Instructions for Front Wheel Tread Adjustment with Rims for 2, 8, and 16 Positions

IMPORTANT: Observe the following after a track adjustment:

• Tighten all wheel bolts and wheel nuts to the specified torque. Check the torque on the wheel nuts and wheel bolts after 4 and 8 hours of operation and also frequently during the next 100 hours of operation.

• Check wheels for free movement and adjust fenders for the new tread width. 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. See also “Prevent Front Wheel or Fender Contact with Tractor Components” in this Section.

• Set the shut-off angle for the automatic engagement and disengagement of the front-wheel drive¹. See “Engage Front-Wheel Drive” in the “Operate the Tractor — General” Section.

IMPORTANT: The distance between the side wall of the tire and the fender should not be less than 40 mm (1.57 in.)².

The distance between the running surface (edge) of the tire and the fender must not be less than 60 mm (2.36 in.)².

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) has to be 100 mm (3.94 in.).

NOTE: For front loader work, select one of the following tread widths:

Tractors	Recommended tread widths with front loader operation
6110M to 6130M	1750 — 1850 mm (68.9 — 72.8 in.)
6135M and 6145M	1750 — 1950 mm (68.9 — 76.8 in.)

The recommended tread widths are listed in the table “Adjusting the Fender and Steering Stop” of the respective front axle and marked by an *. Refer to this section.

For further information on the front axle type see “Three-Piece Front Axle — Overview of Axle Category and Axle Type” on the following pages.

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 rolling direction of the tires.

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, maintain the rolling direction of the tires.

NOTE: Before adjusting tread width, pay attention to the position of the wheel dish relative to the rim of the front wheel. See illustrations accompanying the tread width tables on the following pages.
