DISASSEMBLY

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

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.

CAUTION

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

gasket.
