10.3 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.
10.4 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.
