Rear Wheel Tread Adjustment - Rack-and-Pinion Axle (Tractor 6140M)

IMPORTANT: Comply with tread adjustment instructions, and tighten wheel bolts. See Tighten Rear Wheel Bolts (with Rack-and-Pinion Axle).

IMPORTANT: After adjusting tread, check that the wheels can turn freely.

Do NOT let tires come into contact with draft links or lift links. The gap between lift links and tires can be increased by installing the lift links in the front holes of the draft links.

When draft links are raised (even if no implement is attached), the hydraulic or mechanical stabilizer bars must be locked.

If there is still contact with the draft links or lift links despite all these measures, tread width must be increased.

NOTE: In certain countries, overall vehicle width for driving on public roads must not exceed 2.55 m (100 in.).

NOTE: The tread widths shown here apply for the long rack-and-pinion axle.

For maximum tread width with medium-sized and short rack-and-pinion axles, the following values must be subtracted:

• Medium-sized rack-and-pinion axles: 206 mm (8.11 in.)

• Short rack-and-pinion axles: 462 mm (18.19 in.)
