Tread Settings—Multi-Position MFWD Wheels

LV601-UN-22APR94

LV602-UN-22APR94

Wheel tread on the MFWD axle with multi-position wheels is 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 MFWD wheels from one side to the other, the arrow on the side wall of tire points in the direction of forward rotation. In certain applications, MFWD equipped tractors operates with the arrows in the opposite direction. (See Selecting Front Tire Rolling Direction in this section.)

The relationship of the wheel disk and rim in obtaining the different tread settings is shown in the diagrams. A study of these diagrams, before attempting to change tread settings, saves unnecessary labor.

Tread settings are measured at the middle of the tires at axle height.

IMPORTANT: After setting wheel spacing, tighten MFWD wheel rim-to-disk bolts and MFWD wheel disk-to-hub bolts to specification. Drive tractor 100 m (109 yd) and tighten again.
