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.
4. Turn back the lock nut 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
5. Install the adjustable fitting into the port by hand until the washer contacts the
face of the port (Step 2 in
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
23). Do not rotate the adjustable fitting more than 1 turn counterclockwise.
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.
