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
