11.4 Hydraulic Fitting Torque
Tighten flare-type tube fittings:
1. Check the flare and flare seat for defects that might
cause leaks.
2. Align the tube with the fitting before tightening.
3. Hand-tighten the swivel nut until it is snug.
4. To prevent the tube from twisting, use two
wrenches. Place one wrench on the connector body
and tighten the swivel nut with the second wrench.
Torque the fitting to the correct specification.
If a torque wrench is not available, use the flats from
finger tight (FFFT) method.
11.5 Lug Nut Torque
WARNING!
Wheel lug nuts must be installed and kept at
the correct torque to prevent loose wheels,
broken studs, or possible separation of a
wheel from the axle.
It is an extremely important safety procedure to apply and
maintain the correct torque on lug nuts that secure the
wheel to the trailer axle. A calibrated torque wrench is the
best tool to make sure that the correct amount of torque
is applied to a fastener.
Tighten wheel lug nuts to the correct torque before the
first use and after each wheel removal. After a wheel
is installed, check and torque the lug nuts after the
first 10 miles (16 km), 25 miles (40 km), and 50 miles
(80 km). Check the lug nut torque periodically thereafter.
• Start all lug nuts onto the threads by hand.
• Tighten lug nuts in stages, following the pattern
shown below the Lug Nut Torque Specifications
table.
