9.2 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.

9.3 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.
NOTE:
Wheel lugs must be applied and
maintained at the proper torque levels to
prevent loose wheels, broken studs, and
possible dangerous separation of wheels
from your axle.
•
Start all lugs by hand to prevent cross threading.
•
Tighten lugs in sequence, per wheel lug torque
sequence chart.
•
The tightening of the fasteners should be done in
stages. Following the recommended sequence,
tighten fasteners per wheel torque requirements
chart.
