Hofmann 1200 Wheel Balancer Manual
Hofmann tire balancers and wheel balancers use pieces of specialized equipment in order to accurately determine deflections in balance and to correct them. Unbalanced tires can lead to many problems on the road, making wheel balancer accuracy highly important. Auto shops typically use one of three different kinds of tire balancers, which include the following:. Static balancer: This type is frequently used by more traditional auto mechanic shops. These work by sensing which angle off of the center line is unbalanced. Static balancers use gravity to move a cone that sits on top of the tires to move in the direction of the unbalance. A glycerin-filled chamber with a bubble is on top of the cone.
The bubble will move in the opposite direction of the unbalance. Dynamic on-the-car spin balancing: This method is one of the most accurate ways of balancing tires and requires caution. To use it, the tires and wheels are left on the vehicle. Then, a part similar to a hat is placed on the wheel with a clamp to stay in place. The wheel is then made to spin for a time by placing a motor next to it.
Inside the hat-like part, balance mechanisms show where an unbalance is present. A technician must hold six friction rings in place for them to reveal an ideal balance. This method has a high rate of accuracy due to the fact that the wheels and tires are spun directly on the car, which will account for any specific issues with the vehicle.

Dynamic high-speed spin balancing: The dynamic high-speed balancing machine is the most commonly used in auto shops. Using a set of cups to make sure the hub is centered, both the tire and wheel are placed on the balancer. The offset, width, and diameter are entered by a technician into the machine. The machine then spins the tire to reach an operating speed of around 60 mph. That shaft is then calibrated and runs into the balancing machine. The machine’s computer then shows where the deflection is located and provides the results on an LED screen. Weights are applied, and the technician will make the wheels spin again to double check that the weight placement is correct.
