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 modied (see g. 174).
Following to this modication and others like the
elimination of cap 20 of (g. 169) the method of checking
the static injection advance has changed as well, (g.
187-188) as that of injector setting (g. 178).
