Standard Drum-Style Triple Wheels
a . For triple tire configuration, it is only permissible
to install the inner wheel with the rim inset (narrow
tread width) .
b . Put a 5 mm - 76 mm (2"-3") wood block under
the wheel to be tripled .
c . There are 20 nuts () that retain the inner wheel
to the planetary hub . Remove 8 of the 20 nuts
from the wheel, leaving 2 nuts (2) 80° apart on
the wheel as shown . This will retain the rim to the
hub and fit into the notches (3) on the center wheel’s
rim . Choose the two remaining nuts carefully so that
the valve stem of both wheels are accessable (4) for
easier tire inflation pressure maintenance later .
d . Using an appropriate lifting device, lift the center
wheel rim and pilot it onto the planetary studs .
Make sure that the two slots in the center wheel
rim align with the two nuts remaining on the inner
wheel rim .

NOTE: Install the wheels so that both inner and center
treads face the same direction.
NOTE: Install the center wheel so that the valve stem
is in line with the inner and outer wheels.
e . Reinstall the 8 nuts () removed in Step c .
Torque the wheel nuts to 70 N·m (525 ft-lbs) .

the holes in the center wheel dish with the holes in
the outer wheel drum .
