9. Rotate the engine forward, clockwise from the front, to the injection timing mark.
NOTE: The injection timing mark is a line scribed in the flywheel approximately 35 mm from the TC mark. The injection
timing mark has no identification markings.
10. The dial indicator should now show the pump plunger is at 0.5 mm from the bottom of its stroke and ready to inject fuel.
11. If the timing position is not correct, loosen the 3 (or 2) bolts on the front flange of the pump.
12. If the dial indicator shows a figure larger than 0.5 mm, rotate the top of the pump away from the engine until the dial indicator
reads the correct value. A figure less than 0.5 mm requires the pump be turned in towards the engine until the correct value
is reached. Tighten the three bolts and lock the pump in position.
13. Perform a final check by turning the engine backwards, counter clockwise from the front, beyond the injection timing mark
and then clockwise back to the injection timing mark. The dial indicator should now read 0.5 mm. Slight adjustments may be
necessary.
14. Remove the dial indicator and replace the 8 mm timing bolt.
