1. Clean injector seating (A) with tapered brush.
2. Clean injector bore (B) with small bore brush.
END OF TASK
INSTALLATION
NOTE
If fuel injector is replaced, the new injector electronic injector code must be programmed into the
engine personality module software using the calibration menu. If the new code is not entered,
the previous unit injector's characteristics will be assumed.
If it is not possible to immediately reprogram the new injector code, the engine will not be
severely harmed, but the new code should be entered as soon as possible to optimize engine
performance.
1. If new injector is being installed, record the new injector code (Figure 1, C), located on the solenoid.
2. Lightly lubricate three seals (Figure 1, D) and the bore (Figure 1, B) with engine oil.
3. Position unit injector (Figure 1, Item 1) on cylinder head. Push down on injector spring to seat unit injector
(Figure 1, Item 1).
4. Install clamp (Figure 1, Item 4), spacer (Figure 1, Item 3) and bolt (Figure 1, Item 2) and tighten bolt. This will
completely seat the unit injector (Figure 1, Item 1). Torque bolt (Figure 1, Item 2) to 17-27 lb-ft (23-37 Nm).
5. Connect unit injector harness connector.
6. Repeat steps 1 thru 5 for remaining unit injectors.
7. Install rocker shaft and pushrods (WP 0119).
