A balance assembly (58) for rotary turbine components, such as turbine rotors (14) , as well as method for installing and/or adjusting at least one balance weight (66) in the balance assembly (58) and turbine section (10) having this balance assembly (58) and a radially extending access pathway (300, 304, 308, 312) for accessing this balance assembly(58). The balance assembly (58) comprises; (a) a balance weight retention member (62) having a circumferential periphery (92) and a slot (90) formed therein along at least a portion thereof, the slot (90) having: (1) a bottom surface (94); (2) an opening (98); and (3) a pair of spaced apart and opposed side walls (102, 106) connecting the bottom surface (94) and the opening (98), the side walls (102, 106) sloping inwardly between the bottom surface (94) and the opening (98) to define a balance weight engaging section (114); (b) at least one balance weight (66) configured and sized to be insertable through the opening (98) of the slot (90) and to be positionable for movement within the slot (90) and having a pair of spaced apart generally inwardly sloping shoulder surfaces (152, 156) capable of engaging the side walls (102, 106) of the slot (90) at the balance weight engaging section (114); and (c) a balance weight securing member (70) associated with the at least one balance weight (66) that can be actuated to: (1) move the at least one balance weight (66) away from the bottom surface (94) so that the shoulder surfaces (152, 156) engage the side walls (102, 106) at the balance weight engaging section (114) such that the at least one balance weight (66) is in a secured position within the slot (90); or (2) move the at least one balance weight (66) towards the bottom surface (94) so that the shoulder surfaces (152, 156) do not engage the side walls (102, 106) at the balance weight engaging section (114) such that the at least one balance weight (66) is in a unsecured position within the slot (90).
