove the fuel filter bracket (42).
To disconnect the fuel lines (20), (21) (Fig. 25), press
down on the fastener (54) as shown in figure (B). After
disconncting the lines, withdraw the fastener (54) to its
locked position (Fig. A).
Refitting the fuel filter
Proceed in reverse order to the removal operations.
N.B.: Before refitting the fuel filter (19), it must be
refilled with fuel to facilitate the bleeding of the fuel
feed system.
