MAINTENANCE AND SERVICING
Measure tire pressure with a gauge every year. Caster tire pressure should be 10 psi (69 kPa).
To maintain pressure, visually check daily that tires have not lost pressure, and adjust pressure as needed.
Under-inflation of tires can cause side wall cracks.
NOTE:
If caster wheels shimmy, a possible cause is over-inflation.

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.
Continue with a checking schedule of 10 and 50 hours (field or road operation) and then every 200 hour
intervals thereafter.
To tighten the caster wheel nuts on either forked or formed
caster wheels, follow these steps:
1. Position wheel assembly on hub and install wheel
bolts (A).
2. Tighten wheel nuts (A) to 120 ft·lbf (163 N·m) using
the tightening sequence suitable for the type of caster
wheel shown at right. Repeat the tightening sequence
three times.
