| Balancing on a static wheel balancer |
Note | Attaching the wheel onto the wheel balancer |
Note | As for any other repair, cleanliness is of the utmost importance during the balancing process. It is essential for obtaining satisfactory results. |
| Dirt and rust in the contact areas and the centre opening of the wheel may distort the results. |
| –
| Clean the contact surface, the centre opening and the wheel rim plate before positioning the wheel on the balancing equipment. |
| –
| Fasten the whole wheel on the balancer. |
| Procedure for balancing the wheel rim / tyre |
| –
| Lower the wheel balancing equipment protection cover. |
| –
| Turn the wheel or tyre on the balancer. |
| –
| Check the tyre tread while turning the wheel. |
Note | Balancing will not eliminate noise due to lateral wear, flattening or significant wear in the tread indicator. In this case, the tyre should be replaced. |
| –
| Check the concentricity of the wheel / tyre. |
| If not all the wheel turns in a concentric manner, and if no flattening has been detected, there may be radial or axial run-out. |
| –
| Check the radial and axial run-out of the wheel → Chapter. |
| If the radial and axial run-out do not exceed the permitted tolerance levels, balance the wheel and the tyre. |
Note | t
| Do not attach counterweights of over 60 g to the wheels. |
| t
| If a greater counterweight is required, the tyres should be “Match balanced” → Chapter. |
| t
| The display on the balancing equipment should read 0 grams. |
| –
| Fit the wheel on the vehicle and tighten the bolts to the required torques → Chapter. |
| –
| Test drive the vehicle after balancing. |
| If any imbalance is detected during the test drive, this may be due to tolerances in the centre of the wheel. |
| In unfavourable circumstances, the tolerances of the wheel components and the wheel hubs may be added together, this can also cause imbalance while driving. These can be removed with a finish balancer → Chapter. |
