Abstract
A buffer system for a hydraulic hammer is disclosed. The buffer system includes a wear member disposed between a first component and a second component. The wear member includes a first surface. The first surface is adapted to abut an inner surface of the first component. The wear member also includes a second surface distal to the first surface. The second surface is adapted to abut an outer surface of the second component. The buffer system also includes an insert member disposed in the wear member between the first surface and the second surface thereof. The insert member provides a visual indication when a predefined thickness of the wear member between the first surface and the second surface is worn.

A buffer system for a hydraulic hammer, the buffer system comprising:
- a wear member including at least one plate that is disposed between a housing member and a power cell of the hydraulic hammer, the wear member comprising:
- a first surface of the at least one plate configured to abut an inner surface of the housing member;
- and
- a second surface of the at least one plate distal to the first surface, the second surface configured to abut an outer surface of the power cell;
- and
- an insert member disposed in the at least one plate of the wear member and extending between the first surface and the second surface of the at least one plate thereof, wherein the insert member provides a visual indication when a predefined thickness of the wear member between the first surface and the second surface is worn.
A hydraulic hammer comprising:
- a housing member;
- a power cell disposed within the housing member;
- and
- a buffer system disposed between the housing member and the power cell, the buffer system comprising:
- a wear member including at least one plate that is disposed between the housing member and the power cell, the wear member comprising:
- a first surface of the at least one plate configured to abut an inner surface of the housing member;
- and
- a second surface of the at least one plate distal to the first surface, the second surface configured to abut an outer surface of the power cell;
- and
- an insert member disposed in the wear member between the first surface and the second surface thereof, wherein the insert member provides a visual indication when a predefined thickness of the wear member between the first surface and the second surface is worn.
A buffer system for a hydraulic hammer comprising a housing member and a power cell disposed within the housing member, the buffer system comprising:
- a wear member including at least one plate that is disposed between the housing member and the power cell, the wear member configured to provide a clearance fit between the housing member and the power cell;
- and
- an insert member disposed in the at least one plate of the wear member, wherein the insert member provides a visual indication when a predefined thickness of the wear member is worn, and
- wherein the insert member is molded to the wear member.
