If you need to change the position of the discs and rims of the wheels,
use the following procedure:
1. Put blocks at the front wheels, lift the rear of the tractor and put blocks
under the tractor.
2. Remove six wheel mounting bolts at each wheel to remove rear wheels
from rear axle.
3. Remove wheel disc from the wheel rim at each wheel.
4. Install the wheel discs and rims in the required position shown in the
Rear Wheel Tread Positions in this manual.
5. Tighten the wheel rim to wheel disc nuts to a torque of 152 to 172 Nm
(112 to 127 lb ft).
6. Put the rear wheels on the rear axle and tighten the wheel mounting
bolts with hardened washers to a torque of 118 to 132 Nm (87 to 98 lb ft).
NOTE: When putting the wheels on the axle, make sure that the tires rotate
in the correct direction. See Tire Installation in this manual.
IMPORTANT: When adjusting wheels, check nut and bolt torques after
10 hours of operation and every 100 hours thereafter.
