Tread Settings-Multi-Position Rear Wheels-Early Model TractorWheel tread on rear axle with multi-position wheels can 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 side wall of tire 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, will save unnecessary labor. IMPORTANT: After setting wheel spacing, tighten rear wheel disk-to-hub and rear wheel rim-to-disk bolts to specification. Drive tractor 100 m (109 yd) and tighten again. |
