If any damage is found, the wheel or tire should be replaced before balancing. Next, remove any loose debris, such as stones or nails, from the tire treads. Clean the wheel mounting surfaces to ensure proper contact with the balancer's spindle. This step is vital for accurate readings, as any dirt or debris can cause the wheel to be mounted improperly, leading to false imbalances. Once the wheel is prepared, it's time to mount it onto the wheel balancer. Most balancers use a cone-and-cup system to center the wheel on the spindle. Select the appropriate cone size for the wheel's center bore and slide it onto the spindle. Then, carefully lift the wheel and slide it onto the cone, ensuring that it sits flush against the balancer's mounting flange. Install the outer cup and tighten the spindle nut to secure the wheel. The nut should be tightened to the manufacturer's specified torque to prevent slippage during the balancing process. After mounting the wheel, the balancer needs to be set up with the correct wheel parameters. These parameters typically include the wheel's width, diameter, and offset (or backspacing). Modern computerized wheel balancers often have automatic data entry systems that use sensors to measure these parameters. However, on older or manual balancers, these measurements need to be entered manually. Accurate data entry is critical for precise balancing, as the balancer uses these values to calculate the correct amount and placement of balance weights. With the wheel mounted and the parameters set, the balancing cycle can be initiated. The balancer will spin the wheel at a high speed and use sensors to measure any imbalances. The results are displayed on the balancer's screen, showing the amount of weight needed for each side of the wheel and the locations where the weights should be applied. These locations are typically indicated by marks or lights on the balancer. Once the balancer has provided the measurements, the appropriate weights need to be attached to the wheel. There are two main types of balance weights: clip-on weights and adhesive weights. Clip-on weights are attached to the wheel's rim flange, while adhesive weights are stuck to the inside of the wheel. The type of weight used depends on the wheel design and the balancer's instructions. When attaching the weights, ensure that they are securely fastened and properly positioned. For clip-on weights, use a hammer and specialized pliers to crimp the weight onto the rim. For adhesive weights, clean the application surface with a suitable solvent and press the weight firmly onto the wheel. After attaching the weights, it's good practice to perform a test spin to verify the balance. If the balancer still indicates an imbalance, minor adjustments may be needed. This might involve adding or moving weights slightly to achieve perfect balance. In summary, the common operational procedures of a wheel balancer involve careful inspection, proper mounting, accurate data entry, weight attachment, and verification. Following these steps diligently will ensure that wheels are balanced correctly, contributing to a smoother and safer driving experience.
