Operation with Injection Cut Out (One or More Cylinders)
1. Cut Out the Injection
If the injection of one or more cylinders must be cut out, do the procedure give in
steps 1) to 4):
1) In the remote control, select Inj. CUT OFF to cut out the applicable cylinder (see
4002−3 User Parameters and Maintenance Settings, paragraphs 1 and 1.1).
Note: If there is a defect in the injection system (injection valve, high pressure
pipe, etc) only cut out the injection of the related cylinder. If possible, the
exhaust valve must always operate.
2) Disconnect the electrical connections (8) from the rail valves (7) of the related
cylinder (see Fig. 1).
If it is necessary to operate the engine with the injection cut out for an extended
period, do steps 3) and 4):
3) Record the settings of the lubricating oil feed rate.
4) Decrease the lubricating oil feed rate for the related cylinder to the minimum
setting (see 7218−3 Feed Rate − Adjustment).
2. Repair the Defects
Replace defective injection control unit as soon as possible (see the Maintenance
Manual 5564−1 Injection Control Unit).
WARNING
Injury Hazard: You must put on gloves and safety goggles when
you do work on hot components. Oil can come out as a spray and
