AS REQUIRED
h. Add a jam nut, 1, to both ends of the tie rod
and torque the jam nut to 320 N⋅m (235 ft.
lbs.).
i. Repeat the above procedure for the
remaining three sets of duals.
j. Drive the tractor steering from lock to lock.
Park the tractor and recheck the torques on
the outer wheel nuts as detailed in Step g.
4. Standard and row crop drum style dual
wheels.
a. Standard and row crop drum style duals
are assembled the same way. 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. Put51 mm - 76 mm (2″ -3″) woodblocking
under the wheel to be dualed.
c. There are 16 nuts, 1, that retain the inner
wheel to the planetary hub. Remove 14 of
the 16 nuts from the wheel, leaving two
nuts, 2, 180° aparton the wheel as shown.
This will retain the rim to the hub and fit
into the notches on the outside duals rim.
Choose the two remaining nuts c arefully
so that the valve stem of both wheels will
align for easier tire inflation pressure
maintenance later.
