to the thread and the seating surface of
the coupling nut (2, Fig. 5 ).
3) Attach the coupling nut (2) to the pilot
injection valve (1) with your hand.
4) Refer to the formula shown, where:
D TS = the applicable torque setting
for the torque spanner.
D TT = the specified torque setting
for the coupling nut (2).
D D1 = the distance from the center
of the square drive to the center of
the hand grip.
D D2 = the distance from the center
of the square drive to the center of
the adapter.
5) Use the torque wrench (94012) and the
wrench extension (94269C − 55) to
torque the coupling nut (2)
