Mechanical Electronic Injector Unit (MEIU) and Valve Lash Adjustment

1. Put the number 1 piston at Top Dead Center (TDC) on the compression stroke. Refer to the Testing and Adjusting, Finding Top Center Position No. 1 Piston.

   Note: To check that the number 1 piston is on TDC, both the inlet and exhaust valves on cylinder number 1 will move freely. If the valves do not move freely, cylinder number 1 is on TDC of the exhaust stroke. Install the timing pin in the flywheel.

   Table 1

   TDC No. 1 Compression Stroke	Inlet Valves	Exhaust Valves
   Valve Lash	C11 and C13 0.38 ± 0.08 mm(0.015 ± 0.003 inch)	C11 and C13 0.635 ± 0.08 mm(.025 ± 0.003 inch)
   Cylinders	1–2–4	1–3–5

2. Adjust the valve lash using the specifications from Table 1.
   1. Lightly tap the rocker arm with a soft mallet.

      Note: This ensures that the roller lifter seats against the base circle of the camshaft.

   2. Loosen the adjustment locknut for the appropriate valves.
   3. Place the feeler gauge between the rocker arm and the valve bridge.
   4. Turn the adjustment screw in a clockwise direction while sliding the feeler gauge back and forth between the rocker arm and valve bridge. Continue turning the adjustment screw in a clockwise direction until a slight drag is felt on the feeler gauge.
   5. Tighten the adjustment locknut to 30 ± 7 N·m(22 ± 5 lb ft).

      Note: Do not allow the adjustment screw to turn while torquing the locknut.

   6. Recheck the valve lash after tightening the adjustment locknut. Remove the feeler gauge.
3. Follow the steps below to set the mechanical unit injectors on TDC of number 1 piston compression stroke.

   Note: Injectors for cylinders 3, 5, and 6 can be adjusted at TDC of number 1 piston compression stroke.

   1. Loosen the adjustment locknut for the injector.
   2. Turn the adjustment screw clockwise until the screw contacts the mechanical electronic unit injector.
   3. Turn the adjustment screw an additional two turns clockwise to push all of the fuel out of the injector plunger.

      Note: The additional turns will ensure the injector pre-load is set accurately.

   4. Turn the adjustment screw counter-clockwise for 2.5 turns.
   5. Turn the adjustment screw clockwise until the screw contacts the injector.
   6. Turn the screw clockwise an additional 180 degrees or half turn.
   7. Tighten the locknut to 55 ± 10 N·m(41 ± 7 lb ft) while not allowing the adjustment screw to turn for C13 engines. Tighten the locknut to 100 ± 10 N·m(74 ± 7 lb ft) while not allowing the adjustment screw to turn for C15 and C18 engines
4. Remove the timing pin and rotate the engine 360 degrees in the direction of engine rotation. This will put the engine at TDC of number 6 piston. Pin the flywheel with the timing pin.

   Note: To check that the number 1 piston is on TDC, both the inlet and exhaust valves on cylinder number 6 will move freely. If the valves do not move freely, cylinder number 6 is on TDC of the exhaust stroke. Install the timing pin in the flywheel.
