A diagnostic system for measuring acceleration of a piston of a reciprocating hammer is disclosed. The diagnostic system may include a magnet configured to induce, via electromagnetic induction and based on a movement of the piston, an electric current in a conductor. The diagnostic system may include a capacitor electrically coupled to the conductor and configured to store electric power based on the electric current induced by the magnet. The diagnostic system may include an accelerometer configured to measure an acceleration of the piston. The diagnostic system may include a communication device powered by the capacitor and configured to output a signal that identifies the acceleration measured by the accelerometer.

A wear member for attachment to a surface of a machine is provided, the wear member a body having an outer layer and a base layer. The outer layer including a plurality of channels formed in an outer surface. The base layer is attached to an inner surface of the outer layer. The base layer is divided into a plurality of base layer pieces, each of the plurality of base layer pieces including at least one interfacing edge. The plurality of base layer pieces are assembled together such that each interfacing edge of each of the plurality of base layer pieces is opposite an interfacing edge of another of the plurality of base layer pieces so as to define at least one gap therebetween.

A self-charging assembly having a first side wall, a second side wall, a third sidewall, a first chamber, a second chamber, a first valve assembly, and a second valve assembly. The second side wall is disposed within the first side wall. The third sidewall connects the first side wall and the second side wall. The first chamber is defined by the first, second, and third sidewalls. The second chamber is disposed within the first chamber and is defined by the second side wall. The first valve assembly is configured to selectively place an interior portion of the second chamber in communication with an atmosphere outside of the self-charging assembly. The second valve assembly is configured to selectively place an interior portion of the first chamber in communication with the interior portion of the second chamber.

A hard link, which is connected to a moldboard of a machine, includes a first range of float capability and a second range of float capability. The second range of float capability may provide a greater float height to the moldboard than the first range of float capability. In another embodiment, a machine includes a moldboard, a jib arm operatively configured to raise and lower the moldboard, and a link attaching the jib arm to the moldboard. The link includes two discrete float capabilities.
