Set Tread—Multi-Position Rear Wheels

LV8610-UN-28AUG03

Wheel 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.

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