DANGER
• NEVER use force on an inflated or partially inflated tire. Make sure the tire is correctly seated before
inflating to operating pressure.
• Do NOT remove, install, or make repairs to a tire on a rim, unless you have the proper equipment and
experience to perform the job. Take the tire and rim to a qualified tire repair shop.
• If the tire is NOT in the correct position on the rim or if too full of air, the tire bead can loosen on one
side, causing air to leak at high speed and with great force. An air leak of this nature can thrust the tire
in any direction, endangering anyone in the area.
• To avoid severe personal injury or death caused by machine runaway, shut off engine and remove key
before performing any of the following checks and/or adjustments.
Check tire pressure every year. Caster tire pressure should be 69 kPa (10 psi).
To maintain pressure, visually check daily that tires have not lost pressure, and adjust pressure as needed.
Underinflation of tires can cause sidewall cracks.
NOTE:
If caster wheels shimmy, a possible cause is overinflation.

Tightening Caster Wheel Nuts
At first use or when a wheel is removed, check wheel nut/bolt torque every 15 minutes on the road or 1 hour in the
field until the specified torque is maintained.
Once specified torque is maintained, check wheel nut/bolt torque after 10 and 50 hours (field or road operation) and
then at 200 hour intervals thereafter.
To tighten the caster wheel nuts on either forked or formed caster wheels, follow these steps:
Figure 5.215: Forked Caster Wheel Nut
Tightening Sequence
1. Position wheel assembly on hub and install wheel
bolts (A).
2. Tighten wheel nuts (A) to 163 Nm (120 lbf·ft) using the
tightening sequence for the type of caster wheel shown
in the illustrations at right. Repeat the tightening
sequence three times.
