Abstract
A tip and adapter assembly for an earthworking bucket has a replaceable tip mounted on an adapter. The adapter has a mounting end fitted into a socket cavity of the tip, which are provided with suitable mating surfaces for transferring loading forces from the tip to the adapter. The adapter is provided with an ear that projects into a U-shaped notch in each side of the tip. A gap is provided between the ear and the notch to indicate that excessive wear has not occurred in the tip/adapter interface. However, contact between the ear and notch serves as a visual indicator that excessive wear has occurred. The notch also serves as a fuse to ensure that the tip breaks due to excessive loads before the adapter.
