Installation of the Electronic Unit Injector

Position a 0.762 mm (0.030 in.) feeler gage between the crab and injector spring on the side of the spring that faces the intake manifold.
Install the hold-down crab, hemispherical crab washer (flat surface up against bolt) and hold-down bolt to the injector. Ensure the clamp does not interfere with the injector spring or valve springs.
Torque the hold-down bolt to 58-66 N · m (43-49 lb · ft).
Install the EUI terminal wires by positioning the keyhole in the terminal over the screw in the injector solenoid housing. Pull the terminal end down so that the screw rests in the smaller slot in the terminal. Torque the terminal screws to 1.08 – 1.13 N · m (9.5 – 10.0 lb · in.). Do not bend the terminals down after installation.
Install the rocker arm shafts, with rocker arms in place.
Adjust the intake and exhaust valve clearances and injector height.
Install the inlet and outlet fuel lines to the fittings at the rear of the cylinder head.
On DDEC III/IV engines, record the injector calibration code from the load plate with the proper cylinder location.
Install the valve rocker cover.
For one-piece valve rocker cover. For two-piece and three-piece valve rocker cover.
Verify repair of electronic unit injector.
