FIGURE 5.4 Sequence of nut tightening
(1) - (10) sequence of nut tightening, (L) spanner length, (F) user weight
Checking the wheel nut tightening:
•
after first use,
•
after first travel with load,
•
after travelling the first 1,000 km,
•
every six months of use or every 25,000 km.
In the event of intensive work check the nut tightening at least every 100 km. The above
actions should be repeated individually if a wheel has been removed from the wheel axle.
ATTENTION
Wheel nuts must not be tightened with impact wrench because of danger of exceeding
permissible tightening torque, the consequence of which may be breaking the connection
thread or breaking off the hub pin.
The greatest precision is achieved using a torque spanner. Before commencing work,
ensure that correct tightening torque value is set.
