摘要： A wheel balancer having a central disc shaped body having a plurality of radial slots, extending from its central hub aperture through which the lug bolts of a brake drum may extend, the body being secured between the central disc of a wheel, also secured to the brake drum by the lug bolts. A circular tube filled with a liquid and small shot is secured to the body at its peripheral edge, the shot migrating to locations along the tube to balance out unbalance forces in the wheel when the wheel is rotating. The body of the wheel balancer is provided with breakoff tangs about the hub aperture between adjacent slots whereby the wheel balancer may be easily modified to be mountable on a brake drum whose hub cover is of a larger diameter.
