The Tiger Tool Bearing Race Starter Kit is a patent-pending design where bearing races can be removed precisely and installed in minutes on aluminum and steel hubs. The split ring is forced to expand over the wedge, increasing the diameter of the ring until it clamps onto the bearing race, easily pulling it free. A shop press is applied to the adapter kit assembly to remove and install a variety of bearing races. The Bearing Race Starter Kit provides a safer alternative to welding, hammering, and punching methods, says the company.
