1. Ensure that all the threads, the sealing surfaces of the hose/tube, and the
fitting are free of burrs, nicks, scratches, or unwanted material.
2. Align the hose/tube against the body of the fitting so that the face of the
hose/tube sleeve fully touches the face of the fitting.
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 2–5) .
3. Use your hand to thread the swivel nut onto the fitting. While you hold the
hose/tube in alignment with a wrench, use a torque wrench to tighten the
swivel nut to the recommended torque value within the specified range of
torque values; refer to the
Hose/Tube Installation Torque Table (page 5–12) .
IMPORTANT
The hydraulic hoses used on the GreensPro 1240 machines have
BSPP (British Standard Parallel Pipe) threads. The hydraulic hoses
used on the GreensPro 1260 machines have ORFS (O-Ring Face
Seal) threads. If hoses are replaced, ensure that the replacement
has the correct type of threads, or component damage and leakage
will occur.
Hose/Tube Installation Torque Table
Size Hose/Tube Thread Size Installation Torque
3/8 BSPP 19 30 to 35 N∙m (22 to 26 ft-lb)
6 ORFS 11/16–16 37 to 44 N∙m (27 to 33 ft-lb)
8 ORFS 13/16–16 51 to 63 N∙m (37 to 47 ft-lb)
4. If a torque wrench is not available or if space at the swivel nut prevents the
use of a torque wrench, use the alternative procedure Flats From Wrench
Resistance (FFWR) given below.
