Adjusting Tread of Rear Wheels with Reversible Rims

The tread on rear wheels with multiple positions can be adjusted repositioning or changing the rims, inverting the wheel disks.

Tread can also be adjusted switching the whole 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, the arrow on the tire must be pointing in the direction of forward travel.

The relation between wheel disk and rim with different treads is illustrated on the following page. Carefully study diagrams before changing tread as this will reduce effort when performing this task.

IMPORTANT: After adjusting space between rear wheels, tighten bolts between disk and rim and between disk and hub. Drive tractor about 100 m (328.1 ft) and retighten to specification.

Item	Measurement	Specification
Rim-to-disk	Torque	245 Nm (180 lb-ft)
Disk-to-hub	Torque	180 Nm (130 lb-ft)

NOTE: Tread adjustment is measured at the lower part of the center line.
