ENGINE ASSEMBLY
Checking start of injection
1.Connect fuel tank to injection pump.
2.Bring accelerator lever to max. position and piston, flywheel
side, at compression beginning (cylinder No 1)
All operations are to be carried out with the rack bar in
working position to annul the delay caused by the notch
on the pumping element of the injection pump.
3.Fit the special tool, p.n. 00365R0940, to the delivery valve holder
(flywheel side) as shown in figure 84.
4.Insert a band (fig. 85) to ease the tension of the spring.
5.Turn the flywheel slowly until the column of diesel fuel inside
the special tool starts to move. This indicates the start of static
injection.
At this moment injection pimp delivery starts (fig. 86) and the top
dead centre reference on the air conveyor must coincide with the IP
mark punched cm the flywheel (fig. 87).
If the IP mark falls short of the notch on the air conveyor, injection is
too fast. The injection pimp must be disassembled and shims
must be added between the pump flange and the crank-case.
If the IP mark falls after the T.D.C. reference notch, injection is too
slaw and the above operation is to be inverted.
Bear in mind that every 0.1 mm shim under the pimp corresponds
to a 2.5 mm rotation of the flywheel.
Repeat operation on second pumping element.
Should the flywheel need to be replaced, the top dead center
compression position of the pistons is to be determined as per
page 40 and the start of injection according to the following table:
