Transmission Sub-Assembly for a Multi-Mode Drill

A multi-mode drill including a transmission (22) to transfer torque from an output member of a motor (20) to an output spindle (40). A transmission housing encloses the transmission (22) in an interior cavity formed by a gear case shell (149) and a cover plate (150). The cover plate (150) can be coupled to the outer shell (149) via screws. A static shift rod (144) can be supported at one end by the cover plate (150). A shift bracket (132) can be mounted on the shift rod (144) and biased to a mode position by a biasing member (148) exerting a force between the shift bracket (132) and the cover plate (150). A shift pin (92) can be supported adjacent one end by the cover plate (150) and biased to a mode position by a biasing member (148) exerting a force between the shift pin (92) and the cover plate (150). A spindle biasing member can bias the output spindle (40) against the cover plate (150). The shift pin (92) can actuate an electronic switch (178). A motor housing can be coupled to the transmission housing with fasteners so that the cover fasteners are not accessible.
