The wheelset hubs must be lubricated every 150 hours. When there is any clearance,
it is necessary to give maintenance to the wheelset hubs.
Disassemble the hubs and remove the inner components. Clean all parts with diesel
oil or kerosene.
Check the existence of clearances and the condition of the bearings and retainers.
Replace any damaged component or with excessive wear.
The bearing must be replaced in a preventive way to avoid breaking it and the
unavailability of the equipment, as well as a higher cost for repairing it, because when the
bearing breaks during working, more parts of the set gets damaged.
Check the retainer (A) position to allow that the excess of grease gets out and be
careful to not damage it.
Adjust the castle nut (B) from the hub using a wrench until reaching a small resistance
while turning the hub. Do not overtight. Lock using a cotter pin (C).
Place the protective cover (D) and lock using a bolt (E) and spring washer. Fasten the
grese fitting (F) on the protective cover.
Whenever the retainer is damaged, replace it immediately.
Do not forget to apply the specific grease for this equipment, that is a lithium soap
grease, grade NLGI 2 with Extreme Pressure additive, anticorrosive and antioxidant.
