5.3.4 ALKO EURO Axles are equipped with maintanance free compact bearings

If necessary, adjust the axial play of the wheel bearing
- Remove the decoration and the wheel-hub cap.
- Remove the split-pin from the castellated wheel nut.
- Tighten the nut while spinning the wheel until a resistance is felt. If possible use a torque wrench
(50 Nm).
- Turn the castellated nut 1/12 of a turn (30°, see diagram 1) then turn back to the next pin
alignment position.
Axial play to 0.05 mm is acceptable.

Overtightening will cause bearing damage
- Check grease for quantity and condition, top-off or renew, if necessary
- Grease type for wheel bearings: Multi-purpose grease DIN 51825 KTA3K
- Replace wheel hub caps
