6.4.3.2 TIGHTENING AND RETIGHTENING WHEEL NUTS (SUMMARY):
Never use impact wrenches to tighten the wheel nuts as the impact torque may be excessive.
Wheel nuts should be tightened diagonally using a torque wrench.
If power tools are used (for example, pneumatic torque wrench) they must be carefully set to the required torque for tightening.
Otherwise, the studs and wheel nuts may be over tightened which may damage or break them.
Retighten the wheel nuts after:
- The first time of use.
- The first laden journey.
- The first 1,000 km.
- Every 6 months or 25,000 km.
Repeat every time the wheels are changed or removed.
6.4.3.3 CHECKING THE HUBCAPS
Missing or damaged hubcaps must be replaced immediately to avoid dirt penetrating into the hub which might result in damage to
the bearings.
Check that the hub caps are in place and in perfect condition.
For press fit hubcaps, check visually that they are fully home.
For hubcaps attached using screws, fit a new gasket if necessary when the hubcap is removed and retighten the screws regularly
(every 6 months).
6.4.3.4 CHECKING THE WHEEL BEARING PLAY
- After the first 1,000 km.
- Before intensive use, every 6 months or 25,000 km.
Wheel bearings are subject to wear: their lifetime depends on the operating conditions, the load, the speed, the adjustment and
lubrication, etc.
To check the wheel bearings:
- Lift the wheel off the ground.
- Turn in both directions slowly to check for any rough points or friction.
- Turn it at high speed to check for unusual noises, such as grating or knocking.
If the bearing is damaged or worn, the bearing and seals should all be replaced (see Section 6.4.3.7 REPLACING THE WHEEL
BEARINGS).
1. To check the wheel bearing play, raise the axle until the wheel is no longer resting on the ground (ensure that the vehicle
cannot move) .
2. Release the brake, grip the wheel at the top and the bottom and check the play by trying to tilt it. The play can also be
detected by using a lever between the wheel and the ground.
If you can feel any play, adjust the wheel bearing (see paragraph 6.4.3.5 ADJUSTING THE WHEEL BEARINGS).
Make sure that the play does not come from the suspension or a steering axle kingpin.
