Systems and methods for assembling or disassembling a hammer tool

Abstract:

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.
