Wheel Assembly
Wheel Bearings
The wheel bearings for the baler must be cleaned and
lubricated at the beginning of each season. See the
Specifications division for the correct lubricant.
Sealed Bearings
Sealed bearings are lubricated for life. Because of the
type of seal, lubricant cannot be added. If a seal is
damaged, the sealed bearing must be replaced.
Wheel Bolts
Tighten the wheel bolts after every 50 hours of operation.
See the Specifications division for the correct torque.
The wheels are fastened to the hubs with wheel bolts
installed in threaded holes in the hub flange. When
installing a wheel, clean the threads of the wheel bolts
with a steel brush and oil lightly to retard corrosion.
