6.15 Axle Maintenance
Tightening and retightening wheel nuts
The following points should be followed for tightening and retightening of wheel
nuts:
1. Impact wrenches should not be used as the impact torque maybe
excessive.
2. Wheel nuts should be tightened diagonally every time in conjunction
with a torque wrench.
3. In the case that power tools are only available, they must be set to the
correct torque (check heading 6.10), as it may cause damage or
breakage to occur due to over tightening.
The following periodical intervals should be taken to ensure nuts are correctly
tightened after:
1. The first time of use.
2. The first laden journey.
3. The first 1000km.
4. Every six months thereafter or every 25,000km respectively.
5. Repeat every time a wheel is changed or removed (check how to safely
remove a wheel heading 6.11)
Hubcaps that become missing or damaged must be replaced immediately to
avoid dirt penetrating into the hub, which can cause damage to the bearings.
Check hub caps are always in place, and that they are in a good condition.
If the hubcaps are a press fit, check visually they are fully home.
If the hubcaps are attached using screws, fit a new gasket if needed once the
hubcap is removed.
Retighten the screws regularly every 6 months.
The bearing play should be checked after
1. First 1,000km.
2. Before intensive use every 6 months or 25,000km.
Wheel bearings are subject to wear. Conditions which determine this are:
1. Operating conditions
2. The load
3. The Speed
4. Adjustment and lubrication.
Wheel bearings should be checked by:
1. Lift the wheel off the ground, and turn it slowly to check for any rough
points or friction.
2. Turn it at a high speed to check for unusual noises such as grating or
knocking.
If it is seen that there is damage or signs that the bearings are worn, both the
bearings and the seals should all be replaced.
