Systems and methods can include applying, using a nut assembly including a first nut and a plurality of fasteners provided in respective threaded holes of the first nut, a first tensioning force for a stud of a hammer assembly. The systems and methods can also include applying, using the nut assembly, a second tensioning force for the stud of the hammer assembly. The first tensioning force can be applied with the first nut in a first orientation whereby a first end surface of the first nut faces a first direction and a second end surface of the first nut faces a second direction opposite the first direction. The second tensioning force can be applied with the first nut in a second orientation whereby the first end surface of the first nut faces the second direction and the second end surface of the first nut faces the first direction. The second tensioning force can be greater than the first tensioning force.

Systems and methods for assembling or disassembling a hammer tool

A work tool coupling assembly for a machine with a working implement. The work tool coupling assembly can include an excavator stick and a pin grabber coupler. The pin grabber coupler can include a first plate, a second plate, and a middle plate positioned between the first plate and second plate. The middle plate includes a portion protruding away from the first plate and second plate and is coupled to the excavator stick by a stick pin. The middle plate, the first plate, and the second plate are configured to couple with the working implement.
