Installing an Adjustable Fitting (continued)
3. Lightly lubricate the O-ring with clean hydraulic fluid. Ensure that the threads
of the fitting are clean with no lubricant applied ( Figure 61 ).

4. Turn back the locknut as far as possible. Ensure that the back-up washer is
not loose and it is pushed up as far as possible (Step 1 in Figure 62 ).
IMPORTANT
Before installing the fitting into the port, determine the material of
which the port is made. Installing a fitting into an aluminum port
requires a reduced installation torque.
5. Install the adjustable fitting into the port by hand until the washer contacts the
face of the port (Step 2 in Figure 62 ).
6. If the adjustable fitting needs to align with another component, rotate the fitting
counterclockwise until it is aligned to the desired position (Step 3 in Figure
62 ). Do not rotate the adjustable fitting more than 1 turn counterclockwise.
7. Hold the fitting in the correct alignment with a wrench and use a torque
wrench and tighten the fitting to the recommended torque value within the
specified range of torque values; refer to the
Fitting Installation Torque Table
(page 6–13) . This tightening procedure requires a drive-adapter wrench
(e.g., crowfoot wrench).
Note: It may be necessary to use a drive-adapter wrench (e.g., crowfoot
wrench) to install a hydraulic fitting; refer to Calculating the Torque Values
When Using a Drive-Adapter Wrench (page 2–6) .
8. If a torque wrench is not available or if space at the port prevents the use
of a torque wrench, use the alternative procedure Flat From Finger Tight
Table (page 6–14) given below;
A. Hold the fitting in the correct alignment with a wrench and, if the port
material is steel, tighten the locknut with a second wrench to the listed
FFFT (Step 4 in
Figure 62 ).
B. If the port material is aluminum, tighten the fitting to 60% of the listed
FFFT; refer to the Flat From Finger Tight Table (page 6–14) .
