Installing the Hydraulic Fittings
IMPORTANT
The hydraulic fittings used on the GreensPro 1240 have BSPP
(British Standard Parallel Pipe) threads for the hose connections,
and both SAE and BSPP threads for the component connections.
The hydraulic fittings used on the GreensPro 1260 have ORFS
(O-Ring Face Seal) threads for the hose connections, and both
SAE and BSPP threads for the component connections. Pay close
attention to the fitting thread type and the type of seal used when
replacing hydraulic tank fittings and seals, or component damage
and leakage may occur.

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 5–16)
.
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 2–5)
.
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.
