Installing an Adjustable Fitting (continued)
Hydraulic System: General Information
Before tightening the fitting, determine the material used for the port
the fitting is being installed in. Installing a fitting into an aluminum
port requires reducing the installation torque.
7. Tighten the fitting lock nut (Step 4 in
A. Hold the fitting in the correct alignment with a wrench and use a torque
wrench and tighten the lock nut to the recommended torque value within
the specified range of torque values; refer to the
Table (page 5–16). This tightening procedure requires a drive-adapter
wrench (e.g., crowfoot wrench); refer to
When Using a Drive-Adapter Wrench (page
B. If a torque wrench is not available or if space at the port prevents the use
of a torque wrench, hold the fitting in the correct alignment with a wrench
and tighten the lock nut with a second wrench.
C. If the port material is steel, tighten the fitting to the listed Flats From
Finger Tight (FFFT) value; refer to the
Table (page 5–16).
D. If the port material is aluminum, tighten the fitting to 60% of the listed
FFFT value; refer to the
5–16).
