1. A wear assembly for an excavator comprising:

  • a base component fixed to the excavator and including a nose;

    a wear component having a wearable surface and a cavity to receive the nose, the wear and base components including aligned holes to form an opening having a peripheral shape; and

    a lock removably received in the opening for releasably holding the wear component to the base component, the lock including a body and a locking member mounted to the body for rotational movement about an axis between a release position and a locking position, the body and the locking member cooperatively defining an outline shape about the axis with the locking member in the release position so that the lock is received within the peripheral shape of the opening when inserted therein generally in an axial direction, the locking member being at least partially outside of the outline shape when in the locking position such that at least part of the locking member sets opposite an inner surface formed in the opening to prevent removal of the lock from the opening, and the body and the locking member cooperatively defining an axial length that is the same in each of the release and locking positions so as to position the lock in each said hole when the lock is installed in the opening free of substantial axial pressure.
