These dual rear wheels should be tightened as follows:
It is recommended that wheel stud nuts
be kept torqued to specifications at all
times. Torque wheel stud nuts to specifi-
cations at each lubrication interval.
• Retighten the wheel nuts in the same
sequence to the torques listed in the
table. Go through the sequence a sec-
ond time to verify that specific torque
has been achieved. Retighten to
specifications at 100 miles (160 km)
and after 500 miles (800 km).
Wheel Nuts
All wheel nuts should be tightened occa-
sionally to eliminate the possibility of
wheel studs being sheared or the bolt
holes in the wheels becoming elongated.
This is especially important during the
first few hundred miles/kilometers of op-
eration to allow the wheel nuts to become
properly set. All wheel nuts should first
be firmly seated against the wheel. The
wheel nuts should then be tightened to
recommended torque. Tighten the wheel
nuts to final torque in increments. Prog-
ress around the bolt circle, tightening the
wheel nut opposite to the wheel nut just
previously tightened until final torque is
achieved.
