9.3 Hydraulic Fitting Torque
Tightening Flare Type Tube Fittings
1.
Check flare and flare seat for defects that might
cause leakage.
2.
Align tube with fitting before tightening.
3.
Hand-tighten swivel nut until snug.
4.
To prevent twisting the tube, use two wrenches.
Place one wrench on the connector body and tighten
the swivel nut with the second. Torque to values
shown.
If a torque wrench is not available, use the FFFT (Flats
From Finger Tight) method.

9.4 Wheel Lug Torque
It is extremely important safety procedure to apply
and maintain proper wheel mounting torque on your
trailer axle. Torque wrenches are the best method to
assure the proper amount of torque is being applied to
a fastener.
Wheel lugs should be torqued before first road use and
after each wheel removal. Check and re torque after the
first 10 miles (16 km), 25 miles (40 km), and again at
50 miles (80 km). Check periodically thereafter.
WARNING!
Wheel lug nuts must be installed and
kept at the proper torque value to prevent
loose wheels, broken studs, or possible
separation of wheels from axle.
•
Start all lug nuts onto the threads by hand.
•
Tighten lug nuts in stages, following the pattern
shown in the Wheel Lug Nut Torque table.
