Maintenance of the row hubs
• When the existence of looseness is noticed, it is necessary to make the maintenance
on the row hubs.
• Disassemble the hubs and remove its internal components.
• Clean all parts with diesel oil or kerosene.
• Verify the existence of looseness and the conditions of bearings, retainers and
bushings. Replace the damaged components or the ones with excessive wearing.
• The bearing must be changed on a preventive manner to avoid that it breaks and the
equipment unavailability, as well as a greater maintenance cost, as more parts of the set
will be damaged when the bearing breaks up during the job.
• The hubs with grease fittings should be lubricated until the new grease is visible.
• The hubs with tapered roller bearings fastened by castle nut and cotter pin allow the
adjustment of the inner clearance; excessive tightening should be avoided. The hubs should
rotate with the hand applying a small effort.
