Zusammenfassung:	A hydraulic hammer having a front head and a lower bushing is disclosed. Also disclosed is a system and method for easily removing the lower bushing from the front head. The front head of the hydraulic hammer may define a bore therein and an inner surface of the bore may have a first taper. The lower bushing of the hydraulic hammer may be capable of being positioned within the bore of the front head and an outer surface of the lower bushing may have a second taper, with the first taper substantially following the second taper. La présente invention se rapporte à un marteau hydraulique possédant une tête avant et un manchon inférieur. L'invention décrit également un système et un procédé destinés à retirer facilement le manchon inférieur de la tête avant. La tête avant du marteau hydraulique peut délimiter un trou dans celle-ci et une surface intérieure du trou peut présenter un premier rétrécissement. Le manchon inférieur du marteau hydraulique peut être positionné dans le trou de la tête avant et une surface extérieure du manchon inférieur peut présenter un second rétrécissement, le premier rétrécissement suivant sensiblement le second rétrécissement.
