Wheel Installation - Triple

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 51 mm - 76 mm (2"-3") wood block under the wheel to be tripled..

c.There are 20 nuts (1) that retain the inner wheel to the planetary hub.. Remove 18 of the 20 nuts from the wheel, leaving 2 nuts (2) 180° 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..

DANGER: THE DRUM-STYLE DUAL and triple

WHEELS ARE EXTREMELY HEAVY AND WILL EASILY TIP TOWARD THE DRUM END OF THE WHEEL. USE AN APPROPRIATE LIFTING DEVICE AND SAFETY CHAINS WHEN HANDLING DRUM-STYLE WHEELS.

NOTE: Do not mix up the center wheel with the outer wheel. The center wheel has a dishwelded (5) in the inner diameter to bolt the outside drum to.

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 18 nuts (1) removed in Step c.. Torque the wheel nuts to 710 N·m (525 ft-lbs)..

f.Using an appropriate lifting device, lift the outer wheel and pilot it into the center wheel.. Line up the holes in the center wheel dish with the holes in the outer wheel drum..
