FFWR and TFFT Methods
FFWR (FLATS FROM WRENCH RESISTANCE METHOD)
1.
Tighten the swivel nut to the mating fitting until no lat-
eral movement of the swivel nut can be detected; finger
tight condition.
2.
Mark a dot on one of the swivel hex nut flats and
another dot in line on the connecting tube adapter. See
Figure B.1.
3.
Use the double wrench method per Appendix A, turn
the swivel nut to tighten as shown in Figure B.1. The nut
is to be rotated clockwise the number of hex flats as
defined by the applicable Table in Section 5.0.
4.
After the connection has been properly tightened, mark
a straight line across the connecting parts, not covering
the dots, to indicate the connection has been properly
tightened. See Figure 5-13.
TFFT (TURNS FROM FINGER TIGHT METHOD)
1.
Tighten the swivel nut to the mating fitting until no lat-
eral movement of the swivel nut can be detected; finger
tight condition.
2.
Mark a dot on one of the swivel hex nut flats and
another dot in line on the connecting tube adapter.
3.
Use the double wrench method per Appendix A, turn
the swivel nut to tighten. The nut is to be rotated clock-
wise the number of turns as defined by the applicable
Table in Section 5.0.
4.
After the connection has been properly tightened, mark
a straight line across the connecting parts, not covering
the dots, to indicate the connection has been properly
tightened.
Adjustable Stud End Assembly
For Adjustable Stud End Connections; the following assembly
steps are to be performed:
1.
Lubricate the o-ring with a light coat of hydraulic oil.
2.
Position #1 – The o-ring should be located in the groove
adjacent to the face of the back-up washer. The washer
and o-ring should be positioned at the extreme top end
of the groove as shown.
3.
Position #2 – Position the locknut to just touch the back-
up washer as shown. The locknut in this position will
eliminate potential back up washer damage during the
next step.
4.
Position #3 – Install the connector into the straight
thread box port until the metal back-up washer contacts
the face of the port as shown.
5.
Position #4 – Adjust the connector to the proper posi-
tion by turning out (counterclockwise) up to a maxi-
mum of one turn as shown to provide proper alignment
with the mating connector, tube assembly, or hose
assembly.
6.
Position #5 – Using two wrenches, use the backup
wrench to hold the connector in the desired position
and then use the torque wrench to tighten the locknut
to the appropriate torque.
7.
Visually inspect, where possible, the joint to ensure the
o-ring is not pinched or bulging out from under the
washer and that the backup washer is properly seated
flat against the face of the port.
