NOTE
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

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.
