Table 16. 6 – 7 illustrations‘ tightening information
Picture 12. Wheel mounting with centring on hub can be facilitated by the introduction, at least in two columns, of the
indicated centring rings, reference 1 in the illustration. This is useful especially when mounting twin wheels since the disc offset could
make hub positioning problematic.
7.1.2.
Maintenance of axles
Constantly check the tightening of the hub covers. Any lost or damaged cover must be replaced in
order to protect the hub against the penetration of dirt. When replacing screw-able covers, the spacer should
also be replaced. The cover shall be tightened up regularly (every 3 months).
