5.4
Repeat the inspection procedure for other wheels, remembering that the lifting
jack must be on the side opposite to the chocks.
If play is felt, adjust bearing. Unusual sounds coming from bearing may be symptoms of
excess wear, dirt or damage. In such an event the bearing, together with sealing ring, should
be replaced with new parts, or cleaned and greased again During inspection of bearings
ensure that possibly detected looseness comes from the bearing and not from the
suspension system (e.g. looseness of leaf spring pins etc.).
TIP
Damaged hub cover or lack of hub cover causes penetration of contamination and
dampness to hub, which causes significantly faster wear of bearing and hub seals.
Bearing life is dependent on working conditions of trailer, loading, speed of travel and
lubrication conditions.
Check condition of hub cover, if necessary replace with new cover. Inspection of bearing
looseness may only be conducted, when the trailer (without load and load box) is hitched to a
tractor.
Check wheel axle bearings for play:
•
after passing the first 1,000 km,
•
after intensive use of trailer,
•
every six months use or every 25,000 km.
5.2.3 ADJUSTMENT OF WHEEL AXLE BEARINGS LOOSENESS
The wheel should turn smoothly without stiffness or detectable resistance. Adjustment of
bearing play may only be conducted, when the rotary rake is hitched to a tractor.
