A motorized drum (03000) has a drum shell (03700) with a motor (04200) there within and an end lid (03570) of a determined diameter with an end lid recess (46920). An end lid remover tool (46940) has an outer circumferential geometry with a larger diameter and a tool recess (46930). The tool recess complements the end lid recess. A joining cord (46910) has a cross-sectional geometry that corresponds to the combination of the end lid recess and the tool recess. An inlet enables access to the channel, and a flexible member (46910) is installed therethrough to occupy the channel. A slide hammer (46950) applies an axially outward force whereby the end lid is urged axially outward in response to outward force conveyed to the end lid arrangement via the flexible member. The remover tool can have alternatively a circumferential spiral geometry that is configured to engage an outer circumferential spiral geometry of the end lid.
