After adjusting tread, tighten the wheel bolts.

IMPORTANT: After adjusting the tread, check wheels for free movement and adjust fenders for the new tread width. For this, turn the steering to full lock in both directions and oscillate the axle to the stops.

Adjust the steering stops to prevent the wheels from coming into contact with tractor components.

IMPORTANT: The distance between the side wall of the tire and the fender must not be less than 40 mm (1.57 in.)¹.

The distance between the running surface (edge) of the tire and the fender must not be less than 60 mm (2.36 in.)¹.

If snow chains are installed on the tires, the minimum distance from the tires to the fenders (side wall to fender and running surface to fender) must be 100 mm (3.94 in.).

NOTE: Wheel tread on tractors equipped with a front loader must not exceed 1.90 m (75 in.).

Front wheels with rims for 2 positions

The tread width can be changed by mounting the complete tires on the other tractor side. In doing so, maintain the direction of tire rotation.

Front wheels with rims for 8 and 16 positions

Wheel tread can be adjusted by repositioning or reversing the wheel rims.

In addition, the complete wheel can be installed on the other side of the tractor. In doing so, observe the direction of tire rotation.

After adjustment has been completed, tighten wheel retaining bolts to specified torque (see Section Break-In Period).

The relationship of the front wheel disk and rim in obtaining the different tread settings is shown in the following drawings. Pay attention to this information before setting the tread.

IMPORTANT: After adjusting wheel tread, retighten all wheel attaching nuts after 4 and 8 hours of operation. Check tightness of these nuts frequently during the next 100 hours of operation.
