Checking the extra-fuel device:
– After assembly, check free movement
of the extra-fuel device's piston by pul-
ling it out and letting it slide back; see
Fig. 108.
Attaching:
– The extra-fuel device is installed by fol-
lowing the removal instructions in the
opposite order, taking particular care
that the gasket is correctly installed as
shown in Fig. 109 and the scribed mark
is noted. Apply sealant
H
to both sides
of the gasket. Only a thin coat should
be applied, so that the oily in the extra-
fuel device is not blocked. Install the
machine screws with sealant
D
.
Adjusting the extra-fuel device:
– Piston (107/4) also acts as the full-load
stop for the governor lever and is
eccentrically located in the cylinder
(107/1).
The effective stroke and, therefore, the
maximum injected fuel volume are
adjusted by turning this cylinder.
For effective stroke requirements and ad-
justing procedure, see M 14.00.
If
the same
extra-fuel device is detached
and re-attached, the effective stroke does
not have to be adjusted, provided that the
setting of the volume limiting eccentric
was not altered.
