O-ring
1. Ensure that all the threads, the sealing surfaces of fitting, and the component
port are free of burrs, nicks, scratches, or unwanted material.
2. To help prevent a hydraulic leak, replace the O-ring when you open the
connection.
3. Lightly lubricate the O-ring with clean hydraulic fluid. Ensure that the threads
of the fitting are clean with no lubricant applied.
IMPORTANT
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.
4. Install the fitting into the port, then use a torque wrench and socket to tighten
the fitting to the recommended torque value within the specified range of
torque values; refer to the
Fitting Installation Torque Table (page 5–12)
.
Note:
It may be necessary to use a drive-adapter wrench (e.g., crowfoot
wrench) to install a hydraulic fitting; refer to
When Using a Drive-Adapter Wrench (page 2–7)
.
5. If a torque wrench is not available or if space at the port prevents the use of
a torque wrench, use the Flats From Finger Tight (FFFT) procedure given
below:
A. Install the fitting into the port and tighten the fitting down full length until
finger-tight.
B. If the port material is steel, tighten the fitting to the listed value; refer to
the
Flats From Finger Tight (FFFT) Table (page 5–12)
.
C. If the port material is aluminum, tighten the fitting to 60% of the listed
value; refer to the
Flats From Finger Tight (FFFT) Table (page 5–12)
.
