FUEL INJECTION NOZZLE REPLACE/REPAIR
Fuel Injection Nozzle Assemblies NSN 2910-01-037-4984 are now being manufactured with
a retaining sleeve and hard (steel) nozzle gasket. The new nozzle assemblies are identified by
stamping 'D1' on the body top. The correct installation torque for the nozzle assembly using
the retainer sleeve and hard steel gasket is 1275-1325 inch-pounds, using torque wrench (item
125, WP 0176).
During repair the retaining sleeve replaces the retaining spring. The hard steel gasket replaces
the soft (copper) gasket. The correct installation torque for the nozzle assembly using the
spring sleeve and soft copper gasket is 490-510 inch-pounds.
Do not mix soft gaskets with solid retaining sleeves or hard gaskets
with spring retaining sleeves. Apply the correct torque for the
application; 1275-1325 inch-pounds for the solid retainer with hard
gasket and 490-510 inch-pounds for the spring retainer with soft
