Tread Settings—Multi-Position Rear Wheels
Wheel tread on the rear axle with multi-position wheels must be adjusted by, repositioning or exchanging the rims or by reversing the wheel disks.
Wheel tread can also be adjusted by exchanging the complete wheel to the opposite side of the tractor (This maneuver permits the change from disk-dished-in to disk-dished-out operations without disassembling the wheel). When changing rear wheels from one side to the other, the arrow on the side wall points in the direction of forward rotation.
The relationship of the wheel disk and rim in obtaining the different tread settings is shown in the diagrams on the facing page.
A study of these diagrams, before attempting to change tread settings, saves unnecessary labor.
IMPORTANT: After setting wheel spacing, tighten rim-to-disk and disk-to-flange bolts. Drive tractor 100 m (109 yd) and tighten again.
