Installing the Hydraulic Fittings (SAE Straight Thread O-Ring
Fitting into the Component Port)
Installing the Non-Adjustable Fittings
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.

1. Fitting 2. O-ring
3. Lightly lubricate the O-ring with clean hydraulic fluid. Ensure that the threads
of the fitting are clean with no lubricant applied ( Figure 60 ).
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.
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 6–13) .
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) .
5. 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 6–16) 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 FFFT. If the port
material is aluminum, tighten the fitting to 60% of the listed FFFT.
