Adjustable Fitting (Fig. 9)
1. Make sure all threads and sealing surfaces of fitting
and c omponent port are free of burrs, nicks, scratches
or any foreign material.
2. As a preventative measure against leakage, it is rec-
ommended that the O- ring be replaced any time the
connection is opened.
3. Lightly lubricate the O- ring with clean hydraulic oil.
Fittingthreads shouldbe cleanwith nolubricant applied.
4. Turn back the lock nut as far as possible. Make sure
the back up washer is not loose and is pushed up as far
aspossible(Step1inFigure10).
IMPORTANT: Before installing fitting into port, de-
termine port material. If fitting is to be installed into
an aluminum port, installation torque is reduced.
5. Install the fitting into the port and tighten finger tight
until the washer contacts the face of the port (Step 2 in
Figure 10). Make sure that the fitting does not bottom in
the port during installation.
6. To put the fittingin the desired position, unscrewit by
the required amount to align fitting with incoming hose
or tube, but no more than one full turn (Step 3 in Figure
10).
7. Hold the fitting in the desired position with a wrench
and use a torque wrench to tighten the lock nut to the
recommended installation torque shown in Figure 8.
This tightening process will require the use of an offset
wrench (e.g. crowfoot wrench). Use of an offset wrench
will affect torque wrench calibration due to the effective
length change of the torque wrench. Tightening torque
when using a torque wrench with an offset wrench will
be lower than the listed installation torque (see Using a
TorqueWrenchwithanOffsetWrenchintheTorque
Specifications section of Chapter 2 - Product Records
and Maintenance).
8. If a torque wrench is not available, or if space at the
port preventsuse ofa torquewrench,an alternatemeth-
od of assembly is the Flats From Finger Tight (F.F.F.T.)
method. Hold the fitting in the desired position with a
wrench and, if port material is steel, tighten the lock nut
withasecondwrenchtothelistedF.F.F.T.(Step4inFig-
ure 10). If port material is aluminum, tighten fitting to
60% of listed F.F.F.T.
