DANGER!
Tire Changing Procedure
CHANGING TIRES
To prevent personal injury when changing tires on
the implement, always block raised section. Be
sure section is stable before proceeding. Never
rely on a jack or hydraulic device to support raised
implement
The tires on the center section or the air drill are difficult
to change if the correct procedure is not followed. Refer
to the following instructions when changing tires. Note
that center section tires can be changed while the
machine is in transport position, however if at all
possible lower the unit into field position before
changing center section tires.
1. To ensure safety when jacking the unit, each wheel
standard is equipped with a jack stand mount. Using
a minimum of a 10 ton hydraulic jack and the
necessary blocking, jack the implement until the
weight is relieved from the walking axle. Refer to the
figure for the for jack stand mount location.
2. If any wing tire or center section outside tires are being
changed, remove the wheel bolts and replace the tire.
If any of the center section inside tires are being
changed, the walking axle must be separated from the
wheel standard before the tire can be removed. To
separate the walking axle remove the 5/8" x 1 13/16"
round u-bolts as shown.
3. Manoeuver the wheels and walking axle out from
under the unit. Change the tire.
4. Reposition the wheels and walking axle and bolt in
place. Replace the 5/8" locknuts with new locknuts.
Be sure to use the identical type of locknuts that were
removed from the machine (i.e., one way locknuts
only). Torque the nuts to 217 N-m (160 lbf-ft).
