Pump/injector unit
Designed by KOHLER, the pump/injector is exclusive to KDW
702-1003-1404 series engines.
The injection system includes two, three, four identical pumps/
injector units, each one of which feeds a cylinder.
Note: On pumps/injector units of recent construction (for serial
numbers and references see the table on page 88) the
pump has been modified (see fig. 174).
Following to this modification and others like the
elimination of cap 20 of (fig. 169) the method of checking
the static injection advance has changed as well, (fig.
187-188) as that of injector setting (fig. 178).
