11.15.2 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 8.7), 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 8.9)
11.14.3 Hubcap Maintenance
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.
11.14.4 Bearing Play
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.
