1. Adjustment of the aneroid compensator
(1)Adjust with the (D) set screw so that the clearance between the (A) housing and (B) snap ring is L1.
(2)Select the push rod (E) so that the distance from the end surface of the (F) spacer becomes L2.
(3)(C) Turn the screw to adjust the beginning of aneroid compensator operation.
2. Adjustment when mounting the governor.
(1)Set the speed of the pump to N1 r/min and fix the control lever at the full set position.
(2)Adjust using screw C to obtain the performance shown in the graph above.
(3)After final adjustment, confirm that the gap between housing (A) and snapring (B) is L3.

August 31, 1989
Problem
Certain 7000 Series fuel injection nozzles may crack and loose their nozzle tips if there is a small indentation or dent in the nozzle between the tip end and the carbon dam.
Action Required
Inspect the following nozzles in parts stock for any small indentations or dents in the tip of the nozzle between the carbon dam groove and the tip end of the nozzle. Remove all nozzles from parts stock that have indentations or dents that are deep enough to be felt with a thumbnail. See the illustration. 8N7003 4W7015 7W7023 8N7005 4W7016 7W7024 8N7006 4W7017 7W7026 4W7018 7W7030 4W7019 7W7031 4W7020 7W7032 4W7021
