A continuación le envio el procedimiento tomado del manual, lamentablemente el manual solo viene en ingles y espero sea de su utilidad, recuerde valorar el servicio mediante las estrellas.

  1. 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".
  1. Injector height gauge (4) is used in order 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.
  1. Turn unit injector adjusting screw (2) clockwise until the correct height is obtained.
  1. Hold the adjusting screw in this position and tighten locknut (3) to a torque of 100 ± 10 N·m (74 ± 7 lb ft).
  1. To make an adjustment to 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.
  1. Repeat Steps 3 through 4.
  1. Remove the timing bolt from the flywheel after all the unit injector adjustments have been made. Reinstall the valve mechanism cover.

Here is procedure for setting valves

Valve Lash

ValvesGauge Dimension

Inlet
0.38 mm (0.015 inch)

Exhaust
0.76 mm (0.030 inch)

Adjust the valve lash while the engine is stopped. Use the following procedure in order to adjust the valves:

  1. Put the No. 1 piston at the top center position.

    Note: If the engine is equipped with an engine compression brake, loosen the adjusting screw for the lash on the slave piston for the compression brake prior to adjusting the engine valve lash. Refer to the Testing and Adjusting, "Slave Piston Lash - Adjust" topic in order to adjust the slave piston lash.

    Note: See Testing and Adjusting, "Finding Top Center Position for the No. 1 Piston" for further details.

  1. With No. 1 piston at the top center position of the compression stroke, an adjustment can be made to the valves.

    Before any adjustments are made, lightly tap each rocker arm at the top of the adjustment screw. Use a soft mallet to ensure that the lifter roller seats against the camshaft's base circle.

  1. Make an adjustment to the valve lash on the inlet valves for cylinders 1, 2, and 4.
    1. Loosen valve adjustment locknut (3) .
    1. Place the appropriate feeler gauge (5) between the inlet rocker arm and the inlet valve bridge. Turn inlet adjustment screw (4) while valve adjustment locknut (3) is being held from turning. Adjust the valve lash until the correct specification is achieved. Refer to Table 2.
    1. After each adjustment, tighten valve adjustment locknut (3) while valve adjustment screw (4) is being held from turning. Tighten to a torque of 30 ± 7 N·m (22 ± 5 lb ft). Recheck each adjustment.
  1. Make an adjustment to the valve lash on the exhaust valves for cylinders 1, 3, and 5.
    1. Loosen valve adjustment locknut (1) .
    1. Place the appropriate feeler gauge (5) between the exhaust rocker arm and the exhaust valve bridge. Turn exhaust adjustment screw (2) while valve adjustment locknut (1) is being held from turning. Adjust the valve lash until the correct specification is achieved. Refer to Table 2.
    1. After each adjustment, tighten valve adjustment locknut (1) while valve adjustment screw (2) is being held from turning. Tighten to a torque of 30 ± 7 N·m (22 ± 5 lb ft). Recheck each adjustment.
  1. Remove the timing bolt, and turn the flywheel by 360 degrees in the direction of engine rotation. This will position the No. 6 piston at the top center on the compression stroke. Install the timing bolt in the flywheel.
  1. Make an adjustment to the valve lash on the inlet valves 3, 5, and 6.
    1. Loosen valve adjustment locknut (3) .
    1. Place the appropriate feeler gauge (5) between the inlet rocker arm and the inlet valve bridge. Turn inlet adjustment screw (4) while valve adjustment locknut (3) is being held from turning. Adjust the valve lash until the correct specification is achieved. Refer to Table 2.
    1. After each adjustment, tighten valve adjustment locknut (3) while valve adjustment screw (4) is being held from turning. Tighten to a torque of 30 ± 7 N·m (22 ± 5 lb ft). Recheck each adjustment.
  1. Make an adjustment to the valve lash on the exhaust valves 2, 4, and 6.
    1. Loosen valve adjustment locknut (1) .
    1. Place the appropriate feeler gauge (5) between the exhaust rocker arm and the exhaust valve bridge. Turn exhaust adjustment screw (2) while valve adjustment locknut (1) is being held from turning. Adjust the valve lash until the correct specification is achieved. Refer to Table 2.
