Standard and Row Crop Drum Style Dual Wheels

a.Row crop drum duals have a longer drum on the outer wheel to give proper spacing for 30" row crops.. Follow the listed procedure for both styles of duals..

b.Put 51 mm - 76 mm (2" - 3") wood blocking under the wheel to be dualed..

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 outside duals 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 outside wheel rim and pilot it onto the planetary studs.. Make sure that the two (3) notches in the outer wheel rim align with the two nuts remaining on the inner wheel rim..

DANGER: THE DRUM-STYLE DUAL 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.

e.Reinstall the 18 nuts (1) removed in Step c..

f.Torque the wheel nuts to 710 N·m (525 ft-lbs)..

g.Repeat the above procedure for the other remaining wheels..

h.Drive the tractor, steering lock to lock.. Park the tractor and recheck the torques on the wheel nuts as described in Step f..
