6.5 Modiication of the injector
metered volume
The GVP lubrication system is delivered with a ixed metered volume.
It is possible to modify later this metered volume. Four different
metered volumes are available: 0,33 ; 0,5 ; 0,75 or 1 cm
3
/stroke.
The metered volume is adjusted by means of reversible metering
stops. They modify the stroke of the metering piston of the injector,
thus the metered volume. Each injector has two reversible metering
stops
(† ig. 14)
, one is mounted in the injector, the other delivered
separately.
NOTE
A number of washers screwed on the injector indicate the mete-
red volume of the GVP system
(† ig. 15)
. Therefore change the
number of washers when modifying the metered volume.
