At least one wear indicator 44 is provided on the side surface of a jaw 16, hook or latch 26 of a coupler (10, fig 1), wherein the coupler has a first half (12, fig 1) for attachment to an excavator and second half (18, fig 1) for attaching an accessory to the coupler. Wear indicators may protrude or be etched into the side surface of the coupler. A coupler jaw may have a curved upper wall profile 50, and wear indicators may be curved to follow the curvature of the jaw. Wear indicators are intended to allow an operator to determine when a part of the coupler may need to be replaced. |
