Maintenance
Row hubs
NOTE
When the existence of looseness is noticed, it is necessary to make the maintenance
in the hubs of the disc blades, unaligned double discs, gauge wheels and press wheels.
Disassemble the hubs and remove the internal components.
Clean all parts with a specific degreaser for the maintenance operation.
Verify the existence of looseness and the conditions of bearings, retainers and bushings.
Replace the damaged components or with excessive wear.
The hubs without grease fittings should be assembled with a good amount of lubricant
on the inner part of the hub.
The hubs should rotate with the hand applying a small effort.
• Whenever the bearings are replaced, it will be necessary to change the sealing
rings and o-rings as well.
• Fill up the inner part of the hub with grease and put the cover (A) using an
elastic ring.
