Installation of Fuel Injection Pump
for electronically controlled engine
Replacing the fuel injection pump involves rewriting the
fuel injection data in the E-ECU.
Be sure to contact your local DOOSAN dealer before
replacing the fuel injection pump.
Failure to rewrite the fuel injection data before replacing the
fuel injection pump will void the engine warranty.
Improper use or misuse of the E-ECU may result in death or
serious injury due to an abrupt and unexpected increase in
engine speed.
If installing a new or recalibrated fuel injection pump, locate
and record the timing index number located on the pump
housing boss on the engine side of the new or recalibrated
fuel injection pump (1, Figure 261). This number will be
used to calculate and adjust the final fuel injection timing.
NOTE: If either or both of the fuel injection pumps do not
have a timing index number, note the injection pump
ID (example: XK42) on the injection pump ID label.
If additional assistance is needed in locating the engine timing
index number and follow the instructions to locate an authorized
DOOSAN industrial engine dealer or distributor for assistance.
NOTE: Treat the timing index number as if it has a decimal
point (68 = 6.8).
1. Align the pump drive gear with the idler gear using the
reference marks made earlier.
