Wheel Removal/Installation
To remove the outer wheel, proceed as follows:
• Block the front wheels, front and rear, then jack
up and support the rear axle.
WARNING
Before removing a wheel, make sure it is
securely supported.
• Remove the ten wheel disc to hub bolts from the
wheel and lower the wheel to the ground using a
suitable lifting device. Repeat on the other wheel.
When reinstalling the outer wheels, torque the disc to
hub bolts in an alternate pattern to 800 N·m (590
ft.-lbs.).
Inner Wheels
The manual adjust inner wheels can be adjusted in
the same way as manual adjust single wheels.
However, due to interference between inner and
outer tires or between the inner tires and the fenders,
limited track settings may be achieved.
To adjust the inner wheels, first remove the outer
wheels as described under “Outer Wheels.”
Follow the instructions under “Rear Wheels Track
Adjustment” in order to adjust the track width of the
inner wheels.
NOTE: Check wheel hardware torque after driving
the tractor for 200 m (200 yards), after 1 hour, and 10
hours of operation and thereafter at the 50-hour
service interval.
