Adjusting Front Wheel Tread

4x4 front axle tread with reversible rims can be adjusted repositioning or changing the rims or inverting wheel disks.

Tread can also be adjusted switching the entire wheel to opposite side of tractor. (This maneuver allows a concave to convex wheel position change without having to disassemble them).

When changing rear wheels from one side to the other of front axle with 4x4 wheel drive, the arrow on the tire must be pointing in direction of forward travel.

The relation between wheel disk and rim with different treads is illustrated in the continuation of this manual.

Carefully study diagrams before changing tread as this will reduce effort when performing this task.

After adjusting space between front wheels, tighten nuts between disk and rim and between disk and hub. Drive tractor about 100 meters (328.1 ft.) and retighten nuts to specification.

Disk-to-Hub	Torque	310 N·m (229 lb.-ft.)
Rim-to-Disk	Torque	245 N·m (180 lb.-ft.)

Nuts must be mounted on outside face of wheel.

Always measure tread width at the lower part of tire center line.
