Multi-mode drill and transmission sub-assembly including a gear case cover supporting biasing

A multi-mode drill comprising:

• a motor with an output member;
• an output spindle driven by the output member of the motor;
• a transmission being configured to transfer torque from the output member of the motor to the output spindle;
• a transmission housing that encloses the transmission in an interior cavity, the interior cavity being formed by a gear case shell and a cover plate, the cover plate coupled to the outer shell via at least one cover fastener;
• a shift pin supported adjacent one end by the cover plate, the shift pin being moveable between a first mode position and a second mode position;
• a biasing member contacting the cover plate and exerting a biasing force against the cover plate and which acts on the shift pin tending to move the shift member toward the first mode position.

A multi-mode drill comprising:

• a motor with an output member;
• an output spindle driven by the output member of the motor;
• a transmission being configured to transfer torque from the output member of the motor to the output spindle;
• a transmission housing that encloses the transmission in an interior cavity, the interior cavity being formed by a gear case shell and a cover plate, the cover plate having an attached position which closes an opening of the gear case shell wherein the cover plate is coupled to the gear case shell via at least one cover fastener;
• a static shift rod supported at one end by the cover plate;
• a shift bracket mounted on the static shift rod, the shift bracket being movable between a first mode position and a second mode position;
• a biasing member retained in a compressed state by the cover plate when the cover plate is in the attached position, and in the compressed state the biasing member generates a biasing force acting on the cover plate which tends to move the shift bracket toward the first mode position.
