Abstract
A digging tooth assembly has a base nose, a replaceable tooth tip mounted on the base nose and a pin securing the tip to the nose. The pin includes a locking head eccentric to the pin and a pad-like resilient member is placed between the head and the tooth tip. The locking head is rotated so that the resilient member is compressed to urge the tooth tip in a direction such that the tip is maintained in a nose-contacting position.
