Maintenance
Wheelset hubs lubrication
The wheelset hubs must be lubricated every 150 hours. When the existence of any
clearance is noticed, carry out a maintenance on the wheel hubs.
Disassemble the hubs and remove their internal components. Clean all parts using
diesel oil or kerosene.
Check the existence of clearances, the condition of the bearings, retainers or bushings.
If there is any part that shows excessive wear or damages, replace them.
The bearing must be replaced in a preventive manner, to avoid that it breaks and to
avoid greater maintenance costs, since more parts of the set suffer damages when the
bearing breaks during the job.
• For models with 400/60 x 15.5 tires - 14 ply
Check the retainer position (A) to let the excess of grease flow out of the hub and be
careful to not damage the retainer.
Adjust the flat washer (B) and the castle nut (C) on the hub using a wrench to get
some resistance while turning the hub. Do not totally tighten it. Lock it using a cotter pin (D).
Place the hubcap (E) and lock using a bolt (F) and spring washer. Lastly, attach the
grease fitting (G) on the hubcap.
