Injector Mechanism (Typical example)
(1) Rocker arm
(2) Adjusting screw
(3) Locknut
(4) 9U-7227 Injector Height GaugeTo adjust the unit injectors on cylinders 3, 5, and 6 use the following procedure:
Put the No. 1 piston at the top center position on the compression stroke. Refer to Testing and Adjusting, "Finding Top Center Position for No. 1 Piston".
Injector height gauge (4) is used to obtain a dimension of 78.0 0.2 mm (3.07 0.01 inch). The dimension is measured from the top of the unit injector to the machined ledge of the fuel injector body.
Set the injector height tool body on top of the injector tappet body. The rod of the height adjustment tool should sit on the machined ledge of the injector body.
Turn unit injector adjusting screw (2) clockwise until the correct height is obtained.Note: The top of the injector height tool rod has two steps on it. The middle of the steps should be flush with the injector height tool body.
Hold the adjusting screw in this position and tighten locknut (3) to a torque of 100 10 N m (74 7 lb ft).
To adjust the unit injectors on cylinders 1, 2, and 4, remove the timing bolt. Turn the flywheel by 360 degrees in the direction of engine rotation. The direction of engine rotation is counterclockwise, as the engine is viewed from the flywheel end. This will put the number 1 piston at the top center position on the exhaust stroke.
Repeat Steps 3 through 4.
Remove the timing bolt from the flywheel after all the unit injector adjustments have been made. Reinstall the valve mechanism cover.MEUI C Injector Overview

Typical MEUI C injector
(1) Tappet
(2) Electrical connectorMechanical Electronic Unit Injectors (MEUI) C have the typical features that are shown in Illustration 3. The injectors typically have a raised tappet (1), and electrical connector (2).MEUI C Injector Adjustment
Set the engine to Top Dead Center (TDC) for number 1 piston. Refer to Testing and Adjusting, "Finding Top Center Position for No. 1 Piston".
Set injectors 3, 5, and 6 using the procedure that follows.
Turn the adjustment screw clockwise for the injector rocker mechanism until it touches the top of the injector.
Turn the adjustment screw an additional 180 degrees clockwise.
Hold the adjustment screw and torque the nut to 55 10 N m (41 7 lb ft).
To adjust injectors 1, 2, and 4 rotate the engine 360 degrees and pin the flywheel.
Turn the adjustment screw clockwise for the injector rocker mechanism until it touches the top of the injector.
Turn the adjustment screw an additional 180 degrees clockwise.
Hold the adjustment screw and torque the nut to 55 10 N m (41 7 lb ft).
