A lower bead breaker quick release for a tire changing machine includes a manually overpowered spring lock mechanism that keeps the lower bead breaker in position during normal lower and upper bead breaking operations. Manual compression of the spring lock allows the lower bead breaker pivot shaft to be positioned axially to allow complete removal of the lower bead breaker from the tire changing machine. A manually actuated, friction locked lower bead breaker attitude adjustment is also provided. |
