1. A combination starter-generator device for a work vehicle having an engine, the combination starter-generator device comprising:
a housing arrangement forming a reaction member;
a gear set configured to transmit power flow to and from the engine;
a clutch arrangement configured to selectively interact with the gear set to modify power flow through the gear set;
an actuator device having an armature, the actuator device operable to power movement of the armature in a first axial direction to apply a push force;
a linkage coupled between the actuator device and a portion of the clutch arrangement, the linkage having a first end proximal to the reaction member, a first portion extending from the first end, and a second portion extending radially from the first portion to a second end, the first portion having a neck region formed as a permanent bend having a bend radius, and the second portion having a coupling region configured to interact with the armature, a stiffened region, and a connection region at the second end, wherein the stiffened region includes one or more flanges; and
an actuation pin connected to the connection region and the portion of the clutch arrangement,
wherein the linkage is formed from a flexible resilient material and is movable in a powered stroke from an undeformed, unloaded condition to an elastically deformed, loaded condition by application of the push force, and is movable in a return stroke from the elastically deformed, loaded condition to the undeformed, unloaded condition under an elastic return force with the push force removed,
wherein the second end is displaced in the first axial direction or a second axial direction in the powered stroke to reposition the portion of the clutch arrangement in the same one of the first axial direction or the second axial direction, and
wherein the second end is moved in the other of the first axial direction or the second axial direction in the return stroke to reposition the portion of the clutch arrangement in the same other of the first axial direction or the second axial direction.
