Remove the air manifold (10) from the inlet manifold without
disconnecting the electric cables and the fuel pipe.
Put the air manifold (10) appropriately to one side in the
engine bay. Take out the side soundproofing cover (if any)
and the top cover (11). Remove the injectors (17 or 13), the
fuel recovery pipe (16) and the fuel pipes (15). For engine
8140.43C, take out the screws (18) securing the injector
brackets and remove the injectors from the cylinder head.
For engine 8140.63, unscrew the injectors (13).
For assembly, carry out the operations described for disas-
sembly in reverse order, taking the following precautions:
- tighten the injectors of engine 8140.63 at a torque of 60
Nm (6 kgm);
- bleed the fuel air as described under the relevant heading.

disconnecting the fuel pipe and electric cables from the
thermostart components. Put the transverse air manifold
(10) appropriately to one side in the engine bay.
Remove the top (11) and side (if any) soundproofing covers.
Remove the timing cover (6). Turn the crankshaft so as to
align the camshaft pulley mark A with the tappet cover mark
B, making it possible to insert tool 99360608 into the hole
(5) in the pulley and into the hole in the auxiliary member
assembly. If this is not possible, turn the crankshaft by one
turn.
Remove the pipe bracket for the oil dipstick (7) from the
auxiliary member assembly.
Disconnect the following from the injection pump:
- Electric cables:
D (9), KSB device.
D (14), electrostop.
D (12), EGR potentiometer (if present);
