- Break the torque of the injection pump mounting nuts (keeping the nuts snug).
- Rotate the injection pump using Tool T83-9000-C or equivalent to bring the mark on the pump into alignment with the mark on pump mounting adapter.
- Visually recheck the alignment of the timing marks and tighten injection pump mounting nuts.
See Figures 2, 3, 4 and 5
- Bring the engine up to normal operating temperature.
- Stop the engine and install a dynamic timing meter, Rotunda 78-0100 or equivalent, by placing the magnetic probe pick-up into the probe hole.
- Remove the no. 1 glow plug wire and remove the glow plug, install the luminosity probe and tighten to 12 ft.lbs. Install the photocell over the probe.
- Connect the dynamic timing meter to the battery and adjust the offset of the meter.
- Set the transmission in neutral and raise the rear wheels off the ground. Using Rotunda 14-0302, throttle control, set the engine speed to 1,400 rpm with no accessory load. Observe the injection timing on the dynamic timing meter.
Obtain the fuel sample from the vehicle and check the cetane value using the tester supplied with the Ford special tools 78-0100 or equivalent. Refer to the dynamic timing chart to find the correct timing in degrees.
- If the dynamic timing is not within plus or minus 2 degrees of specification, then the injection pump timing will require adjustment.
- Turn the engine off. Note the timing mark alignment. Loosen the injection pump-to-adapter nuts.
- Rotate the injection pump clockwise to retard and counterclockwise to advance timing. Two degrees of dynamic timing is approximately 0.030 inch; (0.76mm) of timing mark movement.
- Start the engine and recheck the timing. If the timing is not within plus or minus 1 degree of specification, repeat steps 7 through 9.
- Turn off the engine. Remove the dynamic timing equipment. Lightly coat the glow plug thread with anti-seize compound, install the glow plugs and tighten to 12 ft.lb. Connect the glow plug wires.
